What are the types of ball mills? What are the classifications of ball mills?

There are many types of ball mills, according to the different use environment, the types of ball mills selected are also different, the types of ball mills commonly used in the mineral processing industry mainly include wet ball mills, dry ball mills, and cone ball mills, among which wet ball mills are divided into overflow ball mills and lattice ball mills; Cone ball mills have dry cone ball mills and wet cone ball mills, which are also divided into overflow and lattice.

However, according to its classification, there are several types of ball mills:

Long mill (or tube mill):Generally, the length-diameter ratio of the ball mill barrel is 4m, and there are at least 2 4 bins inside.

Medium and long mills:The length-to-diameter ratio of the ball mill barrel is 3m.

Short Mill:The length and diameter ratio of the ball mill barrel is 2m, and it is mostly a single-bin ball mill, which is used for coarse grinding or primary grinding in the concentrator, and can also be used in series.

Ball Mill:The grinding medium of the ball mill is mainly steel balls, so it is named ball mill, which is a very common equipment for concentrators or other industry applications.

Rod Mill:It is called a rod mill, mainly because the grinding medium is a steel rod with a length of 50-100mm, and the length-diameter ratio of the cylinder is general, which can be used as a primary grinding equipment or tail crushing equipment in the concentrator.

Baseball Mill:As the name suggests, it is a device that uses steel balls and steel rods for grinding, but the difference is that this kind of ball mill is a multi-chamber ball mill (2-4 chambers). Steel rods are used as grinding medium in the initial warehouse, and steel balls or steel sections are used as grinding medium in the subsequent silos, and the length and diameter ratio of the cylinder is about 5m.

Tail Discharge Ball Mill:This kind of ball mill is a ball mill that is fed at one end of the ball mill and discharged at the other end. According to its different methods, the discharge section is divided into lattice discharge, overflow discharge, peripheral discharge and wind discharge.

Neutral Ball Mill:The two sections of the ball mill are used as the feeding place, and the middle part is the discharge section, which is equivalent to two ball mills being used in parallel, with compact equipment and simplified process.

Center Drive Ball Mill:The motor of the ball mill drives the grinding body to run by driving the hollow shaft through the reducer.

Edge Drive Ball Mill:The ball mill motor drives the large gear fixed on the cylinder at the discharge end through the reducer, and then drives the ball mill cylinder to rotate to realize the grinding operation.

That's the ball mill.

Several classification cases.

Ball Mill:There are many common classifications, if divided into by mill length:

1) Short mill When the length-diameter ratio is less than 2, it is a short mill, or ball mill. The general single chamber is used for coarse grinding or primary grinding, and 2-3 ball mills can also be used in series.

2) Medium and long grinding mill When the length-diameter ratio is about 3, it is a medium and long grinding machine.

3) Long mill When the length-diameter ratio is more than 4, it is a long mill or tube mill. Medium and long mills, which are generally divided into 2-4 silos, are used more in cement plants.

Classification according to the shape of the grinding medium loaded in the mill:

1) Ball Mill The grinding medium loaded into the mill is mainly steel balls or steel sections. This type of mill is the most commonly used.

2) The rod mill is loaded with steel rods with a diameter of 50-100mm as the grinding medium. The ratio of length to diameter of a rod mill is generally as follows:

3) Baseball Mill This type of mill usually has 2---4 bins, the first bin is loaded with cylindrical steel rods as the grinding medium, and the subsequent bins are loaded with steel balls or steel sections.

The ratio of the length to diameter of the baseball mill should be about 5, the ratio of the length of the rod bin to the effective diameter of the mill should be between, and the length of the rod should be about 100mm shorter than the rod bin, so as to facilitate the parallel arrangement of steel rods and prevent crossover and messy rods.

4) Gravel.

The grinding medium loaded into the grinding is gravel, pebbles, porcelain balls, etc. Use granite and porcelain as liners. It is used in the production of white or colored cement and ceramics.

Sanyuan Heavy Industry, Mr. Yuan will serve you wholeheartedly. See me...

Ball mills are divided into lattice type ball mills, overflow type ball mills, and dry ball mills. Iron ball mill, aluminum ash ball mill, cement ball mill, steel slag ball mill, etc.

There are two types of dry ball mills and wet ball mills

The ball mill used in power plants is divided into medium speed and low speed, medium speed grinding uses large balls, and low speed grinding uses small balls of about 8 cm.

Answer: The more commonly used specifications and models are 900 1800, 1200 4500, 1830 7000, 2200 6500, 3600 6000, 4500 6400, 5500 8500

Question: In the case of no balls, how much does the ball mill weigh in meters?

The ball mill is composed of feeding department, discharging department, rotary department, transmission part (reducer, small transmission gear, motor, electronic control) and other main parts. The hollow shaft is made of steel castings, the lining can be replaced, the slewing gear is processed by casting gear hobbing, and the cylinder is inlaid with a wear-resistant lining plate, which has good wear resistance. This machine runs smoothly and works reliably.

The main engine of the ball mill includes a cylinder, which is inlaid with a lining made of wear-resistant materials, a bearing that carries the cylinder and maintains its rotation, and a driving part, such as an electric motor, and a transmission gear, a pulley, a V-belt, etc.

Regarding the parts called blades, they are generally not the main components, and there is an inner spiral in the inlet of the component at the feeding end that can be called its inner spiral blade, and an inner spiral in the component outlet at the discharging end can also be called its inner spiral blade. In addition, if a screw conveyor is used in the auxiliary equipment at the discharge end, there will be parts called spiral blades in the equipment, but strictly speaking, it is no longer counted as a part of the ball mill.

According to the material and discharge method, dry ball mill and wet lattice ball mill can be selected. The energy-saving ball mill adopts self-aligning double-row radial spherical roller bearings, which has low running resistance and remarkable energy-saving effect. In the cylinder part, a section of conical cylinder is added at the discharge end of the original cylinder, which not only increases the effective volume of the mill, but also makes the distribution of medium in the cylinder more reasonable.

This product is widely used in non-ferrous metals, ferrous metals, non-metallic mineral processing sites and chemical and building materials industries for material grinding.

Cement ball mill.

The cement ball mill is a horizontal cylindrical rotating device with an outer gear drive. The rotation of the cylinder generates a centrifugal force that brings the steel ball to a certain height and falls.

Cement ball mill is used to grind cement raw materials, and it is divided into two types: dry and wet.

Tubular ball mills.

After the material is crushed, it is a key equipment for crushing.

Ultra-fine lamination mill.

The ultra-fine laminated ball mill is the most famous high-efficiency and energy-saving mill at present, and it is also the first mill in China.

1 ultra-fine laminated ball mill = crushing and screening system + 1 2 grinding and grading system.

The ultra-fine laminated self-grinding mill truly realizes "more crushing and less grinding", after the use of ultra-fine laminated self-grinding mill, the comprehensive benefits are significant: omitting the medium and fine crushing and screening plant and equipment, omitting the dust removal unit, taking a concentrator greater than 1500 tons per day as an example, it can save investment of more than 200-10 million yuan, and save 20-30% of energy, which is a veritable dust-free crushing and grinding energy-saving and environmentally friendly beneficiation process.

Cone ball mill.

Cone ball mill is a common ball mill in mineral processing production, the machine has changed the original mill structure, so that the body, the base frame is integrated, and can be placed on the foundation plane at one time when installed, the main bearing adopts double row self-aligning roller bearings, which can reduce the energy by 30%, improve the fine particle size, and increase the processing energy by 15 20%. Cone ball mill is the key equipment for crushing the material after it is crushed. Ball mills are widely used in cement, silicate products, new building materials, refractory materials, fertilizers, ferrous and non-ferrous metal beneficiation and glass ceramics and other production industries, for dry or wet grinding of various ores and other grinding materials.

The ball mill is the key equipment for crushing the material after it is crushed. Ball mill is one of the widely used high fine grinding machinery in industrial production, and there are many types of it, such as tubular ball mill, rod ball mill, cement ball mill, ultra-fine laminated mill, hand ball mill, horizontal ball mill, ball mill bearing, energy-saving ball mill, overflow ball mill, ceramic ball mill, lattice ball mill Ball mill is suitable for grinding all kinds of ores and other materials, and is widely used in mineral processing, building materials and chemical industries, which can be divided into dry and wet grinding methods. According to the different discharge methods, it can be divided into two types: lattice type and overflow type.
