Thus the actual capacity, Q = .356 t/hr 2.1.9 Crushing Power The required crushing power is a

For example, a two-roll crusher with 24-inch-long (61 cm) rolls crushing to ¾ inch (2 cm) has a capacity of 75 tons/h (68 metric tons/h), which is approximately 2.5 times the capacity of a single-roll crusher with the same roll width and topsize setting.Roll crushers - SlideShare,24-04-2015· DOUBLE ROLL CRUSHER Working Principle and Structure of Double Roller Crusher 1.this series of roll crusher is mainly formed by the roller, roller support bearing, compression and adjusting device, drive components etc. 2.the adjustment of the particle size: between the two rollers equipped with adjustment device like pads or wedge.The wedge-shaped device has a adjusting boltDouble Roll & Teethed Roll Crusher,Although its brief period of popularity passed some thirty-odd years since, and only a few sets were installed before interest reverted to other types, the high-speed double roll crusher developed by Thomas A. Edison shortly before the end of the last century warrants a place in any discussion-of crushing equipment. In 1960, the largest machine of this type the 6 x 7 foot “giant” rolls,

Roll crushers have a theoretical MAXIMUM reduction ratio of 4:1. If a 2 inch particle is fed to the roll crusher the absolute smallest size one could expect from the crusher is 1/2 inch. Roll crushers will only crush material down to a minimum particle size of about 10 Mesh (2 mm).

A practical formula for the determination of the capa city of jaw crushers was developed by Taggart; it reads: Notation: Q Crusher capacity, t/h. b Width of jaw, centimeter. d Size of crushed material, centimeter. This formula generally complies with practical results achieved with medium size crushers. For large size,Crushing of coal and calculation of size reduction,25-02-2015· Roll Crusher • The reduction ratio and efficiency of roll crusher is very low. • The main advantage associated with roll crushers is small proportion of fines produced and more uniform size of product crushed, than the other crushers. • Low capacity • Low reduction ratio = F/P • Sensitive to top size 2/25/2015 6:58:05 AM 38 39.

Current screen capacity calculations do not take into consideration enough of the factors affecting screen efficiency. The old formulas were designed to keep calculations short and manageable for manual calculation. The common use of computers in today’s world makes it possible to do more complex screen capacity calculations in much shorter time.Crusher Efficiency Calculations,The following example demonstrates a method of selecting the components of an aggregate plant.

The formula used here helps you find the net capacity which is, in effect, your load-weight limit, and can be substantially lower than the truck's original rated capacity. If the load-weight limit is too restricting for your job, you will probably need a truck with a higher original capacity rating.Civil Engineering Practice - Dr.A.Shah - Home,ROLL CRUSHERS • Roll crushers areused for producing additional reductions in the sizes of stone after the output of a quarry has been subjected to one or more stages of prior crushing. • A roll crusher consists of a heavy cast-iron frame equipped with either one or more hard-steel rolls, each mounted on a separate horizontal shaft. 12MINERAL PROCESSING LABORATORY MANUAL,To study the jaw crusher and determination the actual capacity, reduction ratio and Verification of Rittinger’s law of Crushing. 13-15 6 Crushing of Ore in a roll crusher, and Determination of average size by sieving. 16-18 7 To determine the reduction ratio, theoretical capacity, and actual capacity of a roll crusher. 19-21 8
