NETZSCH Classifier Mills CSM Fine Impact Milling Business Unit GRINDING & DISPERSING

Classifier Mills for Fine Impact Milling Single stage milling is often insufficient for the production of extremely fine particle size distributions of soft to medium hard materials (up to 3 Mohs). In such cases, conventional fine impact mills are often additionally equipped with screening machines or classifiers to classify the milled product. Undesirable coarse particles are returned to the mill to be ground again. This type of separate processing requires a considerable expenditure of machinery. So-called classifier mills offer the possibility of having the same milling-classifying-effect in one...

Functional Description The milling product is fed either via gravity through a downpipe (1) or pneumatically through an injector on the housing (2). The milling product then moves along the inside of the guide ring (3), past the beater classifier wheel (4), which sifts out already present fines, to the beater rotor (5) whose beaters (6) accelerate and then propel it into the peripheral milling track (7). The optimum angle and speed of impact of the milling particles are the result of the perfectly tuned geometries of the beaters and peripheral milling track. The peripheral milling track (7) can...

Highly Efficient and Application Oriented Your Advantage is Our Focus Highly efficient milling device with quick change beating elements and dual-use milling track, specially tuned to the needs of impact milling. Achieves a high range of particle size distributions and high throughput capacities with little rise in temperature. High precision classifier for exact limitation of the particle range in the milled product, free of oversized particles. A co-rotating immersion tube and optimum design produce the highest degrees of fineness. Large machines working with only one classifier wheel also produce...

Optimal and low vibration operation of the classifier mill is achieved with the extremely robust design of the complete machine construction, with its welded machine housing and the coaxial construction of grinding disc and classifier wheel. Application oriented product feed either through gravity via a down pipe or pneumatically via ground level conveyance through an injector or suction air. Easy access to the milling chamber and classifier allows for simple cleaning and maintenance. When the hinged mill lid is open, the milling elements and classifier wheel are immediately accessible. The machine...
