The cone mill is also called the conical screen mill. One of its distinguishable features is a cone-shaped chamber fitted with a rotary impeller/knife. Materials are fed into the cone mill in several ways: Cone mills are highly flexible and widely used for intermediate sizing in wet and dry granulation processes.

CLUM ultra-fine vertical mill is a new type of milling equipment that includes grinding, grading, conveying, secondary powder selection, and finished product packaging. It is a large-capacity ultra-fine grinding and separation equipment developed by us, based on our 20 years of research and operation experience in the grinding industry.

Milling is an essential unit operation used for particle size reduction in solid oral dosage manufacturing. Milling generally follows the granulation or crystallization during API manufacturing. Granulation process is primarily required in processing of drug product

The pumping capacity of an impeller is defined as the volumetric flow rate normal to the impeller discharge area. The pumping capacity of an impeller is proportional to its diameter and speed: QaND3 The head difference between the "suction" and …

A given mill may operate successfully in more than one class: a hammer mill may be used to prepare a 16-mesh granulation and to mill a crystalline material to a 120-mesh powder. The mills used for size reduction of the granules can be divided into two primary categories based on the energy input into the process.

Qualified fine powder would go through the impeller vane of classifier then output the cyclone separator or dust collector, while coarse powder would fall down to the milling chamber to be milled again. Jet Mill is widely used in the pharmaceutical, chemical, mining, food, new materials and other industries.
