Stainless Steel Tube Mills To Achieve A High Yield, Low Consumption Of Green Production

Jun 27, 2017

Stainless Steel Tube Mills  in the joint grinding system is often one of the most important aspects of how to play the potential capacity of the Stainless Steel Tube Mills  is the current goal of each cement worker to pursue. The original structure of the internal design of the mill is far less than the joint grinding process system engineering, the pipe mill on the process parameters of the request. To this end, the internal technical transformation of the mill is imperative. This paper introduces the technical transformation of the key parts of the mill mill with roller press, so as to better meet the requirements of the combined grinding and production system.

1) a warehouse liner configuration unreasonable. After the roller press + V-type separator system, the grinding material has been reduced particle size, 80μm sieve more than ≤ 23%, the main role of a warehouse is grinding, do not need to break. And a warehouse is used in the original ladder liner, ladder lining the main role is to enhance the grinding body, so that it has a certain potential energy, and thus the formation of impact crushing materials. This configuration caused a warehouse unit length grinding body work less, into the bin warehouse material rough.

2) compartment board design is unreasonable. Separate plate is used in the early development of the product, equipped with a blind plate, this form of compartment board easily lead to blockage, affecting the normal flow of ventilation and materials.

3) Grinding grate design is unreasonable. Grinding the grate plate block serious, affecting the discharge and ventilation.

4) grinding body grade unreasonable. Grinding body gradation adjustment should take into account the various materials of abrasibility, material size and material moisture and other factors, but the original level of the program failed to take into account.

The specific measures are: cut into the pipeline into the inlet pipe, do not allow any leakage material, straight into the mill a warehouse, the lower part of the mouth to the front of the block, up and down the left and right openings, the opening area of each face should be Cut pipe cross-sectional area is equal to the front block board should be in a warehouse, steel ball can not hit the place. This kind of cutting device to ease the impact of the expected material, the material can not suddenly rushed to the back of a warehouse, but also eliminates the grinding of a blind spot.

The former cast-type grinding tail grate plate into a combination of grate grate form. The grate plate structure is open in the original grate area, with the maximum cross-sectional area as the ideal value, using the sieve sieve as the final structure of the grinding grate, to meet the needs of the tail and the cross-sectional area. This kind of sieve grate combination grate plate, can solve the rear warehouse temperature is high, electrostatic paste grinding and grinding problem. To this end, the original grinding tail grate plate replaced HX-B anti-blocking type grate plate, to improve the grinding furnace ventilation and material flow rate.

Adjust the grinding machine gradation according to the new technological conditions. The grinding grade should be calculated according to the abrasibility of various materials such as clinker and mixture. For different grinding systems, the corresponding gradation plan should be taken. In the trial production, the production data must be calculated according to the production data Surface area, sieve residue and working current, etc.) for real-time adjustment, and finally find the best gradation.

After the above transformation and adjustment, the operation of the combined grinding system has been greatly improved, Table 2 is the transformation and adjustment of the actual operating data. Table 2 shows that the production of P · C32.5R cement system output reached 195 ~ 200t / h, cement integrated power consumption can be reduced to 25kWh / t, production P · O42.5 cement when the output stability in the 180 ~ 190t / H, product specific surface area and sieve to meet the control requirements, unit cement production power consumption greatly reduced. To achieve a high yield, low consumption of green production, a substantial increase in economic efficiency of enterprises.

Determine the quality of the mill factors in addition to the system configuration, and operational philosophy, grinding body gradation also has a great relationship. The technical transformation of the structure of the mill mill only provides a prerequisite for the production, durability and consumption reduction. Mill ventilation effect is not good, no matter how good the grinding body gradation also play a role. Reasonable grinding within the configuration, can improve the working conditions within the mill, thereby greatly improving system production and reduce the power consumption of grinding. HX-C surface liner, HXB grinding tail grate plate, HX-G compartment plate series of grinding equipment design is reasonable, to improve the grinding ventilation, control the material flow rate play a decisive role. Pipe mill capacity up, and the joint grinding system will solve most of the problems, and then do a good job of roller press system transformation and commissioning work, so that it does not affect the Stainless Steel Tube Mills  energy, if it is double closed system, but also to transform And debugging good grinding tail powder selection efficiency, so that the combined production of grinding system to play to the best quality.
