Carter Day Logo New

Carter Day has been manufacturing processing equipment for over 100 years and over those years they have obtained application information involving almost all cereal grains and other free flowing granular materials.

Carter Day’s equipment design strategy focuses on adaptability and trouble-free operation. Today’s models require dramatically lower maintenance than those of less than a decade ago. 

Indent Cylinder Separator- relies on 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 particles to ride up the rising side of the cylinder and fall into the trough.  To make adjustment on the "cut point" of the 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 amount of product which can be length separated depends on the number of pockets coming in contact with the product.

Precision Sizer - consists of four different styles of sizing cylinders with over 125 different size apertures.  As the product enters the cylinders, the rotating action presents the material in the most efficient manner to the close tolerance perforations to provide a precise separation.  Each cylinder has indexed cleaning wheels located at the top of the cylinder where near sized material is gently pushed back into the cylinder without damaging the grain.  This system is completely self-cleaning.

Disc Separator- consists of a series of discs mounted on a horizontal shaft.  The discs, each with hundreds of undercut pockets, revolve through the mass of material lifting the shorter material into a discharge trough at the front of the machine.  While the disc blades convey the longer rejected material to the discharge at the end of the machine.  This discharge has a retarder which controls the burden depth of product within the discs.
