Its two dust extraction ports allow for safe removal of dust created in crushing samples. Roller gaps are adjustable to 2.54mm and access to drive components for maintenance and inspection is quick and easy via removable panels.

This Roll Crusher is fully enclosed for a safe and dust free working environment. Its rolls are powered by individual motors and it has an output capacity of 1814 kg/hour (4000 lbs/hr = 2 ton/hr).

The machine weighs 455 Kilos and has 2 motors, 3 phase 60 cycle standard. 1 phase and / or 50 cycle motors are available. Electric motor types must be specified at time of ordering. Horsepower will vary depending on size of rollers.

Various models are available based on diameters and face widths of the rolls.

Information About the Machine:

One 3″ dust outlet and one 4″ dust outlet connection for a duct or flexible tube have been installed in the rear of the machine to attach to your ventilation system. It is recommended to use a gate valve at each outlet to adjust the air suction. If you choose not to use them, just cover the outlets. A plug (RC037P) is provided for the 3″ port.

Adjustment for finenesses is achieved by loosening both front nuts 57D and rotating handle 58-1. To see or measure the opening, lift up upper guard 37. It is very important that once the desired opening is set, to re-tighten the nuts, and close the upper guard.

Upon volume, material hardness and rolls opening, choke feeding may stall the machine. Therefore, in those circumstances it is recommended to slowly open the gate.

For machines with manual lubrication, one grease nipple is installed on each bearing housing. It is sufficient 2-3 squirts of grease every 80-100 hours. For machines with autolubrication, the machine bearings will be automatically lubricated. Ensure that the grease reservoir never becomes empty. Always check that the reservoir contains grease. For troubleshooting the autolubrication system, refer to the section for autolube – troubleshooting.

This machine has safety rectangular springs to prevent breakage of rolls, should steel or any other un-breakable material be dropped within the rolls. These springs have been pre-set at the factory, however if you notice that they open when you drop your media to be reduced they can be pre-loaded more by tightening the rear bolts 57C the desired amount.

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)

SKF – LGHB-2
Esso – Unirex EP2
Shell – Darina XLEP2
Chevron – Ultiplex grease EP2

Procedure for Removing/Reinstalling Rolls for Resurfacing/Replacing:

Remove the following parts in this sequence:

  1. Belts 23.
  2. 62-08 and 63-08 Side cover holders.
  3. 39D left side grease block.
  4. Parts 44-3 using the ½”NC tapped holes under the screws 51.
  5. Hammer out the spring pin 85A on adjustment plugs 85.
  6. Undo screws 57B-1 and 57B-2.
  7. Loosen set screw 39H and remove adjustment screws 57C.
  8. Remove rolls assembly (including drive pulley 30-1-08)
  9. Loosen the set screws on collars 42 on the opposite side of pulley.
  10. Remove bearing assemblies 39M and 39K from rolls to remove screws 48A-2-08.
  11. Use the threaded holes on parts 48B-2-08 to remove the rolls.

Follow procedure in reverse order for reassembly.
