Track-mounted Sand-making Plant

The working principle of the fine crushing and sand washing mobile station is the same as that of the impact sand making machine. The material enters into the sand making machine from the feed hopper, and the material is divided into two parts through the distributor, one part of which enters into the high-speed rotating impeller in the middle of the distributor, and is rapidly accelerated within the impeller with an acceleration up to hundreds of times the acceleration of gravity, and then is projected out with a speed of 60-70 metres per second from the impeller within the three evenly distributed runners and is firstly dropped by the distributor around the part of material impact crushing. Firstly, a part of the material falling around the distributor will be impacted and broken, and then impacted to the material lining layer in the vortex cavity, and then rebounded by the material lining layer, and then impacted diagonally upwards to the top of the vortex cavity, and then change its direction of movement, and deflected downwards, and then the material launched out from the impeller channel will form a continuous flow of material.

In this way, a piece of material in the vortex crushing chamber is subjected to two or more times the rate of impact, friction and grinding and crushing effect. The crushed material is discharged from the lower discharge port. It forms a closed circuit with the circulating screening system, and the material can be crushed into less than 20mesh in three cycles. In the whole process of crushing, the materials are crushed by their own impact, not in direct contact with the metal components, but crushed by impact and friction with the material lining, which reduces the pollution and prolongs the life of the machine. The clever self-circulation of airflow inside the vortex chamber eliminates dust pollution.
