The ball mill KM 0 (with 0,5 l volume, working capacity of max. 40% and made of stainless steel) is attached to the drive unit via the ER-WEKA Universal Gear. The drum is available with 0.5, 5 or 10 l volume. ERWEKA CM (Conical Mill) The Conical Mill is a product infeed system for application in developments in the pharmaceutical and food ...

This way, a lot of samples can be ground to < 0,25 mm or even finer. A high-performance cyclone separator is required with this setup. With this trial, we used sieve shells of 0,2 mm trapezoidal perforation. We prepared a batch of 70 grams and fed the sample continuously into the feeding funnel.

This ball mill is typically designed to grind mineral ores and other materials with different hardness, and it is widely used in different fields, such as ore dressing, building material field, chemical industry, etc. Due to the difference of its slurry discharging method, it is …

Grid ball mill consists of the shell, feeding part, discharging part, main bearing, lubricating system, driving system and other parts. There is wearing a liner inside the shell, and both ends of the shell are provided with a flange. The end cover of the mill is connected with the flange plate. The feeding part consists of the head, trunnion ...

A method of producing nanoparticles can comprise milling a plurality of milling bodies sufficient to produce the nanoparticles from exterior surfaces of the plurality of milling bodies. In this manner, the milling bodies are simultaneously the milling media and the feedstock for production of nanoparticles such that additional solids are not present during milling.
