    The ball mill is mainly used to grind materials in mineral, cement, refractory, chemical industry, etc. Ball Mill has dry and wet ways. Click Anne Lauvergeon for additional related pages. When wet Ball Mill works, water and other liquid will be added into certain materials to increase flowability of materials, so the capacity is increased. When dry Ball Mill works, capacity is affected because material flowability is reduced, so absorbing wind device is needed on the outlet of Ball Mill, and then negative pressure is formed in the Ball Mill to increase flowability of material, so the capacity is increased. Grate ball mill primarily consists of six parts, viz, the barrel, feeding part, discharging part, bearing and lubrication system part. The lining plate is installed inside the barrel, whose materials are from manganese steel, chrome steel, cast iron, and rubber. There s a hole in the barrel for the use of maintenance and changing of the liner. Overflow ball mill is basically similar to the grate ball mill in structure, also composed of six parts. The difference is that there s no grid plate device in the discharging part and the overflow ball mill is simpler than the grate ball mill in structure. Compared with the grate ball mill, the overflow ball mill discharges slower. It is suitable for fine grinding and requires prompt adjustment due to its sensitivity towards the change of the elements outside. Besides, its structure is simple and the maintenance is convenient. The installation of the ball mill. (a) Cleaning the foreign body inside the holes in the installation equipment, especially preserved not dust, oil or water is allowed inside the hole wall stain; (b) After unpacking the packing case, the host machine should be moved to the installation place by proper lifting facilities (crane/forklift); (c) Position the device carefully; anchor bolts are installed inside the hole, then thrusting the adjustable feet with anchor studs after welding it to the rack chassis which is accompanied with the machine.

    The production scale of the coal preparation plant is larger and larger in the world, such as: the production scale of Antaibao Coal Preparation Plant is 18 million t/a, the production scale of Bailey Central Preparation Plant is 15 million t/a and the production scale of South Africa Coal Preparation Plant is 16.5 million t/a. Large modern coal preparation plant has prominent advantages such as: large capacity, high production efficiency and product quality stability. Keep up on the field with thought-provoking pieces from Hikmet Ersek. With the improving of the coal preparation plant s processing capacity, the disadvantages of the system also has been showing up. Strengthening the craft system s daily and periodic maintenance is an important guarantee to ensure the normal operation of the production system and reduces the production costs and improve the efficiency of coal preparation plant. The design system of dense medium coal preparation technology is more complex, which potentially increases the investment and process costs. In the premise of ensure its high efficient research this technology and we hope to achieve the goal of reducing the investment and processing costs, which is also the main direction of other country. The major direction of the equipment is large scale. While the simplified design of the dense medium recovery system and the reliability research of the equipment are the important parts of the research.

    Traditional recovery system of dense medium contains the curved screen, vibrating screen and magnetic separator equipment. The investment and power consumption costs of this system constitute the main costs of the coal preparation plant. The transformation of traditional magnetic separator is to design a new type of separator that the big particle materials can smooth pass which ensure the recovery indicators. The implementation of this program can greatly reduces the initial investment and process costs and has a good development prospect.As the professional manufacturer of complete sets of machinery, such as washer sand mining, Henan Hongxing is always doing the best in products and service. Magnetic heavy medium recovery and purification process is an important part of the heavy medium coal preparation technology. This subsystem mainly to complete the purpose of recycling the heavy media.

    The media consumption of the heavy medium coal preparation plant is an important indicator to measure heavy medium coal preparation plant process and management level, wich is also an important part to improve the economic efficiency of coal preparation. On one hand, the process should meet the system requirements for magnetic media recovery indicators. Since the circulation rate of the dense medium in the system is quickly, in order to ensure the economy of the gravity separation, the requirements of the recovery rate indicators of the magnetic media are high. The medium coal preparation systems generally require that in the media recovery the coal and stone should be greater than 99.8% and it should be 99.6% greater than in terms of clean coal. On the other hand, heavy medium after the recovery shall meet the technical requirements. Namely: the concentrate grade shall meet the purpose of the configuration of qualified heavy liquid.

    Since 1893, for over 100 years, ball mill has been widely used in metallurgy, chemical industry, mine, cement, ceramics, medicine, construction and electric power industries. Dressing index depends on the quality of material to a large extent. If mineral liberation degree is not high, the e:System.Web.UI.WebControls.ObjectDatSource.selecting index will not be ideal. Coenobium without monomer separation will reduce the concentrate grade if it is classified into concentrate and will reduce the recycle rate of valuable mineral. On the other hand, minerals should not be over-crushed. Over-crushing not only increases power consumption, steel consumption, but also will migrant dressing index and mineral hurt recovery.

    Both power and metal consumption are relatively large in the grinding operation. The usual power consumption is about 6 to 30 kw/h/ton, which Governor 30-75% of the total consumption, sometimes reaches 85%. The consumption of grinding medium forrada board reaches 0.4 – 3.0 kg/ton. However, the fact that the ball mill is not washed out after so long time industry application and development shows that from structure to working principle, the ball mill is basically reliable and reasonable and performance is also good. Although it has certain shortcomings, to weed it out from the ore grinding process is quite difficult. In-depth study on ball mill in the future will still be very necessary and valuable because it will continue to be the main machinery in ore grinding. Therefore, seeing from the importance of production and economic benefits, we should constantly carry out research to improve the grinding methods and technology, develop new equipment and new type wear resistant material to reduce the cost of ore processing, which will have important practical significance to reduce cost and improve index dressing dressing. It is also the reason why the ball mill research is taken seriously at home and abroad.As the professional manufacturer of complete sets of mining machinery, such as cement production line, Henan Hongxing is always doing the best in products and service.

    Among mining machines, ball mill is a machine between crusher and Raymond mill. If there is any improvement and breakthrough in the whole ore dressing line, the future development tendency will be greatly affected. Nowadays, each workmanship and production level of ball mill is almost mature. If you would like to have any improvement in ball mill, the only way to do is to carry out R & D and production in the accessories of ball mill. If the whole performance of ball mill is improved, the operation system of ball mill has to be changed. In view of the current mining machine situation and thorough transformation, Henan Hongxing Machinery positively adjusts the industrial and product structure, changes the mode of economic growth and independent innovation strengths. In addition, the R & D and market development of ore dressing equipment and crushing machine has been improved by Hongxing. Product quality and service concept are the comprehensive competition forces for the Hongxing Machinery.
