Change the internal structure to improve the yield of energy-saving ball mill
Date:2014-10-09 09:22 From:Bailing Machinery Author:admin
Energy saving ball mill is a horizontal cylinder rotating device, outer gear, two warehouses, material from the feed devicefeedair evenly into the mill screw shaft first warehouse, the warehouse has stepped lining board or corrugated liner, built in different specifications of steel balls, rotating cylinder steel ball to a certain height to generate centrifugal force after the fall, the material produces severe impact and abrasive. Materials in the first position to coarse grinding, the board by the single compartment into the second warehouse, the warehouse linedwith flat lining, steel ball, the material to further grinding. Powder through the discharge grate discharge, finish grinding operation. Type, diameter, length, speed, internal structure and energy saving ball mill grinding body selection should be according to the material characteristics to determine in advance through the simulation test, the best to find out the best parameters. On the existing equipment, as the models, specifications have been identified, for optimization selection in addition to change varieties of materials, particle size, water points, mainly is the internal structure and the grinding body optimization, press the appropriate flow of materials.
1, strengthen energy-saving ball mill ventilation
Have obvious influence on Yield and quality of ventilation, energy saving ball mill in good ventilation, not only the fine powder discharged in time to avoid forming mill, over grinding, but also can take the grinding heat, reduce the temperature in the grinding, reduce the dehydration of gypsum and Okura ball blocking grate. You can enlarge the partition board and a center hole feeding grate plate and a discharging outlet air lock etc. to strengthen measures to improve through the improvement, the air vent, the feed inlet spiral at the material inlet feeding chute into a ladder shaped,, not only solve the clogging phenomenon, but also increase the ventilation area.
2, baffle plates and discharge grate
Sieving compartment plate is a novel partition plate can carry on the coarse and fine classification by partition plate material, its main role is to carry out screening on into fine grinding chamber material, prevents coarse particles into the fine grinding chamber, the use of surface micro grinding of large area, high grinding efficiency and create conditions for the fine grinding chamber, which is a novel partition plate not only increased the control of material flow and balance each storehouse smash the function of ability, and can achieve the classification of coarse and fine particles and enhance the function of material force, make early into the fine grinding chamber is grinding fine material.
3, the activation device
In order to give full play to the potential of energy saving ball mill grinding, grinding can also be added activation device, create conditions for the movement of three-dimensional micro media, strengthening the grinding ability, the kinetic energy to make the grinding body can more fully use so that the cm, greatly improving the grinding efficiency. Different requirements depending on the product, energy saving ball mill and axially arranged along the 2~5 Road, longitudinal and energy saving ball mill lining board every show will install a. Because of the role of activation device, grinding in grinding body in addition to energy saving ball mill lining board along the circular motion, but also for axial movement. At the same time, from the cylinder lining grinding plate far body because energy saving ball mill lining plate can not be effectively driven and retention area movement weakened due to activation of the role of the device can be eliminated.
4, liner plate
Lining board is the main dynamic distribution and motion trajectory is used to adjust the grinding body in addition to play a protective role, it forms to be matched with the energy-saving ball mill speed, material characteristics. Using a variety of new lining board, adjustment of the grinding body motion state and the adaptability of the material are greatly improved. Energy saving ball mill tail bin selection of hyperboloid lining plate, inclined surface in the axial and circumferential directions have, not only can increase the lateral and the ball, but also to improve the grinding efficiency of steel forging, steel ball.
Grading lining plate can make energy-saving ball mill in grinding body achieve the classification, the formation of large ball aniseed, the ideal state of small material ball.
