How to Increase the Productivity of Jaw Crusher

With the large-scale use of jaw crushers, more and more people are concerned about the productivity of jaw crushers. How can we increase the productivity of jaw crushers?

With the large-scale use of jaw crushers, more and more people are concerned about the productivity of jaw crushers. How can we increase the productivity of jaw crushers? The following is an analysis by the engineers of the ZK CORP to improve the productivity of the jaw crusher.

The number of oscillating motions of the jaw crusher will increase and the productivity will increase accordingly. However, when the rotational speed exceeds a certain value, the frequency of the oscillating motion is too high, so that the crushed material is not completely discharged and the crushing cavity is easily clogged. Therefore, there is a critical value for the jaw crusher. The following assumptions can be used to understand and calculate the critical speed of the jaw crusher. The angle of engagement should have a certain range, others can be determined by force analysis. Assume that the mass of the spherical material trapped in the crushing chamber is negligible because the gravity generated is much smaller than the material crushing force. The action of the jaw plate on the material is perpendicular to the jaw plate at the contact point between the jaw and the material when swinging, the effective action angle stays the same, that is, the jaw moves away from the original position in parallel.

The broken material after breaking away from the quake is a trapezoidal section prism, and is free to fall by gravity.

To ensure that the jaw crusher has the important factors of high productivity, qualified products, low power consumption and stable long-term operation, it is the correct operation and reasonable and timely maintenance. Jaw crusher maintenance work, mainly focusing on lubrication, fastening, adjustment and cleaning and other aspects.

During the working process of the crusher, each friction surface should be lubricated in time to ensure the long-term normal operation of the crusher. Therefore, special attention must be paid to the lubrication of each lubrication area. Otherwise it will cause accidents or even major accidents. For the lubrication of the dynamic stern bearing and the thrust plate of the compound swing type crusher and the support pad, dry oil lubrication is generally used. In winter, if there is solidification of dry oil, 20% of automotive lubricants can be added for lubrication. The lubrication of all contact surfaces must be comprehensive and uniform. However, the degree of lubricating oil in the rolling bearing housing should not exceed 50-70% of its volume. According to the operating conditions, the oil can be filled once every 1-2 days. It is best to change the oil every quarter. At the same time, the bearings were thoroughly cleaned and inspected. Practice has proved that the ability to replace lubricants on schedule can extend the life of bearings and other parts.

Jaw crusher lubrication: We use the thin oil lubrication system is generally composed of oil pumps, filter coolers, oil pressure control valve, fuel tank, tubing, instrument indicator devices. When the oil pressure is too high or the oil flow rate is too high, adjustment can be made through the oil pressure adjustment valve. In the normal lubrication process, the oil flow rate must be appropriate. The return oil temperature of the dilute oil lubrication system cannot be higher than 600 degrees, and the normal temperature in the oil tank should be controlled at 35-50°C. When the oil temperature is too high, water cooling measures should be taken. The water pressure should be less than 0.5 atmospheres of oil pressure. When the pressure difference between the front and rear of the oil filter exceeds 0.40 atmosphere, the filter should be cleaned. The oil lubricated lubricating oil should be replaced every 3-6 months under normal operating conditions. At the same time, the fuel tank and other related lubrication components and parts must be thoroughly cleaned with kerosene to ensure the smoothness of the entire lubrication system and the oil quality is clean. For parts that are regularly lubricated with manual lubrication, more attention should be paid to timely, appropriate, and accurate lubrication.

It is necessary to increase the productivity of the jaw crusher, but to increase the service life of the jaw crusher within a reasonable range, the machine itself cannot be impaired in order to increase productivity.
