Automatic Double Roll Crusher
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. Toothed roller crusher 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

Osborn double roll crushers increasingly chosen for SA coal mines
“The feed material should enter the centre of the gap between the two rolls and spread across the full roll width for maximum efficiency, and this ensures a uniform product size distribution. For strict coal product specifications, the Osborn Double Roll Crusher is ideal.

The gape determines the maximum size of material that can be accepted. Maximum size that can be accepted into the crusher is approximately 80% of the gape. Jaw crushers are operated to produce a size reduction ratio between 4:1 and 9:1. Gyratory crushers can produce size reduction ratios over a somewhat larger range of 3:1 to 10:1.

Fig. 11 shows the predicted product size distribution for the cone crusher. The minimum resolved size of material in the simulation is 8 mm. By using empirical progeny distributions, the model is also able to predict the finer material produced by the crusher below this resolved size down to a minimum of 0.66 mm.

How Do Roll Crushers Work? | Crushing And Screening Blog
Some roll crushers have a feature that enlarges the feeding port in such cases, so those materials can be immediately discharged from the roll crusher before any damage occurs. The greatest advantages of the roll crushers are the fine product size distribution and the very little dust it produces.

Size Reduction of Bulk Materials
Roll Crusher. Single roll crushers use a drum rotor to crush friable materials against a breaker plate. Double roll crushers use compression to reduce particles between the gap of two crushing rolls. Both the single roll and double roll crushers have adjustments to allow for varying particle size outputs.

MATHEMATICAL MODELS OF PARTICLE SIZE DISTRIBUTION IN
A theoretical approach to determination of particle size distribution of crushing products was presented by Kolmogorow (1941) and Epstein (1947), who proved that for a multi-stage comminution process, the particle size distributions of products are log-normal. The product particle size distribution depends on the crushing process intensity (stage).
