Heavy duty, continuous type ball mill is with three compartment and screen. Replaceable Liners are fixed inside entire mill. Liners material and shape is selected based on material to be grind. Input material is fed in two primary grinding compartments. Large diameter balls for reduce particle size are laying inside first compartment. Material comes into second compartment for further grinding. Small size Balls are laying inside second compartment. Material comes into third for fine grinding. Smaller size media are laying inside third compartment for fine grinding. Diaphragms may place to regulate material level and control retention time. Material is feed and discharged through hollow trunnion at opposite end.
The split set is widely used in coal mining. It is a new type of full-length anchor, and the three-dimensional part is a high-strength steel rod with a longitudinal slit. When installed in a hole slightly smaller than the pipe diameter, it can immediately apply radial pressure on the hole wall and the friction force to prevent the slide of the surrounding rock, plus the supporting force of the bolt tray, so that the surrounding rock is in a three-way stress state, and the rock stability is realized. Advantage: 1. Good support effect. 2. Low support cost. 3. Low labor intensity. Product parameters Split set is mainly composed of anchor rod and tray. The anchor rod has two wall thicknesses, 2.5mm and 3.0mm. There are two types of trays, one with earhook and one without. Common specifications: �?30, �?35, �?39, �?43, �?46.

Overflow Type Ball Mill Overflow Type Ball Mill Overview: The main component of wet overflow ball mill is a cylinder with bigger diameter and smaller length which is revolved by transmitting machinery. Materials are put in cylinder through the feed opening and then thoroughly grinded. The falling course of iron balls and ores can produce huge falling impact and autogenous grinding. Overflow Type Ball Mill Features: 1. The jack-up device of wet grate ball mill makes maintenance easy. 2. The hydrostatic and hydrodynamic bearings ensure the smooth operation of wet grate ball mill. 3. The low speed transmission of wet grate ball mill contributes to easy overhaul and maintenance. 4. The oil-mist lubrication device guarantees reliable performance of bearings. 5. The gas clutch adopts the flexible start-up model. Working Principle : Principle of overflow ball mill: the main component is a cylinder with diameter and length at a reasonable proportion. Driven by the transmission device, the cylinder rotates with the materials fed from the cylinder inlet and crushed by the falling impacts and autogenous grinding of the steel balls and ores in the cylinder. Due to the continuously feeding materials, the pressure pushes materials to the outlet and the grinded materials are discharged from the cylinder outlet. Qualified materials flow from the cylinder outlet. In wet grinding, the materials are taken out by the water flow. There are backpitch impellers in the hollow shaft, which can make the balls and coarse ores in the overflow return to the mill. With simple structure, higher operation rate, and rolling bearing, the energy conservation is significant.
Raymond Grinding Mill Raymond Mill is suitable for grinding of all kinds of materials whose Mohâ??s hardness is below 9.3, such as calcium carbonate, barite, dolomite, calcite, limestone, kaolin, bentonite, marble, gypsum, quartz, feldspar, clay, talc, fluorite, clay, white mud, mica, refractory material, glass, total about 1000 kinds of materials. Raymond Grinding Mill Features: 1. High efficiency and precision classifier, unique airtightness, which canensure the quality of end products. 2. The wear-resistant volute can effectively improve the material liquidity, decrease the air volume loss and avoid air energy loss. 3. The bevel gear overall dive can achieve higher transmission efficiency, easy to install and adjust, long service life and lower cost. 4. Inner thin oil lubrication system can realize lubrication between main bearing and drive bearing without any additional lubrication pump, easy to maintenance. 5. The curved surface shovel with split design, only the blade to be replaced during maintenance, thus the shovel has long service life. 6. The isolated cyclone collector can effectively improving the classifying efficiency and accuracy. Working Principle : After the materials enter the grinding chamber of the main frame, the grinding roller swings outward and presses closely upon the grinding ring due to the centrifugal force generated by the rotation of the main shaft. The blade carries materials to the space between the grinding roller and grinding ring, and materials are ground as the grinding roller rolls. After being ground, the powder is selected by classifier via the cycle wind of the blower and the rough powder will be back to the grinding chamber for regrinding. The qualified powder is brought into the powder collector together with airflow. The powder comes out as end products while the airflow goes back to the powder collector in cycling to make the machine work normally. The remained airflow comes out after purification by dust filter.
The grinding efficiency of the mill is high, the collision times of grinding medium is 50 times that of ordinary ball mill, and the grinding speed is 10 ~ 30 times higher than that of ordinary ball mill.

The rod mill is decelerated and driven by the motor through the reducer and the surrounding large gear, or by the low-speed synchronous motor directly through the surrounding large gear to drive the cylinder to rotate. The cylinder body is equipped with appropriate grinding medium - steel rod. Under the action of centrifugal force and friction, the grinding medium is lifted to a certain height and falls in a throwing or discharging state. The ground material continuously enters the cylinder from the ore feeding port, is crushed by the moving grinding medium, and the product is discharged out of the machine through overflow and continuous ore feeding to carry out the next process [2]. When 80% of the product particle size is required to be less than 2.0% to 0.5mm, the rod mill is generally used. The product particle size of the rod mill is generally no more than 4.7MM and no less than 0.4mm. The ore feeding particle size of the rod mill is 80%, less than 20mm to 4mm, and the maximum ore feeding particle size can also be up to 50mm. Due to the material of the grinding rod and other reasons, the length of the grinding rod shall not exceed 6.1m, otherwise it will cause bad consequences such as disorderly rods. Therefore, the specification of the rod unloader has not exceeded specification 4.6 Ã?? 6.3m. When the ore is fed into the rod mill, the coarse particles are at the feeding end and the fine particles are at the discharge end: therefore, the rod group cannot be completely parallel and inclined during operation, which is also a reason why the grinding rod cannot be too long.
Vibration mill is a kind of ultra-fine grinding equipment with ball or rod as medium. Medium vibration in the mill can crush materials less than 2mm to several microns. It has the advantages of high efficiency, energy saving, space saving and uniform product particle size. It has important advantages in the field of ultra-fine grinding and has been widely used. The Palla tube type vibration mill developed in the 1970s in West Germany has entered more than 40 countries and regions around the world. From the ultra-fine grinding of industrial minerals and raw materials in the general metallurgy, building materials, non-metallic minerals, coal, chemical industry, light industry and other departments to the deep processing of new synthetic materials and magnetic materials, more than 100 kinds of materials have been processed. Classification According to the number of cylinders: single cylinder and multi cylinder; According to the excitation form, it can be divided into inertia type and eccentric rotation type; Grinding is divided into dry method and wet method according to whether water powder is added or not; According to the operation method, it is divided into intermittent type and continuous type.
