A secondary shredder can include a rotor assembly that employs a modular rotor design. Each rotor of the rotor assembly can include a number of blades that are symmetrical around a horizontal and a vertical axis. Each rotor can include a number of radial extensions forming gaps into which the blades insert. The blades can be secured within the gaps by wedges that apply an inward force against the blades when the wedges are secured into the gaps. The radial extensions and blades can include keyways into which keys insert to prevent the blades from escaping the gaps. The secondary shredder may also include a stationary knife assembly that includes multiple stationary knives that are positioned on the same side of the rotor assembly.

Disclosed is a grinding roller for waste tires and a multifunctional crusher having the grinding roller. The grinding roller comprises a roll shaft and a plurality of grinding components. The grinding components each comprise a grinding frame and grinding blocks mounted in grooves of the grinding frame. Each grinding block has a grinding surface that protrudes with respect to the grooves. Axial interval adjusting rings are disposed on the ring shaft for separating the grinding components at a predetermined distance to cut waste tires into blocks. The crusher comprises a box for housing the grinding roller. The box is provided with a material inlet and a material outlet. Axial blockers are mounted on the crusher to help grind waste tires into fine powder.

A machine or system and related method for breaking and reducing the bulk size of one or more objects and comprising: a frame, a reception chamber and a size reduction mechanism. The size reduction mechanism includes a drum rotatably coupled to the frame and configured to oscillate relative to the frame between a first position and a second position about a longitudinal rotational axis; a cutting member coupled to the drum and extending therefrom, the cutting member being configured to penetrate through one or more of the objects in the reception chamber during operation as the drum rotates from the first position to the second position during each oscillation cycle; and a breaking screen comprising a series of spaced breaking members configured to cause further breakdown of the one or more pieces of the one or more objects during operation as the drum rotates toward the second position during each oscillation cycle and forces the one or more pieces against the breaking members. An optional chute may be coupled to the outlet of the machine or system for further compacting and disposing of the bulk material output by the machine.

A system and method for freezing and breaking down tires or other materials is disclosed. The system and method for freezing and breaking down tires includes using a shredder to shred the tires, using a filter to screen the tire shreds, using a water sprayer to rinse the tire shreds, using a freezing tunnel to freeze the tire shreds before they are crushed into tire grains, using a magnet to remove any metallic fibers, filtering out any oversized tire grains for re-freezing and re-crushing, and using a separator to separate out any oversized or undersized pieces before bagging the final tire grains for re-use and recycling.

A crushing device for a waste tire and a multi-functional crusher therewith are provided. The crushing device includes a main shaft, a roll shaft main body fixedly arranged on the main shaft, and roll shaft blockers arranged at two axial ends of the main shaft; crushing components are arranged on the roll shaft main body; a plurality of roll shaft convex bodies are arranged on a periphery of the roll shaft main body along a circumferential direction; a roll shaft groove is formed between each two adjacent roll shaft convex bodies; the crushing components include tools, axial interval adjusting blocks and/or radial supporting blocks; a tool groove, corresponding to the roll shaft convex body, is provided at a bottom of each tool; and an axial interval adjusting block groove, corresponding to the roll shaft convex body, is provided on each axial interval adjusting block.

The present invention relates to a rubber-based substance for removing saturated and unsaturated fats, oils and petroleum products, as well as organic solvents from the aqueous surface, and/or an aqueous emulsion and aqueous solutions of organic solvents. In addition, the present invention also relates to a process for producing a given rubber-based substance. More specifically, the present invention relates to the application of this rubber-based substance for removing saturated and unsaturated fats, petroleum and petroleum products, as well as organic solvents from the water surface of open water bodies, including seas and oceans.

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).
