> Case Introduction

In the process of Sanme wet sand making, new sand making machine has replaced the rod mill with high running cost, which greatly improve the reliability of artificial sand production, and ensure the quality of product. The process is specifically designed for the material less than 40mm(material will be primarily and secondarily crushed by jaw crusher, cone crusher, impact crusher, etc to the size less than 40mm), vertical shaft impact crusher(sand making machine) is used in the configuration of production line, this crusher is the new type sand making machine of Sanme, which has the features of high crushing efficiency(with the function of fine crushing and coarse grinding), simple structure, easy installation and maintenance, low operation cost and excellent particle size(cubic shape, low content of needle-like particles).

Aggregate with size of 0-40mm will be conveyed by electromagnetic feeder and belt conveyor to vertical shaft impact crusher for crushing, the crushed material will be conveyed to vibrating screen for screening, the material with size larger than 5mm will be conveyed back to impact crusher for crushing to achieve a closed circuit. The material with size less than 5mm will be conveyed to sand washer for cleaning, the cleaned material will be conveyed by belt conveyor to final product pile. In order to ensure the fineness module and sand grading, the sand washing water will be recycled by fine sand collection system to collect the fine sand with size less than 0.16mm.
