1. Main use
The series of products is a kind of high efficiency screw-type sand- washing equipment developed in combination with the reality of gravel industry in China for the use of sand-making machine, mainly for equipment of impurity of sand products(such as dust). The equipment has the functions of washing, dewatering and classifying. It is applicable to sand required for construction sites, gravel, concrete dam of hydropower stations, post poles factory and ‘ seven 0 ‘ sand for casting. Quartz sand for glass factory, washing, dewatering and classifying of the pressure sand for backfill of oil well, suitable for washing operation of fine-grained and coarse-grained material, especially for sand of building construction and gravel for road construction.
2. Advantages
a. Large handling capacity and low power consumption
b. Less wastage of washing materials and high washing efficiency
c. Reasonable structure and stable running
d. Low failure rate and easy maintenance
e. Low failure rate and easy maintenance
f. Conservation of water resources and pollution-free
g. Long performance life
