INSTALLATION

Home-Terminator Laboratory Crusher Stand Installation:

For Jaw Crusher when supplied with a 3”X4” Mounting stand:

  1. Before attaching 3”X 4” Jaw crusher assembly plate, ensure that stand site is secure. Stand should be set on flat even ground. Make sure each leg of stand is flush to ground surface and capable of supporting weight. Crusher is designed to operate on level surface, any slopes that cause crusher to sit at an angle will effect operating effectiveness. Warning: When Placing stand on soft materials, make sure all legs will remain equally supportive to avoid topple risk, which could result in damage to crusher, and operator.
  2. Carefully place 3”X 4” Jaw Crusher assembly plate carefully atop stand so that Jaw Crusher dispensary, and motor mount adjustments properly line up.
  3. Firmly Bolt down Jaw Crusher assembly to stand with all four corner mounting points.
  4. Check level and stand surface intermittently during operation to ensure stability and optimal performance.

For all other Stand mountings:

  1. Before attaching 3”X 4” Jaw crusher assembly plate, ensure that stand site is secure. Stand should be set on flat even ground. Ensure stand specifications are strong enough to support total weight of Crusher Mount. Make sure each leg of stand is flush to ground surface and capable of supporting weight. Crusher is designed to operate on level surface, any slopes that cause crusher to sit at an angle will effect operating effectiveness. Warning: When Placing stand on soft materials, make sure all legs will remain equally supportive to avoid topple risk, which could result in damage to crusher, and operator.
  2. Carefully place 3”X 4” Crusher mount atop stand. Ensure that nothing inhibits Crusher dispensary opening from underneath and that there is room for a bucket or collection hopper. Consider motor mount adjustment points and accessibility for future use.
  3. Firmly Bolt down Jaw crusher assembly with all four corner mounting points.
  4. Check level and stand surface intermittently during operation to ensure stability and optimal performance.

FEEDING INSTRUCTIONS128-parker-crusher-for-sale

*NEVER OPERATE ROCK CRUSHER WITHOUT SAFETY GUARDS PROPERLY IN PLACE OVER PULLEYS AND FLY WHEEL*

Once properly mounted to a stand, and with safety guards in place your Rock Crusher is ready to begin crushing rock. Adhering to the following steps will yield the best results:

  1. Before turning on Rock Crusher, make sure jaws are free of debris.
  2. Plate collecting bucket or trough underneath dispensary area of rock crusher to catch particles.
  3. When Rock Crusher is running, feed rocks with a maximum size of 1 ½”X 2” into top of Crusher. Always keep the lid closed between feedings to protect against flying particles, and dust.
  4. Do not overfeed Rock Crusher, for best results allow only half the jaw area to be filled with rock at one time. Do not fill crusher right up to top of the jaws, this puts too much pressure on jaws and can damage bearings.
  5. Speed and Particle size are a factor of how the lower jaw width is set. Read how to adjust dispensary particle size in order to make changes. Smaller Particle size the longer it will take the Jaw Crusher to work through rock, the Larger the particle size setting, the faster the jaw crusher can work through rock.

Other tips:

  • Rock Crusher should be used outside, or, in properly ventilated area.
  • Rock Crusher is designed to be used by adults. Parental supervision is needed for operators who are under the age of maturity.
    • Do not engage in horseplay while operating the rock crusher.
    • Always pay attention while operating the rock crusher.
    • Do not operate rock crusher if you are sick, fatigued or is taking medications that cause drowsiness.
    • Only one person should feed the rock crusher at any one time.
    • Keep the floor around the rock crusher machine clean, dry and free from trip hazards. Do not allow chips to accumulate.
    • Users of rock crusher shall be aware of the location of first aid kits, fire exits, fire extinguishers, fire alarms, eye washes, deluge showers, emergency telephones and other safety related facilities.

JAW ADJUSTMENTS

*MAKE SURE JAW CRUSHER IS DISCONNECTED FROM POWER SOURCE BEFORE DOING ANY SERVICING OR ADJUSTMENTS*

Adjusting Jaws allows you change the ways the Home-Terminator Laboratory Crusher performs for different rocks and output requirements.

Adjusting Dispensary Particle Size can be done by adjusting the HEX nut on the back of the crusher between the crusher and engine.

To DECREASE particle size: Use ¾”wrench to turn hex nut clockwise (Towards Pulley). Be aware of centric bearing position when measuring jaw opening. Jaws should never run in contact with one another. Make sure to loosen off Spring Rod fly nut, by adjusting counter clockwise. Tightening jaw width without loosening spring rod will cause excessive wear to Spring Rod and toggle plate. Spring Rod adjusting Fly Nut should be approximately ½” from end of adjuster when jaw plates are at maximum tightness

To INCREASE particle size: Use ¾” wrench to turn hex nut counter clockwise (Towards Fly Wheel). Be aware of centric bearing position when measuring jaw opening. Make sure to tighten Spring Rod fly nut by adjusting clockwise so that there is always pressure to return the jaw. Opening jaw width without tightening spring rod can cause toggle plate to slip, and reduce effectiveness of Jaw Crusher.

Jaw Plate Swap and Rotation. Get the most life and performance out of your Jaw Crusher and Jaw Plates, by rotating plates, and changing out for fresh plates when needed.

ROTATION: The Jaws plates are made from high manganese steel and wear is very gradual, however you will want to rotate jaw pieces after extended use which causes the lower jaw areas to flatten. This is done in 3 easy steps:

  1. Remove the 4 bolts and bracket at the mouth of feeder which hold jaw plates in position.
  2. Slide out jaw plates. Turn plates around so bottom is top, and top is bottom, and place back in same side. (Longer Jaw piece on adjustable side, Shorter Jaw on stationary side) Make sure to clean out any dust or debris which has fallen on lower jaw brackets, which could cause remounting problems.
  3. Ensure flushness of plates, then reinstall jaw brackets with 4 bolts.

Repeat process as needed throughout life of jaw plates to maximize usefulness.

SWAP: When you have used your existing jaw plates to the end of their effective life, swap them out for a new set. 3”X 4” Home-Terminator Laboratory Crusher is designed to use engineered Jaw Plates Only. To ensure the rock crusher continues to perform correctly only use Abel Equipment approved parts. Steps to swap Jaws:

  1. Remove the 4 bolts and bracket at the mouth of feeder which hold jaw plates in position.
  2. Slide out old Jaw plates. Make sure to clean out any dust or debris which has fallen on lower jaw brackets, which could cause remounting problems.
  3. Slide new plates into place. Make sure that the longer back plate is on the back side and that the shorter stationary plate is on the front stationary side. Make sure that when looking into Jaw Crusher, jaw teeth interlock correctly.
  4. Ensure flushness of plates, and reinstall jaw brackets with 4 bolts.

MAINTENANCE

For optimal performance it is important your Rock Crusher Unit receives regular maintenance.

Rock Crusher:

Regular greasing is important to get the maximum performance and life out of your Rock Crusher. We recommend using a heavy duty #2 grease. Greasing Instructions:

  1. The jaw must be greased once every eight (8) hours of operation on the two nipples of the movable jaw above toggle and below motor base.
  2. Grease the two (2) side bearing nipples located on either side of the crusher. The nipples have been extended up to make servicing easier. This should also be done every eight (8) hours of operation.
  3. Don’t grease motor. This is a ball bearing motor and only requires grease after years of operation.
  4. The toggle should be periodically removed, cleaned and lubricated with a high temperature wheel bearing or open gear lubricant.
  5. The adjusting screw (grease nipple located on the Hex head adjusting nut) and the adjusting block assembly (grease nipple located below the maintenance access port) should be thoroughly lubricated monthly.
