AI Technical Summary

Technical Problem

In a horizontal sand mill with a vertical output, the grinding media tends to accumulate at the outlet, resulting in poor grinding effect and difficulty in discharging the material. Furthermore, the grinding media can easily enter the discharge channel with the material, leading to ball leakage.

Method used

The horizontal sand mill with vertical centrifugal discharge uses separation pipes, separation paddles, self-suction cups and other structures to control the movement trajectory and speed of materials and grinding media, thereby achieving separation of materials and grinding media, preventing grinding media from entering the discharge channel and promoting the circulation of grinding media in the grinding cylinder.

Benefits of technology

It effectively avoids the grinding media clogging the discharge channel, improves grinding efficiency, ensures smooth material discharge, and increases the circulation rate of the grinding media in the grinding cylinder.

Abstract

This invention discloses a horizontal sand mill with vertical centrifugal discharge, comprising a grinding rotor and a grinding cylinder, wherein grinding blocks are mounted on the grinding rotor; an outlet of the grinding cylinder is located on one side, connecting to the discharge port of the horizontal sand mill; a separation pipe is provided between the outlet of the grinding cylinder and the discharge port of the horizontal sand mill, and a first protrusion is provided on the inner wall of the separation pipe, the first protrusion being a wavy structure with multiple continuous protrusions, and the protrusions closer to the discharge port of the horizontal sand mill having a higher height on the inner wall of the separation pipe; a separation paddle is also provided between the outlet of the separation pipe and the discharge port of the horizontal sand mill, the separation paddle comprising paddle blades and a paddle hub for mounting the paddle blades and driving the paddle blades to rotate, the separation paddle imparting a vertically downward velocity component to the slurry through the paddle blades. This invention can prevent ball leakage at the discharge port and accelerate the circulation of the grinding media in the grinding cylinder by controlling the movement trajectory and speed of the material and grinding media, thereby improving grinding efficiency.
