Novel combined equipment suitable for granulating/crushing high polymer materials by grinding method

Abstract

The invention provides novel combined equipment suitable for granulating / crushing high polymer materials by a grinding method. The equipment is characterized in as 1-1 or one or combinations of 1-1, 1-2 and 1-3, wherein 1-1, combined sub-equipment A is at least provided with a grinding mechanism, the grinding mechanism at least can select high polymer materials with the bulk density larger than or equal to 0.06 kg / L and waste plastic films or / and waste agricultural plastic films which are coarse enough to pass through 2-mesh sieve holes and are discarded from regeneration of waste paper as calibration objects, and when the calibration objects enter the grinding mechanism at a time, the ratio of the product of the machine passing object yield W unit kg and the time T unit h to the rated power P unit kw of a motor of a main shaft driving the grinding mechanism to work is calculated as Wkg.Th / Pkw>=1.30kg.h / kw or Wkg.Th / Pkw>=3.90kg.h / kw; and a discharged product obtained by the calibration objects passing through the machine at a time at least contains particles which can pass through a 10-mesh sieve but not pass through a 20-mesh sieve, the particles are in infant silkworm-shaped strip shapes, and the length / diameter ratio of the strips is at least within the range of 3 / 1 to 15 / 1.

Description

technical field [0001] The present invention proposes a new combination equipment suitable for granulating / crushing polymer materials by grinding method, which relates to processing equipment for granulating / powdering plastics and rubber in polymer materials, especially suitable for thermoplastic plastics or / and The processing of finely grinding elastomers at room temperature but forming granules, or the processing of thermosetting elastomers grinding and forming fine powder at room temperature belongs to the technical field of machinery for granulating / powdering processing of polymer composites / compositions. [0002] technical background [0003] In the industrialized technology of processing elastomers or / and plastic materials in polymer materials into rubber-plastic composites, if the selected elastomers are cured waste vulcanized rubber, etc., they must be crushed or / or and replasticization; for the operation of filling powder fillers into new thermoplastic elastomers and...
