Provided are a method and a device for recycling and granulating PP composite medical drip soft bags. The method includes: putting a fragment mixture of a recycled PP composite medical drip soft bag into a hopper; heating the fragment mixture to a predetermined temperature for kneading, filtering the heated fragment mixture, and then extruding the heated fragment mixture after filtering; cooling the fragment mixture; shaping and granulating the fragment mixture to form a plurality of particle materials; cleaning the particle materials; dehydrating the particle materials; vibration screening the particle materials according to different sizes; and outputting the particle materials with respective sizes to different storage barrels. This is used to recycle PP composite medical drip soft bags to achieve the effects of recycling, improving processing efficiency and creating friendly environment.

A system and method for processing objects having contaminating particles includes the steps of shredding the objects in a shredding chamber to form a plurality of shredded fragments, wherein the shredding chamber is arranged to be substantially combustion resistant, and removing the contaminating particles from the plurality of shredded fragments.

Systems, methods, and apparatuses for manufacturing micronized powder. The systems, methods, and apparatuses comprise pre-grinding processing, cryogenic freezing, and grinding of infeed material and warming, ferrous metal and fiber removal, accumulation, screening, and storage of micronized powder. Generally, the warming may involve recirculation of micronized powder through the warming apparatus. Further, the accumulation may permit the grinding and screening to occur at their respectively optimal rates, and the fiber removal, via use of a vibrating screener, may increase the purity of the micronized powder. In one embodiment, the micronized powder comprises micronized rubber powder (MRP).

A method and system for recycling wind turbine blades. A scalper scalps off balsa wood and foam from recycled composite chips, a lump breaker shatters the chips produced by the scalper, a hammer mill breaks fiber chips produced by the lump breaker to reduce the chips to strand clusters, a vibratory screen and cyclone air classifier or circular vibratory screener separate strand clusters of acceptable size from larger strand clusters that require repeated processing with a hammer mill, another vibratory screen and cyclone air classifier or circular vibratory screener further separate strand clusters of acceptable size from larger strand clusters that require repeated processing with a hammer mill, and a granulator pulverizes the resulting fiber strand into micro-fibers that can be used as reinforcement fibers.

A resin recovery method comprises a crushing step, a sieving step, and a collecting step. In the crushing step, a resin-product-equipped harness is loaded into the crusher having a striking portion that rotates about a predetermined axis to crush the resin product with the striking portion into resin pieces. In the sieving step, the harness and the resin pieces are loaded into a sieving device having an upper sieve and a lower sieve provided below the upper sieve, from above the upper sieve. In the collecting step, the resin pieces that have passed through the upper and lower sieves are collected.
