Introduction of Product-Introduction of Mobile Crusher BR580JG-1 A new mobile crusher series “BR580JG” has been sold that completely innovates the specification of the former BR550JG of the 50-ton class in a full model change for crushing and reuse of construction by-products produced at sites in civil engineering works and demolition works and for primary crushing at quarries and mines. The new product is overviewed and its features are introduced.68728

Key Words: Mobile crusher, jaw crusher, Tier3, automatic adjustment mechanism for crusher outlet clearance, crusher protection mechanism, KOMTRAX

1. Introduction

    The technique to dispose and recycle concrete waste that is generated in demolition works, as well as construction by-products that are generated in civil engineering works at work sites such as natural stones and rocks, using mobile crushers is greatly effective in lowering work costs and in solving disposal site problems and social problems including traffic congestion caused by waste carrying vehicles.

    In quarries and mines, primary crushing is performed in mines and quarrying sites and crushed waste is transported to stationary plants for secondary crushing, or secondary crushing machines are also installed at mining and quarrying sites to produce products. This technique can also lower the crushed rock production cost.

    This technique has been used in Europe as a routine method from early on and many manufacturers of mobile crushers are competing with each other in the market. This trend is gradually spreading to the world including the North America and Japan.

    Since the introduction of its first-generation Galapagos model BR60 in the market in 1992, Komatsu has refined the product and expanded the product series. Komatsu decided to manufacture equipped crushers in its 30t-class BR380JG series sold in 2003 in house. The construction and functions of the crusher were completely changed. As a result, the development concept of this series has won a high evaluation in the market and sale of the series is on a high level.

Targeting the North American and European markets especially, the high-end model BR550JG has undergone a model change, including in-house manufacture of the crusher and incorporation of product features of the same concept as those of the BR380JG in the series. The new version of the BR550JG is now sold as “BR580JG” after the model change, as outlined in the following .

2. Objective of Development

     In starting the development of BR580JG, the following implementation items were set for it incorporating functional enhancement following the development concept of BR380JG with a focus on “Safety,” “IT” and “Environment,” which are the corporate brand concepts of Komatsu .

     The configuration requirements of BR580JG and flow of crushed materials are described below.

     Raw materials (concrete waste material, stones, rocks and other materials) charged into the hopper are fed into the crusher through the vibration of a grizzly feeder and are crush-ed to a size according to the outlet clearance that is set in advance and are ejected to the outside of the crusher by a belt conveyor underneath.

     Sand, earth, pebbles and other materials in fed raw materials are separated by grizzly bars and are dropped onto the belt conveyor after passing through the sliding chute.

     By operating the change-over plate inside the sliding chute, selection can be made whether to move out by mixing with crushed products by the belt conveyor or to eject after separation (side conveyor is selected as an option),

     If reinforcements or other materials are mixed in fed raw materials, these materials are ejected to one side of the machine body by using magnetic separator (option), allowing separation from products after crushing . 移动破碎英文文献和中文翻译:http://www.751com.cn/fanyi/lunwen_77374.html
