subject: Continuous Ball Mill And Intermittent Ball Mill [print this page] Continuous ball mill and intermittent ball mill
There are many types of ball mill. It is not an easy task to organize a factory or a production line for people who had not any contact with such equipment, then, how to organize a new plant , first of all, this industry equipment have a preliminary understanding of them, the ball mill is mainly used in mineral processing and building materials industry, but the areas do not, for different purposes, different purposes and different specifications, so the mill so many years of development gradually diversify, so, the following continuous ball mill with intermittent ball mill, for example, the classification of the ball mill, and the difference between an initial classification.
In today's rising cost of raw materials, energy is severely strained, using energy-saving device is a ceramic enterprises preferred energy saving significant continuous ball mill can provide solutions for ceramic enterprises to reduce production costs.
In the quality and stability of raw materials and meet the technical requirements under the conditions of 1 2.2 x 14 meters of continuous mill production and the total output of 30 tons intermittent ball mill, but the continuous ball mill superior energy-saving performance and The degree of controllability of the processing of raw materials was significantly higher than the intermittent ball mill. That is continuous ball mill energy saving is more significant, more advanced ingredients the more scientific to make the quality of ceramic products more stable.
1, power:
The power consumption of the continuous ball mill: the main motor 200kw 2 = 400KW / hour.
The total power consumption of continuous ball mill every day: 400KW x 22 hours = 8800kw / day
The power consumption of 30 t batch ball mill: main motor 132kw / 1 units
The total power consumption of 30 tons intermittent ball mill: 132kw 4 22 hours = 11616kw / day
Continuous ball mill daily electricity savings: 11616kw-8800kw 2816kw / day
Average power consumption of 0.603 yuan / kWh to calculate the the daily energy saving costs for
2816kw 0.603 yuan / kWh = 1698.048 yuan / day
Years start 300 days per the 1 energy saving costs for
1698.048 x 300 days = 509,414.4 yuan
2, covering:
A continuous ball mill, covering about: 7m 17m = 119m2
5 intermittent ball mill:
Part of the mill: 7m 9.5m 5 units = 332.5m2
Effectively reduce the contrast covers an area of 213.5m2
3, high efficiency:
Continuous type ball mill grinding out the mud moisture content was 30-32%, milled out of the mud transition in a mud pool look directly into the spray tower granulation, slurry temperature is 70 -80 still into the spray tower. Intermittent ball mill grinding out of mud water content was 34-36%, the slurry when the slurry tank banal into the spray tower temperature about 30 . In other words, the water content of mud that is continuous ball mill grinding out mud moisture content than the intermittent ball mill grinding out low rate of 4%, and make full use of the slurry temperature difference between 40-50 C. Level of energy efficiency is not difficult to understand the advanced nature of the continuous type ball mill.
Evaporation of the spray tower energy consumption per kilogram of water 900 - 950 kcal.
Example: a 5000-type spray tower per hour water evaporation capacity of 5000 kg, continuous ball mill can increase the yield of 5000 4% = 200 kg / h of dry powder per day prolific 200 24 = 4800 kilograms of dry powder. The same production can reduce the energy consumption of 200 900 kcal / kg = 18 000 kcal / h, calculate the heating value of 10,000 kcal / kg of fuel per hour can save 18 kg of diesel oil every day to save 432 kg of diesel oil.
2500 yuan / ton, 180 # heavy oil per day to save fuel costs: 432 2500 yuan / ton = 1080
Annual savings of fuel costs: 1080 300 days = 324,000 yuan
4, saving labor costs:
Continuous type ball mill using the computer to centrally manage the entire raw material preparation workshop only needs an operation of the workers, by 1000 yuan / month, three-shift system, the part of the wages: 3000 yuan / month, 30,000 yuan / year.Intermittent ball mill throughout the workshop requires a minimum of three operating workers, according to 1000 yuan / month, three-shift system, the part of the wages: 9000 yuan / month, 90,000 yuan / year.
Continuous ball mill than intermittent ball mill to save workers' wages:
90000 -30 000 yuan = 60,000 yuan / year
1 2.2 x 14 meters and the ball mill maintenance costs are approximately equivalent to the cost of two intermittent ball mill, the output ratio of 1:6, the maintenance costs are also relatively cost-effective.
In summary using the continuous ball mill cost savings than the intermittent ball mill for one year (10 months):
Save electricity 509,414.4
Save an area of 213.5m2
Reduce energy costs 324 000 yuan or prolific powder 1440 tons
Maintenance costs negligible
Save labor wages 60,000 yuan
Total energy saving 893,414.4
Intensified competition in the market today, reducing penny production costs, it means a little more competitive market advantage, energy saving, saving $ 900,000 / year, which means self-evident. Investment, the construction of a continuous ball mill is about 200 million two years to recover the investment costs, its economic benefit is very significant.Can be compared under the premise of continuous ball mill can save the country 129.6 tons / year of electricity of 844,800 kWh / year save oil. Many economically developed, the energy-abundant countries, such as: Italy, Spain, Turkey, Iran, Yemen, India and other countries have adopted a continuous ball mill to reduce energy consumption and production costs.
