Quality appraisal of sand and gravel aggregate production line

sand and gravel production line is a special production line equipment for producing construction sand and stone. It saves 50% energy than traditional sand making machines. It can make rocks, sand, river pebbles and other materials into various particle sizes that meet the requirements of construction sand. The sand produced by the sand and gravel production line has uniform particle size and high compressive strength. It is far more in line with construction requirements than the sand produced by natural sand and ordinary hammer sand making machines, and can improve the quality of construction.
In the case of sand and gravel aggregate production line quality appraisal, Zhongke Testing can provide sand and gravel aggregate production line quality appraisal services.

sand and gravel aggregate production line is mainly composed of feeder, crusher, vibrating screen, conveyor and other equipment, connected by a belt conveyor in the middle.
sand and gravel aggregate production line performance test includes: production line output test, production line energy consumption test, product quality test, production line noise test, and dust emission concentration test.

quality product dispute situation:
According to the situation reported by the entrusting party and the information provided, the entrusting party signed an "Order Order" with a certain manufacturer (hereinafter referred to as the supplier) to purchase a set of "Sand and Gravel Aggregate Production Line" involved for processing stone. During processing, the client discovered that the screening equipment of the sand and gravel aggregate production line had low screening efficiency, could not screen thoroughly, could not separate cleanly, and had frequent failures, resulting in uneven quality of sand and gravel aggregate products.
In order to further clarify the reasons for the low quality of the stone produced by the equipment, the client hopes to conduct a quality analysis on whether there are quality problems in the involved "sand and gravel aggregate production line" that lead to poor quality of the products produced.
quality analysis results: The
quality analysis expert group discussed and conducted a comprehensive quality technical analysis on the relevant information and on-site investigation and inspection of the "sand and gravel aggregate production line" involved, and made the following recommendations And conclusion: There is no quality problem with the screening equipment of the "Sand and Gravel Aggregate Production Line" involved in
. It is mainly due to improper operation, which leads to clogging of the mesh, increase in fine particles and moisture in the screened materials, excessive thickness of the material layer on the screen, uneven feeding, etc.
