Technical features

1. The whole machine is compact in structure, reasonable in arrangement, adjustable in height and width, and has strong adaptability to coal seam and roadway;

2. The structure of the crusher adopts double protection of shear pins and speed sensors, which is safe and reliable; The crushing block degree can be adjusted; The optimized arrangement of cutting pick improves the crushing capacity and reduces the specific energy consumption; Cutting pick adopts hardening treatment technology to prolong the service life;

3. The conveying mechanism adopts sleeve roller chain traction, which reduces the height of the machine body, and is easy to disassemble and assemble;Hydraulic motor drive can realize no-load start;

4. Travelling mechanism adopts track traveling mechanism, which is driven by hydraulic motor and has large traction.

5. The conveying system and track travelling mechanism adopt secondary planetary gear reducer, which has large transmission ratio, small volume and high transmission effciency.

6. The lubricating grease cylinder is used for conveyor chain and track tensioning, and the operation is easy, safe and reliable;

7. The electrical system adopts the programmable logic controller (PLC) as the main controller, and the system is safe, reliable and easy to maintain.

PZL460 series feeder crusher is suitable o-short-wall mechanized coal mining and fast tunneling.

The Room&Pillar mining of continuous miner is divided into two processes according to the different supporting transportation equipment. One is continuous transport + belt conveyor, and the other is coal conveyor (or shuttle)+feeder crusher + belt conveyor. The second process is suitable for medium stable roof; The floor is required to be stable, flat and free of water, with a slope of less than6 degrees near the horizontal coal seam, and the width of the roadway is required to be greater than 4 meters.
