100,000 TPY Marble Grinding Production Line in Yunnan

Project Overview

Yunnan is rich in marble resources, and the customer owns a mine. To increase the added value of marble products, the customer selected the complete set of GK1850 Raymond Mill equipment from Guilin Mining Machinery to process marble raw materials into 250-mesh powder. The whole production line features a well-designed process with fully sealed and automated operation covering crushing, grinding, classification, collection and dust removal. The output is steadily maintained at 15~20 tons per hour. The finished powder has high whiteness and uniform particle size, fully meeting the quality requirements of industries such as plastics and coatings.

Project Details

Jaw crusher crushes raw marble ore to a uniform particle size of ≤30mm. The material is vertically conveyed by elevator to the hopper for buffering, and then fed into the GK1850 Raymond Mill for grinding and crushing via belt conveyor. Marble features moderate hardness and good grindability, which effectively reduces grinding energy consumption. The ground marble powder enters the classifier for precise sorting along with airflow. Coarse powder failing to reach 250-mesh fineness falls back into the grinding chamber for re-grinding, forming a closed-circuit processing system.

Qualified fine marble powder is hermetically conveyed through air slides to the cyclone powder collector for powder collection. The dust-laden tail gas is then sent to the pulse baghouse dust collector for deep recovery and purification treatment.

Project Advantages

High Efficiency & Stability: The GK1850 Raymond Mill adopts advanced design with a single-unit output of 15~20t/h. The system runs smoothly with stable and efficient performance.

Energy-saving & Cost-effective: Optimized for marble’s moderate hardness and good grindability, the system achieves power consumption significantly lower than the industry average.

Superior Quality: The finished marble powder boasts uniform particle size distribution, excellent whiteness and high purity.

Eco-friendly & Green: The high-efficiency two-stage dust collection combination of cyclone powder collector + pulse baghouse dust collector delivers high dust collection efficiency, with exhaust emission concentration far below national standards.
