Unwinding machine
A specialized device for releasing the cylinder formed by rolling a single board.
Winder
The material collection part of the coil processing production line involves mechanically winding raw materials into coils, which are widely used in paper, cloth, plastic, and metal coil processing production lines. Diversified designs are made according to actual process requirements, including simple and hydraulic coiling machines. Generally, the coiling machine has strict requirements for the material's inner diameter, outer diameter, thickness, and width.
The metal coil winding machine is widely used in continuous operation production lines such as acid pickling production lines, polishing production lines, 8K mirror steel production lines, slitting machine production lines, color drawing production lines, annealing production lines, etc. The winding machine is a non-standard equipment.
Sander 
Sanding machine is suitable for crushing and shaping soft, medium hard, and extremely hard materials. It is widely used in various ores, cement, refractory materials, bauxite clinker, emery, glass raw materials, machine building sand, stone materials, and various metallurgical slag.
Sanding machine (sanding machine) is suitable for crushing and shaping soft, medium hard, and extremely hard materials. It is widely used in various ores, cement, refractory materials, bauxite clinker, emery, glass raw materials, machine building sand, stone materials, and various metallurgical slag. Especially for high hard, extra hard, and wear-resistant materials such as silicon carbide, emery, sintered bauxite, and sand, the production efficiency is higher than other types of crushers.
In the field of engineering, it is an ideal production equipment for machine made sand, cushion materials, asphalt concrete, and cement concrete aggregates.
In the mining industry, it is widely used in the pre grinding process, which can generate a large amount of fine ore and reduce the high cost grinding load.
Due to the excellent low wear characteristics of sanding machines (sanding machines), this equipment is also used for high wear resistance and secondary disintegration crushing production. In addition, due to zero pollution to the product, the impact crusher is well suited for the production of glass quartz sand and other high-purity materials. With a production capacity range of 10-500t/h, the impact crusher can almost meet any production requirements.
Working principle of sanding machine
The material enters the sanding machine (sanding machine) from the feeding hopper, and is divided into two parts through a distributor. One part enters the high-speed rotating impeller through the middle of the distributor, and is rapidly accelerated within the impeller, with an acceleration of several hundred times the gravitational acceleration. Then, it is ejected from the three evenly distributed flow channels of the impeller at a speed of 60-70 meters/second. Firstly, a part of the material that falls from around the distributor is impacted and broken, Then they impact together on the material lining layer in the vortex support chamber, which bounces back by the material lining layer and obliquely impacts the top of the vortex chamber, changing its movement direction and deflecting downwards. The material emitted from the impeller channel forms a continuous material curtain. Such a material is subjected to two or even multiple chances of impact, friction, and grinding crushing in the vortex crushing chamber. The crushed material is discharged from the lower discharge port. During the whole crushing process, the materials collide with each other and break without direct contact with metal components. Instead, they collide and rub with the material lining, resulting in crushing. This reduces corner pollution and prolongs mechanical wear time. The clever airflow self circulation inside the vortex chamber eliminates dust pollution
