1.Under the premise that the classifier overflow fineness and the ball mills ore supply amount are unchanged, the amount of sand returned is reduced, which indicates that the grinding function has been strengthened and the ball filling amount is suitable.At this time, the ball amount can be appropriately increased to increase grinding efficiency.
The production capacity of the ball mill is determined by the amount of material required to be ground, and it must have a certain margin when designing and selecting.There are many factors affecting the production capacity of the ball mill, in addition to the nature of the material (grain size, hardness, density, temperature and humidity), the degree of grinding (product size), the uniformity of the feeding material, and the portion of loaded, , and the mill structure (the mill barrel length, diameter ratio, the number of bins, the shape of the partition plate and the lining plate).It is difficult to theoretically determine the productivity of the mill.The grinding mills production capacity is generally calculated based on the newly generated powder ore of less than 0.074 mm (-200 mesh).V effective volume of ball mill, m3; g2 material less than 0.074mm in product accounts for the percentage of total material, %; g1 material less than 0.074mm in ore feeding accounts for 0.074mm in the percentage of the total material, %; qm unit productivity calculated according to the new generation grade (0.074mm), t/(m3.H).The values of qm are determined by experiments or are calibrated in production with similar ore physical properties and the same equipment and working conditions.When there is no test data and production calibration value, it can be calculated by formula (1-3).Di1- standard mill diameter, m; k4 feed size and product size coefficient of mill.G3 g4 the production capacity of existing or experimental mills with newly designed and parameters (feed size or product size calculated according to the new generation 0.074mm level) is shown in table 1-6.The values of g1 and g2 above should be calculated according to actual data.If there is no actual data, they can be selected according to tables 1-7 and 1-8.
It could carry out dry and wet millings on different materials.Limestone ball mill is a mineral processing machine for milling the materials into powders after they are crushed.It is widely applied to the production of cements, silicate products, building materials, fireproof materials, fertilizers, glass, ceramics as well as nonferrous and ferrous metal processing industries.
The first step of ore dressing is to use crusher to break the material, and then use the ball mill to further crusher it in order to achieve the desired result.As our country released the guidance and policy on energy conservation and emissions reduction, in rock grinding and identifying equipment aspect, we have to pay special attention to the introduction and co operational development of energy-saving and super fine equipment., increase the introduction of foreign advanced technology and equipment, try to research and develop our own innovative products, increase the development and manufacturing of energy-saving dressing machinery of the superfine iron ore, including strong magnetic equipment, highly efficient and energy-saving ball mill, the high-tech planets ball mill, subtle particle flotation machine and flotation column, etc.In addition, we should make much further research on the multiple tank magnetic separator with multi-stage and consecutive dressing performance characteristics.

The big gear of the ball mill fits on the mill shell, the size is bigger, the big gear is divided into half structure, the radial and axial run-out of the big gear are controlled within the national standard, the aging treatment is up to the standard, and the stress and deformation after processing are prevented.The big gear seal adopts the radial seal and the reinforced big gear shield.It is welded and manufactured in the workshop.The geometric size is controlled, the deformation is prevented and the sealing effect is ensured.The small gear transmission device adopts the cast iron base, the bearing base and the bearing cap are processed at the same time to reduce the vibration in operation.Large and small gear lubrication: the use of spray lubrication device timing quantitative forced spray lubrication, automatic control, no manual operation.The gear cover is welded by profile steel and high-quality steel plate.In order to enhance the stiffness of the gear cover, the finite element analysis is carried out, and the supporting structure is added in the weak part according to the analysis results.
Three.Powder screening grinding technologyat present, the domestic part of the high-yield, high fine, screening and grinding screening device in the sieve plate aperture (2.5 ~ 3.5mm), through a small feeding area (the only area) of about 30% of the material through the sieve easily loose materialscoarse, grate grate sew easy to plug the weaknesses.Resulting in increase in production in the course of small fluctuations in the quality, and sometimes even to stop the machine, processing sieve and clean up the grate grate seam, causing great losses to the user.Center after domestic dozens of high-yield, high-fine grinding, sieving analysis and demonstration of innovative development within the powder screening mill technology, bringing together the kang will board mill, high-yield, high fine sieve mill technology in response to these shortcomings has made significant improvements.The technology and milling equipment using the new screening device in a ball mill, the basis of the original mill production process, taking into account all aspects of the process of production systems, such as clinker particle size, temperature, grindability, the mixed material types of water.Within the selected sub-device, mill grinding process in a timely and effective thickness of the particle separation.
Beneficiation production line is mainly consist of jaw crusher, ball mill, classifier, magnetic separator, the flotation machine, the thickener machines and dryer, when it is equipped with vibrating feeder, hoist, v belts ,it can form a complete beneficiation production line which is with characters of high-efficiency, low-power consumption, high productivity, and reasonable disposition, etc.
The cement ball mill is mainly used for grinding the finished products and raw materials of cement plants, and is also suitable for grinding various ore and other grindable materials in industrial and mining enterprises such as metallurgy, chemical industry, and electric power.Cement grinding is the last process of cement production, it is to mix cement clinker and a small amount of gypsum, and then grind the mixture to a certain fineness, that is cement.You may also interest in the ball mill product price, lime ball mill, quartz ball mill.cement grinder types cement ball mills can be divided according to discharge method: grate ball mills and overflow mills, and can be divided into wet mills and dry mills according to their processing conditions.
As with other types of mills, a rod mill is used to grind material into fine powder, but differs from a ball mill in that it employs long steel rods instead of balls .
When to choose the ball mill and when to choose the grinding mill? in the following text, we analyze the structure principle, working mode, applied materials, production capacity, cost and other aspects to show a clear comparation between these two milling machine stars.
