The ball mill is one of the most widely used super fine grinding machine in the industry and it is the key grinding equipment after materials have been crushed.Details+
Impact crusher is generally used as a secondary crushing equipment. It can process materials with a side length of less than 1300 mm. Its compressive strength can be as high as 350 MPa. It has the advantages of large crushing ratio and cubic particles after crushing. The impact crusher has a shaping function. It is suitable for crushing medium-hard materials, such as limestone crushing in cement plants, with the advantages of large production capacity and small discharge particle size.Details+
In coal-fired power plants coal mills are used to pulverize and dry to coal before it is blown into the power plant furnace.Details+
The compound crusher is used to crush a variety of medium hard ores, such as limestone, clinker,coal and other ores, which can be widely used in mining, metallurgy, refractory, cement, coal,glass, ceramics, electric power and other industries, and is one of the commonly used equipment in the crushing production line and the sand making production line. This series of crusher is a new product based on our company's PEL vertical compound crusher and optimized with domestic and foreign fine crushing technology. Its performance has reached the domestic advanced level. It is mainly for all kinds of ore with compressive strength not exceeding 200MPa and water content less than 15%.Details+

The HSA-1 High Speed Attritor is generally used in a continuous mode. The material is charged into these lab mills at the top and is discharged out the bottom side, making use of centrifugal force. The HSA is used when smaller particle size (generally 40 mesh) materials are fed into the machine and micron size end product is desired. Also, it is often used for fibrous and polymer …More Details

The particle size reduction equipment that completes those tasks is varied. Typical examples include: Ball mills, in which a container is filled with grinding media and is rotated on its own axis. Planetary ball mills, in which a ball mill is attached to a disc that rotates in the opposite direction of the container. This unique construction takes advantage of centrifugal force and the Coriolis …More Details

Jun 01, 2018 · Dry batch milling tests were performed in a laboratory scale ball mill measuring 30.2 by 28.2 cm. The mill specifications are given in Table 1. A constant ball load of 20% was maintained in all the tests with a ratio of 0.5 for binary and 0.33 for trinary ball mix. Table 1More Details
The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclonesMore Details

Ball mills normally operate with an approximate ball charge of 30%. Ball mills are characterized by their smaller (comparatively) diameter and longer length, and often have a length 1.5 to 2.5 times the diameter. The feed is at one end of the cylinder and the discharge is at the other. Small versions of ball mills can be found in laboratories where they are used for grinding sample …More Details

Fig. 8 represents the comparison of selection functions obtained experimentally in the laboratory ball mill and values obtained from the equations of model E3 (see Eqs. (8) and (9)). Selection functions were plotted against the lower limit of the size intervals. The advantage of model E3 is once more confirmedMore Details
Laboratory mills work with different particle size reduction principles. Which type of mill is used for a particular particle size reduction task always depends on the breaking properties of the sample material. Size reduction machines for large particle sizes above 40 mm are known as crushers or shredders while particle sizes below this areMore Details
Abstract. Planetary ball mills are well known and used for particle size reduction on laboratory and pilot scales for decades while during the last few years the application of planetary ball mills has extended to mechanochemical approaches. Processes inside planetary ball mills are complex and strongly depend on the processed material and synthesis and, thus, the optimum …More Details
