Material pulverizer for precise screening

Abstract

The invention discloses a material pulverizer for precise screening. The material pulverizer is a cylindrical shell, a separating screening mesh is arranged in the middle of the shell, the shell is divided by the separating screening mesh into an upper smashing bin and a lower secondary separating bin, a conical flow guide plate is arranged on the lower portion of the separating screening mesh, a light material collecting tank is arranged on the inner side of the flow guide plate, a heavy material collecting tank is arranged on the outer side of the flow guide plate, a feeding opening is formed in the middle of the flow guide plate, a circle of blower pipeline is arranged at the position, below the heavy material collecting tank, of the shell of the pulverizer, and a circle of material blocking baffles is arranged above the feeding opening. According to the material pulverizer, smashed small particle solid materials are screened and separated again through the conical flow guide plate and the blower pipeline under the dual action of gravity and airflow, the separating range of the solid materials is controlled by regulating and controlling the air outlet quantity, control is precise, and different production needs of the solid materials of different weights or sizes are met.

Description

Technical field [0001] The invention involves the field of material processing equipment, especially a material crusher that is convenient and practical for accurate sieve. Background technique [0002] Material crusher is one of the commonly used production equipment commonly used in solid materials for large particles. The solid material of large particles is too slow during the reaction process of liquid solvent, which will affect the reaction efficiency of the overall reaction.Therefore, the large particles of solid materials are crushed into small particles with a solid material of small particles, which is conducive to saving response time. [0003] Ordinary material crushing machines only crush the large particles into small particles within a specified diameter, but due to the uncertain type of the material during the crushing process, the material of small particles also has different quality or volume particles. For the particles of different quality or volume.Special c...

AI Technical Summary

Problems solved by technology

[0003] Ordinary material pulverizers only crush large-grained materials into small-grained materials within a specified diameter range, but due to the uncertainty of the material in the crushing process, small-grained materials still have particles of different masses or volumes. For special chemical reactions, solid materials with different masses or volumes have different uses, and further screening work is required. During the screening process, it is very difficult for fine particles of solid materials to pass through the filter screen, and it is difficult to filter them with different particle sizes particles are completely separated
