Fine Sand Recovery Unit Manufacturer | 95% Efficiency

The fine sand recycling machine is an equipment developed for the dehydration, dewatering, and desilting of slurry materials. Its main function is to clean, dehydrate, and classify sand and gravel. It can effectively recover a large amount of fine sand lost by traditional sand washing machines in the sand making industry, improve economic benefits, and reduce the processing cost of tailings and the pollution and damage caused by the loss of fine sand to the environment.

Product introduction

Product Overview
CATHAY fine sand recovery machine is specially designed for sand washing wastewater, integrating cyclone separation + high-frequency dehydration technology to achieve efficient recovery of fine sand (0.075-0.6mm).
