Grinding Equipment
Grinding Equipment refers to Mining Grinding Ore Mills. These grinding mills machine are used in the third stage of ore processing. This stage occurs after crushing and screening in mining operations. The equipment is crucial for coarse grinding, milling, and refining ores, for coarse grinding, milling, and refining of ores. Crushing breaks large ore pieces into defined sizes, whereas grinding further reduces the size of the ore to produce powdery raw materials for final products or specific stages of manufacturing processes. For example, reducing sizes to liberate desired minerals from gangue and presenting ores in a form with a large surface area for leaching agents.
Types of grinding equipment
Grinding can be performed in dry or wet conditions, with wet grinding generally preferred due to lower power consumption and higher mill capacity. However, dry grinding is chosen when wet grinding risks altering the physical or chemical structure of the material, or when a higher proportion of fine powder is required without using water due to processing constraints in ore processing. Depending on their principles and application scenarios, our range of grinding mills includes ball mills, rod mills, wet mills, Raymond mills, vertical mills, vibrating mills, planetary ball mills, hammer mills, jet mills, centrifugal mills, roller mills, high-pressure roller mills, and airflow mills. These machines use different mechanical actions such as impact, compression, friction, and vibration to process materials into the desired particle size, ultimately refining ores into specified products. The selection of appropriate grinding equipment is typically determined by feed size and the required product size.
Energy-saving Grate Ball Mill
Wet type, rolling bearing
Capacity: 160t/h
Application: Commonly used for grinding coarse-grained ores.
The wet energy-saving grate ball mill utilizes groove-type circular lining plates, which increase the contact surface between balls and ores, enhancing the grinding effect and improving ore lift capability, thus reducing energy consumption.
Wet Type Rod Mill
Wet type, with steel rods as the grinding medium.
Capacity: 0.62～250t/h
Application: Rod mills are primarily used for coarse grinding operations. They are suitable for the fine crushing and coarse grinding of ores in the first stage of open-circuit grinding, particularly suitable for handling brittle materials.
Wet rod mills are available in three types: overflow rod mills, peripheral discharge rod mills, and center-periphery discharge rod mills, catering to various customer requirements.
Grid Ball Mill
Wet type, a traditional design with forced discharge through a grid.
Capacity: 900mm ~ 4500mm
Application: This wet grid ball mill is commonly used for grinding coarse ores.
Features: The lifting device uses a self-developed hydraulic lifting system. During maintenance, the hydraulic jack can be raised and lowered by simply operating the hydraulic station handle, with a lifting height of up to 400mm. Compared to ordinary lifting devices, it is easier to operate, more convenient and quick, and has lower maintenance costs.
Overflow Type Ball Mill
Wet type, relies on the slurry’s natural overflow for discharge.
Capacity: 0.17 ~ 170t/h
Application: This type of wet overflow ball mill is commonly used for grinding fine ores.
Features: The wet overflow type ball mill includes a slow transmission system. When the ball mill starts, the low-speed slow drive operates first, followed by the high-speed main motor drive system, saving energy and reducing the impact on the ball mill equipment and power grid system.
Autogenous Mill
Wet type, utilizes the ore itself as the grinding medium.
Capacity: 200-350mm
Application: This autogenous mill is generally used for rough grinding after coarse crushing.
Features: The efficient autogenous mill can achieve the functions of secondary and tertiary crushing and screening, or partial or complete grinding functions of a ball mill.
Cylindrical Ball Mill
A high-efficiency, energy-saving overflow type using rolling bearings.
Capacity: 160t/h
Application: The cylindrical ball mill is commonly used for grinding fine ores.
Features: The cylindrical overflow ball mill uses rolling bearings instead of sliding bearings for transmission, significantly reducing friction, making it easy to start, and saving 20-30% energy.
Raymond Mill
A complete system capable of forming an independent production line.
Capacity: 3-22T/h
Application: Suitable for grinding non-flammable and non-explosive mineral materials with a Mohs hardness below 9.3 and humidity below 6%. This includes cement (clinker), talc, feldspar, quartz, slag, mica, calcite, limestone, barite, potassium sulfate, bentonite, and over a thousand other materials.
Dry Ball Mill
A ball mill device for processing dry materials.
Capacity: 0.25-100t/h
Application: Used in the mining, building materials, metallurgy, and chemical industries, primarily for processing metallic ores.
Features: A horizontal cylindrical rotating device, outer gear transmission, two bins, and a grid type ball mill.
Dry Rod Mill
A dry rod mill device with fine discharge particle size.
Capacity: 64-180t/h
Application: Mainly used in mining and chemical industries.
Features: A rod mill developed to international technical standards, with a simple structure and strong production capacity, especially suitable for handling fine-grained materials.
