The material enters the construction waste crusher from the feed hopper, and the material is divided into two parts by the distributor. A part of the material enters the high-speed rotating impeller from the middle of the distributor and is rapidly accelerated in the impeller. The acceleration can reach several hundred times the gravitational acceleration. Then it is projected from the three equally-distributed runners at a speed of 60-70 m/s. It is first impacted by a part of the material falling around the distributor and then impacted by the material liner in the vortex branch. At the top, it is rebounded by the material lining, and it impacts diagonally upwards on the top of the vortex chamber, changes its direction of movement, and deflects downward. The materials emitted from the runners of the impeller form a continuous material curtain. Such a piece of material is subjected to two or more chance impacts, friction, and abrasive crushing within the vortex crushing chamber. The broken material is discharged from the lower discharge port. During the whole process of crushing, the materials are mutually impacted and broken, and they are not in direct contact with the metal components. Instead, they collide with the material linings by impact, friction and crushing, which reduces the angle pollution and prolongs the mechanical wear time. The ingenious airflow inside the vortex chamber self-circulates, eliminating dust pollution.
The material falls into the feed hopper, enters the high-speed rotating rotor through the center feed hole and is fully accelerated and thrown through the launching port. It first collides with a part of the material that is free to fall after rebound, and then hits the surrounding vortex chamber together. The vortex material is lining (or repelling the block) and is first bounced back to the top of the crushing chamber, and then it is deflected downwards and moved downwards to form a continuous material curtain by impact with the material emitted from the runner of the impeller and finally discharged through the lower discharge port. .
The new type of sand making machine uses a diamond combined impact block (head) instead of the original integral hammer head and square combined impact block. The impact block alloy is "hard but not brittle, tough and firm" and has good high temperature resistance. The impact block is directly made of imported high-quality alloy forging, and its wear resistance and toughness are at the leading level in China, which greatly improves work efficiency. Its service life is 3-5 times higher than that of high-manganese steel, and the production yield and quality are improved.
The latest 5X sand making machines have adopted diamond-shaped combined impact blocks. The main feature of this type of impact block is the use of foreign high-quality alloys instead of the domestic traditional manganese steel and cast alloy parts, thereby greatly improving the wear resistance of the impact block Sand and crushing capacity of the sand making machine. The combination of the rhombic impact blocks can also be used in reverse rotation while improving its wear resistance, which not only improves the utilization of the material, but also effectively protects the life of the internal shield of the sand making machine. The overall service life of the sand making machine is more than five times higher than that of the original product. Sand production efficiency increased by more than 30%.
