Cement roller press with smooth feeding function and crushing roller cleaning function

Abstract

The invention relates to a cement roller press with a smooth feeding function and a crushing roller cleaning function. The cement roller press comprises a main body, a feeding hopper, a mounting frame, two crushing rollers and two power devices, and further comprises an extrusion mechanism and two cleaning mechanisms, wherein each cleaning mechanism comprises a supporting sleeve, a lifting rod, acleaning brush, a supporting wheel, a spring, a first knocking block and a second knocking block; and the extrusion mechanism comprises a support, a screw rod, a fixed bearing, a ball screw bearing, apressing disc, a first connecting rod, two driving assemblies, two supporting assemblies and at least two crushing teeth. According to the cement roller press with the smooth feeding function and thecrushing roller cleaning function, raw materials can be extruded through the extrusion mechanism, so that the probability of blockage of the feeding hopper is reduced, meanwhile, the grabbing effectof the crushing rollers on the raw materials is improved, and the crushing effect of the roller press on the raw materials is improved; and the raw materials adhered to the crushing rollers can be scraped off through the cleaning mechanisms, so that the practicability of the roller press is improved.

Description

technical field [0001] The invention relates to the field of cement production equipment, in particular to a cement roller press with a crushing roller cleaning function and smooth feeding. Background technique [0002] Roller press, also known as calender, roller mill, rolling mill, extrusion mill, roller press mill, is a new type of cement energy-saving grinding equipment developed in the mid-1980s in the world. It has the advantages of replacing ball mill pre-grinding with high energy consumption and low efficiency System, and the function of reducing steel consumption and noise, is suitable for new plant construction, and can also be used for technical transformation of old plants, so that the output of the ball mill system can be increased by 30-50%, and the 0.08mm fine material accounts for 20% of the extruded material cake. -35%, less than 2mm accounts for 65-85%, the internal structure of small particles is full of many tiny cracks due to extrusion, and the wearabili...

AI Technical Summary

Problems solved by technology

[0003] The roller press plays an important role in cement production. When the existing roller press is in use, the raw material is crushed by the crushing roller. Under strong pressure, the raw material is easy to adhere to the crushing roller, which reduces the Not only that, when the roller press of the prior art is in use, larger materials are difficult to be grabbed by the crushing roller, which reduces the crushing efficiency of the roller press for raw materials
