The particle shape of the finished product processed by Bamak is regular, mostly round or square, with fewer needles and flakes; Drum processing brown corundum is irregular, and there are many needles. Bamak sand making machine is suitable for crushing and molding soft or medium hard and extremely hard materials, and is widely used in various ores, cement, refractories, alumina clinker, emery, glass raw materials, machine-made building sand, stone and various metallurgical slags, especially for hard, extremely hard and wear-resistant materials such as silicon carbide, emery, sintered bauxite and fine sand, with higher output efficiency than other types of crushers. In the engineering field, VSI series crusher is an ideal production equipment for machine-made sand, cushion material, asphalt concrete and cement concrete aggregate.
