Green Intelligent Manufacturing, Precision Grinding | Liming Heavy Industry MW Micro Powder Mill Supports Smooth Commissioning of GCC Powder Project

Russia boasts abundant calcium carbonate resources. It has ample reserves of calcite, limestone and dolomite with high purity ore bodies, making it a high quality raw material base for producing high grade ground calcium carbonate (GCC) powder. With the continuous upgrading of downstream industries such as coatings, plastics and paper making, the market has raised stricter requirements for GCC products. Multiple indicators including whiteness, particle size distribution, specific surface area, oil absorption, particle morphology and impurity content directly determine the application performance of powder in end products.

To meet the demand for industrial upgrading of the regional calcium carbonate sector, Liming Heavy Industry has entered into an in depth strategic cooperation with a leading local enterprise in the coatings industry to jointly build a large scale high end GCC micro powder grinding project. Adopting Liming Heavy Industry MW Micro Powder Mill as the core equipment, the project builds a modern grinding production line integrating precision pulverization, intelligent management & control and green production, setting a new benchmark for the high quality development of the regional GCC industry.

Recently, a large scale ground calcium carbonate (GCC) grinding production line undertaken by Liming Heavy Industry has successfully completed commissioning and gone into full scale operation. Two sets of MW Micro Powder Mills form the core grinding system of the project. The whole production line features well planned layout and smooth flowing technological processes. After multiple rounds of rigorous investigation and comparison from preliminary scheme demonstration to equipment selection, the customer finally chose Liming Heavy Industry. The successful commissioning of this project provides strong support for the local green building-materials industrial cluster.

Processed Material: Ground Calcium Carbonate

Equipment Deployed: 2 sets of Liming Heavy Industry MW Micro Powder Mill

Core Advantages of Ground Calcium Carbonate Project

Rational Layout for Intensive & High-efficiency Operation

The production line adopts a well planned spatial layout based on material properties and technological processes to optimize material conveying routes. All working procedures are closely connected to support long term continuous and stable equipment operation, meeting the production demands for large scale ultra fine ground calcium carbonate.

Intelligent Control for Precision and Reliability

The project is equipped with an integrated intelligent PLC electrical control system, which centrally collects and dynamically feeds back full process parameters including main unit operating status, feeding frequency, air volume adjustment and finished product fineness. The system coordinately adjusts the operation rhythm of each procedure via programs, effectively reducing quality deviations caused by manual intervention and realizing standardized and refined control over the whole powder production workflow.

Robust Equipment to Guarantee Product Quality

Liming Heavy Industry MW Micro Powder Mill delivers durable and stable performance with long service life core wear resistant parts. Fitted with a new high efficiency cage type classifier, it can stably produce finished powder with D97 ≤5 μm in one pass. It is suitable for ultra fine grinding of minerals with Mohs hardness below 7 and moisture content under 6%, such as calcite, limestone, marble, ground calcium carbonate, quicklime, talc, dolomite, barite, mica, graphite, petroleum coke and carbon black. It serves as ideal processing equipment for deep mineral processing.

Low Investment & Operating Cost with Short Payback Period

At the same finished product fineness, compared with traditional jet mills, this model features lower capital investment, simpler system workflow and reduced operating costs.

Reliable Structure & Convenient Maintenance

There are no rolling bearings or screws inside the ring grinding chamber, which avoids equipment damage caused by vulnerable bearings or loose screws. Key components are made of high quality wear-resistant materials for long service life, greatly reducing downtime for maintenance and spare part replacement costs.

Energy saving & High efficiency, Premium quality End products

Thanks to the optimally designed roller path curve integrated with the air swept dry type system, specific energy consumption is significantly reduced. Adopting the material layer grinding principle, the equipment can stably achieve finished product fineness of D97 ≤5 μm in a single pass, meeting stringent requirements for ultra fine powder from high end coatings, plastics, paper making and other industries.

Eco friendly with Compliant Environmental Performance

Fitted with pulse dust collectors, together with silencers and sound insulation houses, the equipment effectively controls dust emission and noise pollution, complying with environmental protection standards for modern green factories.

The successful commissioning of this GCC grinding project marks another practical practice of Liming Heavy Industry empowering the upgrading of the non metallic mineral industry with ultra fine grinding technology. Going forward, Liming Heavy Industry will keep focusing on the R&D of intelligent and low carbon powder processing equipment, and continuously iterate complete solutions for deep processing of non metallic minerals. We help calcium carbonate enterprises tap into added value of resources, and promote the steady transformation of regional resource advantages into industrial and market advantages.
