Abstract
In a low profile crusher which has first and second cylindrical rolls journaled so that the rotational axis of the rolls are parallel and an input conveyor and an output conveyor is improved by journaling the first roll so that the distance from the axis of the first roll to the product side of the output conveyor is slightly greater than the radius of the first roll. The input conveyor is mounted over the first roll so that the distance between the axis of the first roll and the return side of the input conveyor is slightly greater than the radius of the first roll. The second roll is journaled above the first roll so that the maximum height of the second roll is at least equal to the height of the product side of the input conveyor and close enough to the first roll to produce a predetermined maximum size of product. A scalping method for the above is formed by mounting the input end of the input conveyor in substantially the same plane as the output conveyor. The mounting for the input of the output conveyor is under the input conveyor and a grating is mounted under the input conveyor so that at least a portion of the product of a predetermined maximum size or smaller on the input conveyor falls to the output conveyor and does not pass to the crusher.
