Sand production line quality appraisal

sand making production line is composed of vibrating feeder, crusher, sand making machine (fine crusher), sand washing machine, screening equipment and belt conveyor. Users can make their own combinations according to different process requirements to meet different process requirements.
sand making production line equipment can be used for aggregate and artificial sand making operations of hard limestone, granite, basalt, river pebbles, smelting slag and other materials. It is suitable for applications in hydropower, building materials, highways, urban construction and other industries.
In the case of sand making production line quality appraisal, Zhongke Testing can provide sand making production line quality appraisal services.

sand making production line usually includes: vibrating feeder, impact crusher, cone crusher, vibrating screening machine, sand washing machine, and conveying equipment.

The vibrating screen structure of the sand production line purchased by a sand making plant cracked, the cone crusher overran, and there was an issue with the assembly gap of the bowl-shaped tile frame and oil leakage. The technical requirements agreed upon in the agreement were not met, and a dispute arose with the equipment manufacturer.
was entrusted by the court to conduct an appraisal and analysis on "whether there are quality problems" in the sand-making production line involved in the case.
identification analysis results:
identification analysis expert group discussed the relevant information and on-site investigation of the sand production line involved in the case and conducted a comprehensive quality and technical analysis, and made the following suggestions and conclusions:
involved in the case The subsequent maintenance of the cone crusher of the sand production line is a remedial measure to reduce the assembly, but the uneven wear gap of the lower frame shell continues to exist. The cement-containing sand can enter the interior of the body through the straight gap of the steel backing plate. At the same time, the lubricating oil in the body will leak through the gap; the cracking of the vibrating screen structure is a welding quality problem.
