MIXING BATCHER Russian patent published in 1995 - IPC

FIELD: formula feed industry. SUBSTANCE: mixing batcher comprises a cylindrical housing, spiral, replaceable insert, drive pulley and service hopper with a partition. Secured outside on the drive pulley hub is the spiral with the insert secured by one end to the housing and passing freely through said spiral. The cylindrical insert is installed under the first compartment of the service hopper so that the stationary insert reserves a part of space inside the spiral for batching the next component in correspondence with its volumetric relation in the mixture. The partition of the service hopper is fixed in the plane of the free end of the cylindrical insert so that the lower contour of the shaped recess in said partition coincides with the internal circumference of the spiral housing. EFFECT: improved design. 2 dwg
