In the current state of continuous investment in the development of mining equipment, different types of cement plant special crushers produced by Shengming Heavy Industry Co., Ltd. Whether the work efficiency or the crushing principle is the most worthwhile choice for customers in the industry material crushing. For the cement plate of the special crusher in the cement plant, it is in direct contact with the material during the crushing process of the special crusher in the cement plant. Because it is squeezed and ground, it often fails quickly. It is one of the main wearing parts of the crusher in the cement plant. . According to the survey, the average service life of a tooth plate is about 3 months, that is, each crusher uses 4 tooth plates for one year. A crusher with a large crushing capacity in a cement plant walks in different industries through its own crushing technology and principle in the creation and development process of the construction industry, so its life and maintenance are closely related.
Cement Plant Crusher Four Seasons Maintenance Points:
1. Check the oil level in the main and auxiliary gearboxes to ensure adequate oil supply.
2. The crusher must be started with no load. Before starting, the crusher must be checked and cleared of retained materials.
3. Start the crusher to normal speed and start feeding without exception.
4. No matter what way to feed the crusher, a reliable rust removal device must be provided to prevent other debris from entering the crusher.
5. Be sure to stop the feeding in advance during normal shutdown. All materials in standby can be stopped after the crusher is removed.
6. 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 confirm that the machine is operating freely. Then the motor is “jogged†several times. When the direction of rotation of the motor is correct, The crusher is officially started.
7. Crusher main and auxiliary gearboxes are lubricated with gear oil, and the oil in the cabinet should be replaced in summer and winter.
8. Regularly check whether the crusher product granularity meets the requirements. If necessary, you can readjust the spacing of the crushing rollers.
9. 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.
10. Maintenance and repair If you need to open the cover of the main and auxiliary transmission gear boxes, you must replace the rubber seal before reinstalling and evenly apply a layer of sealant on the stationary sealing surface to prevent oil leakage and oil leakage from the sealing surface. .
11. Crusher upper and lower crusher rollers The bearings of the translational linkage device are lubricated with grease. The design requires the use of No. 2 or No. 3 calcium-based grease. In normal production, the oil cup lid should be tightened for one week to inject grease.
12. 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.
Each of the special crushers of Huashengming Heavy Industry Cement Factory is designed for the immediate and future transformation of our urban life and created continuously by the manufacturers. Their various types of crushing capacity are used during the use of these machines. It is an ideal choice for customers. The special crushers in Huashengming Heavy Industry Cement Factory are scattered all over the city. No matter what kind of particles can be directly broken by a roller crusher, the efficiency of production is always very high. 13838274368 18737170196
