Comparison of Iron ball mills and intermittent ball mill energy saving reductions

　　Today, the cost of raw materials is rising, and today's energy-saving equipment is the first choice of production enterprises, and the energy-saving consumption consumption is significantly selected to reduce production costs for production companies. (The article is collected by the ball mill manufacturer, the article is for reference only) In today's market competition is more intense, every reduction of a penny production cost, it means more than one market competitive advantage, energy saving is 900,000 yuan / year, Do not speak clearly. In terms of investment, it is about 2 million yuan to build a tin ball mill, and the investment cost can be recovered in two years, and its economic benefits are very significant. Under the comparative premise, it can be used for the national saving of 844,800 degrees / year. It is 129.6 tons / year. Many economically developed, energetic countries, such as: Italy, Spain, Turkey, Iran, Yemen, India and other countries, all use Iron mill to reduce energy consumption and production costs. These countries have more energy-saving and consumption reduction in energy than my country. As a domestic manufacturer, high-input domestic manufacturers should be converted to investment and management thinking and ways? Choosing the iron mill uses computer centralized management, only one operating worker is required in the entire raw material preparation workshop, calculated by 1000 yuan / month, and the part of the salary is: 3000 yuan / month, 30,000 yuan / year. 3 operators using a batch ball mill, calculated, 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' wages: 90000 yuan -30000 yuan = 60000 yuan / year, one ∮2.2 × 14 meters selected iron ball grinder's annual maintenance cost is equivalent to 2 intermittent ball mills, The annual maintenance costs are also comparable to the output of 1: 6. In summary, the use of a free iron mill than the batch ball mill is saved (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 consumption is 893414.4. Under the conditions of stability of raw materials and compliance with process requirements, the output of 1 ∮2.2 × 14 meters is equivalent to the total output of 4 30 tons of intermittent ball mill, but the excellent festival is selected.Electricity and the controlled degree of raw material processing are significantly higher than the intermittent ball mill. That is to say, it is more remarkable with the energy saving consumption consumption of Iron ball mills, more advanced, more scientific, and makes the quality of ceramic products more stable. The first power saving: the power consumption of the tonal mill is: the main motor 200kw × 2 = 400 kW / hour. Use the total electric power consumption of the free iron mill: 400kW × 22 hours = 8800kW / day, the power consumption of the 30-ton intermittent ball mill is: the main motor 132KW / 1, the total power consumption of the 30-ton batch ball mill For: 132kw × 4 sets × 22 hours = 11616kw / day, using the selection of iron mills per day: 11616kW-8800KW = 2816kw / day, according to the average electricity electricity cost, the daily power saving fee is 2816kw × 0.603 yuan / degree = 1698.048 yuan / day, 300 days of starting 300 days, 1 year of power saving cost is 1698.048 × 300 days = 509414.4 yuan second efficiency: select iron mill grinding The mud moisture content of the slurry is 30-32%, and the ball grinding slurry can directly enter the spray column granulation in the mud pool, and the mud temperature in 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 is about 30 ° C after the slurry pool is stunned into the spray column. In other words, it is to select the mud water content of the iron ball mill than the mud moisture content of the mud moisture from the intermittent ball mill, and the penetration temperature is 40-50 ° C. It is not difficult to understand the advancement of the iron ball mill through the high and low comparison of its energy saving efficiency. The energy consumption of the spray tower evaporates the water per kilogram: 900-950 kcal. Take a 5000-type spray tower: the amount of water evaporation per hour is 5,000 kilograms. It can increase the production of 5000 × 4% = 200 kg / hour, which can be produced in 200 × 24 = 4800 kg dry powder per day. . The same output can reduce energy consumption of 200 × 900 kcal / kg = 18000 kcal / hour, with fuel calculation of 10,000 kcal / kg, saving 18 kg of diesel every hour, saving 432 kg of diesel every day. Calculated with 180 # heavy oil at 2500 yuan / ton, saving fuel costs per day: 432 × 2500 yuan / ton = 1080 yuan. Fuel fee per year: 1080 yuan × 300 days = 324,000 yuan. The third floor is small: a selection of iron mill covers an area of ​​approximately 7m × 17m = 119m2, five intermittent ball mill: ball mill part: 7m × 9.5m × 5 sets = 332.5m2 In comparative case, Effective reduction of floor area 213.5m2.
