With the continuous development of science and technology, and now new technologies have emerged a lot of ball for different needs choose a suitable ball mill technology to achieve high yield, high-detailed, high-quality results. Henan Bailing Machinery Co., Ltd. let the following technical staff introduce the most common of several ball of the latest technological developments, including screening within the separator grinding technology, raw material drying air swept grinding technology, fine jaw crusher transform technology, the upgrading of separator technology, ball mill grinding system optimization.
First, choose a powder mill technology screening
At present, the domestic part of the high-yield, high fine, there is grinding screening screening screening device in the aperture plate large (2.5 ~ 3.5mm), through material size is small (only 30% of the material through area) easy to loose cause sieve materials Coarse, grate grate plate is easy to plug weaknesses, such as sewing. Cause users not to use the process to improve yield and quality of volatile, sometimes even to stop machine to deal with sieve and clean sewn grate grate plate, causing great losses to the user.
Choose a powder mill technology screening dozens of domestic high yield, high fine, sieve analysis and verification grinding innovative development, and a collection will Teng Kang grinding, high yield, high fine, screening grinding technology, and for the The above shortcomings were a major improvement. The technology and equipment used in the mill of new screening devices to the original grinding production process, considering all aspects of the production process systems, such as a clinker particle size, temperature, grindability, mixed materials types, water, etc.. Choose a sub-device through the role of the mill grinding process in a timely and effective separation of coarse and fine particles.
The technology the following features: diameter sieve plate screening device may be the actual situation according to the user within the 1.0 ~ 3.5mm design, sieve through material up to 40 ~ 65% area, easy to use process loose sieve, grate grate plate difficult to plug the gap. The production process can in the shortest time for two positions within the grinding of the particles separated from the warehouse, and to two positions in a timely manner within the grinding demands of particles from outside the mill.
Such a position of crushing and grinding two positions clearer division of labor, and had basically eliminated the grinding mill, and improve the mill's production efficiency; on the mill liner within the structure to optimize ball forging gradation adjustment, so that each device to achieve maximum system capacity; as ventilation capacity strengthening, through an area of increased material, grinding high humidity, high temperature material production to Taiwan when the far end of the general decline in high yield, high fine, screening mill; can increase production to Taiwan 20 ~ 40%, specific surface area can be controlled in the range of 300 ~ 450m2/kg; generally three months recoverable investment, the mill transformation of 1 to 2 days to complete.
This technique is suitable for closed circuit grinding, open mill, superfine slag powder transformation.
Second, raw material drying air swept grinding technology
Transformation of the raw mill closed in the raw material into the ground water can reach as high as 3.5% higher yield, a ф2.2 * 7m of the transformation of raw mill can cost thousands of dollars the bottom, grinding time in the general transformation not more than 24 hours to step down the same conditions can increase production of 20 ~ 80%.
3, fine jaw crusher modification technology
Is to use solid volume theory and principles and laminated materials according to the nature of fragmentation, size of the jaw crusher to optimize the design. The new E-board to make materials from entering the crushing chamber to be continuous extrusion and lower crushing chamber by a certain distance parallel to the extrusion. As the materials in the crushing chamber by squeezing the number of times the average crushing machine, so crushing efficiency greatly improved, the average particle size is only 5 ~ 10mm, and 30% of the powder. Apply the transformation only crushing jaw crusher jaw reconstruction costs need to invest and transform the time as long as 3 to 4 hours
A cement plant, clinker grinding stations Reconstruction of jaw crusher with the best choice.
4, separator upgrading of technology
Based on the original machine cyclone separator and centrifugal separator, considering the particle size distribution of cement is more reasonable, to cage-type rotor-type separator, after transformation to ensure the efficiency of raw material powder selected more than 70%; wear When the machine output increased by 10% to 40%. Clinker separator efficiency more than 55%; mill production to Taiwan increased by 5% to 20%; cement specific surface area increased 15 ~ 50m2/kg; particle composition improved early strength of cement has increased, and so on.
5, ball mill grinding system optimization
Grinding is the original production process, considering the particle size, temperature, mixing material types, etc.. The use of equilibrium theory, the mill, the 12 storage length, the mill had expected capacity of the ventilation system so other equipment to optimize the efficiency of adjustment so that the whole system and increase work efficiency and balance. Application of this technology is generally not required very little investment or investment, the yield increased from 10 to 25%.
