Spreader is one of the complete sets of equipment for continuous or semi-continuous mining process in large open-pit mine. It is used for satisfying the overburdening process requirements in large open pit mines. It works with the crushing system and belt conveyor. It can complete the topsoil overburdening in large open-pit coal fields, iron ores and non-ferrous metal mines, and stacking materials efficiently and orderly. The spreader can be divided into two types: Upper counterweight-arm and Lower counterweight-arm.

Specification:

The spreaders are from 2000t/h to 18000t/h, which can be customized according to different demands of users.

Application

The spreader works at the end of a semi-continuous mining system in large open pit mine for transporting and scraping materials. It works cooperatively with the discharging cars: the discharging car lift and transfer the material to the receiving belt of the spreader and then the spreader discharges the material orderly through the discharging arm. The spreader and the discharging car are interlocked to complete the spreading action and it moves along with the movement of the dumping site.

Features

01. High reliability, using discrete element analysis software to optimize the material flow at the transfer point. The material has little impact on the belt as well as on the rollers. Belt conveyor does not scatter or off tracking. The large welded structural is wholly annealed to effectively release the residual stress.

02. Continuous operation, high productivity and low cost; the drive motor of the discharge and receiving belt have variable frequency speed control, and grounding pressure propel device is adapted to the harsh working conditions at dumping site.

03. With startup self-test function, monitoring system can display the operation status of the spreader as well as fault content, fault location, etc. in real time; the discharging arm can automatically raise/lower, preventing collision and reducing dust; the control system automatically ensures the spreader and discharging car work coordinately.

04. Adapted to the complex and varied working environment such as plateau, low temperature, heavy load, impact, high wind and dust; the high load bearing and low running speed of the belt can be adjusted according to the size of the conveying amount, and the energy saving effect is obvious. The spreader is equipped with a dust suppression system to meet environmental protection requirements.
