The ConJet high-density bed jet mill is a spiral jet mill combined with a patented dynamic air classifier. This classifier enables the ConJet to achieve highest finenesses independent of the product load, and therefore also highest throughput rates. Applicable for finenesses from 2.5 to 70 m (d97). Machine sizes available for grinding air volumes from approx. 50 to 2,400 Nm /h

Dec 09, 2021 Product Line Description. Mikro ACM - Air Classifying Mills which was invented by HMPS in the late 1960’s is one of the most versatile size reduction equipment available in the market. These units while being capable of producing fine, medium and coarse grinds for wide variety of materials for Food, Pharmaceutical, Chemical and Mineral industries require very little maintenance over their

Aug 19, 2019 The coolant and grinding wheel are equally important tools in the roll grinding process. One of the key factors in achieving and maintaining grinding quality and a safe grinding environment is water purity. Importance of Water Purity. Using contaminated water in a coolant mixture can cause a multitude of problems in roll grinding operations

Nov 04, 2021 A large number of studies have shown that the height of a residual material is the key factor affecting the surface quality of ultra-precision grinding. However, the grinding process contains several random factors, such as the randomness of grinding particle size and the random distribution of grinding particles, which cause the complexity of the material removal process
