ABSTRACT:
An apparatus and method for feeding polymeric material to processing and mixing equipment is disclosed which includes a hopper located radially from the axis of rotation of the processing equipment in the direction of rotation and with walls that are inclined at angles which direct the feed material toward the direction of rotation. In addition, a passage is provided within the apparatus for venting gases. The rate of egress of feed material from the hopper to the processing equipment is controlled in response to the need of the processing equipment.
The disclosed apparatus includes a casing, a hopper inclined in the direction of rotation of the processing equipment, a control means acting as a gate for the introduction of new material and forming a passage in conjunction with the casing to provide a space for the escape and removal of volatile material from the processing equipment.
The control means may be moved about a pivot in such a manner as to encourage the feed material into the processing equipment. Such motion may be controlled by an automatic system that responds to the need of the processing equipment for additional feed material.
