2. The ball mill often used in mines can be divided into short simple type, cone type and long cylinder type according to its structure. The cylinder length of the short cylinder ball mill is less than the diameter of the cylinder, the conical ball mill is composed of the cylinder part and the conical parts on both sides, and the cylinder length of the long cylinder ball mill is greater than the diameter of the cylinder. According to the medium used, it can be divided into ball mill and rod mill. At present, no medium grinding machine is used in mines. According to different ways of ore discharge, it can be divided into forced discharge lattice ball mill and gravity discharge overflow ball mill. According to the transmission system is divided into three categories: 1. By the V-belt drive as a deceleration of the transmission system. The advantages of this kind of transmission system are that the transmission parts are easy to manufacture, the price is cheap and the maintenance is simple. But the disadvantages are large area and low transmission efficiency. 2. The gear recer is used as the transmission system. The advantages of this transmission system are reliable transmission and compact structure. But the disadvantage is that the recer is more expensive, causing trouble. 3. Low speed motor is used as the transmission system of deceleration. The advantages of this kind of drive system are that the whole drive system is very compact, the transmission efficiency is high, the metal consumption is small, the motor is synchronous motor, so it can also improve the power factor of the power network. But electric motors are expensive. Mine ball mill is generally composed of feeding, cylinder, discharge, transmission, main bearing, recer and other main parts, as well as coupling, lubrication system, electrical equipment and other auxiliary parts. The specification of ball mill is expressed by the inner diameter and effective length of the cylinder.

See if your mill has reached the designed fineness, if not, it is easier; It is difficult to improve the fineness of the original design. Generally, we can start from the following aspects:

1. to see whether the steel ball filling rate is appropriate, generally more than 35%. Generally, increasing the filling rate can improve the grinding fineness

2. to see whether the steel ball ratio is reasonable, it requires professional knowledge. Generally, increasing the proportion of small balls can improve the grinding fineness

3. to see if the grinding concentration is appropriate, it is generally more than 75%, or even higher. Generally, increasing grinding concentration can improve grinding fineness

4. to see the grading efficiency, we also need to have professional knowledge

5. to see if the ore feed is appropriate. Generally, the grinding time can be increased and the grinding fineness can be improved when the ore feeding amount is small

5. In the preparation of aerated concrete raw materials, the most important equipment is the ball mill, and the mining ball mill is a professional mining equipment, which is used for grinding lime, gypsum, sand, slag and other materials. Only after grinding and reaching the required fineness can the materials be fully mixed and mutually used to make the procts reach the strength. Grinding is an important procere in the proction of aerated concrete. The power consumption in the grinding process is large, and the ball mill is generally the equipment with the largest motor capacity in the aerated concrete factory. Ball mill is mainly used in mineral processing, ceramics, chemical instry, cement, glass, refractory and other instries. Ball mill is divided into dry and wet, dry for refractory, cement, fertilizer, glass instry; Wet type is used in mineral processing, ceramics and chemical instry. In recent years, our factory has developed and proced bearing driven high-efficiency and energy-saving cone ball mill, saving 25-30% energy

6. It depends on the size of the proction line you open. It's more than 100000 new mills. I suggest you buy old ones. Now the market is not good. I've seen many new machines, but they are dismantled. They are sold higher than scrap iron. We are flour collectors, so we often see each other.

7. Ball mill is used to crush materials. Its characteristics are mainly reflected in the large crushing ratio, simple structure, reliable working problems and so on. With the needs of proction, a variety of different types of ball mills also came into being< According to different classification criteria, the types of ball mills are as follows:

first, according to the ore discharge mode of ball mills,
according to the ore discharge mode, ball mills can be divided into two categories:
one is the central ore discharge ball mill, such as overflow type ball mill
one type is peripheral discharge ball mill, such as lattice ball mill

the structures of the two kinds of ball mills are basically the same, and the difference is that there is no discharge grid in the overflow type ball mill. Due to the different characteristics of ore discharge, the two types of ball mills also have their own uses and advantages and disadvantages

generally, overflow ball mill has fine grinding fineness, which is more suitable for regrinding of materials. Compared with overflow ball mill, its working performance and proction capacity are outstanding, but its structure is slightly complex, and its grinding proct particle size is also larger than overflow ball mill, so it is more suitable for rough grinding of materials< According to the working mode, ball mills can be divided into continuous ball mills and intermittent ball mills. As the name suggests, their different working modes determine their different working characteristics

continuous ball mill: continuous ball mill is often used in general concentrator and coal water slurry plant

intermittent ball mill: in the processing of ceramic raw materials, glaze and other chemical procts, e to the particularity of the material, the intermittent ball mill is often used for grinding. The intermittent ball mill can control the particle size of the material by adjusting the grinding time, but its grinding efficiency is not high, and the operation is not very convenient< According to the way of placing the cylinder, there are two ways of placing the cylinder: vertical ball mill and horizontal ball mill. The vertical ball mill is a new type of ball mill with the cylinder fixed. Through a lot of experiments, it is found that the vertical ball mill has the advantages of high grinding efficiency, low energy consumption and low noise. This also makes the vertical ball mill more and more users

the horizontal ball mill is a kind of mill that the cylinder is horizontally placed on the ball mill frame, and the motor drives the whole machine to rotate and move, with large crushing ratio and high grinding efficiency< Four, according to different uses, there are many uses of ball mills, which are used in many instries, such as mining, sand, coal, ceramics, cement, etc

the above are some ways to classify different forms of ball mills. In addition, there are also special ball mills such as iron ball mill, lime ball mill, small ball mill, large ball mill and planetary ball mill. If you want to know more about ball mills, you can directly consult the ball mill equipment manufacturer.

9. The operation rate of mineral processing ball mill is also called operation rate. It refers to the percentage of actual working hours of grinding classification unit in calendar hours, which is calculated once a month for each ball mill in proction, accumulated throughout the year and averaged monthly. The operation rate of ball mill reflects the management level of concentrator. It can also reveal and analyze the reasons that affect the abnormal operation of grinding classification unit, and take effective improvement measures.

10. Ball mill models include energy-saving ball mill, vertical ball mill, tubular ball mill, conical ball mill, dry ball mill, wet ball mill, lattice ball mill, overflow ball mill, ceramic ball mill, rod mill, Raymond mill, etc; The type selection of ball mill is determined according to the process and output; According to the field cases of machinery in Xing mine, there are many types of ball mills used in gold ore dressing, such as cone ball mill, wet ball mill, lattice ball mill, overflow ball mill, rod mill, Raymond mill, etc.
