The sand making machine is an important piece of equipment in the production of modern building materials, used to process stone into artificial sand that meets standards. However, during actual operation, due to various factors, this equipment may experience faults of varying degrees, affecting production efficiency and product quality. Understanding the causes of these faults and taking appropriate preventive measures is of great significance for improving the stability of the equipment and extending its service life.
Causes of Sand Making Machine Faults
Mechanical Component Wear
Core components of the equipment, such as the impeller and liners, gradually wear down over time under high-speed operation, especially when processing harder materials. This wear not only reduces sand-making efficiency but can also cause abnormal vibrations and noise in the equipment. Regular inspection and replacement of worn parts can effectively prevent this issue from occurring.
Bearing Overheating
As a key component supporting the rotation of the main shaft, the bearing’s working condition directly affects the overall operational stability of the machine. If lubrication is inadequate or if the quality of the selected lubricating oil is poor, it can lead to excessively high bearing temperatures, and in severe cases, even result in seizure. Therefore, maintaining good lubrication conditions and selecting suitable lubricants are effective means of preventing bearing overheating.
Overloading Operation
When the feed rate exceeds the design capacity of the equipment or the material contains large chunks, it can easily cause the sand making machine to overload, leading to motor overheating, increased current, and other issues. To avoid this situation, the feed rate should be strictly controlled according to the requirements specified in the equipment manual, and a screening device should be installed at the feed opening to remove large pieces of material.
Electrical System Faults
The electrical control system is responsible for coordinating the work of all parts. Once faults such as short circuits or poor contact occur, they will directly result in the equipment failing to start or operate normally. Regular inspections of the electrical wiring to promptly identify and eliminate potential hazards form the basis for ensuring the safe operation of the sand making machine.
