There was a logical purpose behind this arrangement. Because of the variables involved, it would be the exception, rather than the rule, if both roll faces ran at exactly the same speed under no-load conditions, and if this “slip” between faces continued when the rolls were loaded, wear on the shell faces would be greatly accelerated. The large-and- small pulley set-up permits the material to “gear” the shell faces together so that the speeds are the same, and any compensation that might be required in surface speeds is taken care of by belt slippage on the small pulley.
The diagram in Figure 3 shows the method used in calculating maximum feed size for any diameter of rolls the accompanying table gives a listing of feed sizes for standard diameters. These figures are based upon zero roll spacing therefore the distance between faces (i.e., the discharge spacing to be used) should be added to them to obtain the maximum feed size for any combination of roll diameter and setting. The calculations are predicated on a coefficient of friction of 0.3, which is safe for most materials, provided that the surface speed of the rolls is not too high.

Manufacturer of roll crushers For crushing a variety of soft, brittle to toughly-hard products, Roll Crushers offer high throughput with narrow particle size distribution Available in four models The creation of undesirable fine particles is reduced by subjecting the.
The roll crushers are not as productive as cone crushers, with respect to volume, and they do have a little higher maintenance associated with them Roll crushers do, however, give a very close product size distribution, and if the ore is not too abrasive, they do not have high maintenance costs.
For grinding a variety of soft to medium-hard products, the Roll Crusher offers high throughput with narrow particle size distribution Compact, rugged and easy-to-use, the Roll Mill is especially suitable for cracking oilseeds, press cake and other soft to medium-hard materials in the manufacture of chemicals, pharmaceuticals, plastics and food products.
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) Some major advantages of roll crushers are they give a very fine product size distribution and they produce very little dust or.
By far the greater number of crusher applications involve feeds which are either graded (a mixture of large, medium, and small particles), or sized to a top dimension well within the effective receiving-opening dimension of the crusher. Primary crusher feeds usually fall under the “graded” category, and reduction crusher feeds under the “sized.” Graded feeds may or may not have the under-size removed, depending upon the nature of the operation and of the material. Sized feed for reduction crushers is generally a screened feed which has definite maximum and minimum limits.
If the ore feed to any gyratory or jaw crusher consisted entirely of large cubes or spheres of a size that would just barely enter the crushing chamber, the crusher could not be expected to produce anything like its normal rated capacity because the upper part of the crusher could not shatter the large pieces enough to keep the rest of the crushing chamber busy. Such a condition is of course.
Crusher segments last longer when the crushing is done efficiently, i.e. with the correct crushing ratio, roll speed and roll diameters are used. Direct saving in less frequent replacement costs and down time saving. Maximising Desirable Product Size Distribution.
Roll Crushers For crushing a variety of soft to medium-hard products, Bauermeister's Roll Crushers offer high throughput with narrow particle size distribution. The creation of undesirable fine particles is reduced by subjecting the product to a combined shearing and pressing action.
For mine operators, carrying out the primary crushing below ground and directly at the working face is generally an attractive solution which offers a number of advantages compared to open cast mining. For subsequent processing, the discharged material can be transported from the crusher by belt conveyor systems – an efficient and economical alternative compared to other extraction methods. The challenge for the applied crushing technology is primarily the limited space available in the underground tunnels and caverns, which results in.
