V type powder selecting machine

Abstract

The invention relates to a powder selecting machine in the technical field of material powder selecting, in particular to a V type powder selecting machine which is used cooperatively with a roller press or a vertical mill to powder, dry and grade materials. The V type powder selecting machine comprises a feeding shell body, a wind inlet shell body, wind-inlet-side adjustable blades, wind-outlet-side adjustable blades, a powdering and grading blade set, a powder selecting shell body, a wind outlet shell body, a rotation-powdering device, a fastening component and the like, wherein the rotation-powdering device is arranged on the feeding shell body, a main wind inlet and a lower wind inlet are formed in the wind inlet shell body, and a wind-inlet-side adjustable blade device and a wind-outlet-side adjustable blade device are arranged on the powder selecting shell body; the powdering and grading blade set is arranged in the powder selecting shell body, a coarse powder outlet is formed in the lower portion of the power selecting shell body, and a wind outlet is formed in the wind outlet shell body. According to the V type powder selecting machine, the structure is compact, the powering and grading efficiency is high, the adjustment of a grading particle size can be achieved through the wind-inlet-side adjustable blade device and the wind-outlet-side adjustable blade device, the operating-condition adaptability is high, and the powder selecting efficiency is high.

Description

technical field [0001] The invention relates to a powder separator in the technical field of material powder separation, in particular to a V-type powder separator used in conjunction with a roller press or a vertical mill to disperse, dry and classify materials. Background technique [0002] 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 functions of dispersing, drying and grading materials. In the building materials and cement industry Has been widely used. However, the current V-type powder separator still has some problems in use. For example, the dispersing plate cannot fully disperse the material, and the dispersing effect is poor, resulting in the inability to form a uniformly dispersed material curtain, and some suitable particles enter the separation area without being separated. After being selected, it falls to the coarse p...

AI Technical Summary

Problems solved by technology

However, the current V-type powder separator still has some problems in use. For example, the dispersing plate cannot fully disperse the material, and the dispersing effect is poor, resulting in the inability to form a uniformly dispersed material curtain, and some suitable particles enter the separation area without being separated. After being selected, it falls to the coarse powder outlet, and the efficiency of powder selection is low. The lower part of the powder separator is not equipped with a lower air inlet, and the section of the air inlet and outlet shell is not equipped with a wind speed adjustment device. If the system parameters or material conditions change greatly, it cannot be adjusted. , affecting the dispersion and grading effect of the powder classifier
