Calculating Mechanical Power Requirements Physically, power is defined as the rate of doing work. For linear motion, power is the product of force multiplied by the distance per unit time. In the case of rotational motion, the analogous calculation for power is the product of torque multiplied by the rotational distance per unit time. P rot = M w

the crusher consumes 40 kW of power of which 5 kW are required for running the mill empty. Calculate the power consumption if 12 tonnes/h of this product is further crushed to 5 x 10 (-4) m size in the same mill? Assume that Rittinger’slaw is applicable. ?It is desired to crush 10 ton/hr of iron ore hematite. The size of the feed is

Feb 25, 2015 Crushing efficiency has been defined in the literature from the power consumption point of view. But while operating a process plant, it is more important that the crushing efficiency is defined in terms of the requirement of subsequent process. The Process plant has been designed for coal size - 13 mm ( 80 % passing).

Jaw and gyratory crushers are used for initial size reduction to convert big rocks into small stones. This is generally followed by a cone crusher. A combination of rod mill and ball mills are then used if the ore must be ground below 325 mesh (45 μm). Instead of grinding the ore dry, slurry is used as feed for rod or ball mills, to avoid dusting.
2 inches. This is required to prevent blockage of the feeding and handling equipment prior to the mill. BTM's with crusher/ dryers can grind coals of almost any size without mill deration. Occasional lumps of 3-4 inches will not affect mill performance. In fact, the standard capacity of the mill increases 10% if a crusher/dryer is incorporated.

Crushers. Crushers are widely used as a primary stage to produce the particulate product finer than about 50–100 mm in size. They are classified as jaw, gyratory and cone crushers based on compression, cutter mill based on shear and hammer crusher based on impact.
Learn how a ball mill works, all of its main parts and some of its design features! This 3D animated video allows you to see all the internal parts of a ball
The Jaw Crusher BB 50 has been specially designed for sample preparation in the laboratory. It is used for the rapid, effective crushing and pre-crushing of medium-hard, hard, brittle and tough materials. The space-saving, dust-tight instrument fits on any laboratory bench and is ideally suited to crush small amounts of sample with large feed sizes gently and without loss.
Oct 19, 2015 Ball Mill Motor Power Draw Sizing and Design Formula. The following equation is used to determine the power that wet grinding overflow ball mills should draw. For mills larger than 3.3 meters (10 feet) diameter inside liners, the top size of the balls used affects the power drawn by the mill. This is called the ball size factor S.
circuit power requirements for autogenous and semiautogenous milling. The method is widely used by RIVS in extended calcula-tions at early design stages. The article is composed of sections successively informing on the existing techniques of sizing SAG mill power, Bond work in-dexes and their applicability to calculating autogenous/semiau-
3. Power draw of the comminution equipment (kW) ?In the case of mills, the power draw should be repre-sented in terms of power at pinion for gear and pin-ion drives and at shell for gearless drives. For crushers, this should be the net power draw, that is, the gross (motor input) power draw less the no-load power…
a e /d 1 Ratio of radial width of cut to cutting diameter: Calculated Required Power. F t Tangential cutting force: lb N. T Torque at the cutter: in.-lb Nm. Machining Power. P s at the cutter: HPc kW. P m at the motor: hp kW. These calculations are based upon theoretical values and are only intended for planning purposes. Actual results will vary.
Scale-up criterion is the net specific power consumption, i.e. the power consumed by the mill rotor itself minus all mechanical and electrical losses divided by the feed rate of solids. For the full scale mill, specific power is multiplied by the feed rate to get the net mill power.
Crushers are commonly classified by the degree to which they fragment not starting material with wares crushers not reducing it by much, intermediate cruiser fragmenting it much more significantly and grinders reducing it to a fine power. Impact crushers: they involve the use of impact rather than pressure to crush materials.
