Molybdenum ore ball mill ApplicationBall mill, a type of Grinding Mill, is a cylinder-shaped device used to grind materials like ores, chemicals, ceramic raw materials and paints. The ball mills are the key milling equipment after material has been crushed. It is divided into two rubbing way, the dry and the wet Ball mills mainly composed of charging and discharging, cyclone and rotation parts (like redactor, minor rotation gear, motor, electric machine, etc.)Molybdenum ore ball mill PrincipleThe ball mill is a horizontal rotating device transmitted by the outer gear. The materials are transferred to the grinding chamber through the quill shaft uniformly. There are ladder liner and ripple liner and different specifications of steel balls in the chamber. The centrifugal force caused by rotation of barrel brings the steel balls to a certain height and impact and grind the materials. The ground materials are discharged through the discharging board thus the grinding process is finished.Specifications of Molybdenum ore ball mill Modelcylinder speed(r/min)Ball Weight(t)feed particle size(mm)Give Makings Size(mm)Output(t/h)motor power(kw)Total weight(T)900×180036~381.5≤200.075-0.890.65-218.54.6900×3000362.7≤200.075-0.891.1-3.5225.61200×2400363≤250.075-0.61.Flotation Machine5-4.830121200×3000363.5≤250.074-0.41.6-53712.81200×450032.45≤250.074-0.Flotation…

Materials appropriate,Vibratory feeder reasonable distribution of residual stress may be progress processing, the progress of stress erosion ability and prolong the service life of material components factors. And not appropriate residual stress will reduce processing, the stress of erosion, lose size accuracy, and even cause deformation and cracking and other early failure accident, so mechanical parts large mechanical components residual stress to the processing,Mineral impact crusher fight stress erosion ability, size not disorderly service life is very important influence. Materials heat treatment effect the quality of ball mill, function is the most important factor in service life. Heat treatment can change the ball mill stress distribution, make the material surface to form a very wide pressure stress distribution belt,Cone crusher thus it can greatly improve the actual material handling bearing capacity. The ball mill heat treatment can also change the ball mill surface CuZhuo degree,Cone crusher manufacturer and effectively remove the electrical discharge machining and produce surface metamorphism.…
The transmission parts of ball mill mainly consist of gear box, small and big transmission gear, electric motor and electric control panel. During the working of ball mill, the sound of gear box running should be smooth. If the wheel gear sounds slight beat or hoarse friction voice, and run well, you can observe continuously and find out the problems, ball mill should be stop and process; if the sound becomes louder, you should stop the machine immediately and check it.…
The working efficiency directly affects the concentrator economic benefits of the beneficiation factories. Therefore improve the efficiency of the mill is very important. Generally speaking, the factors restricting the improvement of the efficiency as following: 1. The electric current For ball mill, enlarging the current is to increase the rotate speed. If the has high rotate speed, its work efficiency will be high. However, there is one notice: the increased current should be within the scope of the rated power range. Otherwise, it will burn away ball mill. 2. Ball stone Here it is very important to collocate the diameter of the ball. To make fully grinding the different size of ores, it demands different sizes ball stone. And then it can improve the ball mill working efficiency. 3. The formula of raw materials Reasonable selection of formula can not only improve the intensity of ball, but also increase its weight. Consequently, the formula can increase its inertia, to improve the working efficiency of the ball mill. 4. Reduction gear To improve rotate speed play an important role in improving the work efficiency of ball mill. Therefore, the appropriate improvement for reduction gear also can take effect. The factory can choose to install inverter to adjust the rotate speed, which is benefit to achieve satisfactory results. 5. Water added The moisture in the ore has something to do with the ball mill working efficiency. Therefore, help the ore in the mill cavity moisturize also can improve the ball mill working efficiency. 6. Dispersant To some extent, putting dispersant into the ball mill can improve its working efficiency. As a professional in Shanghai Zenith, has 20 years of production experience, advanced ball mill technology, strong technical, reasonable ball mill price, and welcome consumers to visit consultation.…

A typical type of fine grinder is the ball mill. A slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grinds material to the necessary fineness by friction and impact with the tumbling balls. 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. Ball mills are commonly used in the manufacture of Portland cement and finer grinding stages of mineral processing. Industrial ball mills can be as large as 8.5 m (28 ft) in diameter with a 22 MW motor, drawing approximately 0.0011% of the total world's power (see List of countries by electricity consumption). However, small versions of ball mills can be found in laboratories where they are used for grinding sample material for quality assurance.…
Mining enterprise should introduce the mature technology and production and then build the domestic brands with independent intellectual property rights on the basis of independent research. Nowadays, the latter way is the trend of domestic mining industry. Hongxing Company has many special technical designs in high frequency screen. Two vibration motors are installed horizontally. One is installed on the top of the other one. Unbalanced gravity produces rotary effect, makes the screen work stably, embedded screen mesh, easy to install and partial replace our multi-frequency screen adopts unique design, we can get unexpected effect when combined with high-efficiency thickener (deep corn, multi-cone). Large capacity;remarkable technical and economic effect; vibration devices use rubber buffer, suitable for bad working conditions, reduce the iron pollution, more suitable for nonmetallic, wet metallurgy and nuclear industry. The series screen machine works in a re-circulating network with ball mill, which can upgrade the fineness of ferrous and nonferrous metals. Its efficiency is twice that of spiral classifier. It adopts the high frequency and low amplitude vibration for the processing of powder in coal, metallurgy, electricity, construction and chemical industry.…
Here we mainly discuss about the two-level graduation way of grinding ball. We use two kinds of steel ball with different specifications and one is large in diameter and the other is small in diameter. Its theoretical basis is that the small balls fill in the gaps between big ones to fully improve the bulk density of the steel ball. On one hand, it can improve the impact force and times of the first chamber. On the other hand, high packing density can make materials to be grinded well.…
In rod mill, electrical machine is using reduction gears and under drive gear, or low speed synchronous motor is using the under drive gear directly, to drive the barrel rotating. The product particle size of rod mill is more uniform than that of ball mill; however, the product granularity of ball mill is smaller and finer. The particle size distribution accumulation of ball mill is more efficient than rod mill.…
