With the development of industry, the demand for calcium carbonate products is increasing, and the demand for calcium carbonate grinding is also increasing. Large-scale production equipment needs advanced equipment to support. Traditional equipment can also be produced, but the production cycle is longer and the energy consumption is higher. Vertical mill is a relatively advanced grinding equipment at present. It has advanced technology, low energy consumption, floor area, and high efficiency.

Calcium carbonate ((CaCO₃)) is an inorganic compound, commonly known as limestone, limestone, limestone powder, marble and so on. Calcium carbonate is neutral, insoluble in water and hydrochloric acid. It is one of the most common materials on earth. It exists in aragonite, calcite, chalk, limestone, marble, limestone and other rocks. It is also the main component of an animal skeleton or shell. Calcium carbonate is also an important building material, which is widely used in the industry.

Under the situation that the technical advantages of vertical mill products are increasingly prominent, Tongli Heavy Machine actively absorbs the foreign successful experience, and through the continuous technological innovation and upgrading of the team, has launched vertical mill products with independent intellectual property rights. This equipment integrates crushing, drying, grinding, flour separation and transportation as one of the system solutions, focusing on three areas of non-metallic ore, coal powder, and slag. It is a large-scale non-metallic ore flour optimization equipment. Calcium carbonate powder processing is generally divided into four types: crude calcium carbonate powder processing (0-3mm), fine powder processing (20 mesh-400 mesh), ultra-fine calcium carbonate powder deep processing (400 mesh-1250 mesh) and micro-powder processing (1250 mesh-3250 mesh). The processing usually goes through four stages: crushing, grinding, grading and flour collection.

Vertical grinding mill is the best choice for industrial pulverizing. Because it integrates crushing, drying, grinding and grading transportation, has a simple system, compact layout, occupies about 50% of the area of the ball milling system, and has low energy consumption. Compared with the ball milling system, it can save 30% - 40% of the energy consumption, so it can greatly reduce investment costs and improve economic benefits. In addition, due to the short residence time of materials in grinding, it is easy to detect and control the product size and chemical composition, reduce repeated grinding, stabilize product quality, and realize product quality upgrading. In the process of operation, the equipment has small vibration, low noise, and the whole equipment is sealed. The system works under negative pressure, and the environment is clean, which meets the current environmental protection requirements.

As national powder R&D center, GUIKUANG has made much efforts and contributions for the development of powder industry more than 40 years. It is an expert grinding mill manufacturer.
