A method includes feeding a heated polymer additive at a first temperature into a continuous mixer at a first feed rate. The method includes feeding a heated abrasive solid material at a second temperature into the continuous mixer at a second feed rate. The heated abrasive solid material and the heated polymer additive are mixed in the continuous mixer to form a first mixture.

A mixing and cooling system (1) includes a mixing and screw-extrusion machine (10) with a mixer (12) having a converging conical twin screw; a ram (30) that moves along the inside of an introduction hopper (24) of the machine; a roller nose system disposed just downstream of an outlet (25) of the mixer to form a sheet (112) of the mixture exiting the mixer; and a mobile sleeve or sleeves (34) that move in a linear movement relative to the outlet. The system also includes a cooling system with a spray installation(s) (102, 104) that delivers water at a predetermined rate to the sheet exiting the machine; a suction installation(s) proportionate to each spray installation; and at least one transport means (114, 116) that transports the sheet in a predetermined direction.

A charging system for feeding processing material to at least one extruder screw including a hopper configured to conduct the processing material along a feed direction to the extruder screw, and a material reservoir for the gravity-driven feeding of the processing material to the hopper. The charging system also includes a feeding device via which processing material recirculated at the hopper against the feed direction by action of the extruder screw can again be conveyed in the direction of the extruder screw together with processing material fed from the material reservoir.

An inclined belt conveyor capable of mixing particulate material, such as agricultural seed or fertilizer. Inserting a plurality of mixing baffles into the stream of the particulate material induces a backflow of the particulate material. In the case of wet, freshly treated plant seed, this backflow causes a mixing, polishing, and drying of the plant seed. The mixing distributes the seed treatment into an even coat by rubbing the individual seeds of the seed flow stream together. The inclined belt conveyor may also be used to blend multiple varieties or types of particulate material. The mixing baffles are oriented to induce backflow and sideways lateral movement and may incorporate a passage to allow increase particulate material flow rate. The mixing baffles can selectively deploy between an angle of 20 degrees to 70 degrees to enable the mixing inclined belt conveyor to have a transfer-speed-maximizing mode and a mixing mode.

The database connected to the controller controls the sorting and cleaning equipment, the grinding equipment, the powder grinding equipment, the mixing equipment, the pelletizing equipment, the drying equipment, the hot stir equipment, and the shaping equipment through transmission channels. In addition, the present invention provides a method of manufacturing for making synthetic building materials using plastic wastes combined with industrial and agricultural scrap.

A pelletizing apparatus for the production of pellets from a melt flow comprising a pelletizer (12, 112), a cutting chamber (14, 114, 172), and a suspension structure (4, 104) for suspension of the pelletizer (12, 112) and/or the cutting chamber, wherein the suspension structure (4, 104) has a stationary portion (8, 108) and a portion (6, 106) connected rotatably about an axis of rotation (18, 118) to the stationary portion (8, 108) by means of a joint (16, 116).

According to the invention it is proposed that the pivotable portion (6, 106) has a substantially horizontal support arm (20, 120) which extends from the axis of rotation (18, 118) and has a distal end (22, 122), wherein in the region of the distal end (22, 122) the pivotable portion (6, 106) has a support (10, 110) adapted to support the pivotable portion (6, 106) in a vertical direction (24, 124).

Embodiments of an invention disclosed herein relate to devices, processes, and systems for processing one or more polymers.

A die plate changing system holds first and second die plates and selectively transitions the first and second die plates into and out of communication with a material source. The die plate changing system has a frame having a body defining a first recess that receives the first die plate and a second recess that receives the second die plate, where the frame is heats the first and second die plates when the first and second die plates are disposed in the first and second recesses, respectively. The die plate changing system also includes a movement assembly operably coupled to the frame and that selectively moves the frame between a first position, where the first die plate receives material from the material source, and a second position, where the second die plate receives the material from the material source.
