With the development trend of Chinese coal and metal mine towards the upsizing, the half continuous mining technology featuring a large-scale crushing station as the key equipment has been used widely. Considering the main machine of the large-scale crushing station always depend on products from the developed countries such as European counties and USA, it is imperative to develop a new high-efficiency and energy saving crushing equipment to substitute imported equipment and meet the needs for the domestic large-scale mine.
This article gives a general description of the principle and structure of 4000t1h differential classification toothed roll crusher .When the traditional crushers material , it depends on the impact pressure which the working parts move to impose on the cracking material , the efficiency is low , energy consumption is high and weight is heavy . These disadvantages limit the improvement of its breaking ability. In order to improve the breaking ability of the crusher, a differential classification toothed roll crusher is studied and developed, and the operating principle, structure and technique characteristics are introduced.
The mobile crushing station began to be used in Chinese large- scale open- pit coalmine in the 1990s. Its crushing performance can only meet the crushing requirements for the coal and the softer declaim nation so that the application is restricted and the mine application requirements can not be met .The new high-efficiency and energy saving differential classification toothed roll crusher developed by this article, features high capacity, high crushing hardness, high crushing ratio uniform discharge grain-size and a small amount of over- crushing because of its unique structural advantages .While, the crusher have the breaking ability of classification . As a result, it is a high-efficiency crushing equipment with a broad developing future.
