Today, the cost of raw material is rising, and the energy-saving equipment is the first choice for production enterprises, and the energy-saving consumption consumption reduction can provide a solution to produce production costs. (The article is collected by the ball mill manufacturer, the content of the article is for reference only)
In the market competition, it is more intensified today, and every reduction of a penny production cost, it means more market competitive advantage, energy saving and reduced consumption of 900,000 yuan / year It is still self-satisfied. In terms of investment, it is about 2 million yuan for the establishment of a tonal mill, and the investment cost can be recovered in two years, and its economic benefits are very significant. Under the comparative premise, the use of a free iron mill can save 844800 degrees / year, which is 129.6 tons / year. Many economically developed, energetic countries, such as: Italy, Spain, Turkey, Iran, Yemen, India and other countries use a linear ball mill to reduce energy consumption and production costs. These countries have more energy-saving and consumption consumption than my country. As a high-energy, high-input domestic manufacturers should be converted to investment and management thinking and ways?
Selection of iron mill uses computer centralized management, the entire raw material preparation workshop only requires an operator, calculated according to 1000 yuan / month, and the part of the salary is: 3000 yuan / month, 30,000 yuan / year. Three operators using a batch ball mill throughout the workshop, calculated according to 1000 yuan / month, three classes, this part of the salary is: 9000 yuan / month, 90000 yuan / year. Using a free iron mill than the intermittent ball mill saving workers: 90000 yuan -30000 yuan \u003d 60000 yuan / year, one ∮2.2 × 14 m-choice iron ball grinder annual maintenance cost is equivalent to 2 intermittent ball mills, The annual maintenance cost is also comparable to the output of 1: 6. In summary, the use of a free iron mill than the batch ball mill for 1 year (10 months), the annual electricity fee is 509414.4 yuan, saving the land of 213.5m2, the annual reduction of energy cost 324,000 yuan or more dry powder 1440 tons, maintenance costs are ignored, the annual provincial labor salary is 60,000 yuan, and the total energy saving is reduced to 893414.4.
In the case of stability of raw materials and complies with process requirements, the output of 1 ∮2.2 × 14 m is equivalent to the total output of 4 30-ton intermittent ball mill, but the color power of iron mill is selected. Performance and the control of raw material processing are significantly higher than the intermittent ball mill. That is to say, the use of the free energy conservation consumption consumption consumption is more remarkable, the ingredients are more advanced, more scientific, and make the quality of the ceramic products more stable.
First power saving: The power consumption of the tin ball mill is: the main motor 200kw × 2 \u003d 400 kW / hour. The total power consumption of the free iron mill is: 400kW × 22 hours \u003d 8800kW / day, the power consumption of the 30-ton intermittent ball mill is: the main motor 132kw / 1, using a 30-ton intermittent ball millThe total power consumption is: 132kw × 4 sets × 22 hours \u003d 11616kw / day, using the selection of iron mill daily power saves: 11616kW-8800KW \u003d 2816kW / day, according to the average electricity electricity 0.603 yuan / degree calculation daily The power saving cost is 2816KW × 0.603 yuan / degree \u003d 1698.048 yuan / day, starting 300 days, 300 days, 1 year of power saving cost is 1698.048 × 300 days \u003d 509414.4 yuan
Second High efficiency: The mud moisture content of the slurry is 30-32%, and the ball grinding mud can enter the spray column granulation directly in the mud pool, and the mud temperature of the spray column still has 70 ° C to 80 ° C. . The mud moisture content of the batch ball mill is 34-36%, and the slurry temperature of the slurry tank is about 30 ° C when the slurry is aggravated into the spray column. In other words, it is the slurry water content that is the mud moisture of the iron ball mill than the mud moisture ratio that is grinded from the batch ball mill is 4% lower, and the mud temperature is 40-50 ° C. It is not difficult to understand the advancement of the iron ball mill by high and low comparison of energy saving efficiency. The energy consumption of the spray tower evaporates per kilogram of water is: 900-950 kcal. Take a 5000-type spray tower as an example: the amount of water evaporation per hour is 5,000 kilograms. It can increase the production of 5000 × 4% \u003d 200 kg / hour, which can be produced by 200 × 24 \u003d 4800 kg per day. . The same output can reduce energy consumption of 200 × 900 kcal / kg \u003d 18,000 kcal / hour, with fuel calculation of 10,000 kg / kg, saving 18 kg of diesel every hour, saving 432 kg of diesel every day. A fuel fee per day with a 180 # heavy oil in 2500 yuan / ton: 432 × 2500 yuan / ton \u003d 1080 yuan. Fuel fee per year: 1080 yuan × 300 days \u003d 324,000 yuan.
The third floor is small: a selection of iron mill covers an area of \u200b\u200bapproximately 7m × 17m \u003d 119m2, five intermittent ball mill: ball mill part: 7m × 9.5m × 5 sets \u003d 332.5m2 in comparison In the case, it is effective to reduce the area of \u200b\u200b213.5 m2.
