Cement wet grinder

Abstract

The invention discloses a cement wet grinder. The cement wet grinder is characterized by comprising a shearing dispersator, a mixing tank and a shearing colloid grinder, wherein the shearing dispersator comprises a stirring motor, a dispersing plate, a mixing paddle and a smashing plate, the stirring motor is connected with a transmission shaft, the transmission shaft is provided with the mixing paddle and the dispersing plate, the bottom part of the transmission shaft is provided with the smashing plate, the top part of the mixing tank is provided with a cement material inlet and a circulating pipe, the bottom part of the mixing tank is provided with a material outlet pipe, the material outlet pipe is connected with a cement slurry outlet and the shearing colloid grinder, the shearing colloid grinder comprises a motor and a wet grinder, the motor is controlled by an electric appliance controller, the motor is connected with a rotating stator, the rotating stator is arranged in the wet grinder, the rotating stator is provided with a rotating stator grinding plate, and the top part of the wet grinder is connected with the bottom part of the circulating pipe. The cement wet grinder disclosed by the invention has the advantages that the shearing is high-speed, the smashing and the mixing are complete, the device stability is good, the permeability is strong, the design is reasonable, the operation is convenient, the energy consumption is low, and the benefit is high.

Description

technical field [0001] The invention relates to wet crushing and grinding equipment, in particular to a cement wet grinder. Background technique [0002] The geometric size of grouting cement particles is one of the main factors affecting the pouring ability of cement grouting materials. The ultra-fine grinding of grouting cement aims to reduce the particle size of cement particles so that it can be poured into rock masses with finer cracks, improve the groutability and durability of cement slurry materials, and overcome the common cement slurry materials after solidification. The defect of volume shrinkage improves the mechanical properties of the pulp material. [0003] The preparation of grouting cement is divided into two types: dry method and wet method: the preparation and processing of dry method ultrafine cement consumes a lot of energy and costs, and has special requirements in packaging, storage and transportation, and is prone to moisture, caking, and Deteriorat...
