PTMS MAGNETIC SEPARATOR
what is magnetic separation method in hindi？
The mine may be familiar to everyone, but the equipment may not have been known. In today's mining machinery industry, construction industry, sand and gravel industry, the crusher is no longer strange to everyone, and various types of crushing machinery and crushing equipment are making outstanding contributions in their field of use. Who invented the crusher first?
In fact, the crusher has appeared more than 100 years ago, and after many improvements it has become the model we are using now. In the future, the crusher will change further as people demand:
The first jaw crusher was designed and manufactured by the Americans in 1858. The structure is a double-knuckle jaw crusher. The jaw crusher can be used for rough grinding or for medium and fine work. In particular, it is used in downhole crushing operations and medium and small mobile crushing devices. . The gyratory crusher is widely used in large and medium-sized concentrators and large quarries to coarsely crush various hardness rock minerals.
It can discharge the non-breakable material entering the crushing chamber during the operation of the machine, and can adjust the size of the discharge port during operation, which is the uniform granularity of the crushed articles; in the 1970s, it was developed into an automatic controller for controlling the hydraulic cone crusher. The cone crusher has the advantages of large crushing ratio, high efficiency, low power consumption and uniform product size. Suitable for medium, fine and ultra-fine crushing of hard rock mineral materials.
The hammer crusher first appeared in 1895. It is widely used in industrial sectors such as cement, coal preparation, thermal power generation, metallurgy, and refractory materials. The hammer crusher can be divided into two types: single rotor and double rotor. The single rotor can be divided into two types: irreversible and reversible. Its specifications are indicated by its rotor diameter and length.
The new high-efficiency crushing equipment of the impact crusher appeared in the market after the second war (1945). The designer of the first impact crusher was Dr. Hedson of the former West Germany Hazelmann. It can be used in cement, asbestos, thermal power, glass, chemical, building materials, metallurgical and other industrial sectors for the coarse, medium and fine crushing of brittle materials such as limestone, asbestos, coal and calcium carbide. The impact crusher can be divided into two types, single rotor and double rotor, and its specifications are expressed by its rotor diameter and length.
The roller crusher appeared in 1806. Due to its simple structure and easy manufacture, especially its products are less pulverized, it is still in the industrial sectors such as coal preparation, sintering, cement, glass, ceramics, and small concentrators. Especially in the dressing laboratory. The roller crusher can be divided into a single roll, a counter roll and a multi roll type. The roller crusher can be divided into two types, an optical roller and a tooth roller, according to the surface condition of the roller.
