The YGM130 high-pressure grinding mill is a high-efficiency grinding device, an innovation based on the traditional Raymond mill. By enhancing the pressure-applying capacity of the grinding roller assembly, it increases the grinding force exerted by the grinding rollers by 1.2 times, achieving higher output and finer grinding accuracy at the same power. It is particularly suitable for a large number of non-metallic minerals with a Mohs hardness below 9.3.

Core Working Principle

The YGM130's operating principle can be summarized as "multi-layer grinding, efficient grading."

1. Feeding and Grinding: After initial crushing in the jaw crusher, the material is conveyed by an elevator to the storage silo, and then evenly fed into the main grinding chamber via a feeder. Centrifugal force causes the grinding rollers to swing outward, pressing firmly against the grinding rings.

2. High-Pressure Compaction: The core of this process lies in the device's built-in high-pressure spring mechanism. As the grinding rollers compress the material, the springs provide continuous, stable, and intense pressure, firmly compacting the material against the grinding rings for efficient crushing. 

3. Analyzer Screening: The crushed powder is lifted by the fan airflow and sent to the analyzer at the top. Unacceptable coarse powder is returned to the analyzer blades for re-grinding, while acceptable fine powder is carried by the airflow into the cyclone collector and ultimately collected as the finished product.

This design ensures a uniform, fine particle size and a high screening rate in the finished product.
