Strength Witness | 6 Sets of Liming Heavy Industry MTW European Trapezium Mills Operating Efficiently in the Ground Calcium Carbonate Powder Production Project

Nanzhao County, Henan Province, boasts abundant calcium carbonate resources with a total reserve of 1 billion tons, making it the largest calcium carbonate production base in central China. Leveraging its rich calcium carbonate resources, the county is committed to building the urban brands of "Calcium Capital of the Central Plains" and "Capital of Waterborne Coatings in China". Relying on its core advantages in the manufacturing of grinding equipment, Liming Heavy Industry has reached in-depth strategic cooperation with leading enterprises in the coating industry to jointly build a large-scale ground calcium carbonate powder production project with an annual output of 500,000 tons.

Extending the "Income Growth Chain" of Ground Calcium Carbonate

This ground calcium carbonate powder production line consists of 6 sets of MTW European trapezium mills from Liming Heavy Industry. The entire site presents an imposing scene, with an annual output of up to 500,000 tons, becoming a model of a benchmark factory featuring digital intelligence, green development and environmental friendliness in the local coating industry.

Material: Calcite

Equipment: 6 sets of Liming Heavy Industry MTW European Trapezium Mills

Capacity: 500,000 tons

Liming Heavy Industry always puts customers' interests first, maintains professionalism and rigor throughout, and adopts an innovative and practical development model to scientifically plan the site of the Nanzhao ground calcium carbonate powder production line. With a compact structure, green and environmentally friendly production, and highly efficient operation, the project has won high recognition from customers. It has enhanced the reputation of the local green building materials industry, expanded the industrial cluster, and injected strong impetus into the high-quality economic development of the region.

Strength in Grinding: "Superior Technology"

The core equipment of this project is the MTW European trapezium grinding mill, which incorporates multiple new patented technologies such as integral bevel gear transmission, internal thin-oil lubrication system, and curved air ducts. It features high grinding efficiency and large output, and is equipped with a pulse dust collector, meeting national environmental protection standards. The finished powder has uniform particle size and high purity, meeting the requirements of high-end coatings.

After the raw material of ground calcium carbonate is cleaned to remove impurities and pre-crushed, it is uniformly and continuously fed into the grinding chamber of the main mill via a variable-frequency belt feeder for grinding. The ground material is conveyed by the airflow generated by the fan to the classifier for sizing. Under the action of the analyzer, the material that does not meet the fineness requirement falls back into the grinding chamber for regrinding, while the qualified material flows with the airflow through the pipeline into the cyclone powder collector for separation and collection. The product is then discharged through the discharging device. The separated airflow returns to the fan through the return air duct at the upper end of the cyclone powder collector. This production system operates under negative pressure in a sealed environment and is equipped with a pulse dust collector to prevent dust leakage, fully complying with national environmental protection standards.

Escorting the Project "Full Cycle"

Liming Heavy Industry provides customers with EPC general contracting services for ground calcium carbonate projects, offering one-stop services throughout the entire process, from project planning and design, equipment selection and configuration, to installation, commissioning, and post-operation maintenance. Relying on its rich project experience in the field of grinding equipment manufacturing, it has promoted the efficient implementation of the large-scale ground calcium carbonate powder production project with an annual output of 500,000 tons, creating a high-standard and high-efficiency ground calcium carbonate powder production line for customers, and achieving multiple optimizations in project construction cycle and operation cost.

Green mountains and clear waters hide rich mineral resources; dual benefits (economic and ecological) soar to compose a green chapter! The strong alliance between Liming Heavy Industry and leading coating enterprises has set a new benchmark in the field of ground calcium carbonate grinding and processing, where efficient production and ecological protection go hand in hand.

This is an era where demand and innovation go hand in hand. The demand iteration and technological innovation in the calcium powder market are advancing at a rapid pace with each passing day. As a pioneer in the field of grinding equipment manufacturing, Liming Heavy Industry has always focused on continuously improving the performance and quality of grinding mills. With advanced powder production technology and efficient production capacity, it provides calcium powder partners with more cutting-edge and reliable grinding solutions, continuously promoting the high-end calcium carbonate industry to develop to a higher level and broader fields.
