The magnetic separating processing is a combination separating method of dryand wet magnetic separating for ore-dressing ofiron, mainly used for the third levelmagnetic separating process of mineral powder river sand making crusher. The magnetic separating processis one of the most widely used and most mature technology, which is mainly usedfor the sorting of magnetic minerals. In the magnetic separating process, magneticseparator plays a much important role. The magnetic separating process hasobvious advantages of less water, low cost, low pollution, high efficiency andhigh yield. Therefore, the magnetic separating process is a creative techniquewith high production efficiency, good product quality and no environmentalpollution. Magnetic Separating Process: First of all, the mining ores will becrushed by the jaw crusher blue metal quarry crusher.When they get a reasonable degree, they will be sent to the ball mill throughelevator and feeder, and be smashed and grinded by the ball mill. After beinggrinded by ball mill, those materials will come into the nextprocess-classification. According to the theory that the solid particle withdifferent specific gravity has different sedimentation rate in the liquid, theore mixture shall be washed and classified by the spiral classifier complete stone crushing plant. After beingwashed and classified, due to the different magnetic susceptibility of differentore, when the ore mixture passes the magnetic separator, the magnetic substancein the ore mixture will be separated by the magnetic force and mechanicalforce. This magnetic separating process is designed based on the standardprocedure process. Hongxing Company also can design the process according to theannual output and demand of customers.

According to the magnetic intensity and the material property, the magnetic separator can be designed to be downstream type, countercurrent type and semi-countercurrent type. 1. Downstream type: the feeding direction and the disk (or magnetic minerals permanent) are move in the same direction lead ore crushing machine. This tank design has increases the processing capacity of the magnetic separator. It is commonly used for the coarse select, fine select process of the strongly magnetic material and the recycle of the medium. When the feeding amount is large, the magnetic mineral particles will easily lose in the tailing. During the operation process, we should strengthen the operation management to control the level of the ore pulp. 2. Countercurrent type: the feeding direction and the disk (or magnetic minerals permanent) are move in the different direction lead ore processing plant. It is used in the coarse select process of the fine-grained ferromagnetic minerals and the scavenging operations. The sorting time is long and the recycle efficiency is high, but the concentrate grade of the ore is low. It is not suitable for the dispose process of the coarse mineral. 3. Semi-countercurrent type: the feeding direction and the disk (or magnetic minerals permanent) are move in the same direction. The pulp ore enters into the tank bottom via the feeding tube.

Ball mill is the specialized equipment for crushing materials, it plays an extreme important role in the crushing process and it is one of the indispensible super-fine grinding mills. Rotating part is considered as the most important among the feeding part, discharging part and the rotating part, which is composed of the quill shaft, barrel, lining as well as the rotating gears automatic stone crusher plant. What should be noticed here is the function of the cylinders liner, it plays a vital role in protecting the barrels rotation and reducing parts abrasion. The material of the cylindrical ball mills barrel is steel plate, the material of the lining is ceram. And the materials property determines the proportion size of the grinding ball mill. According to different discharging modes, ball mill can be classified into grate ball mill, overflow ball mill and wind discharging ball mill. Since it is the fine grinding equipment after the smashing procedure chalk powder making machine, the ball mill is mainly applied in the field of processing mine and grindable materials. Due to this characteristic, the ball mill is widely used in numerous industries like cement making, silicate making and building materials etc. When the ball mill is in operation, the contact ratio is small when devices mesh with each other, but the impact is huge. If any point of the gear bears excessive stress, the gear tooth is prone to break. The way to handle this is to revise and process accurately each gears parameters in the accelerator. During the application, because of the quenching aggrandizement layer, the ball mill will be presented with the phenomenon that it can hardly support the block contact load thus being crushed and deformed gypsum powder production line. The effective way to deal with it is to reasonably optimize and design the heat treatment, ascertain the bending degree of the tooth root then through quenching strengthening to ensure a lasting support for the contact load of the machine to decrease the times of introducing the additional load as few as possible. This series of measurements aim to guarantee a stable and high-efficiency rotation of the ball mill during its operation. At the same time, it reflects the fact that a rational structure design is significant for a normal operation of a device.

The mining machinery industry supplies all kinds of machines as tools to help industries and customers exploit and handle minerals and materials. These machines include mining machines and beneficiation equipment such as crusher, grinder, screener and separator etc. Though the mining machinery industry has played a key role in the national economy, there are also problems occurring for a long time stone crusher plant layout. So what are these problems in front of us? First, most mining machinery enterprises do not have strong enough capacity to compare with the foreign ones. They are poor at doing research and development on the mining technology, product innovation, service upgrading and business administration. Many of them dare not spend too much time, labor and capital in developing the mining industry. A lot of core devices are urgently needed in the domestic market stone crusher price list, but the Chinese enterprises cant create and manufacture them. Even when we make some necessary machines, the quality and performance wont satisfy customers. Second, we have too many problems with the variety, technology, quality and service of the whole industry, which leads the mining machinery manufacturing industry to make little use of the mines all over the country. Though there are countless mining machines on sale in the market, few of them are made by the domestic companies and most advanced ones are exported from the foreign countries. Compared with the world class equipment, the domestic one still has a long way to go. Its said that the Chinese mining industry needs 15-20 years to catch up with the international development level.

Today the market competition is getting fierce and to build up its own brand of products and service has become the core concentration for most enterprises in almost every industry. In China, there is a large market for the grinding equipment. Aiming to be the leader in the mining machinery industry, our company has made much effort to establish our own brand of grinding mills mini cement plant project. After years development, our products have been welcome in the domestic grinding equipment market and won much praise from customers. The mining machinery industry is regarded as the pillar of the national economy and plays an important role for the Chinese economic construction and social development. In the industries of mine, energy, transportation and the raw material output, the grinding equipment such as the ball mill is used to exploit mines and process raw materials. The countless supply of the all kinds of industrial products and energy will guarantee the health and rapid growth of the national economy. Therefore, we can say that the mining machinery manufacturing industry has become the foundation of the national independent industrial system and it also shows the national industrial capacity. Its meaningful for the Chinese mining machinery enterprises to make deep research and development on the domestic and foreign developing status and figure out the reasonable direction in which the future mining industry may go. Especially for the grinding and crushing equipment and technology, we need to pay the most attention to this area. At the same time, it will provide the Chinese mining machinery manufacturers with many opportunities to be extraordinary in the world.

The hammer crusherhashigh productivity, small energy consumption, safety use, easy maintenanceand wide range of applications. When design hammer crusher we need to payparticular attention to the design of wearing parts, including hammer, bearings,grate bar, impact plate; this paper mainly describes the design of grate andimpact plate. Grate is a set of steel bars of equal size to control thegranularity of broken materials open pit mining machine; When coarsely crush brittle materials, the gapof grate bars should be higher than 1.5 to 2 times of the maximum particle size;when fine crush brittle materials, it should be 3 to 6 times of particle size;grate gap should be along the movement direction of materials, that is, the gapshould be gradually extended from insider gradually along the direction ofhammerhead line speed so that the qualified products are successfully excludedwithout blocking. The spread pattern of grate bars should be vertical with themovement direction of hammer head. In addition, the gap between the two gratesis usually 60mm. The role of impact plate is to re-bounce broken materials tocrushing plate for re-crushing; in order to obtain better crushing effect, thematerials should be vertically collided to the surface of counter plate. Thesurface of counter plate includes mansard type and involute type. Mansard typeplate has simple structure, but cannot guarantee that the most effectiveimpacting; involute impact plate materials impact materials vertically withbetter effect. However, due to the involute impact board is difficult tomanufacture, we usually adopt polyline impact plate. In short, we need tobase on safety use and convenient maintenance so that design crusher with lowercost and superior performance.

Most users know well about the working principle and correct operation steps of the hammer crusher, but many of us may not know much about how to improve the hammer crushers working efficiency in short time 3ft simons cone crusher. Here our experts will show you the useful tips on the measures. First, we can change the manhole door to the leaflet door. By doing this we can make sure that the hammer crusher wont leave the small particle materials so easily during the operation of t he machine. If we find the crusher works slowly, we may check the door of the machine and open the leaflet door in order to shorten the startup time. Second, we should operate the ventilation door correctly. There are two ventilation doors installed on the two sides of the hammer crusher. Most new users dont know the functions of them so they usually leave the doors closed which will cause the rotor to stop working once the materials are loaded excessively mobile crushing plant malaysia. Facing this situation, we can open the shell for further cleaning or dredge it through the space between the grid sections. After years working practice, experts find that the best way to prevent the rotor from being stuck to a large extent by opening the ventilation door. Third, its necessary for us to adjust the space between the hammer and the grid section. The longer time we use the hammer crusher, the more abrasion will appear between the hammer and the grid section. Then the materials in the crusher will be impacted and ground under low pressure so the material particle will become too large in size. The working efficiency of the hammer will be decreased, so will its service life. So its important to tighten the grid sections in order to create the most proper distance.
