The SYNCRO-FLEX conveyor from General Kinematics consists of a trough in which material is carried, a base for mounting the conveyor and its machinery, rubber shear mounts which support the trough in position and serve as a spring reactor system, plus an eccentric drive which imparts a controlled motion to the trough.

Material moves ahead in the conveyor in a series of gentle "throws and catches" as a result of the controlled linear motion which is produced by the eccentric drive and stabilized by the rubber shear mounts.

The rubber shear mount spring reactor system is designed so that its resonant frequency matches the eccentric drive speed. This is a tuned or synchronized frequency system where all of the forces required to decelerate and accelerate the trough are balanced by the forces developed in the deflection of the shear mounts.

The eccentric drive provides only the additional energy lost because of friction. Since each shear mount functions as an individual drive, all forces are uniformly distributed along the unit and no large destructive stresses appear at the drive connections. Power requirements are kept to a minimum.

SYNCRO-FLEX Conveyors move materials at various
travel speeds depending upon the stroke and frequency
of the conveyor, as well as material characteristics such
as moisture content, density, interparticle slippage, etc.
Most materials, such as sand, crushed rock, and other
granular materials, will convey in the range of 40 to 60
F.P.M. Fine mesh materials such as dry cement or dust
have interparticle slippage and aeration qualities and
usually convey in the range of 10 to 40 F.P.M. Generally
the fine mesh materials will convey in a shallow bed,
therefore an oversize conveyor is recommended for
this type of material.

In some applications, when handling castings,
weldments or a friable material, it may be desirable to
size the conveyor using a slower conveying speed.
This will reduce the material impact on the trough
and the contact noise between pan and large pieces.
It will also minimize degradation and possible material
damage.

The trough width in some instances should be
determined by the dimension of the largest piece or
lump to be handled. Consult General Kinematics
for recommendations on hard to handle materials.
