Roll crusher Notes
1) To strengthen the work for iron ore. Non-broken (solder first-class objects) fall between the double roll crusher can damage, resulting in parking accident. So before the crusher should be installed in addition to iron.
2) viscous material easy to plug the broken space processing clogging fault should stop treatment, it can not be stabbed in the mine operation.
3) When the material handling chunk containing more, pay attention to large pieces of ore easily squeezed out from the crushing space, to prevent injury or damage to the device.
4) double roll crusher operation after a long time, due to the large wear of the roll surface can cause the product size too small, then pay attention to adjust the port of discharge or equipment maintenance.
5) to strengthen the inspection of double roll crusher equipment for lubrication equipment to refuel on time and keep good equipment lubrication.
Installation of the roll crusher, commissioning and commissioning
Mounting and adjustment of the machine:
Foundation plans to use the reference unit, the design basis for the construction drawings appended to this specification, the machine will be installed firmly fixed on the basis of specially designed, in order to better withstand the force of the machine at work are produced, sleepers can be placed in the underframe wood so that the entire machine and wooden sleepers fit, and stay out of the discharge location.
The machine is supplied with a complete assembly forms, subject to careful examination during storage during transport Chinese a long time, the machine without injury, the sliding portion and the lubricating rust, whether complete machine can be carried out to determine the non-destructive installation, machine installation , and then identify the level, then press drawings for installation of transmission parts, drive belts should be adjusted to the appropriate location on the elastic pressure of the spring shall be transferred to the appropriate position before.
After all the end of the installation but also strictly check each bolt fastening portion without loosening.
The commissioning of the machine:
Before the machine is installed, formally put into production, the need for commissioning.
1. lost motion transfer test:
Machines in use of the site shall be not less than 2 hours of continuous idling test, dynamic change when bearing temperature rise should not exceed 30 ℃, the maximum temperature shall not exceed the long 40 ℃, part of the sprocket, gear, pulley triangle and roll and so on should be rotated smooth, no unusual noise, a collision between the rollers can not.
2. load test:
Empty running test to achieve a good basis, can only perform load operation test, load test no less than eight hours of continuous operation.
Determination of the actual Liaoduo and production to meet the requirements, and to ensure that the bearing temperature rise should not exceed 35 ℃, crusher should be smooth, there should be more severe vibration, each fastener should be solid. All lubrication points must be filled with grease. Should be good sealing, no leakage.
When the operation is found yield or size does not meet the requirements, the use of active device to adjust the rear end of the adjusting bolt, such as found in current ripple unstable during operation, you should check whether the feed size to meet the requirements, can be put into normal after the load test production use.
