(2) rod mill. Cylinder was barreled type, with a metal rod as grinding media, due to the role of selective grinding role, so the product is uniform. It is mainly used in the multi-product efforts for re-election plant.
(3) the pebble mill the steel medium grinding equipment, gravel or hard rock the stones finely ground ore by means of a variety of sizes.
(4) the self-grinding mill. Ores are ground, relying on their own mutual impact in the short barrel. The ore is both a grinding media and grinding material. In order to improve the self-sharpening effect, sometimes adding a small amount (2% to 8%) of steel balls to the cylinder body, it is known as semi-autogenous grinding. The ration of the self-mill crushing is bigger; it can greatly simplify the crushing process.

(5) ultrafine grinding equipment. This type of equipment is mainly used for deep processing of non-metallic minerals; it mainly has mechanical and airflow impact two major classes. Mechanical ultrafine grinding equipment’s pulverization, relying on a variety of high speed rotation body (hammer, blades, shanks, etc.) dispersed the coarse ore particles by centrifugal force in the grinding chamber wall, or giving the mineral particles a certain line speed to make the particles occur the impact collision.
This kind of equipment has many kinds; pneumatic superfine grinding equipment makes use of the high pressure air (compressed air or superheated steam), making the material mutual impact (crash) friction and shearing to realize the crushing purpose. Product size can generally be 1.0 ~ 5.0 um or more fine. This kind of mill has flat type airflow crusher, circulation pipe airflow crusher, jet grinding machine and so on, these grinding equipment is mainly used for the super fine grinding of the material.
