Cement clinker is usually ground using a ball mill. This is essentially a large rotating drum containing grinding media - normally steel balls. As the drum rotates, the motion of the balls crushes the clinker. The drum rotates approximately once every couple of seconds.The drum is generally divided into two or three chambers, with different size grinding media. As the clinker particles are ground down, smaller media are more efficient at reducing the particle size still further.
To use the dry Ball Mills the material to be ground is loaded into the Neoprene barrel that contains grinding media. As the barrel rotates, the material is crushed between the individual pieces of grinding media that mix and crush the product into fine powder over a period of several hours.Quite simply, the longer the dry Ball Mills runs, the finer the powder will be. Ultimate particle size depends entirely on how hard the material you're grinding is, and the time how long the Ball Mill runs. Our Ball Mills have been used to grind glass, powder food products, create custom varnishes, make ceramic glaze, powder various chemicals, and make Black Powder.
a. Common Cement Mill It is mainly used in cycle grinding system, with features of high grinding efficiency, high production, low power consumption. Especially, when grinding slag cement, its performance is more outstanding. Generally speaking, production could be 10-20% higher, and power consumption 10% lower. Besides, product temperature could reduce 20-40and product fineness is easy to adjust.
b. High Fineness & Production Cement Mill It is mainly used in open flow grinding system, with features of simple equipment system & process flow, saving investment, less building area. Regarding structure, it has advanced & special material separating diaphragm device inside, adds activation device to fine grinding chamber, and has discharging grate plate at mill outlet, thus to reduce the size of grinding media at the most and promote the grinding efficiency highly, realize the purpose of high production & low power consumption.

Ball mill is used to grinding ores or other materials after crusher, it is the mechanical equipment for getting finer particle products.
Classification of ball mill:According to service conditions, ball mills can be divided into wet ball mill and dry ball mill. According to the structure,ball mills can be divided into grate type ball mill and overflow type ball mill.Material from the feed device into the mill warehouse, there are ladder liner or corrugated liner in the warehouse, built with different specifications grinding balls, to make the positions of the materials and grinding ball mill evenly distributed, to avoid starting difficulties due emphasis cause mill, it required start auxiliaries when feeding, the process is also known as swing mill. Subject to material evenly distributed in the warehouse after rotating cylinder produces centrifugal force grinding balls taken to a certain height After the fall, have severe impact on the material and abrasive. Powder is discharged through the discharge device, complete the milling operation.
Ball Mill Working Principle:
Materials from drum type hopper enter the mill through the hollow shaft spiral shell. The mill has grinding mediums in the shell. When the shell rotate,grinding mediums attach to the shell’s inside liner because of centrifugal inertial force.After rising to some height with ghe shell, the grinding mediums free fall down because of gravity, and this will crush the materials in the shell.
With the increasingly fierce market competition, how to save energy, reduce production costs, are all issues of common concern enterprises, therefore, to minimize the power consumption of the ball mill, energy conservation, to improve the economic efficiency of enterprises has important significance.
the existing ball mill starting mode and the control mode is not saving, though frequency transformation can save a lot of electricity .start mode when the existing ball mill force of the impact is very large, so the ball mill bearings and gear reducer easily damaged, repair costs big.ball mill using existing Starting inrush current when starting a large ball (usually rated current 7 to 8 times), will cause voltage fluctuations, voltage drop, can also cause severe tripping and other equipment failures, affecting the normal production.

Conveyor belt (conveyor belt) is the materiel transporting machine which transports the materiel in a certain line. It is the key equipment in conveyor belt system. Conveyor belt also can be named elevating conveyor belt. The belt conveyor can carry horizontal, oblique and vertical transporting and also can be composed into a space conveying line. Then we will introduce the commonly used devices in this system. We should pay attention to the size of the installation accuracy and daily maintenance. Hongxing Machinery introduce the reasons of deviation of belt conveyor running, we need maintenance according to the different reasons for the difference way.
1. The adjustment of stretch joints. Belt conveyor was running a very important link in the process of partial adjustment. Two upper heavy hammer stretch joint redirection roller besides belt length should be perpendicular to the direction should be perpendicular to the gravity vertical, which ensure the shaft centerline. Using spiral tension or hydraulic tensioning oil cylinder, the two tension roller bearing should translation at the same time, to ensure that the cylinder axis and the vertical belt longitudinal direction. The specific belt runs deviation adjustment method and the roller of similar.
2. Adjust the driving drum and redirection and haul driving drum position adjustment is an important part of the belt running deviation adjustment. Because of a belt conveyor are at least two to five drum, drum of all installation location must be perpendicular to the centerline of the direction of the length of the belt conveyor, if excessive deflection must be wandering. The adjustment method is similar to roller group. To head to the right side of the drum, such as belt running deviation, the bearing should move forward, on the right side of the belt to the drum of the left side of the wandering, is on the left side of the bearing should be moving forward, can also be on the left side of the corresponding bearing seat back or on the right side of bearing seat back. The tail roller adjustment method is contrary to the head roller. Best before adjusting drive or redirection roller installed its position accurately.

A Cement Ball Mill is the equipment used to grind the hard, nodular clinker from the Cement Kiln into the fine grey powder that is cement. Most cement is currently ground in Ball Mills.The Cement Mills on a cement plant are usually sized for a clinker consumption considerably greater than the output of the plant's kilns.
Regardless of the type of mill, we call it as gravel crushing mill which crushing material use siliceous gravel for media. The ceramic ball is not commonly used except some particular situation. The machine is often used for grinding cyanide treatment of gold ore, because in this process, the iron which produced by iron ball and liner lapped each other is harmful. In that case, using ceramic liner or embedded gravel regular in cement of the mill’s interior. The machine is mainly used for grinding mineral ore which is afraid of iron pollution and processing gold and silver ore. Gradually in recent years, the ceramic ball machine has large development and application.
Ceramic ball mill are low-speed heavy equipment, loading capacity, is also a great starting torque, the Ceramic Ball usually add the impact of start or soft start motor starter to start, the impact of large power grid, and start running after the completion of the required The turn away from reduced, so saving energy has a lot of space. In order to overcome the uncertainty of model parameters and disturbance of system, robust control algorithm for ball mill system is researched. For the load control loop, based on the difference pressure control loop, the fill level control loop is imported. By choosing proper weighting function, a cascade robust control algorithm is proposed based on H, mixed sensitivity theory. For the coupling loop of inlet negative press and outlet temperature, the decoupling problem and mixed sensitivity problem design is combined. An H robust decoupling algorithm is proposed.

Why Ball Mill play an important role in beneficiation industry? Let us tell you the reasons. There are plenty of grinding methods in grinding industry. While ball mill can be applied to grind all kinds of ores and other materials, and it is commonly used to grind building material, chemical industries and beneficiation industry.
According to different ore discharges, ball mill can be divided into Tube ball mill and Overflow Type ball mill. The ball mill is made from feeding department, discharging department, rotary department, reduction gear, small transmission gear motor, and electronic control. Hollow shaft adopts steel castings inside; rotary gear wheel adopts hobbing to process its rotary and process wear-resisting board. By this, the gear has abrasion performance, and works smoothly.
All pulverizers common feature is: milled parts are by the relative motion of the two parts,Grinding coal to the surface in between the two groups, under the action of the pressing force by the extrusion and milling have been crushed.At the same time, the hot gases pass into the coal mill drying, and sifted through a mill grinding of coal brought to the upper part of the separation device in the area.After separation, the coarse particles which return to repeat the grinding mill area, fine coal powder will be taken out of the mill by still air.
Rotating disc in the drive this type of mill spindle are vertical, so it is said 'vertical shaft mill'.Spindle speed range between the low-speed grinding and high-speed mill, medium speed coal mill will be hence the name. As a leading enterprise of mining machinery manufacturer of China, our company has strong technical force and powerful production capacity and can produce aggregate crushing, cement equipments, chute feeder, compound cone crusher, flotation machine, etc.

Most cement is currently ground in Ball Mills.The Cement Mills on a cement plant are usually sized for a clinker consumption considerably greater than the output of the plant's kilns
Adding the dispersant can raise the ball mill efficiency by some extent.
For ball mill, boosting current can raise the rotating speed which will improve the ball mill efficiency in turn. But we should make sure the boosting current is within the power rating rang. The over-strong current will burn the ball mill.
How to match the sphere diameter is also very important. Make it of various shapes so that the ore in the mill intracavity with big ones and small ones together can be milled fully. Thus the ball mill efficiency can be raised.
Raw material ingredients
Only choose the proper ingredient can improve the ball’s strength and weight, thus enhance its inertial property, and finally raise the ball mill efficiency.
In order to overcome the uncertainty of model parameters and disturbance of system, robust control algorithm for ball mill system is researched. For the load control loop, based on the difference pressure control loop, the fill level control loop is imported.

Ball mill is the key equipment for the material being broken again after crushing. The series of Ball Mill is widely used in grinding clinker, carbonate, fireproof stuff, and chemical materials, also can be used inBeneficiation industry to grind the ores before selection. It can be divided into dry grinding and wet grinding. The advantage of overflow type Ball Mill are that it’s simple structures and easy to maintain. As the outlet pipe has reverse threads inside, large ores and steel balls are not easy to be discharged outside. The disadvantage is that it’s low production capacity per unit volume and as a result, it has low processed volume and easy to have over-crushing.
All pulverizers common feature is: milled parts are by the relative motion of the two parts,Grinding coal to the surface in between the two groups, under the action of the pressing force by the extrusion and milling have been crushed.At the same time, the hot gases pass into the coal mill drying, and sifted through a mill grinding of coal brought to the upper part of the separation device in the area.After separation, the coarse particles which return to repeat the grinding mill area, fine coal powder will be taken out of the mill by still air .

Rotary dryer equipment is a main energy-consuming machine so that we should try our best to make it reach high quality, low energy consumption, and high output. The rotary dryer is slightly inclined cylindrical shells supported by 2 riding rings running on a set of rollers. In the drying machine working time, the drying effect influence by many factors. The influencing factors have six terms. Let Hongxing Machinery experts share these factors to us.
1. Hot blast heater
At present there are three types of hot blast heaters that are widely used in cement plants. In the production process, the customers should choose blast heater with high heat efficiency and stable operation according to the local resources.
2. The structure and property of the materials
As materials with different structure and property will have different combination modes with water; and on the same drying condition, the drying efficiency will be different.
3. The operation of the drying equipment
The stable operation temperature will be conducive to the implementation of the drying process. If the heat supply is not stable, the heat efficiency will be low.
4. The feeding granularity and the uniformity of the material feeding
On the condition that the drying speed is definite, the bigger the contact area of the materials and the hot air is, the better the total drying effect will be.
5. The temperature of hot air
The higher the temperature of hot air is, the higher the rate of heat transfer and mass transfer will be; and on the condition of the same moisture evaporation capacity, the amount of hot air can be reduced, which will reduce the waste air hot loss. However, at present the temperature of the inlet hot air of the dryer machine used in many cement plants is very low, and even the temperature of downstream drying equipment is only about 700℃, for this reason, in a permitted range of the cylinder, greatly improving the inlet temperature of the hot air is not practicable.
