5″ x 7″ High Reduction Ratio Jaw Crusher

The 911MPE-TM-T is a Jaw Crushers for Coarse Primary Crushing and Mid Range Primary Crushing. This jaw crusher is equipped with a standard 5 HP motor and a 5″ X 7″ jaw cavity that will produce a discharge crushed product of under <1mm.

Well-proven single toggle, high reduction Jaw Crushers. The crushing capacity and the end-fineness of the sample material depend on the type of crusher and on the breaking characteristics of the sample material. Designed for laboratory applications and for operating environments and accepts soft to hard ores, drill cores, rocks, alloys, slags, soils, ceramics, and similar hard and brittle materials.canada manufacturer

The Jaw Crusher 911MPE-TM-T is used for the rapid, effective crushing and pre-crushing of medium-hard, hard, brittle and tough materials. Its variety of materials offered, including heavy-metal free steel, its efficiency and safety makes it ideal for sample preparation in laboratories and industrial plants. For small amounts of sample the 911MPE-TM-T is used batchwise; for larger amounts it can be operated continuously. Control of the gap width and zero point adjustment allow for reproducible results.

This performance jaw crusher can be inline unit (within your process) or stand-alone. With inline units we need to provide a control box, often also a different frame and inlet.  Depending on the application stand-alone units can also need a different frame and/or inlet.

Jaw Crusher Principle of Operation

The 911MPE-TM-T Jaw Crusher is used by laboratories and processing companies to crush solid materials such as rocks or soil and ores.
The material to be processed falls into the crushing chamber of the 911MPE-TM-T Crusher via a guide chute and is crushed by crushing action of a static and a dynamic jaw plate until it passes the pre-selected gap of the crusher.

Easy cleaning and operation

The 911MPE-TM-T jaw crusher can be used for small volumes batchwise or in a continuous mode for bigger volumes. You can easily change the movable and static jaw plates as well as the side liners.

Gap setting

The desired gap can set up easy and reproducible by spacer.

JAW CRUSHER Installers and Users

The AUTOLUBE system of this Jaw Crusher is programmed to be active for one minute every sixty minutes regardless of how many times you start and stop the machine!

To prevent your machine from trembling or moving from its set position, place the supplied rubber mat underneath it.



Jaw Crusher Dust Collecting Hopper

If the dust collecting hopper was ordered, it should be installed between the bottom of the machine and stand, in the back, with the two (2) screws in the sides already in place. Remove the screws, insert them in the eyes of the hopper, and tighten.

One Year Limited Warranty

This Jaw Crusher is warrantied against defective materials or workmanship for one year from date of original purchase. This warranty is void if the product has been damaged by accident, unreasonable use, neglect, improper service, by not following the instructions in this owner’s manual, or other causes not arising out of defect in material or workmanship.



Jaw Crusher

Model #JCT#1AL

The lubrication system is set to grease the correct amount every 60 minutes irrespective of whether the machine is continuously operated or if it is stopped and started many times. Check regularly to refill it when the grease reservoir is at a very low level.

As grease, we recommend Lubriplate 1200-2 or any equivalent of the following heavy duty, non-corrosive extreme pressure, water resistant greases possibly containing molybdenum disulphides (N.L.G.I. No.2)

Esso – Unirex EP2
Shell – Darina XLEP2
Chevron – Ultiplex grease EP2



The transparent purge lines will not show grease exiting from the machine simultaneously. That is, because there are different size cavities within the machine that will allow the grease to accumulate for a long time before it is eventually forced to come out.

The air deflector plate (JCT144G) with time might become obstructed with grease and rocks accumulation. It is advisable to detach the duct from fan cover to rear duct (JCT006A) and through the opening remove all the air flow obstructing material.

Should the clamp JCT095J, with time show slippage from the set position, that might be caused by grease that has percolated where it grips. By spraying paint thinner or similar solvent that dilutes the grease and blowing it away, this can be easily corrected. In the worse cases the clamp needs to be removed and cleaned along with the cover of the bottom shaft (JCT087A).

Also, when setting the opening with the moving jaw it is essential to have the moving jaw bottom edge, below the one of the stationary jaw. If the moving jaw bottom edge is set above the stationary bottom edge, under heavy crushing conditions, the jaws will have the tendency to open up.

If your machine is supplied with a dust enclosure, the recommended air suction for dust extraction is 150cfm, although variation may be needed upon the mass of dust produced. It is recommended to have an air regulating (Butterfly) valve installed, since it is highly unlikely a dust extraction system will generate the proper volume.

Instructions For Releasing Clamp

The clamp is released with the adjustment Lever (JCT095Y) shown to the right.

Jaw Crusher Clamp

Slide holed side of the adjustment bar (JCT133) on to the lever (JCT095Y) and pull it to release the clamp (JCT095J).

Jaw Crusher Adjustment Bar

Before adjusting jaws, the nut and bolt must be released entirely as shown in the image below.

Jaw Crusher Adjusting

The opening between jaws can then be adjusted to the desired amount using the adjustment key shown to the right.

Jaw Crusher Adjustment Key

when finished, release lever, and tighten the nut and bolt.

Jaw Crusher Automatic Lubrication Motor 1

Jaw Crusher Auto Lube

Jaw Crusher Auto Lube Operating


To remove the motor (JCT165):

  1. Remove motor guard (JCT003).
  2. Release tensioned belts by undoing nuts on motor plate tensioner (JCT118).
  3. Remove belts (JCT139).
  4. Remove motor (JCT165) by undoing bolts holding it to motor plate (JCT117).

Removing flywheel (JCT011) (same procedure for drive pulley (JCT016)):

  1. Remove flywheel guard (JCT006).
  2. Open up locking plate lips (JCT009) for all screws (JCT007 & JCT008).
  3. Remove screw (JCT008), loosen up screws (JCT007) enough to allow insertion of a small plate and a ½” NC nut between the retaining plate of flywheel and the flywheel itself. Use a ½” bolt screwed in the nut through the hole in the retaining plate (JCT010) to force out the flywheel from the main excentric shaft (JCT055).

Disconnecting the pusher (JCT057) from the moving jaw (JCT065):

  1. Remove grinding jaws (JCT105/106).
  2. The moving jaw (JCT065) has the appropriate holes in the face for one to insert a ½” socket wrench and allen drive to start undoing bolts (JCT058). Afterwards, a bondus socket wrench in combination with a ratchet will speed up the process considerably (see Picture #1).

Moving jaw (JCT065) removal:

  1. To remove moving jaw from the machine, remove cover (JCT081A) by undoing screws (JCT082) with a normal socket wrench and pipe (see picture #2).
  2. Fasten the extractor/offset hub puller across offset sleeve (JCT077A) by using the threaded holes in the face (see Note 1). The bar will have two threaded holes ½” NC in line with the ones used, clearing the hub’s diameter. Now one can thread two bolts through the bar against the JC frame and pull out the hub. Make sure also to remove the pivoting shaft key (JCT079). By loosening the adjustment clamp one can now slide out the bottom shaft from the machine and remove the moving jaw.
  3. To pull out bottom shaft (JCT077) from cover (JCT087-1), first remove the two screws (JCT088A) and two screws (JCT088-1) from it. Then screw in two through the cover on the shaft’s face with at least ½” thread into the shaft and clearance of ½” between cover and screw’s head. Make sure that screws are protruding from cover’s surface at least the same amount. Set shaft vertically with cover up supported at the lower edge. If a press is available press down on the screw’s head that had previously been mounted on the shaft’s end. Otherwise, by using the same set up and a flat plate set onto the screw’s head, hammer them down thereby freeing the cover from the shaft.
  4. Now using a similar method one can press out the shaft from the offset sleeve.

Disassembling the moving jaw (JCT065):

  1. All bearings, top and bottom, are precision pressed in line into the moving jaw. The same procedure will be used to press them out.
  2. To replace old ones with new ones, proceed by pressing the top ones into the seats, one on each side and at the bottom two from each side.

Removing the pusher (JCT057):

  1. Prying out the frame’s insert (JCT146A) will greatly facilitate the pusher removal. Therefore, first remove flange A (JCT043) and then undo screws (JCT030) from flange B (JCT032). (See Note 1.) The insert will come out by:
    1) Removing support plate (JCT145K) by removing screws (JCT145J & JCT145F).
    2) Insert two round bars (½” diameter by 2-3/8″ long) into threaded holes ¾” NC on part JCT146A (see Picture #3)
    3) Screw in ¾” minimum thread screws. (For this purpose, custom made bolts are available from the factory without the need of ½” dia. x 2-3/8″ bars. Also read Note 1.) This will pry out the insert. Now the pusher can slide out from JC frame.

Pusher (JCT057) disassembling:

  1. Set the excentric shaft (JCT055) vertically and supports under cover side A. The shaft can be pressed out all the way since it has no shoulders. Remove covers. Press out first bearing on side A. Rotate pusher. Use a bar slightly smaller than the big diameter of the center’s bearing inner ring and press out side B bearing. Central bearing will be removed by pressing onto the bearing roller.
  2. Flange A (JCT043) and B (JCT032) are conventional bearing housings: If bearing replacement is necessary press them out, replace and re-pack with grease. At the reassembling stage, two important things to keep in mind:
    1) Reassemble pusher and press onto it excentric shaft (JCT055) and also flange B (JCT032). Slide assemblies into JC frame. Fasten flange B to frame with two 3/8″ NC bolts. This allows one to mount flange A on the opposite side in an easy manner, particularly when one has two longer 3/8″ NC bolts that will drive the flange into the frame’s seat. (See Note #1).
    2) The moving jaw must be re-assembled (if bearing replacement was needed) before being re-assembled into the JC. Being a relatively heavy piece some auxiliary lifting device might be necessary to lower it within the frame. All machines purchased and delivered before May 31, 2004 had been equipped with a sealing system made of parts JCT148, 149, & 150. After that date, a new improved seal (JCT148A) has been installed and it is fully interchangeable with all previous machines and is available for replacement. When replacing seals, first slide them onto covers (JCT065A) and then proceed in lowering the moving jaw within the JC frame until it has the lower bearing’s hole in line with housing’s 077B, 087, & 088 will be slid through the bearings and secured tightly with clamp (JC095J). Now, one can insert key (JCT079) onto the bottom shaft on the opposite side and by using a plastic mallet, hammer into place offset sleeve (JCT077A). Please note that in order to have the bottom shaft staying in place rigidly when assembling this offset sleeve it is sufficient to tighten the adjustment clamp on the opposite side.

Pusher installation and positioning:

  1. With everything bolted in place, that is, insert (JCT146A) and flanges (JCT032 & JCT043) it is very important to tighten first locknut (JCT018) on side A and then the locknut (JCT019) on side B. In both processes, it is advisable to screw on old ½” NC hexagon head bolt, preferably with same heavy duty washers, in between at the opposite end of the excentric shaft and hammer onto it while tightening the locknuts. One will notice the shaft’s lateral displacement until it will no longer happen and therefore the shaft will be correctly positioned.

Operating Sequence

  1. Pressure supply through internal passages moves piston “A” left while holding pistons “B” and “C” fixed. A measured quantity of grease discharges from Outlet 4.
  2. Piston “A” reaches end of stroke. It opens internal passages directing pressure supply to right end of piston “B”. Grease discharges from Outlet 1.
  3. Piston “B” reaches end of stroke. It opens internal passages directing pressure supply to right end of piston “C”. Grease discharges from Outlet 2.
  4. Piston “C” reaches end of stroke. It opens internal passages directing pressure supply to left and end of piston “A” which returns on its initial position as grease discharges from Outlet 3.

Starting Up the System

  1. Fill the grease lines with clean grease. An air driven pump works well for filling long grease lines. Fill the discharge line from the valve manifold to the bearings and also lubricate the bearings with a hand grease gun if possible.
  2. Fill the reservoir with clean grease.
  3. Loosen the grease lines at all valve manifold inlet outlets as well as at bearing injection points.
  4. Before starting the motor, check the following:
    ♦ System power requirements – voltage, phase, AC or DC, etc.
  5. Start up the system pump and progressively purge all parts of the system of air. Tighten the inlet fitting at the primary valve manifold. When the pump to the primary valve manifold line is free of air, repeat the operation at the bearing injection points.
  6. After the system has run for a while, check all connections for leaks.
  7. Observe normal system operating pressure, check if there is any excessive pressure peaks or dips which may indicate a tight bearing or valve manifold being distorted in mounting, or a loose or disconnected fitting.

To check if the auto lubrication system is functional

  1. Simply disconnect main grease line (235) from the grease reservoir or manifold and let the machine operate for more than one hour. There will be a teaspoon of grease protruding from the opening.
  2. Be aware that the pump operates only one minute every hour regardless how many times one starts and stops the machine. Therefore, if ever circumstances arise where there is doubt that the lubrication occurs, repeat the above operation to ascertain the situation.

How to Prevent Problems:

  1. Keep reservoir filled. A pump operating with an empty reservoir may force air into the system causing difficulty in building pressure or preventing the pump from priming.
  2. Use clean grease because foreign matter may clog pump filler screen. Keep filler screen and filler connection assembly clean.
  3. Inspect entire system regularly including all grease lines. Replace if damaged. Connections should be tight and a small amount of grease should be at the edge of each bearing.

How to Locate and Correct Problems:

  1. If there is air in the reservoir it is likely because the pump fails to build pressure. Correct this by cleaning out reservoir, adding a small amount of oil (this helps prime and purge system of air), and filling it with clean grease. To ensure that the system is free of air, cycle it several times and then open the lines at the valve manifold inlet outlets to bleed out the air.
    Remember that a fully pressurized grease system capable of operating properly is conditional to having removed all air and filled it with grease!
  2. Locate blocked points as follows:
    A. Open the pressure line at the inlet outlet to the manifold to check for blockage of the line to this point with pump operating. Grease should flow without the pressure opening the pressure check valve and releasing grease.
    B. Disconnect lines in an alternative sequence at the manifold. Grease should eject from each of the discharge outlets. If any of the outlets does not let out grease, the manifold is not functioning.
    C. If the manifold is O.K., reconnect the grease lines and check at the bearing connections that grease reaches them. With a manual grease gun and a grease nipple one can check each passage at the bearing grease outlets that there is no blockage causing the grease not to flow. If all checks out O.K., reconnect all lines and start the autolube system.

Autolube – Troubleshooting Wiring Connections

If the autolube system is not operational, it is possible that there is a wiring connectivity issue. Test wiring for continuity as shown in the steps below:

First remove the bottom cover plate from the autolube system (JCT353B). With the cover removed, unplug the motor cable connector as shown.

Jaw Crusher Wiring

Start by testing the cable connector on the side that leads to the motor. The two white wires on the end need to be checked for continuity as shown below. If there is continuity between these wires, this connection is not the cause of the issue. Proceed to the next step.

Jaw Crusher Wiring Connection

Next test the connections on the corresponding cable connector that leads out the side of the autolube housing. Both of these wires need to be checked for continuity. See pictured below:

Jaw Crusher Test the Connection

If testing is successful proceed to the next step.

Next test the cable that leads from the autolube system to the control panel. The two wires that need to be checked for continuity are the White (7) and green (6). See pictured below.

Jaw Crusher Control Panel 2

If all of the previous tests are successful, the last connection to check is the one at the PLC. Open the control panel and confirm that the white wire shown below is properly connected to the 12 port in the top of the PLC controller.

Jaw Crusher PLC Controller

If all of the wires covered in this instruction set are tested successfully, it is likely that the PLC controller is faulty.
