Grid ball mill is widely used in smashing all kinds of ores and other materials, ore dressing and national economic departments like building and chemical industries etc. The size of ore shall not exceed 65mm and the best feed size is under 6mm. The effect in this job is better than coarse grinding. Grid ball mill consists of the shell, feeding part, discharging part, main bearing, lubricating system, driving system and other parts. There is wearing a liner inside the shell, and both ends of the shell are provided with a flange. The end cover of the mill is connected with the flange plate. The feeding part consists of the head, trunnion and feeding device. The discharge part includes the grid plate, head, and discharge trunnion.
Wet Grid ball mill is mainly used for mixing and grinding materials in two types: dry grinding and wet grinding .It has advantages of fineness uniformity and power saving. The machine uses different types of liner to meet different customer needs. The grinding fineness of material can be controlled by grinding time. The electro-hydraulic machine is auto-coupled and decompressed to reduce the starting current, and its structure is divided into integral type and independent type.
Compared with similar products,Wet Grid ball mill has the characteristics of low investment, low energy consumption, novel structure, simple operation, stable and reliable performance. It is suitable for mixing and grinding ordinary and special materials. The users can choose the right type, liner and medium type by considering the specific gravity, hardness, yield and other factors. The grinding medium is Wet Grid ball.
1.The ball mill is composed of a horizontal cylinder, a hollow shaft for feeding and discharging, and a grinding head. The main body is a long cylinder made of steel. The cylinder is provided with an abrasive body, and the steel lining plate is fixed to the cylinder body. The grinding body is generally a steel ball and is loaded into the cylinder according to different diameters and a certain proportion, and the grinding body can also be used with a steel section.
2.According to the particle size of the grinding material, the material is loaded into the cylinder by the hollow shaft of the wet grid ball mill feeding end. When the ball mill cylinder rotates, the grinding body acts on the cylinder liner due to the action of inertia and centrifugal force and friction. It is carried away by the cylinder. When it is brought to a certain height, it is thrown off due to its own gravity. The falling abrasive body crushes the material in the cylinder like a projectile.
3.The material is uniformly fed into the first chamber of the mill by the feeding device through the hollow shaft of the feeding material. The chamber has a step liner or a corrugated liner, and various steel balls are loaded therein. The rotation of the cylinder generates centrifugal force to bring the steel ball to a certain extent. The height drops and then hits and grinds the material. After the material reaches the rough grinding in the first bin, it enters the second bin through the single-layer partition plate. The bin is embedded with a flat liner with steel balls inside to further grind the material. The powder is discharged through the discharge raft to complete the grinding operation.
The main function of the steel ball in the ball mill is to impact crush the material and also play a certain grinding effect. Therefore, the purpose of grading steel balls is to meet the requirements of these two aspects. The quality of the crushing effect directly affects the grinding efficiency, and ultimately affects the output of the ball mill. Whether the crushing requirement can be achieved depends on whether the grading of the steel ball is reasonable, mainly including the size of the steel ball, the number of ball diameters, and the ball of various specifications. Proportion and so on.
The ball mill is composed of the main part such as a feeding part, a discharging part, a turning part, a transmission part (a reduction gear, a small transmission gear, a motor, and electric control). The hollow shaft is made of cast steel, the inner lining can be replaced, the rotary large gear is processed by casting hobbing, and the barrel is embedded with wear-resistant lining, which has good wear resistance. The machine runs smoothly and works reliably.
Heavy StirredBall Millmainly consists of jar with inner grinding media, stirring device and other auxiliary devices such as recycling device, cooling device, timing device, speed adjusting controller, and etc. Its advantages of high efficiency and fine granularity meet technological requirements of various processes. Stirred ball mill is a kind of ideal equipment that are used to crush new materials and research painting for universities, research centers and enterprises because of its features of small batch, low power and low price.
When machine rotates at high speed under driving of main axis and grind media move irregularly at the same time, the grind material can be crushed, ground and sheared into fine granularity powder. The size, shape and matching ratio of the grind media can affect the grinding result. Generally speaking, the bigger the mill media is, the finer the grinding powder is. A proper match ratio of grind medias and proper adjustment of rotation speed can get better grinding effect.

AG mill (autogenous mill) is a medium-free mineral grinding equipment. The raw ore and the coarsely crushed ore are directly fed into the AG mill. No other medium is involved in grinding. Only the impact between the ore is used for self-grinding. The ore larger than 100mm in the AG mill plays the role of grinding medium. When the AG mill operation is started, the ore is directly self grinding.
What is a SAG mill?The structure of the SAG mill (semi-automatic grinding mill) and the AG mill (autogenous grinding mill)are exactly the same, except that a certain proportion of auxiliary grinding media such as steel balls or steel rods are added as needed. During the process of the AG mill operation, some ores with diameters greater than 20mm but less than 80mm are not easily ground. In this case, the SAG mill design can do that. In general, the SAG mill manufacturers will control the addition amount of medium such as steel ball at 2-8%, so that the capacity of semi SAG mill to process materials can be increased by 10-30%. The SAG mill liners wear will increase by 15% due to the impact of medium such as steel ball during the SAG mill operation.
How does a SAG mill or AG mill work? The working principle of the SAG mill and AG mill is basically the same as theball mill machine, but the barrel diameter of the SAG mill and AG mill is larger. The raw ore enters the AG mill through the feedinginlet, and the material is brought to a high place under the rotation of the barrel and then falls. During this process, materials collide and rub against each other. The thrown material falls on the AG mill liners, and is rebounded to the other side of the barrel wall due to impact, and then collides with the falling material again. The impact from different directions makes the materials of different sizes evenly distributed in the barrel. Due to the action of inertia, centrifugal force and frictional force, the material makes reciprocating grinding movement in the AG mill. In the SAG mill, the materials themselves collide with each other and at the same time, they also collide with the grinding media such as steel balls for grinding.
During the dry type SAG mill operation, the materials that have been ground to meet the requirements are discharged from the SAG mill with the airflow of the fan, and then enter the corresponding classification equipment for classification. In the process of discharging, the coarse-grained materials return to the SAG mill with the help of self weight for regrinding.
In the design of wet type SAG mill, the materials that meet the grinding requirements will be sent out of the barrel by the force of water, and the unqualified large-particle materials are left in the SAG mill due to gravity.
Conventional grinding mill machine(ball mill, rod mill, etc.) and SAG mill (AG mill) have different requirements for the properties of the materials to be ground. Therefore, when selecting the grinding mill machine in the mineral processing process, it is necessary to select the appropriate equipment after material test and analysis and careful comparison. The following are several principles that should be followed when selecting mining equipment.
