Novel dual-transmission combined efficient sorting machine

Abstract

The invention discloses a novel dual-transmission combined efficient sorting machine. The machine comprises a feeding port, a finished product collector, an upper powder selection chamber and a main support. The main support penetrates and fixes the upper powder selection chamber, a middle powder selection chamber and a lower powder selection chamber. The upper powder selection chamber is connected with the middle powder selection chamber which is connected with the upper powder selection chamber. The upper end of the upper powder selection chamber is connected with the feeding port, and two sides or the periphery of the upper powder selection chamber are or is connected with the finished product collector. A guide blade and an upper rotor are arranged in the upper powder selection chamber, and the upper rotor is disposed on the inside of the guide blade. A scattering plate is arranged above the retaining plate which is arranged above the upper rotor and the guide blade. A middle tapered element is arranged in the middle powder selection chamber, and the upper end of the middle tapered element is connected with the upper powder selection chamber. A coarse powder returning port is formed in the lower end of the lower powder selection chamber, and a lower rotor is arranged in the lower powder selection chamber. By means of the machine, the efficiency and the yield of grinding equipment are improved, and steel consumption and power consumption of the grinding equipment are reduced.

Description

technical field [0001] The invention relates to the field of separation of building materials, metallurgy, and chemical powder materials, in particular to a novel dual-drive combined high-efficiency separator. Background technique [0002] In the processing of split materials in the fields of building materials, metallurgy, and chemical industry, the bulk materials are often ground and sorted by a powder separator, and then the fine powder that meets the material standards is processed into finished products, which do not meet the requirements. The standard coarse material is sorted by re-grinding, but after the existing powder classifier spreads the material through the spreading plate, the material enters the powder selection chamber for only one sorting, which leads to incomplete separation of coarse powder and a large amount of Fine powder and coarse powder are mixed together into the lower cone, and returned to the grinder for re-grinding. Mixing fine powder and coarse ...

Problems solved by technology

[0002] In the processing of split materials in the fields of building materials, metallurgy, and chemical industry, the bulk materials are often ground and sorted by a powder separator, and then the fine powder that meets the material standards is processed into finished products, which do not meet the requirements. The standard coarse material is sorted by re-grinding, but after the existing powder classifier spreads the material through the spreading plate, the material enters the powder selection chamber for only one sorting, which leads to incomplete separation of coarse powder and a large amount of Fine powder and coarse powder are mixed together into the lower cone, and returned to the grinder for re-grinding. Mixing fine powder and coarse powder into the grinder for grinding will intensify the repeated work of the grinder and increase the loss of steel balls in the grinder. And because the pulverizer is a kind of high energy consumption equipment, it will increase the production cost accordingly, and at the same time, it will also lead to low powder selection efficiency of the powder separator. The low selection rate is generally about 55%, low output and high energy consumption of the system
