Coal Shearers
Overview
The coal shearer is the core equipment of a fully mechanized longwall face, enabling continuous mechanized coal cutting. Our shearers suit thin, medium and thick seams, with a cutting height range of 0.8-6.5 m and installed power of 200-3000 kW, and can form the three-machine set together with hydraulic supports and scraper conveyors.
Features
- Multi-motor transverse layout: compact structure with ample maintenance space
- Memory cutting system: automatically records seam undulation and plans the cutting path
- Variable-frequency haulage drive: high traction force with adjustable speed
- Drum picks made of cemented carbide, improving wear resistance by 50%
Applications
Longwall fully mechanized coal cutting, automated thin-seam mining, steeply inclined seam mining, and top-coal caving mining.
Key Advantages
High cutting efficiency and good lump coal rate; high automation reduces manual intervention; complete spare-parts supply system with key parts in stock.
