Coal Mill and Ball Milling Machine

Filed under: Uncategorized — Tags: — sbmzhcn @ 1:22 am

Coal mill used at coal fired power plant
In coal fired power plant, coal mill and ball mill is used to grind, pulverize and dry coal before the coal is transmitted the boiler. The coal is feed into the coal mill via a inlet pipe so that the roller coal mill such as Raymond mill and vertical mill can pulverize the coal into particles.

The hot air in the coal mill will lift the coal particles out of the Raymond mill or vertical mill and into the boiler, if the coal particles are too heavy they will drop to the bottom of the coal mill too and will be grind, pulverize again.

The coal flow into the boiler is an important factor for a coal fired power plant. But in fact, it is not easy to measure the coal flow from the coal mill to the furnace. The coal flow out of the coal mill is often estimated based on the incoming coal flow.
Coal milling plant for coal mining

Usually we grind coal into powder to improve the using efficiency. This way is common in Electric Power Plant. In this milling process, coal mill plays an important role.
Coal mill has many kinds, such as ball mill, raymond mill, vertical mill, ultrafine mill etc.
Ball mill is most widely used coal mill. It is suitable in the powder plant, and widely used in powder-making production line including cement, silicate, new-type building material, refractory material, fertilizer, ore dressing of ferrous metal and non-ferrous metal, glass ceramics, etc. It is divided into two rubbing way-the dry and the wet. There are two kinds of ball mill, grate type and overfall type due to different ways of discharging material. The ball mill is a key equipment to grind the crushed materials after the material were broken , and carrying on the smashing again.

ball mill liners are mostly made of metal materials, but also a small amount of non-metallic materials. In addition to protect the cylinder liner cylinder, but also the movement of the grinding law of impact, in order to adapt to different working state (crushed or broken bits) requirements, lining the shape and material are also different. When the order to crush the main, require the lining of the grinding capacity of a strong elected body, while lining should have a good fighting performance. High manganese steel ZGMn13 have sufficient impact toughness, and dealt a blow when it is able to work hardening the surface becomes hard wear-resistant. Therefore, the main crushing mill cylinder liner are mostly high-manganese steel manufacturing.

Where the finely ground-based, the lining of the highlights on the relatively small body elected to the ground on the weak, the impact is smaller than strong abrasive. Require lining has a good wear resistance. Domestic mill mainly used for fine grinding cylinder liner materials are generally wear-resistant white iron, chilled cast iron, ductile iron and other rare-earth manganese. In recent years, widely used in rubber liner. Shape rubber lining rubber layering generally peaceful lining of two parts.

According to the working state of the different mill, rubber lining of the bead is also made to be corresponding to different shapes in order to change the tube mill grinding body in the law of motion.

Vertical Mill is a kind of large scale powder mill which is designed specially to solve the problems of low capacity and high consumption of industry mills. With a decade of years research of mills, vertical mill is designed and manufactured based on our advanced design idea, and in combination with the european technology and the market demand. LM Vertical Roller Mill adopts reliable structure and reasonable process flow, integrated with drying, milling, classifier, elevator. Especially, it can fully meets the requirement of clients in the high production of powder, and its main technical and economy indicator reachs the international level.

Raymond mill is the early coal mill, all the finished particles have a good uniformity of finess, with passing screen rate as high as 98%. This is what other machine can not reach.
Ultrafine grinding mill is a equipment which produces thin powder and super thin powder. It will highten pollution and noise by using deduster and muffler, which achieves environmental protection requirement.

1 The principle of automatic control system for milling process overview

Automatic control of the ball grinding mill powder size of purpose is to control the ball mill, the possible to improve the quality of products of powder. Using the computer control system of the grinding technology can improve the productivity, improve the control accuracy.

1.1 The principle and operating characteristics of ball mill

Usually the ball within a ball. Wall lining has wavy manganese steel armor of cylinder. Cylinder side as raw materials imported and wind blowing on the other side of the import, export for gas mixture of powder. The motor and reducer cylinder rotate speed, turning device with centrifugal and polishing in under the action of forces, armor will ball and raw material up to a certain height. Then use gravity free fall. Raw materials are mainly ball shatter, but also affected by steel ball and armor between, between the extrusion and grinding. A good FenZi grinding materials, mixing system into the next procedure. For running after a ball. Noise signal, the population pressure difference and relationship between output (see figure 1)

ball-mill-work

When the ball when the increase in quantity. The increasing power of ball mill, but until the noise signals, basically is found by large slope down. With the increasing of quantity of ball mill, export differential pressure also slightly increased. When feed greater depth. Differential pressure is rising sharply.

According to the curves shown in figure 1 characteristics can be seen. The noise signal is ball mill can reflect the quantity of materials. In the ball speed constant, the ball is a certain period, by measuring the grinding machine, the noise signal can be directly within the ball mill detection of materials. Therefore, the stability of the grinding machine for shoes. Control air purging, make their relationship, it can control the equilibrium of the grinding mill.

1.2 Difficult to control the ball milling

1) from its existing mill run characteristics. Noise is a variation of parameters, it is significant for mill materials. But because the ball inside the operating conditions of complex and measurement methods have greater error. So the control scheme in composition may have some limitations.

2) the grinding mill control system is more people, more than the output variables and strong coupling, large inertia, large delay of time-varying system. Using common PID control force lacerates the relationship between the variables. Not only get better effect, but also is caused extremely easily system stability.

3) the grinding ball control, except for shoes, accused of parameters for air outside disturbance. Also, the grain size ball and the effect of water content.

2 Grinding process is sub

General grinding system operating first kind is to use of ball mill for export pressure difference control parameters, the second kind is to use manual operation. Depend on the experience, the operator control over two methods, the existing control precision grinding low volatility of particle size, quality and yield of grinding is difficult to control. The quality of products.
Two of the automatic control system

Control system is composed of two parts, hardware and software are introduced as follows:

2.1 control system software

The software is used to control strategy of human-simulated intelligent control scheme. It is based on the principle of intelligent control, imitation of man’s thinking on intelligent decoupling, ball mill in order to ensure the safe and reliable operation, the software is the core logic by intelligent controller and intelligent algorithm.

Intelligent design according to the logic is running the operation experience, according to the input error and its variation formulate corresponding control strategy, the principle is: (1) the noise signals according to the ball, adjusting control of disc feeder under shoes. Make quantity to achieve stability.

(2) adjust air control two loop baffle, its balance. Intelligent algorithm according to the ball mill system controller is the coupling, the controller can be divided into three sons, each loop circuits using intelligent algorithm based on the input, and the changes of choose corresponding algorithm and achieve the purpose of humanoid control.
