LUM vertical roller mill is widely used in chemical, metallurgical and non-metallic mineral industries. Applicable materials: Mohs hardness below 5, the density of 3.2 or less, compressive strength 150Mpa following, non-flammable mineral, non-corrosive materials brittle granular and powdered materials.
A vibration mill is a size reduction equipment that applies the process of continuous impaction in carrying out its size reduction function. The grinding container is made up of a tube that is held in a frame that is supported by means of springs which is filled to approximately 80% total volume with porcelain or stainless steel balls.
