What to do if there is a problem with the sand making machine in the sand making production line?

The sand making machine is a crucial piece of equipment in a sand production line. Its powerful crushing and shaping capabilities enable it to process materials of varying hardness, such as ores, cement, and refractory materials. It is particularly suitable for high-hardness, abrasion-resistant materials, such as silicon carbide, corundum, and sintered bauxite, with output and efficiency far exceeding other types of crushers. This article will introduce common sand making machine malfunctions and troubleshooting measures:

Sand Making Equipment Knowledge Consultation

I. Excessive Load on Sand Making Machine Bearings: Check the load magnitude. Under proper load conditions, control it within a reasonable range.

II. External Intrusion of Torque Load into Sand Making Machine Bearings: Improve rust prevention sealing devices and reduce downtime. Improve the surface finish of mating rolling parts. Darkening of the surface, with slight wear, micro-cracks 5-10 μm deep, and small openings appearing on the mounting surface, extending over a wide range inwards. Improve the sealing device.

III. Improper Lubricant: Use lubricating oil of appropriate viscosity to improve lubrication. Poor surface finish of mating rolling parts in sand making machine bearings. Foreign matter has entered the lubricant. Select a suitable lubricant.

IV. The bearing clearance is inappropriate. The bearing housing has poor precision, and the rigidity of the bearing box is uneven: Check the precision of the shaft and bearing housing. Check the clearance.

V. For sand making machine bearings, check for rust, corrosion, wear, and indentation points on the shaft and bearing housing precision. For ball press bearings, under load, the inner ring rotates, and rolling fatigue on the outer ring raceway surface or rolling element surface manifests as scaly peeling. So-called jamming damage results in minor burning of the sliding surface, summarizing surface damage. Poor surface roughness caused by lubricating oil. Inappropriate lubricant stripping; improve the lubricant and lubrication method.
