[Improvement]: The jack-up device adopts the hydraulic jack-up device independently developed by Xinhai. When the ball mill is in maintenance, only handling the hydraulic station can make the hydraulic jack rise and fall. Compared with the ordinary jack-up device, Xinhai jack-up device is simple, convenient and easy to operate with lower maintenance costs.

The main component is a cylinder with diameter and length at a reasonable proportion. Driven by the transmission device, the cylinder rotates with the materials fed from the cylinder inlet and crushed by the falling impacts and autogenous grinding of the steel balls and ores in the cylinder. Due to the continuously feeding materials, the pressure pushes materials to the outlet and the grinded materials are discharged from the cylinder outlet. Qualified materials flow from the cylinder outlet. In wet grinding, the materials are taken out by the water flow.

The grinding operation is directly relative with the capacity, economy and technology indexes of processing plant. The grinding equipment also has a large proportion of mineral processing plant construction and production cost. Therefore, energy-saving, low consumption, and high efficiency are the most important things to consider in grinding operations.

Over 200 manufacturing workers for mineral processing equipment in two production plants manufacture ball mill with automatic welding manipulator, vertical lathes of various models, and hobbing machine.

Xinhai MIning can customize various aspects of ball mill to combine with processing technologies perfectly, improving production rate, reducing energy consumption, and extending equipment stable operation period.

The damage and losing efficiency most appear in the wear, agglutination and corrosive pitting. The main reason is weak lubrication. Therefore we suggest deploying large and small gear spray lubrication system for ball mills over 27.

It is the lubrication system designed for large and small gears. The dry oil or thin oil are atomized and spray on gears by compressed air and form meticulous and even dry oil film, which can easily reduce the force of friction and save energy. When the oil foam forms, it is among the liquid friction zone and reducing force of friction.

The bearing is double row t aligning roller bearings from national famous brand replacing sliding bearing. It deploys labyrinth sealed rolling bearing and linear contact. The friction force is much less than sliding bearing face to face.

Every kind of ball mill design has its own bearing. After the simulation analysis of the stress, total displacement, deformed shape, and safety deformation coefficient, the model bearing is determined whether it is suitable for the ball mill model or not.

The synchronous motor is over 400kw. Professional TDMK slow synchronous motor connects little gear through pneumatic clutch to realize single-stage reduction transmission and driving the rotation of cylinder.

Slow transmission system can provide convenience for ball mill overhaul and liner changing. If the shut-down period is over 4 hours, it is hard to start for the material consolidation in cylinder. Slow driving jigger before turn on the main motor. It can loose the materials and convenient for main motor turning on.

Realizing reduction voltage starting uses winding motor time-frequency start cabinet or liquid resistance start cabinet. It can reduce the attack to power grid. Current and torque changes during turning on motor.

The hydraulic jacking device is mainly made up with hydraulic jack and hydraulic station system. During the maintaining of ball mill, the hydraulic jack lifting is controlled by hydraulic station hand shank.

(1)For middle and small ball mill design, Xinhai deploys overall rack for ball mill. The ball mill is installed on an integral welding frame. The ball mill installation and commission can be accomplished in factor. Just put it on the pre-made foundation at the scene, and find the level and install it firmly. It reduces the engineering quantity and working period, and also convenient for the long-term transportation of equipment.

Ball mill grinder is the essential equipment in mineral processing plant, which is also the key equipment in the whole mineral processing plant construction. Therefore the stable operation of ball mill is essential. However, before the official putting into operation, the commission of ball mill grinders is important. A little mistake would lead to the unqualified particle size in products, even reducing the metal recovery rate. How to carry out the commission of ball mill grinders? In this passage, we will introduce you to the process of ball mill grinder commission.

Ball mill grinder installation accomplishment according to the paper, to ensure all the components are at the right position. The complete installation process should be recorded and acceptance passed.

The bush should be installed on the sector block of lower bearing seat according to the rotation direction of ball mill. The bush should be revised according to the axial guide ring. The bearing seat seal should be installed correctly. The junction should be sealed by a sealant.

Ensuring that all the monitoring equipment are well-connected. The flow monitor, pressure switch and temperature sensor are set well. Oil pressure gauge, thermometer, accident button and interlocking device instructions are reliable.

Connecting with reducer and pinion coupling, and installing protecting mask. Start the lubricating oil system and cooling water system. Turn on the power of the ball mill, press the accident button to stop it, and check the main bearing, motor, and gears to determine whether the direction of rotation of the ball mill is correct. If there is no abnormality, start the ball mill to run for 8 hours.

When running empty, if the lubricating oil system is working normally and there is no oil leakage. The ball mill runs smoothly and there is no obvious noise. The vibration value of the main bearing, motor, and pinion does not exceed 0.1mm, and there is no obvious damage or hot phenomenon to all parts. The empty vehicle runs normally.

According to the ratio of ball mill, a certain amount of steel balls are added into the cylinder of ball mill grinder. Steel balls are added in batches. During operation, measure bearing temperature, current, and vibration intensity everywhere. After the installation of the ball mill is completed, start to run with load, add 70% of the specified load into the grinding material, and continue to run for more than 10 hours. During this process, the liner bolt joint should be fastened and check the bolt connection frequently to prevent the loosen.

During running with load, the ball mill grinder should satisfy the following requirements. The vibration of each part does not exceed 0.1mm; The current of the motor has no abnormal fluctuations; The running process is stable; The noise is small; The connecting bolts are tight, and the cylinder has good sealing.

The above is the whole installation and commission process of ball mill grinder.

In mineral processing, to make valuable ores realize single separation, ores must be crushed and grinded into powdery materials. In the process of crushing, all kinds of crushers are used, while a variety of ball mills, rod mills andautogenous mills(or semi-autogenous mills) are available in the process of grinding. Ball mills and rod mills take steel balls and steel bars as their medium, but on the contrary, autogenous mills make ores themselves be a medium. An autogenous mill is featured by combining mid-fine crushing with coarse grinding. Ores can be crushed and grinded through mutual impact and grinding with themselves as grinding media. This machine can produce -0.074mm ores which accounts for 20%-40% of total amount. The comminution degree can be 40005000, ten times higher than ball mills and rod mills.

Before in the 1950s, conventional autogenous mills was still in the stage of small specifications, low production and low efficiency. Till the 1960s to 1970s, it started up large-scale development. However, due to the limitation of structure, the processing capacity of the unit power consumption is low. As a result, it had not been widely used due to the large volume and difficult transportation.

After reform and openness, with rapid development of mining construction and technical advancement, autogenous mills are widely used. In recent years, we have been devoting to lowering energy consumption and improving grinding efficiency and utilization. Xinhai superfine lamination autogenous mill is a representative of new autogenous mills.

Xinhai has improved its structure. The transmission slowly rotates and materials are fed in from one side. Then, the ores are crushed by action of its own impact and autogenous mill in the cylinder. Those qualified materials are forced to discharge through the grizzly screen by action of overflow water.

This machine has remarkable discharging effects. Under the circumstance that maximum particle size is 160mm. The particle sizes are as follows: -200 mesh accounts for 45%; +200 meshto 2mm accounts for 45%; -2mm6mm accounts for 8%; +6mm10mm accounts for 2%. With 217.39% processing capacity of conventional ball mills, the products(-200 mesh for 45%) enter for classification and skip ball mill and directly enter next processing stage. During the feeding process of ball mill, ore liquid of +6mm10mm is less than 2%, and the rest is eligible +200 mesh6mm. In addition, this machine is energy-saving and environmental, featured by saving civil investment and floor area, shortening the construction cyclone and saving 60% power consumption. Thus, the processing capacity has been greatly improved.

The materials are uniformly sent to the first chamber of dry ball mill by the feeding device through the feeding hollow shaft. The first chamber of dry ball mill contains stepped lining board or corrugated lining board, and steel balls of different specifications. The centrifugal force generated by the cylinder rotation will bring the steel balls to a certain height and then drop down, which will have a pounding and grinding effect on the materials. After the rough grinding is finished in the first chamber of dry ball mill, the materials will enter into the second chamber through the single-wall partition, which is lined with flat lining board and steel balls to further grind the materials. The powder material is discharged through discharge grates, then the grinding operation is completed.
