Why does the VSI rotor need to be tested for dynamic balance?
The rotor of the sand making machine needs to be tested for dynamic balancing. The reason is that when the rotor rotates around its axis, centrifugal force is generated due to the uneven distribution of mass relative to the axis. This unbalanced centrifugal force will cause vibration on the rotor bearing, generate noise and accelerate bearing wear, seriously affecting the performance and life of the sand making machine. In order to solve this problem, it is necessar

How to solve the problem of large amount of powder discharge from crusher?
To solve the problem of large amounts of powder discharge, the following measures can be taken: 1. Choose a suitable crusher Choose a suitable crusher type and model according to the actual material conditions and production requirements. If the powder quantity requirement is high, a cone crusher can be selected; if the powder quantity requirement is low, an impact crusher can be selected. 2. Adjust crusher parameters Ad
What are the methods to solve the problem of oil temperature rise in cone crusher?
1. Clean up oil pollution: Regularly change the oil, clean the oil filter and oil cooler to avoid oil pollution. At the same time, keep the oil clean and avoid impurities, moisture, dust, etc. from entering the oil. 2. Check the lubricating oil supply: Ensure that the lubricating oil supply is sufficient. Check the lubricating oil level and replenish the lubricating oil regularly. 3. Optimize the design and layout of the cooling system: Rat
What causes the oil temperature of the cone crusher to rise?
1. Oil contamination: Impurities, moisture, dust, etc. in the oil will cause the performance of the oil to decline, the viscosity to decrease, and the resistance to decrease, thereby accelerating the oil circulation speed, reducing the heat dissipation capacity, and causing the oil temperature to rise. 2. Insufficient lubricating oil: If the supply of lubricating oil is insufficient, the heat generated by friction cannot be e
What is the reason for multi cylinder hydraulic cone breaking and pressure relief?
Multi cylinder cone crusher is a typical crushing equipment for medium and fine crushing of hard materials. During operation, the moving cone rotates and swings along the inner surface. Near the fixed cone, the material is crushed by the compression and bending of the moving cone. When deviating from the moving cone, the crushed material falls from the bottom of the cone due to gravity, and the entire crushing and unloading process cont
What is the hydraulic pressure relief treatment method for cone press?
1. Timely inspect hydraulic pipelines and joints, confirm the location of oil leakage points, and then carry out repairs and replacements. 2. Check the hydraulic oil tank, return oil filter screen, hydraulic oil filter element and other components to see if there are any damage, filter element blockage or insufficient hydraulic oil volume problems, and deal with them in a

Crushing section of the crusher
Each time solid waste passes through a crusher or grinder is called a crushing stage. For different crushing ratio requirements, the crushing stages are also different. If the required crushing ratio is not large, one stage of crushing is sufficient. However, for some solid waste sorting processes, such as flotation and magnetic separation, since the particle size of the feed is required to be very fine and the crushing ratio is very large, sever
The ratio of the raw material particle size to the finished material particle size after crushing is referred to as the crushing ratio, which directly affects the energy consumption and processing capacity of the crusher and is a key factor in measuring the crushing effect of the crusher.
