Sand - making machine is a common facility in sand - stone production line. Shanghai ZENITH
sand making machine is also known as impact crusher, because its crushing particle size is small (up to 20 mesh). So it is called sand making machine.
Common failure of sand making machine and treatment measures. Sand making machine is suitable for the soft or hard and hard materials in the crushing, plastic, are widely used in all kinds of ores, cement, refractories, aluminum every soil clinker, carborundum, glass raw materials, mechanisms, build stone for gold slag, especially for silicon carbide, corundum, sintered bauxite, the sand jof hard, hard and abrasive wear resistance materials is higher than other types of crusher production effect. This paper will introduce common failures of sand making machine and treatment measures:
1, sand machine bearing load is too large: check the size of the load. Under the correct load conditions, control to a reasonable range.
Second, sand machine bearing torque load of foreign invasion, inflow: improved anti-rust sealing device, downtime. Improved surface finish of paired rolling parts. Showing the dark side, the dark surface has a slight wear depth of 5-10M with microcracks and small openings where fractures occur within a wide range from the surface to the inside. Improved sealing device.
Improper lubricants: use appropriate viscosity lubricants to improve lubrication. Poor surface finish of
sand making machine bearing paired rolling parts. Foreign matter gets into the lubricant. Choose the right lubricant.
Bearing clearance is not suitable. Bearing housing is poor precision, bearing housing rigidity, is not uniform: check the accuracy of the shaft and bearing housing. Check the gap.
Check the accuracy of bearing and bearing seat for bearing shaft rusting, erosion, wear and indentation. Ball press bearing load inner ring rotation, outer ring raceway surface or rolling decent rolling fatigue appears flake. A minor burn to a part of the sliding surface resulting from a so-called stuck injury that aggregating the damage from a surface injury. Poor surface roughness caused by lubricating oil. Stripping lubricants is inappropriate, improving lubricants and lubrication methods.
