1. The bearings in the double toothed roll crusher bear all the load of the machine and the favorable lubrication influences much to the life and efficiency of the bearings’ service.
The lubricating oil must be clean and kept in good seal condition. The main oiling places are the gearbox, roller bearing, all chains, movable bearing, and movable surface.
2. The degree of wear of the roller skin has a great influence on the working efficiency of the double toothed roll crusher. Only when the roller skin is in good condition can a higher production capacity be obtained.
The material distribution should be uniform, otherwise the roller skin is easy to wear, and there will be ring-shaped grooves on the surface of the roller, and consequently, the particle size of the crushed product is uneven.
The length of the feeder should be equal to the length of the roller to ensure uniform feeding along the roller. At the same time, in order to continuously feed ore, the rotation speed of the feeder should be faster than the rotation speed of the roller, about 1-3 times faster.
During the operation of the crusher, attention should also be paid to the size of the ore block feeding. If the ore block is too large, it will produce severe impact and the roller skin will be seriously worn.
3. A reliable iron removal device must be provided to prevent other sundries from entering the crusher. Check the oil level in the main and auxiliary gearboxes to ensure sufficient oil supply.
4.The double toothed roll crusher must be started without load, and the remaining materials in it must be checked and removed before starting.
If the double-toothed roller crusher is not used for a long time or is started for the first time, the large pulley should be rotated 2-3 times before starting the motor. Only after the motor rotates in the correct direction can the double-toothed roller crusher be officially started.
5. Dust and other objects on the surface of the chassis on which the movable system is put on should be removed to avoid the movable bearing cannot be moved flexibly on the underframe when the machine encounters non-crushed materials, thus causing serious accidents.
6. Each roller of the double toothed roll crusher is driven by a single motor. Since materials change their property, they make the roller move from left to right. In this case, it’s necessary for us to raise the height of the gear tooth in order to prevent the tooth from separating from the roller.
7. After the double toothed roll crusher has been running for a long time, due to the large wear of the roller surface, the product particle size will be too fine. At this time, attention should be paid to adjusting the ore discharge port or overhauling the equipment.
8. The corrosive also has effects on double toothed roll crusher lifetime. Because rain, snow and air pollution cause corrosion to double toothed roller crushers, users should take effective measures to reduce their impact.
9. Pay attention to the oil temperature of the bearing. Once the temperature is too high, it must be stopped immediately for inspection and correction. If there is a strong impact sound when the gear is rotating, it is also necessary to stop the machine for inspection and correction.
10. When it is necessary to change the crushing ratio and move the roller, the roller must be moved in parallel to prevent the roller from skewing, otherwise it will cause rapid and uneven wear of the roller skin, and in severe cases, it will cause accidents.
11. The gearbox must be replaced with new oil after one month of initial use, cleaned with kerosene, and filled with new oil. Under normal production condit
