Parameter Study Of 2500t/h New Mine Double-toothed Crusher

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. The mobile crushing station began to be used in Chinese large- scale open- pit coal mine in the 1990s. Its main machine refer to the single - toothed feed- type crusher developed by AUBEMA Company, Germany .Its crushing performance can only meet the crushing requirements for the coal and the softer delamination so that the application is restricted and the mine application requirements can not be met. The new high - efficiency and energy saving double- toothed crusher developed by MMD, USA 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 .As a result, it has been used widely in the large- scale coal mine, metal mine, non- metal mine, cement plant, quarry and coal preparation plant overseas. It is a high- efficiency crushing equipment with a broad developing future.This article gives a general description of the principle and structure of the new double- toothed crusher. A small- scale double- toothed crusher experimental bench is developed based on the similarity theory and similarity principle relationship following the development of the 2500t/h new double - toothed crusher. Based on the Bound Power theory, the relationship between the crusher parameters and the different materials and the relationship between parameters have been tested and studied through the crushing test of different materials, providing an important reference for the development of the 2500t/h new double-toothed crusher. It is also of great significance to develop a new series of double-toothed crusher product, fill in the gaps of domestic market, substitute imported product, meet needs for the large- scale mine and expand its application fields. Itprobes a systematical way of developing the new large- scale mining machinery.
