CNC vertical shaft sand making machine is suitable for the crushing and shaping of soft or medium hard and extremely hard materials. It is widely used in various ore, cement, refractory materials, bauxite clinker, emery, glass raw materials, machine-made construction sand, stone materials and various This kind of metallurgical slag, especially for silicon carbide, emery, sintered bauxite, meisha and other high-hard, extra-hard and abrasion-resistant materials, has higher output efficiency than other types of crushers.
In the engineering field, it is an ideal production equipment for machine-made sand, cushion material, asphalt concrete and cement concrete aggregate.
In the mining field, it is widely used in the pre-grinding process. It can produce a large amount of fine ore and reduce the high-cost grinding load.
Due to the excellent low abrasion characteristics of this series of sand making machines, this equipment is also used for high abrasiveness and secondary disintegration and crushing production. In addition, the vertical shaft sand making machine can be well adapted to the production of glass quartz sand and other high-purity materials. The production capacity range of 10-500t/h can meet the requirements of conventional sand making.
The material enters the vertical axis machine from the feed hopper, and the material is divided into two parts by the distributor. One part enters the high-speed rotating impeller from the middle of the distributor, and is rapidly accelerated in the impeller. The acceleration can reach hundreds of times the acceleration of gravity. It is ejected from the three uniformly distributed flow channels of the impeller at a speed of 60-70 m/s. First, it is impacted and crushed with a part of the material that has been collected around the distributor, and then impacted on the material lining in the vortex cavity. The material lining rebounds and impacts diagonally upwards to the top of the vortex chamber, and then changes its direction of motion, deflects to move downwards, and the material emitted from the impeller runner forms a continuous material curtain. Such a piece of material is subjected to two or even multiple chance impacts, frictions and grinding and crushing effects in the vortex crushing cavity. The crushed materials are discharged from the lower discharge port. In the whole crushing process, the materials will impact and crush by themselves without direct contact with the metal elements, but will impact and friction with the material lining to crush, which reduces corner pollution and prolongs mechanical wear time. The ingenious air flow self-circulation inside the vortex cavity eliminates dust pollution.
