Besides briquette machine, mineral powder ball press machine is also widely used. Before using the ball press machine, there are some matters that need special attention. In particular, it is important to prepare raw materials, and ensure that the raw materials have proper moisture, uniform and good chemical composition and certain particle size, which are all prerequisites for the production of qualified pellets.

Concentrate powder should have a certain fineness, which is the basic condition to ensure the smooth pelletizing process of dry powder ball press. Generally, the finer the particle size, the larger the specific surface area of mineral powder, and the greater the molecular force between the particle surfaces, which is beneficial to pelletization. Under the condition of containing some fine particles, the particles are arranged very closely, and the hand tubule has strong effect. Therefore, the existence of ultra-fine particles in mineral powder is very important for pelletizing. Therefore, we should try our best to recover ultrafine iron minerals in mineral processing. Generally speaking, foreign pelletizing plants require that the particle size smaller than 0.044mm accounts for more than 60% of raw materials, and the particle size smaller than 0.074mm should reach more than 90%. Therefore, some imported concentrate powder can be added in the production process to improve the quality of raw materials. After adding some imported concentrate, the quality of pellets can be improved.

The ball press machine produced by our company is widely used in the fields of power generation, metallurgy, chemical industry, energy, transportation, heat supply and consumable materials. The pressed products can be customized according to customers’ requirements. The ball press has stable performance and high output, which is beneficial to energy saving, environmental protection, pollution alleviation and transportation.
