The TGM type trapezoidal mill, developed by Liming Heavy Industry, is a highly efficient and energy-saving grinding equipment designed for processing medium to fine powders in the non-metallic mineral, chemical and building materials industries. Optimized from traditional mills, it offers higher efficiency, lower energy consumption and superior operational stability, meeting the needs of large-scale industrial production.

Advantage

1. High efficiency, low power consumption
Patented trapezoidal roller technology for optimal grinding.
Advanced classification system reduces energy requirements.
2. Adjustable fineness (80-400 mesh)
Precise adjustment via the dynamic analyzer speed.
3. Stability and reliability
Reduction gear transmission + flexible coupling, minimizing vibration and noise (<75 dB).
4. Simplified maintenance
Wearing parts (rollers, ring gear) made of abrasion-resistant materials, extending service life.
Quick replacement without prolonged downtime.
5. Eco-friendly design
Built-in pulse dust collector, zero dust emissions.
Closed-circuit operation under negative pressure.

Working Principle

Feeding: Pre-ground materials are conveyed to the mill by an elevator.
Grinding: Compression and shearing between trapezoidal rollers and the grinding track.
Classification: Fine particles are separated by the turbine analyzer, while coarse particles are returned to the mill.
Collection: The fine powder is collected in the cyclone and then stored.
Quality Control: Particle size is guaranteed by dynamic adjustment.
Key Advantage: Continuous, automatic, and environmentally friendly process, ideal for modern production lines.
