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.

ball mill

2.2 control system of the hardware

Control system hardware consists of: PLC and computer, isolation and transducers, inverter, noise and transform device, flowmeter, electric baffle valves, electric butterfly valve, pressure transmitter such equipment. A new form of the control system can fully test the key parameters of grinding process, through these parameters to PI C and computer provide enough information to control system, comprehensive treatment, and to form a correct judgment, provide accurate control signal, make grinding system according to the requirements of control in advance to work.

Ball Mill  is an efficient tool for grinding many materials into fine powder. Ball Mill is used to grind many kinds of mine and other materials, or to select the mine. It is widely used in building material, chemical industry, etc. There are two ways of grinding: the dry way and the wet way. It can be divided into tabular type and flowing type according to different expelling mine. To use the Ball Mill, 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 Ball Mill 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.

how the ball mill works

1、A preface

Since in 1880 in industrial production ceramic grinding materials used since the ball more than 100 years history, despite a few advanced countries due to material technology development and only used in ceramic production only plays the ball mill ingredients (mixed), but most of the countries in ceramic production is widely used for grinding mill with mixed casting glaze ceramic raw materials, and paints. However, the efficiency of the ceramic production of ball mill is lower — about 1 %, so that a large amount of energy consumption. According to statistics, ceramic production in about 40 percent of the energy consumption in the ball grinding process. The ball mill process of material of particle shape and size distribution, the fineness, physical and chemical properties, production efficiency has important influence, this paper will be of ball mill process of related problems were discussed. The superficial

2 、the crushing mechanism of materials

Material in the ball mill process is shattered due to its body and abrasive abrasive results. However, the grinding process is extremely complex. If a single particles as research object, the ball mill process it may repeatedly by grinding compressive stress, which exists in the role of the particles on the surface of a new generation of inherent or expansion crack, and lead to its broken or plastic deformation. When the particles are constantly shattered. A certain level of new particles can be further ground, because the new particles on the surface of the crack, and appear a certain minimum fracture risk of crack stress reduced ACTS. When breaking process continues, the final for crushing stress could increase to make granules of plastic deformation degree. Now, with the plastic deformation, particle size is the will. Thus, when the materials are a grinding size limit. For raw materials, quartz can be ground for 1 micron in size limit, and as the extremum, limestone for 3 ~ 5 micron. That is, when the grinding materials into the scope of ultra-fine grinding mill, the effect was more difficult. In most of the grinding system has a real grind limit, this limit the main on grinding particles produced products, and the tendency to accumulate accumulate and broken up between the physical balance. Therefore, a long ball grinding extended time is meaningless, only leads to increased energy, because the meticulous grain can effectively storage needed to crack expansion of elastic energy.

The actual grinding process than the above discussion, the situation is much more complex particle surface crack expanding and new crack appear because each particle interaction among cracks, the sub-tissue particles interact with the wall, the function, the secondary role between particles and the effect with abrasive particles, particle physics and chemistry of the smell of particles and abrasive environments and aggravate, particle breaking. But, for the recognition of the essence of the visual sense or only on the basis of reasoning.
