ZSJ-75Gwire saw machine used for quarrying in a strip mine is a new breakthrough of the quarrying technology in China. The machine, which is controlled by a most advanced frequency converter made in Japan, realizes full automatic cutting, high cutting speed, and safe and simple operation. The machine can not only fundamentally remove the danger of the operation staff posed by the blasting operation, but also reduce the labor intensity of the operation staff, avoid dust and noise pollution caused by flame cutting and blasting, improve the resource utilization level, and reduce chat discharge as well as the mining cost.
1. Electrically driven left-and-right movement for the main flywheel of the wire saw
2 Electrically driven 360-degreee rotation
3 Constant tension control system adopted, automatic control on the cutting process through double frequency converters, persistently stable and unchanged tension of the beaded wire;
4. Switchover between manual operation and automatic operation, unmanned operation during the automatic operation of the device, operating several devices by one man at the same time
5. Imported vector frequency converter, constant output torque, real-time display of parameters like the main motor cutting current, main flywheel speed and walk speed by the control console
6. Electrically driven right-and-left movement and rotation of the power unit, limit protection set.
