Jaw Crusher
Jaw crusher is one of main industrial equipment in stone crushing process or rock crushing plants, is can reach the crushing ratio of 4-6 and the shape of final product is even. And the pressure resistance strength of jaw crusher is under 200Mpa, suitable for primary crush.
Jaw crusher has been widely applied in mining, metallurgical, construction, road and railway building, water conservancy and chemistry etc. For example, in rock quarry plants, the most widely used stone crusher machine maybe the jaw crusher. Jaw crusher is the key crushing equipment in stone crushing plant, rock grinding plant, quarry crushing plant and so on.
Small Jaw Crusher
Small jaw crusher is a jaw crusher with small volume, small size of feed inlet, small capacity, little weight etc. Small jaw crusher is used widely in small mining industry or small quarry plants for its low price and high quality. For example, SBM can supply you samll jaw crusher such as jaw crusher PE150×250, PE250×400 etc. PE150×250 means its feed inlet width is 150 and height is 250.
Used Jaw Crusher
Jaw crusher machine uses motor as its power. Through the motor's wheels, the eccentric shaft is driven by the triangle belt and slot wheel to make the movable jaw plate move by a regulated track. Therefore, the materials in the crushing cavity composed of fixed jaw plate, movable jaw plate and side-lee board can be crushed and discharged through the discharging opening.
Heavy jaw crusher or large capacity jaw crusher is the latest developed jaw crusher for huge mining industry. According to our experience, heavy jaw crusher can meet the requirements for rapid expansion of mining business. We can supply you many models of heavy duty jaw crusher such as EX250×1200. Besides this jaw crusher, we can manufacture whatever model jaw crusher you want.
Jaw Crusher Operation
Jaw crusher machine uses motor as its power. Through the motor's wheels, the eccentric shaft is driven by the triangle belt and slot wheel to make the movable jaw plate move by a regulated track. Therefore, the materials in the crushing cavity composed of fixed jaw plate, movable jaw plate and side-lee board can be crushed and discharged through the discharging opening.
Jaw Crusher Maintenance
1. Jaw crusher should be greased and oiled regularly; this should be done prior to each use.
2. Check jaws for cleanliness and clean them if needed. Loosen the wing nuts and remove the front shield, then loosen the hopper wing nuts (located below the hopper on the left and right of the machine) and move it up and back so that the jaw cam lock is exposed. Lift the cam lock up to release the stationary jaw so that it may be lifted straight out. If it is jammed, the cam lock may be freed by tapping lightly with a mallet or ball-peen hammer.
3. Adjustment of jaw spacing: Turn the circuit breaker (located in the breaker box) to the "ON" position. While the crusher is empty, start the machine and allow it to come up to full speed. The machine must be adjusted while running. Loosen the square-head bolt (left). This will allow the hand knob (or right) to turn.
4. Once the jaws have been set, place a clean sample collection tray under the machine to collect the crushed sample. If concerned about contamination of sample material by skin oils and/or perspiration, wear clean, powder free latex (or equivalent) gloves while handling the samples. When sample volumes permit, it is recommended that the machine be "pre-contaminated". This is done by processing a small amount of the sample to be crushed (thus coating the inner workings of the machine) and discarding the resultant product. This reduces the amount of sample contamination from the machine.
5. When the crushing process is complete, remove the sample collection tray and transfer its contents to a clean container.
6. Prior to next use, clean the crusher and collection tray(s) as described previously. When done for the day, make sure the lab is cleaner than it was when you started, that the breaker to the crusher is turned off, lights are out, and door closed and locked.
