Roll Crusher With stable Performance - Fote Machinery(FTM

Advantages of roll crusher High reduction rate and large capacity 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.

Pea Coal Vs. Chestnut Coal Vs. Stove Coal | Hand Fired

The differences after changing coal size might be large or small but it will be different. The velocity of the combustion gasses that allow for heat exchange to happen is altered and will effect the rate of heat output **. Explained another way, the pea vs larger issue can be compared to using a manual pipe damper (MPD).

Types of Rock Crushers | Quarry Crushing Equipment | Kemper

For instance, if the final size of your product only needs to be between 4 inches and 6 inches, a primary jaw or impact crusher can accomplish your goals. However, you will likely require a much finer product, and that means incorporating up to three—or even four—stations with a variety of crusher types.

Roll Crusher - an overview | ScienceDirect Topics

They are designed both to reduce the size of large coal lumps to less than 6-14 inches, and also to feed materials out of bins and onto conveyors or chutes. Conventional single-roll crushers use a simpler toothed-roll design, and are commonly used to reduce coal to approximately 2-3 inch (5-8 cm) topsize.
