Abstract. Crushing and pulverizing reduces the material to a uniform size, or to a graduation of sizes for immediate use or further processing. The various manufacturers make specialized crushers for various processes, such as reduction of long coils of metals into short lengths, reduction in size of run-of-mine coal down to one inch and under in one operation, and crushing of rock or ores ...
The bottom of the Pennsylvania Crusher reversible impactor is open and the sized material passes through almost instantaneously. Liberal clearance between hammers and the breaker blocks eliminates attrition and crushing is by impact only. Pennsylvania Crusher single roll crushers reduce large input by a combination of shear, impact and compression.
2. Design Analysis and Calculations 2.1 Roll Crusher Geometry It is necessary to estimate the maximum size of the mineral particles that can be fed into the machine for a known roll diameter, roll length and roll gap. It is convenient to assume that the particle is spherical and the roll surfaces are smooth when calculating for
analysis of the loading force distribution acting on the crusher's mantle and the torque in the mantle geometry is performed with a moving frame of reference in polar coordinates. With this variable change, a planar force and torque distribution can be obtained, as can be observed in a previous work [21] and machines such as jaw crushers [24].
