Manganese Ore Crushing
Manganese is widely distributed in nature, and most ores and silicate rocks contain manganese. Among them, pyrolusite and psilomelane have high economic value, and the manganese content in the minerals can reach about 50-70%, which is an important industrial mineral of manganese. In addition, there are manganese ore, brown manganese ore, black manganese ore, rhodochrosite, etc.
Dahongli Machinery-focuses on various types of ore crushing and provides you with solutions for manganese ore crushing. At the same time, we provide perfect technical support and after-sales service. According to the different characteristics of manganese ore raw materials, we will design crushing solutions according to the specific conditions of customers to meet the crushing and processing of different ores. Conventional manganese ore crushing production lines are basically divided into: crushing section, grinding section, sorting section, and drying section.
Manganese ore crushing production line
Manganese is widely distributed in nature, and most ores and silicate rocks contain manganese. Among them, pyrolusite and psilomelane have high economic value, and the manganese content in the minerals can reach about 50-70%, which is an important industrial mineral of manganese. There are also hydromanganese ore, brown manganese ore, black manganese ore, rhodochrosite, etc.
According to the characteristics of manganese ore, Chengdu Dahongli Machinery has launched a set of ore crushing production line, which is mainly composed of: jaw crusher + cone crusher + high-efficiency impact crusher + circular vibrating screen + high-pressure roller mill. Auxiliary equipment can be added according to the specific needs of customers: magnetic separator, dryer, dust removal equipment, feeding system, dust collection device, etc.
Process description:
1. Crushing section
The vibrating feeder feeds the gold ore raw material into the jaw crusher for crushing; the crushed material is sent to the cone crusher (coarse crushing) by the conveyor belt for crushing, and is transported to the vibrating sorting screen by the belt conveyor for screening. The stone that meets the particle size is then sent to the cone crusher (fine crushing) for secondary crushing, and the unsatisfactory material is returned to the cone crusher (coarse crushing) through the conveyor belt for re-crushing; the material coming out of the fine crushing cone crusher is also screened by the vibrating sorting screen, and the unsatisfactory material needs to be returned to the fine crushing cone crusher through the conveyor for re-crushing; the satisfactory material is sent to the high-pressure roller mill through the conveyor for grinding and crushing.
2. Grinding section
The manganese ore material after the crushing section enters the ball mill for re-grinding, which has met the material requirements of the subsequent process. The ball mill is usually combined with the classifier to form a grinding and classifying unit for operation. The ball mill grinds the processed material, and the classifier divides the grinding product into qualified material and unqualified material. Unqualified products are returned to the ball mill for re-grinding to improve the grinding process. The grinding operation of the classifier and the returned sand after classification constitutes a closed grinding section. The classification operation can be pre-classification, inspection classification, control classification or both classification operations.
3. Magnetic separation section
The ground manganese ore powder enters the magnetic separator for sorting. The separation section usually adopts a combination of strong magnetic separation and weak magnetic separation.
4. Drying section
The manganese powder after flotation is sent to the dryer. The drying process in the mineral processing process is mainly to remove the moisture content of the selected manganese powder.
