The clay material screening machine - cross screen developed by Shijiazhuang Gongbei Heavy Machinery Co., Ltd. was installed in the soil pollution remediation project of Nanning Chemical relocation undertaken by Guangxi boschke environmental protection Co., Ltd. in July 2016 to screen the contaminated soil materials after the relocation of the plant. The material contains a lot of debris, rope and other impurities, and the treatment process is complex due to the different soil moisture content in different plots, different depths and different seasons.

The general vibrating screening equipment is difficult to meet the environmental protection treatment requirements under complex working conditions and in the urban area. The cross screen produced by Shijiazhuang power double weight machine according to the above soil properties has been successfully tested at one time. The single processing capacity is more than 500t / h, the classification particle size is 25-50mm, and the classification efficiency is 99.8%, which is 70000 m for the user to process within 4 months ³ Soil engineering is guaranteed.
