a laboratory study of attrition grinding,this paper descriptionbes the size reduction of limestone smaller than 1 mm by attrition grinding, using quartz (1 to 3 mm) as the grinding medium in a laboratory rig. the ore and grinding medium were closely sized fractions, and the particle size of the grinding medium.comminution by the attrition grinding process,from introduction: 'studies also were made to determine the efficiency of the process in grinding a variety of individual minerals, pigments, metals, and ceramics. as a result of this work, the process was adapted by industry to produce paper-filler-grade kaolin and ultrafine titania pigment on a commercial scale. this report summarizes the results of the bureau's research studies and includes.
the cryomill is a cryogenic grinder designed with user safety in mind. the liquid nitrogen flows through the closed system and the user never comes into direct contact with ln 2 which ensures a high degree of operational safety. the automatic cooling system guarantees that the grinding process is not started before the sample is thoroughly cooled.

photo of autogenous mill at a copper mine. autogenous mills operate, mechanically, similar to the ball mill. they differ in the media they use to break or grind the ore. autogenous mills use large particles of ore instead of steel or other balls for grinding media. autogenous mills use large pieces of ore as grinding
every mining operation has a unique grinding process. variable needs require versatile grinding equipment. we offer flexible autogenous (ag) mills, semi-autogenous (sag) mills, ball, and pebble mills to fit your needs and exceed operational goals.
for the mining industry, our semi-autogenous (sag) grinding mill uses a minimal ball charge in the range of 6-15 percent. it is primarily used in the gold, copper and platinum industries as well as in the lead, zinc, silver, and nickel industries. autogenous (ag) grinding mills involve no grinding media as the ore itself acts as the grinding media.
