Jan 07, 2015 · Water injection in to the mill The following examples show the effectiveness of spray water cooling in (open) and (close) circuit mill: Example-1: (open circuit) Cement temperature without spray (T1): 158 ºC Cement temperature with spray (T2): 103 ºC Cement flow rate (Fc) :14923 kg/h Specific heat of cement (Cpc): 0.20 kcal/kg

Feb 01, 2016 · Ensure that the plant air shut-off valves are open to the mill clutch and ring gear lube system. Also check the air pressure on the mill clutch air receiver tanks. This reading should be no lower than 90 psi (620 kPa). Check the ball mill discharge chute and cyclone overflow and underflow launders for obstructions and debris

Jul 31, 2014 · Wm = Wi ( 80P 10 - 80F 10 ) (1) where: Wm - is mill specific motor output power (kWh/t), Wi - is the Bond ball mill work index (kWh/t), P80 - is sieve size passing 80% of the mill product (µm), F80 - is sieve size passing 80% of the mill feed (µm), The “efficiency factors” (Rowland, 1975) modify equation 1 so that it caters for circuit conditions which are different from that Bond used to develop his original …

energy efficient cement ball mill from flsmidth

The more control you have over the mill, the better your grinding efficiency is likely to be. Our ball mills include monitoring systems to continuously measure the material and air temperatures as well as the pressure at the mill exit. The venting of the mill is adjusted by a damper in the inlet to the mill fan

Quantity of Air = 7.6 m3/sec Table 3.2 Chute design parameters Velocity of Air = 20 m/s [standard for cement ball mill] Flow rate Q = A x V A = Q / V = 7.6 / 20 = 0.380 m2 A = 3, 80,000 mm2 Actual area as per the existing chute is 371700mm2

Sep 15, 2017 · The air slide is a metal box divided into 2 parts: The upper part where the fluidized powder material is located The lower part where the air is at a pressure between 250 and 500 mmH2O A porous fabric membrane is located between the two parts of the housing

coal grinding - cement plant optimization

Cold air leakage percentage can be determined by measuring oxygen percentage at inlet and outlet of the circuit element. Coal Mill: Most commonly used mills for coal grinding in cement plants are closed circuit air swept (Single chamber) ball mills and vertical mills. Ball Mill:

Dec 02, 2019 · The finish mill system in cement manufacturing is the second to last major stage in the process, where the feed material is reduced in size from as large as several centimeters in …

The Airlift™ is a pneumatic conveying system designed for vertical transport of these kinds of dusty, dry bulk materilas materials. With hundreds of applications worldwide in cement, lime, gypsum, power and aluminium plants, among others, the Airlift™ is a proven low-maintenance solution with zero dust when connected to a dust collection system

pneumatic conveying | moving dry bulk materials

Our Airslide® air-gravity conveying system uses the forces of gravity to do most of the work with no moving parts. Material is fluidised through a porous media with low-pressure air, and flow is achieved by sloping the Airslide conveyor to match the fluidised angle of repose of the powdered material

With dry grinding, these mills often work in a closed cycle. A scheme of the conical ball mill supplied with an air separator is shown in Fig. 2.13. Air is fed to the mill by means of a fan. Carried off by air currents, the product arrives at the air separator, from which the coarse particles are returned by gravity via a tube into the mill

Jun 22, 2010 · Are you sure where the TIN comes from - do you have a side drive mill with girth gear ie oil circuit is for mill slide brgs and side drive gearbox. I am not sure of our TIN content in our oil - have not checked - but I think that you have issues to follow up. Is the mill support foundation OK - did you have a as built survey levels
