Large ore mill

1. Ball mill is the key equipment to crush the material after it is crushed. This type of mill is filled with a certain number of steel balls as grinding medium in its cylinder. It is widely used in cement, silicate procts, new building materials, refractories, chemical fertilizer, black and non-ferrous metal mineral processing, glass ceramics and other proction instries, dry or wet grinding of various ores and other grindable materials. Ball mill is suitable for grinding all kinds of ores and other materials. It is widely used in mineral processing, building materials and chemical instry. It can be divided into dry grinding and wet grinding. According to the different ways of ore discharge, it can be divided into grid type and overflow type
rod mill is a kind of mill in which the grinding body is steel rod. Rod mill generally adopts wet overflow type, which can be used as first-class open circuit grinding. It is widely used in first-class grinding of artificial sand, concentrator, chemical plant and power department. The mill is mainly composed of motor, main recer, transmission part, cylinder part, main bearing, slow transmission part, feeding part, discharging part, ring seal, playful voice station, big and small gear spray lubrication, foundation part, etc. The main recer has parallel shaft and hard tooth surface. The rod mill is an asynchronous motor connected with the pinion through the recer, which directly drives the peripheral big gears to decelerate and rotate, and drives the rotary part to rotate. There is a suitable grinding medium steel rod in the cylinder. Under the action of centrifugal force and friction, the grinding medium continuously enters the cylinder from the feeding part and is crushed by the moving grinding medium, And through the overflow and continuous feeding force, the proct is discharged out of the machine for the next process. Its working principle, structure, type, grinding medium, application, installation and installation precautions are introced in detail.

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.

3. Large ball mill is the key equipment for crushing after the material is crushed. Large ball mill is widely used in cement, silicate procts, new building materials, refractories, chemical fertilizer, black and non-ferrous metal mineral processing, glass ceramics and other proction instries, dry or wet grinding of various ores and other grindable materials
working principle of large ball mill:
this machine is a horizontal cylindrical rotating device, with outer gear drive, two bins, lattice type large ball mill. The material enters the first bin of the mill evenly through the feeding device through the feeding hollow shaft screw. In the bin, there are stepped lining plates or corrugated lining plates, which are filled with steel balls of different specifications. The rotation of the cylinder generates centrifugal force to bring the steel balls to a certain height and then fall down, resulting in heavy impact and grinding on the material. After rough grinding in the first bin, the material enters the second bin through a single-layer partition board. The bin is inlaid with a flat lining board and steel balls to further grind the material. The powder is discharged through the discharging grate plate to complete the grinding operation
structural features of large ball mill:
the machine is composed of feeding part, discharging part, rotary part, transmission part (recer, small transmission gear, motor, electric control) and other main parts. The hollow shaft is made of cast steel with detachable inner lining. The rotary gear is processed by casting gear hobbing. The cylinder is inlaid with wear-resistant lining plate, which has good wear resistance. The machine runs smoothly and reliably
note: dry ball mill and wet lattice ball mill can be selected according to material and ore discharge mode.

5. Not the largest, many manufacturers can customize according to your data. What's more, the ball mill is too big, and it doesn't make much sense. Lifting and installation is also a problem. If the proction demand is large, a few more large ones will do.

6. There are many types of large-scale ball mill price, and the price is not the same. Generally speaking, large-scale ball mill is the key equipment for crushing after the material is crushed. Ball mill is widely used in cement, silicate procts, new building materials, refractories, fertilizer, black and non-ferrous metal mineral processing, glass ceramics and other proction instries, dry or wet grinding of various ores and other grindable materials. There are many types of large-scale ball mill equipment, such as large-scale cement ball mill, large-scale fly ash ball mill, large-scale grinding stone ash ball mill and so on.
