Abstract

This paper describes the technological process of pressing pulverized biomass and analyzed different forms and dimensions of the hole in the matrix pelleting presses depending on the type of raw material for molding. Matrices may be flat and annular, and forms openings on their conical, square, oval, and cylinder. Dimensions of the matrix along the length of the channel can be constant and variable. The opening of the mouth of the channel can be extended in order to avoid build-up of material at the entrance of the channel, i. e. to reduce the resistance of the material in the pressing. The ratio of the diameter and length of the channel to determine the degree of compression molding material. Also, the extension of the output section of the canal is intended to reduce the resistance of molding materials. Shapes and sizes of the channel on the surface of the rollers for compacting biomass depending on the type and condition of the raw material for molding. It was noted that certain types of plant material compressed differently and therefore require different structural characteristics matrix for pressing biomass.
