The theoretical capacity of crushing rolls is arrived at simply by calculating the volume of the ribbon whose cross section is the area of the discharge opening, and whose length is the peripheral speed of the roll faces per unit of time. The formula, for material weighing 100 lb per ft3, is D x W x S 48 = TPH.
Mar 06, 2013 The hopper areas on single roll crushers are of a large, unrestricted design spanning the full width of the crusher roll. This construction allows the machine to crush large feed lumps delivered into the hopper. The hopper is flanged at the top and equipped with drilled bolt holes for attachment of an auxiliary hopper or feed chute above the.
Double Roll Crushers. Double Roll Crushers typically follow a primary or secondary crusher and are used for secondary and tertiary reduction of various minerals, such as ROM coal, clean coal, limestone, gypsum, trona, shale, bauxite, oil shale, coke, salt, lime, glass, kaolin, brick, shale and wet, sticky feeds.
Jul 30, 2012 Since there is no provision for the swelling of broken ore in the crushing chamber, roll crushers must be “starvation fed” if they are to be prevented from choking. Although the floating roll should only yield to an uncrushable body, choked crushing causes so much pressure that the springs are continually “on the work” during crushing, and some oversize escapes.
