PROCESS AND DEVICE FOR INTRODUCING ADDITIVE MATERIALS IN A RECEPTACLE AT THE AREA OF HIGHEST PRESSURE

摘要

The invention relates to a method and a device for introducing and/or adding non-dry-powder additive materials and/or coating materials with a liquid, solid, semi-solid, or paste-like consistency or in suspended or emulsified form, for example, peroxides, fats, waxes, IV improvers, polymers, or similar materials, to an existing lumpy or particulate material which is moved and mixed, and optionally warmed and reduced to small pieces in a receptacle and/or compressor (1), said material being in particular polymer particles and/or flakes, wood fibers, paper cuttings, or similar materials. According to the invention, the additive material is introduced below the level of the material and/or material particles already in the receptacle (1).

主权项

1. A device for introducing and adding non-dry particulate, additives, or coating stuffs of a liquid, solid, semi-solid, or pasty consistency to a lumpy or particulate material, the device comprising:
at least one receiving receptacle or cutting condenser comprising:
a lateral wall,at least one mixing tool disposed inside the receptacle or cutting condenser, wherein the at least one mixing tool moves the material, and at least one feeding device for adding the particulate, additives, or coating stuffs, wherein said feeding device is disposed on the lateral wall and displaced vertically above an upper edge of the mixing tool such that a vertical gap is present between the feeding device and the mixing tool upper edge, and wherein said feeding device is arranged in a region of the lateral wall such that during operation the at least one mixing tool is operated to move the material above the gap to communicate with the feeding device such that said material exerts maximum pressure onto the region of the lateral wall where said feeding device is positioned.
