Length Grader - Variable Speed Indented Cylinder Separator , Adjustable Trough Tilt For Optimal Particle Separation

Length Grader

Principles of Operation
The indented cylinder separator relies upon centrifugal force; the speed of the cylinder holds the particle in the indent. lifting it out of the mass until the indent is inverted to the point where gravity causes the particle to fall out of the indent. The particle dropping from the indent falls into the auger conveying trough. The angle or tilt of the catch trough must be adjusted to obtain the desired "cut point" there by catching the small particles as they drop out of the indents but not permitting the longer particle to ride up the rising side of the cylinder and fall into the trough. To make adjustment on the cut point of separation, a trough tilt adjustment is used which enables you to define the degree of separation that is required. A screw conveyor then discharges the short lifted material separate from the tailed long material. The quantity of material which can be separated based on length depends on the number of pockets coming into contact with the product.

The variable speed system consists of spring loaded V belt pulley on the motor. The rotation speed of the cylinder may be changed by the
external cylinder speed adjustment wheel which slides the motor base changing the input speed and in turn the speed of cylinder.

It may be used independently or arranged in stacks of 2 or 3 high in various flow arrangements to meet higher capacity requirements or provide multiple separations.
