Jaw crusher units are factory assembled into the supply. Users receive the broken machine, should be carefully examined in order to identify and exclude potential transportation problems.
Machine installation should note the following.
(1) The jaw crusher vibration of a larger work, the machine should be installed in the concrete foundation, in order to reduce vibration, noise, and the nearby building, structures based on the impact crusher and the concrete foundation in the middle of the hardwood plate pad , rubber band or other damping materials.
(2) the basis of discharge slot to lay a layer of metal plates, and has enough tilt angle (depending on the flow of materials should be determined not less than 50.), So as not to hinder the smooth discharge of the product after crushing.
(3) nesting population size of the particle size should be required to adjust. Adjustment, should release the T-bolts and tension springs. Used to open the top adjustment bolt from the top seat, insert, or removing the appropriate thickness of the gasket, and then returned to play the top bolts, adjust the seat the role of gravity in the moving jaw under the ear close to the seat frame, while pressure washer set rope together. Since then, adjust the spring preload to ensure that the machines work, the thrust plate and thrust plate pad close. But the pre-stress should not be too large, does not occur as long as the mechanical percussion, the last lock seat adjustment.
Second, the operation of jaw crusher
1. No-load test
(1) 2 hours continuous operation, the bearing temperature must not exceed 30 ℃.
(2) All fasteners should be firm, not loosening.
(3) flywheel, pulley smooth operation.
(4) All components of friction without abrasion, debris and grinding out the phenomenon, no unusual sound.
(5) The discharge opening of the adjusting device should be able to ensure that the adjustment range of discharge opening.
2. Load test
(1) crusher or may not have a significant cyclical impact crash.
(2) The maximum feed size should meet the design requirements.
(3) continuous operation 8h, bearing temperature must not exceed 30 ℃.
(4) crusher capacity and product size should meet the design requirements.
(5) adjust the seat and seat rack ear was not significantly rocky ledge.
3. Preparations before use
(1) Carefully check the bearing lubrication is good, the thrust plate connections have enough grease.
(2) carefully check all fasteners are tightened.
(3) Carefully check the belt is good. If there is breakage, should be replaced, when the drive belt or pulley when there is oil, oil rag and wipe applications.
(4) Check the protection device is good. Found that insecurity, should be immediately removed.
(5) Check whether the ore crushing cavity or debris. If ore or debris, you must clean up to ensure that the crusher cavity start.
(6) Check whether the return from the top bolts, washers group is pressed, T-shaped bolts are tightened.
4. The start of jaw crushers
(1) The inspection proved that the various parts of the machine conditions are normal, before starting.
(2) The jaw crusher is only allowed in case of no-load starting.
(3) before starting to use the tone or signal prior warning.
(4) starts, if there is not normal, they should stop immediately. Not to be identified and excluded from normal circumstances, be re-starting the crusher.
