Jun 19, 2015 We can calculate the steel charge volume of a ball or rod mill and express it as the % of the volume within the liners that is filled with grinding media. While the mill is stopped, the charge volume can be gotten by measuring the diameter inside the liners and the distance from the top of the charge to the top of the mill.
The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6. Rod mills accept feed up to about 50 mm (2 in.) and produce a product in the size range of 3000 to 270 mm (–4 to –35 mesh).
In, under different ball charge filling ratios, ball sizes, and residence time, a continuous ball mill is studied for optimizing cement raw material grinding process. In [ 5 ], an adaptive control framework is presented for raw material blending process, and corresponding optimal control structure is discussed too.

Labor Cost Calculator. Determine the impact of labor on total production costs and part costs. Labor costs are affected by the production time, labor rate, number of workers, and labor usage. Using these parameters, the total labor cost for production will be calculated, as well as the cost that can be attributed to each part.
The pores inside cement paste contain water (or pore solution), which can be classified into: Capillary water: Present in voids larger than 50 A o . Further classified into: (a) free water, the removal of which does not cause any shrinkage strains, and (b) water held by capillary tension in small pores, which causes shrinkage strains on drying.
The optimum speed varies as a percentage of the critical speed depending on the viscosity of the material being ground. For the dry powders used in pyrotechnics, the optimum speed will be 65% of the critical speed. Using the interactive calculator on this page will help you determine the optimal speed for your mill without having to reach
While the mill is stopped, the charge volume can be gotten by measuring the diameter inside the liners and the distance from the top of the charge to the top of the mill. The % loading or change volume can then be read off the graph below or approximated from the equation and calculation: % Steel Charge Loading in Mill = 113 – 126 H/ D
When the added complexity of on and off peak power costs, interruption clauses, supply charges versus energy charges, etc, are added, the evaluation of the benefits of energy saving investment can become very complex. Typical cement plant power costs can range from EUR39 to EUR170/MWh. Mill designs
Lets calculate/select/pick a new ball for your SAG mill. Now, lets suppose you have a SAG Mill and Ball Mill that are not drawing full kW Power. The SAG Mill has a "small" circulation load of oversize given be the 3/8″ trommel screen and the 1/2″ x 1 1/4″ discharge grates. The load of 4″ balls in this SAG is "good" but un-measured.
For grate discharge mills, the charge should occupy about 50% of the mill volume . Bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge, He, and the radius of the mill, R, i.e., Charge% = 113-(63H C /R)
The same policy is employed for the make-up charge where adding different ball sizes is done in order to optimize the mill performance. Chimwani et al. (2015) developed a simulation program that could predict optimal make-up balls to be added in order to achieve a required product fineness.

results metrics that can be used as key performance indicators for the maintenance function. Physical Asset Management The purpose of most equipment in manufacturing is to support the production of product destined to downstream customers. Ultimately the focus is on meeting customer needs. This is illustrated in Figure 1.
Optimum ratio between length L and diameter D, L:D is, usually, accepted in the range 1.56–1.64. The mill productivity also depends on many other factors: physical-chemical properties of feed material, filling of the mill by balls and their sizes, armor surface shape, speed of rotation, milling fineness and timely moving off of ground product.
The starting point for ball mill media and solids charging generally starts as follows: 50% media charge. Assuming 26% void space between spherical balls (non-spherical, irregularly shaped and mixed-size media will increase or decrease the free space) 50% x 26% = 13% free space. Add to this another 10%-15% above the ball charge for total of 23% ...

When properly sized, bypass during cold start can be avoided/minimized and optimum element efficiency and life achieved. The filter assembly differential pressure values provided for sizing differ for each media code, and assume 32 cSt (150 SUS) viscosity and 0.86 fluid specific gravity.
The dead load on a floor is determined by the materials used in the floor's construction. A typical wood-frame floor covered with carpet or vinyl flooring has a dead load of about 8 pounds per square foot; if there's wall-board covered ceiling suspended from the underside of that floor, the dead load increases to about 10 pounds per square foot.
