A motor with around 1400 Horse Power is calculated needed for the designed task. Now we much select a Ball Mill that will draw this power. The ball mill motor power requirement calculated above as 1400 HP is the power that must be applied at the mill drive in
Maintaining mill power up to 1700 kw by ball charging forged steel balls replaced with hichrome balls for consistency in mill power this has been done in seven mills and another three mills shall be converted in 201314 whenever any raw coal feeder of a mill with blended coal feeding. Chat. Online 24 Hour.
08.05.2017· 1 1.01/1 0.4 = 1.5. Thus, the power to drive a rod mill, without a powder charge, will be given approximately by. PR = 1.5PB .. (3.24) where PR is the power to drive the rod mill and PB is the power to drive the corresponding ball mill, as calculated from the foregoing formulae.
between the ball-mill power draw values determined from the Denver slide rule, and those calculated from the proposed model. zFrom the distribution of the points around the line of comparison the good agreement of the results received is obvious. 0 200 400 600 Ball mill power draw predicted from the Denver slide rule, kW 0 200 400 600

Ball mill power draw predicted from the Denver slide rule, kW 0 200 400 600 Calculated ball-mill power draw from the m odel derived, kW Data compared Line y=x Fig. 2. Comparison of the ball mill power draw from the Denver slide rule and the proposed model. Dashed line corresponds to y=x. 19 COMPARISON BETWEEN THE BOND (CLASSIC) AND THE PROPOSED METHODS 4 D = 5.49 m,
W is the work index measured in a laboratory ball mill (kilowatt-hours per metric or short ton) P 80 is the mill circuit product size in micrometers; F 80 is the mill circuit feed size in micrometers. Rod mill. A rotating drum causes friction and attrition between steel rods and ore particles.  But note that the term 'rod mill' is also used as a synonym for a slitting mill
Table Energy saving effect of the vertical roller mill Ball mill Specific power Cost estimation About 14million US$ [Newly-built] and about 230 million US$ [retrofitted], including the cost of supplemental facilities [200t-RM/h] [1US$=¥110] Related matters References Fig.1 Vertical roller mill Vertical roller mill Effect(%) Production ％ 100 160～180 60～80(increase) consumption kWh/t-RM
A 10 MW cement mill, output 270 tonnes per hour. A cement mill (or finish mill in North American usage) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement. Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills. History. Early hydraulic cements, such as those of
If you need a ball mill, let me know. Phone and WhatsApp: +86-13838585676 Email: [email protected] By the way, we are a manufacturer from China.
Industrial air compressors produce approximately 4.5 SCFM per horse power (hp). Blasting cabinets require 3 to15 hp compressors per nozzle and blast rooms can use up to 53 h.p. per man or nozzle. BLASTING TECHNICAL INFORMATION . THERE ARE TWO TYPES OF AIR BLAST DELIVERY SYSTEMS Suction ( used in blast cabinets) Pressure ( used in blast cabinets, blast rooms, and outdoor blasting
The power consumption of a 42-inch gyratory crusher is approximately 2.4 tons per horsepower-hour (2.9 t/kWh). Source: Arthur Taggart Source: Arthur Taggart Power consumption of a jaw crusher when idling is about 50% of full load, for a gyratory it is approximately 30%.
Where T = tons of ore per hour. and Q = tons of added water per hour or T = tons of ore (for batch determinations) and Q = tons of added water. In both cases Dx and D2 are dilutions (tons of water per ton of ore) before and after addition of water. These are found from the specific gravities of the pulp, by formulas (4) and (6) or directly by the use of the tabulation on these of Pulp Density
Hours of use per day: h/day: 1 kilowatt-hour (kWh) cost: Electricity cost per day: Electricity cost per month: Electricity cost per year: Electricity bill calculation Energy consumption calculation. The energy E in kilowatt-hours (kWh) per day is equal to the power P in watts (W) times number of usage hours per day t divided by 1000 watts per kilowatt: E (kWh/day) = P (W) × t (h/day) / 1000
