Design and study of the unsized power coal dry cleaning process

The paper starts with an introduction to the technical features of the intelligent dry cleaning machine,traditional pneumatic separator and small coal dry cleaning jig.Then,the unsized power coal dry cleaning process is proposed for the Liuyuanqu Coal Preparation Plant in west Mongolia Autonomous Region.The process is designed under the perquisite of guaranteeing the product quality.As evidenced by the result of comparison of 4 alternative dry cleaning processes,the use of the designed drying cleaning process can make up the limitations of the traditional dry cleaning processes,and result in reduction of initial capital and operating costs.
