Open-cut mining machine and machine for testing cutting workability of critical mined material

摘要

The device has a two-track running gear (1), a frame (2) with a drive assembly (3) and a control platform (4). A cutting roller that be raised and lowered is arranged in front of the running gear, to roll about a horizontal axis perpendicular to the driving direction. The cutting roller extends the width of the device, is connected to a conveyor and is equipped with cutting tools, guide plates and delivery plates. The total mass, drive power and throughput power of the test device are a given ratio less than the mining power of a mining device of the same speed and force of cutting tool. The roller rotation speed and advance speed are continuously variable to optimize the extraction rate.
