Ball Mill Control Theory and Application

Filed under: Uncategorized — Tags: , , — sbmzhcn @ 2:28 am

Note: Cross posted from sbmzhcn.


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)


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.

Crusher working principle and advantages of an overview analysis

Filed under: Uncategorized — Tags: , , — sbmzhcn @ 2:07 am

Note: Cross posted from sbmzhcn.


I. Impact Crusher  Work The name suggests, Impact Crusher is used to achieve the crushing effect of counter-masterpiece, and in large materials into the counter board and after the crushing chamber between the rotor by rotation of the rotor part of the role of access to kinetic energy in the counter plate and the rotor repeatedly between the impact of each of the two first-class counter-cavity, the second-level counter chamber and the bottom of the grinding chamber of progressively broken, meet the requirements of the expected size.

II crusher  hammer crusher compared with the technological advantages of
1. Able to handle large moisture content of materials, to prevent clogging crusher
Excessive water in the processing of materials, the impact crusher the feed chute and the counter plate can be equipped with heating devices to prevent the bonding material. Impact Crusher is no need with the bottom of the sieve can prevent clogging. The hammer crusher can not be used heating methods to prevent adhesion of materials, and should be equipped with the bottom of the sieve plate, increasing the possibility of blockage.

2. Impact Crusher is suited to the soft material has applied to the material hardness of very large

Board crusher hammer strong mechanical clamping structure is scheduled for the rotor, when the rotor rotates with great inertia. Relative to the hammer crusher (hammer was hanging state), impact crusher rotor has a greater momentum, to adapt a more rigid material broken at the same time, lower energy consumption.

3. Can facilitate flexible adjustment of the particle size, wide tuning range
Counterattack breakers are many ways to adjust the particle size, such as adjusting the rotor speed, conditioning and grinding chamber counter plate and gap. Gap adjustment can be mechanical or hydraulic adjustable, hydraulic adjustment system can easily operate the button or fortune through the local control system to complete the gap adjustment. The hammer crusher adjust the particle size can only be achieved by replacing the bottom of the sieve.

4. Consumable wear little more than hammer crusher, metal high utilization
Impact Hammer wear only one side in Looking materials. When the rotor speed is normal, the feed will drop to the plate hammer surface (of attack), hammer on the back and side panels are not being worn. Even Looking material this side very little wear. And the bottom of the grinding rod is also very easy to replace. Impact Hammer metal utilization up to 45%? 48%. The hammer crusher hammer was hanging state, the wear occurs, the front and rear and side, relative to the plate hammer, hammer wear more serious, hammer metal utilization ratio is only about 25%. And the rotor body itself may also be worn. Hammer crusher wear badly affected by the bottom screen, grille to replace all, and replace the sieve of the work more complicated.

5. Easy replacement of spare parts, less maintenance costs
Crusher rotor only hammer to install six panel, using special tools provided by the plate hammer easily replaced, the replacement of a board of only one frequency hammer time. The bottom of the rod mill grinding chamber also requires only the replacement of dozens of minutes, greatly reducing maintenance and maintenance time and costs. The hammer crusher hammer up to 100 only, changing to a hammer a lot of time and manpower, repair and maintenance costs higher. Replacement of the bottom screen is also extremely cumbersome. Fortune

above content is based on years of experience in production machinery and customer feedback, summary income information purposes only. Although the impact crusher with high technical advantages, but when you select the crusher is recommended that you first expert advice, depending on your situation to choose the most suitable crushing machine (such as jaw crusher, hammer crusher , impact crusher, etc.), lower production costs.
