The SK 300 can be used for the preparation of medium-hard and hard materials such as: soil, slag, ores, minerals, ceramics, etc. The sample loaded into the dosing hopper is crushed by the beater knives rotating in a closed space by the crushing edges on the wall of the grinding chamber and the door, and then the sample passes through a bottom sieve into the collection container. The grinding device can be made of four types of materials - cast iron, chrome steel, stainless steel and special heavy metal-free steel - with a grinding chamber according to the use. The bottom sieves in the device are replaceable, so the particle size of the final product can vary over a wide range. The device can be operated mounted on a table or stand (option). Accessories: three-knife parallel impact rotor, filter stocking, 5 liter collection container. Bottom sieves must be ordered separately.
