Grinding device for cement production

Abstract

The invention belongs to the field of cement production, and particularly relates to a grinding device for cement production. The device comprises a box body, wherein the upper end of the box body is connected with a box cover through threads, the left side of the exterior of the box body is fixedly connected with a left supporting plate, the upper end of the left supporting plate is fixedly connected with a supporting seat, a through hole is formed in the supporting seat, a threaded rod is rotationally connected into the through hole, a moving frame is connected to the outer side of the threaded rod through threads, a material conveying barrel is fixedly connected to the upper end of the moving frame, a barrel cover is connected to the left end of the material conveying barrel through threads, a feeding hopper is fixedly connected to the upper end of the material conveying barrel, and a first motor is fixedly installed at the left end of the barrel cover. According to the device, the material conveying barrel, a spiral, the first motor, a die head and other parts are designed to form a conveying mechanism, a driving bevel gear and a grinding head driven by a second motor are designed to grind conveyed materials, continuous grinding work can be achieved, the grinding efficiency is high, and grinding according to batches is not needed.

Description

technical field [0001] The invention relates to the technical field of cement production, in particular to a grinding device for cement production. Background technique [0002] At present, in the cement production process, it mainly involves crushing and pre-homogenization, raw meal preparation, raw meal homogenization, preheating decomposition, cement clinker firing, cement grinding, cement packaging and other processes. Among them, the preparation of raw materials includes the raw material process from the crushing of raw materials to the deployment of ingredients to meet the requirements. There are two methods of raw meal preparation: dry method and wet method. In the dry preparation process, large hard raw materials such as limestone are first crushed to a block with a size of about 100mm according to the traditional process, or crushed for a second time to a block with a size of less than 25mm (which has been developed in recent years. It can be crushed into blocks l...
