This machine integrates crushing and grading, and is a new type of combination equipment. It has the advantages of novel design, compact structure, easy maintenance, low energy consumption, high efficiency, and uniform particle size; This machine is equipped with a grading mechanism, which can easily separate the grading and crushing parts for easy maintenance and cleaning; Without stopping the machine, the particle size can be adjusted arbitrarily, with a narrow particle size distribution surface and a fineness of up to 5-8um; Vulnerable parts are refined from special wear-resistant materials. The ideal equipment for ultrafine grinding processing widely used in industries such as pharmaceuticals, chemicals, feed, plastics, food, non-metallic minerals, etc.
