Low Profile Crushers
Low Profile Crushers have 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.
A low profile apparatus for scalping and crushing products comprising first and second cylindrical roll crushers journaled so that the rotational axes of said first and second cylindrical rolls are parallel and having a first and second radius, respectively; an input conveyor and an output conveyor each having a products side and a return side; means for journaling said first cylindrical roll so that the distance from the axis of said first cylindrical roll to the products side of said output conveyor is slightly greater than the radius of said first cylindrical roll; means for mounting said input conveyor over said first cylindrical roll so that the distance between the axis of said first cylindrical roll and the return side of said input conveyor is slightly greater than the radius of said first cylindrical roll; means for journaling said second cylindrical roll above said first cylindrical roll so that the maximum height of said second cylindrical roll is at least equal to the height of the products side of said input conveyor and less than the maximum height of any products on said products side of said conveyor; means for mounting the input end of said input conveyor in substantially the same plane as said output conveyor; means for mounting said output conveyor under said input conveyor; and scalping means for passing product of a predetermined maximum size or smaller from said input conveyor to said output conveyor said input conveyor conveying product above said predetermined size to said first and second roll crushers wherein it is sized and passed to said output conveyor.
