AI Technical Summary

Technical Problem

Existing cement classifiers are prone to clogging during the screening process, resulting in low classification efficiency and an inability to effectively separate cements of different fineness, which affects subsequent processing efficiency.

Method used

A high-efficiency cement classifier was designed, which adopts a quantitative screening mechanism and a multi-stage separation mechanism. Through the coordinated work of components such as servo motors, stepper motors, crushing rollers, bevel gears and fans, the cement is crushed, screened and graded. The cement is separated by wind power and gravity, avoiding clogging and improving screening efficiency.

Benefits of technology

It enables efficient batch crushing and screening of cement, reduces the probability of secondary screening, improves powder selection efficiency, and can collect cement according to fineness classification, which facilitates subsequent processing.

Abstract

This utility model provides a high-efficiency cement classifier, relating to the field of cement processing technology. It includes a shell with a feed hopper fixedly connected to the top. A quantitative screening mechanism is installed on the outer side of the shell. The quantitative screening mechanism includes a servo motor, the bottom of which is fixedly connected to the top of the shell. A partition is fixedly connected to the output end of the servo motor. Two stepper motors are fixedly connected to the outer side of the shell, and crushing rollers are fixedly connected to the output ends of the stepper motors. This utility model crushes and screens cement in batches, and disperses and further screens accumulated cement, ensuring that the cement achieves better quality after a single screening, reducing the probability of secondary screening, lowering cement loss, and improving classification efficiency. By setting up a multi-stage sorting mechanism, the screened cement can be promptly blown and graded, quickly separating into three parts according to fineness, facilitating the collection of cement of different finenesses for subsequent processing.
