A blender has a mixing chamber for reception of materials to be blended. A mixing screw is mounted at a bottom of the mixing chamber for mixing materials within the mixing chamber and delivering mixed materials to an outlet feeding a processing line. The blender has a plurality of material handling compartments. One or more cleaning air jets are provided in each material handling compartment. The cleaning air jets are operable to direct material towards an outlet of the compartment. Each cleaning air jet is connected to a pressurised air supply through a valve which controls delivery of pressurised air to the cleaning air jet.

A blender (1) has a frame (2). A number of raw material storage bins (3) are mounted at a top of the frame (2). Suspended on the frame (2) beneath the raw material storage bins (3) is a weigh hopper (4). Mounted beneath the weigh hopper (4) on the frame (2) is a mixing chamber (5) for reception of materials to be blended from the weigh hopper (4). A mixer, in this case provided by a mixing screw (6), is provided at a bottom of the mixing chamber (50) for blending materials within the mixing chamber prior to discharge of blended materials through a material outlet (7) at a bottom of the mixing chamber (5). The material outlet (7) discharges blended material into a material discharge pipe (8) and through an outlet duct (9) having a flanged end (10) for mounting the blender (1) on a processing line such as a plastics extruder. The mixing chamber (5) is mounted on a cantilevered support platform (12) on a base plate (140) of the frame (2) and cooperates with a load cell (15) mounted on the base plate (14) to provide a measurement of the weight of the mixing chamber and materials therein to determine the weight of the materials within the mixing chamber.
A blender has a mixing chamber for reception of materials to be blended. A mixing screw is mounted at a bottom of the mixing chamber for mixing materials within the mixing chamber and delivering mixed materials to an outlet feeding a processing line. Heaters are mounted within the mixing chamber for drying blend material in the mixing chamber.

A blender has a mixing chamber for reception of materials to be blended. A mixing screw is mounted at a bottom of the mixing chamber for mixing materials within the mixing chamber and delivering mixed materials to an outlet feeding a processing line. A baffle is mounted at the outlet extending about the mixing screw. The baffle inhibits upward movement of material at the outlet tending to cram material into the outlet.
