When crushing tough materials, you need a rolls crusher that gets the job done efficiently. Essa® Rolls Crushers – plain or toothed rolls.
Roll crushers are arbitrarily divided into light and heavy duty crushers. The diameters of the light duty crushers vary between 228 and 760 mm with face lengths between 250 and 460 mm. The spring pressure for light duty rolls varies between 1.1 and 5.6 kg/m. The heavy duty crusher diameters range between 900 and 1000 mm with face …
A roll crusher capacity is a measure of the amount of weight per unit time that moves through a roll crusher during operation. The theoretical maximum capacity is calculated by the equation above, but typically there are a few inefficiencies in the system that cause the true number to be 10-30% less.
Roskamp Roll Crushers are designed for the most demanding crushing applications, with roll corrugations and roll speed differential ratios available to match any operating conditions. Available in two-, four- and six-roll designs, the 1200 Series has a 12" roll diameter and a range of 30 to 225 HP.
A double roll crusher consists of two rolls. Crushing takes place between two cylindrical rolls with each rotating about a concentric horizontal shaft in opposite directions. This is the most common of all roll crushers. Grinding machines are used for reducing crushed particles into their smallest functional sizes.
