100,000 TPY Limestone Grinding Production Line in Sichuan

Project Overview

In response to the green and intelligent upgrading policies of the building materials industry, a large building materials enterprise in Sichuan launched a technical transformation of a 100,000-tpy limestone powder production line. After comprehensive comparison and screening, GK1850 Raymond Mill from Guilin Mining Machinery was selected. It successfully processes limestone raw materials into high-quality 325-mesh powder with a passing rate ≥97%, at a capacity of 15t/h, delivering outstanding performance in energy consumption and environmental protection.

Project Details

Limestone stored in the buffer silo is fed into the GK1850 Raymond Mill for grinding and crushing by the feeder. Given limestone’s hard texture and high abrasiveness, core grinding components such as grinding rollers and grinding rings of the Raymond Mill are made of high-wear-resistant alloy materials. By increasing the rotating speed of the classifier impeller, only limestone powder meeting the 325-mesh fineness can pass through the classification zone and enter the cyclone collector for gas-solid separation.

The separated and collected finished limestone powder is then gathered by fully sealed screw conveyors and vertically conveyed to the finished product silo via elevators.

Project Advantages

Stable & Efficient: The GK1850 Raymond Mill used in this project achieves a single-unit output of up to 15t/h, easily hitting the annual target of 100,000 tons.

Energy Saving & Consumption Reduction: The core components feature great wear resistance and durability with low failure rates, greatly cutting maintenance and operating costs. Energy consumption is reduced by about 30% compared with traditional ball mills.

Superior Environmental Performance: The whole system runs under negative pressure and is equipped with high-efficiency two-stage dust removal, keeping the production site clean and dust-free.

High-Quality Finished Product: High classification accuracy ensures uniform and stable particle size distribution of finished limestone powder (325-mesh passing rate ≥97%).
