Troubleshooting Common Faults of Manufactured Sand Production Line

Long-term continuous operation of the aggregate crushing plant often leads to malfunctions including material blockage, unqualified discharge particle size and abnormal equipment noise, which directly reduce production efficiency and finished product quality. Timely inspection and rapid troubleshooting are essential to ensure stable operation of the aggregate crushing plant. This article sorts out the root causes and practical solutions for these three frequent faults that commonly occur on the aggregate crushing plant.

● Cause

Material blockage ranks the most frequent breakdown in a manufactured sand production line. Causes fall into material and equipment aspects. Excessive moisture and impurities in raw materials, overfast feeding speed or oversized incoming material size will lead to material accumulation and blockage inside the crushing chamber, screen mesh and discharge outlet of the manufactured sand production line. Besides, low rotating speed, loose conveyor belts and excessively narrow discharge opening will also result in blockage during the operation of the manufactured sand production line.

◎ Solutions

Shut down the sand making plant immediately to clear accumulated materials on site. Strictly control feeding specifications and maintain even feeding rate. Clean the crushing cavity and screening equipment on a regular basis, adjust the rotating speed and discharge opening dimension. Preprocess raw materials in humid weather to prevent material adhesion and blockage for stable aggregate crushing plant operation.

● Cause

Unqualified discharge particle size is mainly manifested as uneven fineness of finished sand and excessive stone powder content in a sand making plant. It is mostly caused by severe wear of wearing parts such as liner plates and impact heads of the crusher, which weakens the crushing effect of the sand making plant. Meanwhile, damaged, loose or clogged screen meshes of screening equipment fail to classify materials effectively, also resulting in substandard particle size for the sand making plant.

◎ Solutions

Inspect and replace worn vulnerable parts regularly to guarantee crushing precision. Repair or replace broken screen meshes promptly and clear blocked materials on screens. Fine-tune equipment parameters according to production requirements so that finished grain size meets specified standards.

● Cause

Abnormal operating noise is generally attributed to mechanical failures and improper installation of the aggregate processing plant. Worn and aging bearings and gears with insufficient lubrication, loose bolts and dislocated components will generate strange noise during the operation of the aggregate processing plant. In addition, hard foreign objects like iron blocks entering the crushing chamber will cause loud impact noise and affect the stability of the aggregate processing plant.

◎ Solutions

Stop the aggregate processing plant for a full inspection of components, fasten loose bolts and replace worn spare parts. Perform periodic lubrication to keep the manufactured sand production line running smoothly. Screen raw materials before feeding to keep hard impurities out and avoid such faults from the source for the aggregate shaping and sand making plant. Standardized daily maintenance can effectively reduce failure rates and maximize the service life of the aggregate shaping and sand making plant, ensuring long-term and high-efficiency operation of theaggregate shaping and sand making plant.
