Tube Capacity Chart - Rogue Fabrication

We offer 2 hydraulics systems for our machine. The air/hydraulic system covers the entire chart above. The electric/hydraulic system can be configured with a 5 ton or 9 ton cylinder, and the 5 ton maxes out at 1.5 x .156 wall square tube or 1.75 x .156 round tube, or 2.00 x .120 round tube. This is because the power of the electric/hydraulic ...

Roll Crusher - an overview | ScienceDirect Topics

The capacity of the single-roll crushers is a function of the roll gap, the roll length, and the speed, and ranges from about 30 tons/h (27 metric tons/h) for a 24-inch-long (61 cm) roll crushing to ¾ inch (2 cm), up to approximately 1500 tons/h (1360 metric tons/h) for an 84-inch-long (213 cm) roll crushing to pass 10 inches (25 cm).

Roll crushers - SlideShare

ROLL CRUSHER Roll crushers are used 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. 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 ...

Roll Crushers - ScienceDirect

A smooth surfaced roll crusher had a roll diameter of 910 mm. Its suitability to crush an ore at 10.0 t/h was being examined. Preliminary examination showed that the kinetic friction factor was 0.36 when the speed of revolution was 33 rpm. The average diameter of particles fed to the crusher was 200 mm and the S.G. of the ore was 2.8. Estimate: 1.

Sugar - Milling Tandem Capacity

There are a large number of formulae for the calculation of the capacity of a milling tandem. Hugot gives the following formula: A = 0.9 c·n·√N· (1-0.06·n·D)·L·D 2 /f. where. c. is a factor dependent on the cane preparation equipment, c. = 1.3 if the tandem is preceded by a shredder. n.

Crusher Efficiency Calculations

A twin-roll crusher is selected, like those given in the Roll Crusher capacity Table above, to serve as the reduction crusher. The smallest, 24 x 16 roll crusher shown in the Roll Crusher capacity Table above has enough capacity with a setting of 1 in. but the maximum size feed will be too large, that is, the stage of reduction is not large enough.
