Small Sand Making MachineLast Update:2020-05-13 14:01:57
The small sand making machine refers to the small sand making machine equipment with an hourly output of less than 50-80t, which is applied to hard materials, but also to the fine and ultra-fine crushing of the industries such as artificial sand making, pre grinding cement, mining, refractory materials with very different material properties, such as granite, basalt, limestone, quartz, gneiss, cement clinker, concrete aggregate, ceramic raw materials, iron ore, gold Ore, copper, corundum, bauxite, silica, etc. The materials fall vertically into the high-speed rotating impeller from the upper part of the machine. Under the action of high-speed centrifugal force, they collide and crush with the materials distributed around the impeller in the form of umbrella. After the materials collide with each other, they will collide and rub with each other for many times between the impeller and the shell, and then they will be discharged directly from the lower part, forming a closed circuit and multiple times of circulation The ring is controlled by the screening equipment to reach the required particle size of the finished product.
According to the structure of the rotor, the small sand making machine can be divided into open rotor structure and closed rotor structure. The closed rotor structure is a cage layout of the rotor. After the material falls into the closed rotor from the top, it is thrown out at high speed. The open rotor structure is that the rotor is an open structure, after the material falls into the rotor, it is hit by the throwing hammer. In terms of the working principle of the impact crusher, it is simply the principle of stone striking. Let the stone collide with the stone accelerated by the impeller in the process of natural falling, so as to achieve the purpose of breaking! When the stone accelerated by the impeller collides with the stone falling naturally, a vortex is formed, and the stone is broken twice in the process of returning, so there is little wear on the reaction plate of the machine in the process of operation!
3. Change three-stage crushing into two-stage crushing, with large production capacity, long service life of hammer head, environmental protection and energy saving. It is widely used in the crushing of granite, basalt, cement, quartz, emery, mineral sand, iron ore, bauxite, and other raw materials, which is better than pebble. It overcomes the disadvantage that the traditional sand control equipment is only suitable for soft rock (150MPa) raw materials.
The material enters the sand making machine from the feed hopper. The material is divided into two parts by the distributor. One part enters the high-speed rotating impeller from the middle of the distributor. It is accelerated rapidly in the impeller, and its acceleration can reach hundreds of times of the gravity acceleration The speed of 60-70m / S is ejected from the three evenly distributed flow channels of the impeller. First, some materials falling from the distributor are impacted and broken together, then they are impacted on the material lining in the vortex support cavity together, rebound by the material lining, and impact obliquely upward to the top of the vortex chamber, and change the direction of movement, deflect downward movement, and the materials emitted from the impeller flow channel form a connection Continued material curtain. Such a material is subjected to two or more chances of impact, friction and grinding in the whirling crushing chamber. The crushed material is discharged from the lower discharge port. In the whole process of crushing, the materials impact each other to break, not directly contact with metal components, but impact and friction with the material lining, which reduces the angle pollution and prolongs the mechanical wear time. The air flow inside the whirlpool chamber circulates automatically, eliminating dust pollution.
After long-term technical research and international exchanges, the quality and technical content of Caesar's products have reached the first-class level in the world, and have been widely recognized and praised in the international market; the products are exported to more than 160 countries, such as the United States, Russia, etcGet Price Now
