The roll crusher has been recognized by people for several years. Its working performance is very stable. It is because of its good work performance that it has won a very good development opportunity for roll crusher manufacturers due to the roll crusher. There are so many types of roll mills for customers that are suitable for their own roll mills. Huashengming Heavy Industry Co., Ltd. is a roll crusher with many years of production experience. As a crusher manufacturer, it provides several methods for customers to understand clearly what kind of roll crusher is suitable for themselves.
What are the major concerns regarding the maintenance and repair of roll mills?
1. Crusher The main and auxiliary transmission gearboxes are lubricated with gear oil. The oil in the cabinet should be replaced in summer and winter.
2. When changing the strength, particle size or crushing ratio of crusher materials, the nitrogen pressure of the buffer tank should be reset. The size of the pressure is moderate to meet the need of the crushing roller pressing force. Excessive compression force will promote accelerated wear and increased power consumption. Too small compressive force will increase the number of broken particles and cause the active crushing roller to exhibit frequent vibration. The buffer cylinder nitrogen pressure range is 1.5-4 MPa.
3. After the crusher is overhauled, when re-assembling the upper crusher roller and the clam shell coupling, the tightening torque must be strictly controlled for the round nut and the coupling bolt. When tightening the clamp coupling bolts, attention must be paid to the sequence. The diagonal bolts should be tightened first, and then the intermediate bolts should be tightened. Also note that the gaps on both sides of the sub-area of ​​the coupling should be uniform.
4. Maintenance and repair If you need to open the cover of the main and auxiliary transmission gearbox, you must replace the rubber seal before reinstalling and evenly apply a layer of sealant on the static sealing surface to prevent the sealing surface from seeping oil and leaking oil. .
5. The crusher upper and lower crusher roller translational linkage device bearing grease lubrication, design requirements using 2 or 3 calcium-based grease. In normal production, the oil cup lid should be tightened for one week to inject grease.
6. No matter what way to feed the crusher, a reliable rust removal device must be installed to prevent other debris from entering the crusher.
7. Check the oil level in the main and auxiliary gearboxes to ensure adequate oil supply.
8. The crusher must be started without load. Before starting, the crusher must check and remove the retained materials. Check the oil level in the main and auxiliary gearboxes to ensure adequate oil supply.
9. Start the crusher to normal speed and begin feeding without exception.
10. If the crusher is deactivated for a long time or it is started for the first time, manpower should be used to rotate the large pulley for 2-3 weeks in advance to make sure that the machine can run freely. Then the motor is “jogged†several times. When the direction of rotation of the motor is correct, The crusher is officially started.
11. Regularly check whether the crusher product granularity meets the requirements. If necessary, you can readjust the spacing of the crushing rollers.
12. It is necessary to stop the feeding in advance during normal shutdown. All materials in standby can be stopped after the crusher is removed.
