A horizontal bead mill with full zirconia ceramic grinding inner cavity and dial

Abstract

The invention relates to a horizontal bead grinding machine with a full zirconia ceramic grinding inner cavity and a driving plate. The bead grinding machine comprises a frame, a grinding unit, a mechanical diaphragm pump, a cooling tank and a connecting pipeline, wherein the grinding unit comprises a grinding cavity, a mechanical seal seat, a cavity frame, a main shaft, a propulsion screw rod, a rigid coupling, a motor and a mechanical seal; the mechanical seal seat is fixed to a motor flange via screws; a moving ring of the mechanical seal is locked on the main shaft by via a pin; a static ring of the mechanical seal is fixed to the mechanical seal seat; the mechanical seal enables cavities to be formed at two ends of the main shaft; the cavity frame is arranged on the outer side of the propulsion screw rod; the motor drives the main shaft to run through the rigid coupling; and the propulsion screw rod, a zirconia seal wheel in the grinding cavity and the driving plate are connected with the main shaft through keys; so that power is provided to the zirconia seal wheel in the grinding cavity and the driving plate. With the bead grinding machine, the wear resistance of the whole bead grinding machine can be enhanced effectively; the quality of the bead grinding machine is improved; the service life of the bead grinding machine is prolonged simultaneously; and production cost is reduced.

Description

technical field [0001] The invention relates to a horizontal bead mill, in particular to a horizontal bead mill with a full zirconia ceramic grinding inner wall and a dial. Background technique [0002] The commonly used horizontal bead mill is a machine that is used to grind materials in a flat fixed cylindrical grinding chamber, equipped with several rotating grinding discs (or levers or rod pins) and various grinding bodies. Grinding media are usually Ottawa sand, glass beads, steel beads or ceramic beads, etc. The material is subjected to the comprehensive action of strong shearing, centrifugal extrusion, liquid layer friction, impact tearing and turbulence in the grinding cavity, and the filter screen with a specific gap at both ends is forced to filter, so as to make it incompatible. Under the combined action of the corresponding mature technology and appropriate amount of additives, the solid phase, liquid phase and gas phase of the powder are emulsified evenly and f...

AI Technical Summary

Problems solved by technology

[0003] The horizontal bead mill in general application is made of stainless steel, hard alloy steel or lined with polyurethane, zirconia ceramics and other materials due to its cylindrical grinding chamber and rotating grinding disc (or lever), and the filter screen is made of carbon steel, stainless steel, etc. And other materials, through production practice, its wear resistance is not good and the pollution to the material is affected by the structure, the service life cycle is not ideal, especially the service life of the filter screen is particularly limited

In addition, although some common horizontal bead mills are equipped with booster impellers on the main shaft, when grinding materials with high viscosity, the working resistance of the filter screen is relatively large, resulting in low production efficiency.
