Reasons that affect the quality of finished products during the production of sand and gravel aggregates

Sand and gravel aggregates are commonly used materials in the construction field, and their quality directly affects the safety and quality of construction projects. In the production process of sand and gravel aggregates, there are many factors that will affect the quality of the finished products. The following are some of the main reasons:

1. Poor quality of raw materials

Raw materials are the basis of sand and gravel aggregates, and their quality directly affects the quality of finished products. If the raw materials contain too much impurities, dust or too high water content, the strength and stability of the finished products will be reduced, affecting the service life of the building.

2. Improper crushing equipment

Crushing equipment plays a key role in the production of sand and gravel aggregates, but if the equipment is improperly selected or improperly operated, the quality of the finished products will be reduced. For example, unreasonable setting parameters of the crusher, inadequate maintenance or severe wear will affect the particle size and shape of the finished products.

3. Unreasonable screening process

Screening is an important link in the production process of sand and gravel aggregates. Its purpose is to separate qualified finished products according to certain specifications. If the screening equipment is improperly selected or the screening process is unreasonable, the finished product will contain too many fine particles or coarse particles, affecting the working performance and strength of the concrete.
