Energy-saving crusher for cement preparation and production

Abstract

The invention discloses an energy-saving crusher for cement preparation and production. The energy-saving crusher comprises a box body and brackets mounted at the two ends of the lower portion of the box body; a secondary crushing device is arranged on the lower portion of the box body; and a reciprocating type extrusion crushing device is arranged in the box body and provided with an electric hammering type crushing cone device. According to the energy-saving crusher, through angle adjustment of two extrusion crushing plates, the energy-saving crusher can crush large raw materials; through application of a hammering sleeve, in the raw material crushing process of a crushing cone, a hammering piston can hammer a crushing cone mounting seat in a reciprocating mode through the action of air pressure, and thus the crushing efficiency is improved; meanwhile, the situation that the raw materials are directly subjected to high-strength extrusion can be avoided, thus the stress degree of the energy-saving crusher is decreased, and the situation that the energy-saving crusher is damaged due to excessive stress is avoided; and through secondary crushing of the raw materials, small raw materials can be completely crushed, thus the crushing effect of the energy-saving crusher is improved.

Description

technical field [0001] The invention relates to the field of equipment related to cement production and processing, in particular to an energy-saving crusher for cement production. Background technique [0002] With the vigorous development of the construction industry, it has greatly promoted the development of the building materials market. There are many kinds of building materials, but cement has always been the most basic and important building material. There are special production lines for the production and processing of cement. The cement production line is a cement equipment production line composed of a series of equipment for producing cement. It is mainly composed of crushing and pre-homogenization, raw material preparation and homogenization, preheating decomposition, cement clinker firing, cement grinding and packaging. The Portland cement production process is typical in cement production equipment. Limestone and clay are used as the main raw materials. Af...

Problems solved by technology

[0003] In the process of cement production and processing, although the existing crushers can effectively crush the cement raw materials, because the crushing method is to crush the raw materials through the crushing machine's own strength, although this method can crush the cement raw materials. Crushing, but because the device is often subjected to excessive force during the crushing process, it is easy to cause damage to the crusher itself and affect the service life of the device
