Application and research of high pressure filter press in Xieqiao Coal Preparation Plant
In order to achieve the production goal of efficient and clean utilization of coal slime,Xaiqiao Coal Preparation Plant has upgraded its equipment and adopted a new type of high-pressure filter press to treat coal slime.Through the investigation test of the feeding time,pressing time and pressing pressure of the high-pressure filter press,it can be seen that under the conditions of feeding time 4000s,pressing time 1600s and pressing pressure 2.9 MPa,the water content of the coal slime filter cake is 17.9％and the thickness of the filter cake is 2.90 cm,which meets the actual production needs.The use of high-pressure filter press can produce benefits of about 22.4 million yuan,and the economic benefits are significantly improved.
