Reducing Raw Material Grinding Processing Material Consumption

Reducing Raw Material Grinding Processing Material Consumption

With the increasingly grim economic situation, various prices continue to rise, the company's profit margins are gradually reduced. In order to realize the sustainable development of the company, it is urgent to reduce cost and increase efficiency. As the medium-speed high-pressure Ore Milling Equipment is the main equipment for powder processing, reducing medium-speed high-pressure Ore Milling Equipment material consumption, the existing conditions to maximize the profit has become particularly important.

In order to reduce the consumption of materials, the company set up a research team of medium-speed and high-pressure Ore Milling Equipment, and the group is on-site type. Medium-speed high-pressure Ore Milling Equipment is the main equipment powder processing, the output is the company output 100%. The team integrates the company's management, technical staff and workshop production staff.

Team members on the high-pressure high-pressure Ore Milling Equipment workflow conducted on-site investigation and analysis of high-pressure Ore Milling Equipment and the Department of convergence Working principle: motor through the reducer drive disc rotation, the material fell from the feed port in the center of the disc, while hot air from Air inlet into the Ore Milling Equipment, under the action of centrifugal force, the material moves to the edge of the disc, the disc by the annular groove when the roller crushed crushed, the crushed material at the edge of the Ore Milling Equipment by the wind ring at high-speed airflow, large Particles fall directly onto the disc re-grinding, air flow through the separator material, the role of the rotor under rotation, the coarse powder fell on the disc re-grinding, qualified powder with the air flow out of two Ore Milling Equipment, the dust-collecting device In the collection, is the product.

Medium-speed high-pressure Ore Milling Equipment material consumption can be divided into medium-speed high-pressure Ore Milling Equipment and medium-speed high-pressure Ore Milling Equipment material consumption, we November 2011 to February 2012 medium-speed high-pressure Ore Milling Equipment consumption and High-speed Ore Milling Equipment material consumption statistics can be seen medium-speed high-pressure Ore Milling Equipment consumes 83% of medium-speed high-pressure Ore Milling Equipment consumption, medium-speed high-pressure Ore Milling Equipment consumption is medium-speed high-pressure Ore Milling Equipment consumption The main part of reducing medium-speed high-pressure Ore Milling Equipment consumption is to reduce medium-speed high-pressure Ore Milling Equipment material consumption more direct and effective measures.

In order to further understand the reasons for high speed medium-pressure high-pressure Ore Milling Equipment consumption, medium-speed high-pressure Ore Milling Equipment consumption can be classified machine speed medium-pressure high-pressure Ore Milling Equipment consumption it includes: ingredients system machine consumption, Ore Milling Equipmenting system Machine consumption, dust collection system machine consumption, warehouse system machine consumption. From the statistics of the four systems, it can be seen that the mechanical consumption of the grinding system accounts for 80% of the mechanical consumption of the medium-speed high-pressure Ore Milling Equipment, so the high mechanical consumption of the grinding system is the main problem.

We use two technical means to reduce the mechanical consumption of the grinding system by 30%, and the medium-speed and high-pressure Ore Milling Equipment consumption will be reduced by 83% × 80% × 30% = 19.92%.

To further determine the reason why high-speed medium-speed high-pressure Ore Milling Equipment consumption, March 16 & mdash; March 28 team members went deep into the production site, the grinding system (medium-speed high-pressure Ore Milling Equipment) anatomy, Analysis, find nine end factors, namely, serious stator wear, serious rotor wear, roll sleeve cycle unreasonable, small hardness sleeve, liner thinning, the upper (lower) air ring wear serious (because of the high speed Ore Milling Equipment is grinding the stone into a fine powder, grinding process and stones and powder contact will inevitably wear parts, when the wear and tear to take appropriate measures).

To Confirm

Research team on the 9 end of the investigation, analysis, induction, demonstration:

End Of A Factor: Severe Stator Wear

In 2011, the splitter stator was repaired three times without replacement. Repair a total cost of 900 yuan three times, the stator machine consumption accounted for medium-speed high pressure Ore Milling Equipment power consumption ratio was 0.147%. Conclusion: non-essential reasons.

End Two Factors: Serious Rotor Wear

2011 separator rotor repair nine times, replaced three times. Rotor machine occupy medium-speed high-pressure Ore Milling Equipment consumption was 1.27%. Conclusion: non-essential reasons.

End Three Factors: Turning Sleeve Cycle Unreasonable

 

Now operating "medium-speed high-pressure Ore Milling Equipment operating instructions" provides abrasive 5 kt after turning the second roll. 25,000 tons of abrasive roll cover for two sets. In 2011 a total of 5 sets of roll cover. Roller cover machine consumption accounted for medium-speed high pressure Ore Milling Equipment power consumption ratio was 53.10%. Conclusion: The reason.

End Four: Roller Hardness

The company installed medium-speed high-pressure Ore Milling Equipment has initially been based on the hardness of the material (pyrophyllite hardness 1 & deg; & 2; deg;), consult experts, experts recommend a higher hardness roller 62 & deg; & 63; Set of hardness 62.5 & deg ;. Conclusion: non-essential reasons.

End Five: Liner Thinning

Liner with the use of time increases, the liner thinner and thinner, the gap between the roller and the disc will be more and more, if the adjustment of the gap unchanged, it will reduce the roller bearing shaft and disc angle, increase the grinding Roller inclination. The lining of the better working condition is the thickness of 70mm & 75mm.

Countermeasure Implementation One

 

Roll sleeve cycle abrasive 5,000 tons is reasonable? Experiments were carried out on medium speed and high pressure pulverizers # 1, # 2 and # 4, respectively, and the cycle of medium speed and high pressure pulverizer # 1 was changed to 4,000 tons and the cycle of medium speed and high pressure pulverizer # 2 was changed to 3,000 tons , 4 # medium speed high pressure Ore Milling Equipment cycle to 2000 tons. Statistics May 1 #, 2 # and 4 # medium speed high pressure Ore Milling Equipment stick sleeve machine consumption were 2.26 yuan / ton, 1.88 yuan / tonne and 1.86 yuan / ton. Taking into account the abrasive roller 3000 times per second cycle more reasonable. Sub-goal machine roller consumption dropped to 1.9 yuan / ton in the realization.

Two Measures To Implement

The use of 5mm thickness of the steel plate, according to the size of the disc to make a mat, 3 # medium speed high pressure Ore Milling Equipment experiment, after two months of operation, in June the machine down to 0.96 yuan / ton, July 1 Medium-speed high-pressure Ore Milling Equipment operation in accordance with the countermeasures two, two measures at the same time implementation, operation for two months. August 1 statistical results are very unsatisfactory, medium-speed high-pressure Ore Milling Equipment roller sleeve machine consumption has risen, medium-speed high-pressure Ore Milling Equipment roller sleeve machine consumption was 2.05 yuan / ton; liner machine consumption was 0.99 yuan / Ton. For the two measures at the same time the implementation of high machine consumption. With the experiment that: Because the entire liner into the disc, it is not two planes, it is similar to the end of a large two pan. The two grinding rollers are ground on the plane part of the grinding disc and the edge root, while the upper edge of the lining plate can not be worn and will not be thinned. After the edge of the lining plate is lifted, the grinding roller has not dropped to a reasonable position and is the edge of the lining plate Has touched the sleeve. Determine to take the grinding roller along the support shaft direction liner center move 5mm solution to this problem.
