Annular V-selection composite powder concentrator

Abstract

The invention discloses an annular V-separation combined type powder concentrator which comprises a machine body, a feeding opening is formed in the top of the machine body, a discharging opening is formed in the bottom of the machine body, an air inlet is formed in one side of the machine body, an air outlet is formed in the other side of the machine body, a winnowing cavity is formed in the machine body, a discharging assembly is arranged at the top of the discharging opening, and a material distributing assembly is arranged at the bottom of the discharging opening. According to the invention, the sorting efficiency can be greatly improved, the vibration hopper can generate vibration, the vibration hopper can drive materials at the top of the vibration hopper to vibrate in the vibration process, large-particle materials are distributed on the vibration hopper, small-particle materials are distributed on the vibration hopper, the materials can be dispersed and prevented from being wrapped together to affect sorting, and the vibration hopper moves left and right back and forth, so that the sorting efficiency is improved. According to the winnowing device, the material blocking plate is arranged, so that sliding materials can form a uniform material curtain, the sorting efficiency is greatly improved, fine particles can penetrate through the position below the material blocking plate, coarse particles are blocked by the first material blocking plate and cannot slide, the coarse particles sliding into the winnowing cavity can be reduced, and the blocking probability is reduced.

Description

technical field [0001] The invention relates to the technical field of powder separators, in particular to an annular V-selection composite powder separator. Background technique [0002] Separators are widely used in coal mills, raw meal unloading drying mills and cement mill systems in new dry process cement production lines. It can be divided into three categories: three-separation powder separator, centrifugal powder separator and cyclone powder separator. The V-type powder separator is a static grading and dispersing equipment specially used for the roller press. It can separate the qualified fine materials from the roller press material, which is conducive to the smooth operation of the roller press, improves the output of the system, and has the function of drying. dry function. At present, in the building materials and metallurgical industry, the V-type powder separator can form various grinding process systems with roller presses or vertical mills because of its f...

AI Technical Summary

Problems solved by technology

[0003] The current V-type powder separator also has some problems in use, such as the inability to form a uniformly dispersed material curtain, resulting in a small contact area between the winnowing air flow and the material, and some suitable fine particles are wrapped by coarse particles. Coarse powder is exported, and the efficiency of powder selection is low
