1.Based on market experiences, the company invents the grinding and waterfall shaping technology and improves the impact crushing mode. Now, the proportion of fine sand with 0-0.6mm has been greatly increased, and the problem about materials with big head and small body is overcame. Besides, the fluidity of finished sand has been effectively improved. 2.The finished products are mainly square and spherical. There are no materials like needle and the shape is round. The burrs and edges on the surface are greatly reduced. The surface area and porosity are obviously reduced, and the fluidity is greatly improved. 3.The powder removal technology with dry process can keep powder content stable. At the same time, the stone powder separated by dry process is dry and clean, which is convenient for unified recovery and comprehensive utilization. 4.The equipment is equipped with intelligent control system, which can start and stop machine just by one key. And this system can help monitor the status of equipment.
