Raymond mill or Ball mill

Raymond mill and ball mill are both commonly used grinding equipment, but they have some differences in terms of their structure, working principle, and application.

Structure: The structure of Raymond mill is mainly composed of the main machine, analyzer, fan, finished cyclone separator, powder cyclone separator, and air duct. The structure of ball mill is mainly composed of a feeding port, a discharging port, a rotary part, a transmission part (reducer, small gear, motor, electric control), and other components.

Working principle: Raymond mill uses a grinding roller and grinding ring to crush and grind materials, and then the ground material is blown into the powder concentrator by the airflow of the blower and the classifier for classification. Ball mill uses the impact and grinding action of the grinding media (steel ball) to crush and grind materials.

Application: Raymond mill is mainly used for grinding non-metallic mineral materials with Mohs hardness less than 7 and humidity less than 6%, such as limestone, calcite, dolomite, talc, gypsum, barite, fluorite, zeolite, manganese ore, ilmenite, phosphate rock, bentonite, etc. Ball mill is widely used in the grinding of various ores and other materials in the mining, building materials, chemical, and other industries.

Capacity: The capacity of Raymond mill is relatively small, generally several tons per hour, while the capacity of ball mill can reach hundreds of tons per hour.

In summary, Raymond mill and ball mill have their own advantages and disadvantages, and their application fields are also different. It is necessary to select the appropriate grinding equipment according to the specific needs of the production process.

Ball mill

Ball mill is a type of grinder used to grind, blend, and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the grinding balls drop from near the top of the shell.

The basic components of a ball mill include a cylindrical shell, grinding balls (usually made of steel), and a motor that drives the mill. The shell is usually made of steel and lined with a material such as rubber or steel that protects it from wear.

The grinding balls are generally made of steel, although other materials such as ceramic, rubber, or glass may also be used. They are placed in the mill along with the material to be ground, and as the mill rotates, the grinding balls are lifted up and then dropped back down onto the material, grinding it into a fine powder.

Ball mills are commonly used in the mining, metallurgy, chemical, and building materials industries. They are used to grind a variety of materials, including ores, chemicals, ceramic raw materials, and paints.

Ball mills are widely used because they are efficient, reliable, and relatively easy to operate. They can be used for both wet and dry grinding, and can be designed to operate continuously or intermittently.

Raymond mill

Raymond mill is a common grinding equipment that is widely used in various industries such as mining, cement, and chemical industries. It is suitable for processing various non-flammable and non-explosive materials with Mohs hardness less than 9.3 and humidity less than 6%, such as limestone, calcite, activated carbon, talc, dolomite, titanium dioxide, quartz, bauxite, marble, feldspar, barite, fluorite, gypsum, ilmenite, phosphorus ore, clay, graphite, kaolin, diabase, gangue, wollastonite, etc.

The main components of Raymond mill include the main engine, analyzer, fan, finished cyclone separator, micro-powder cyclone separator, and duct. The main engine is composed of a frame, an inlet volute, a blade, a grinding roller, a grinding ring, a casing, and a motor.

The grinding process of Raymond mill is mainly achieved by the grinding roller and the grinding ring. The grinding roller rotates around the central axis, and the grinding ring rotates around the grinding roller. The material to be ground is fed into the grinding chamber through the feeding device, and is continuously and evenly ground by the grinding roller and the grinding ring. After being ground, the powder is blown by the airflow of the fan and enters the analyzer for sorting. The coarse particles are returned to the grinding chamber for re-grinding, and the fine particles are collected by the cyclone separator and discharged through the powder outlet.
