Yihong XZM Ultrafine Mill in INDIA

Yihong  XZM Ultrafine Mill in INDIA

Case Study
A mining company in India intends to produce calcium carbonate powder with fineness of 5-10 micron; Required capacity is 1.0 ton

per hour. They had a Raymond mill which can not meet their desired fineness. The feeding size of the raw stone is 12"-14". They

have a primary 16"×10" jaw crusher. Based on customer’s situation, we recommended full set of XZM221 Ultrafine mill for their

requirement. The mill was installed in 2009 and is running perfectly in India now.
Production Process
Raw material of 12"-14" size is primarily crushed by the client’s jaw crusher down to 2" and then enters our hammer crusher PC400

×300, after secondary crushing, it will be less than 0.4", and discharged to bucket elevator. The elevator sends the material to

storage hopper, there’s a vibrating feeder under the hopper, the feeder feeds material to main unit of XZM221 mill evenly and

continuously. When the material being ground in the mill, the blower blows the powder to classifier, the classifier impeller is

rotating at adjustable speed which is controlled from control cabinet, as per client’s requirement, powder less than 10 micron

will be separated by classifier, and bigger powder falls down, being reground over and over again. 10micron and less than 10micron

powder then go to the cyclone collector with the air from blower and be collected in the cyclone collector. Powder will be

discharged from the discharge valve to become the final products. The bag filter will clean the outgoing air to protect the

environment.
