Rubber Grinding & Pulverization

Granulating of Caoutchouc Bales on the Ultra-Granulator™ PS-C with integrated Guillotine

For the economical size reduction of difficult-to-grind caoutchouc bales like natural - or buthyl caoutchouc in only one grinding step! Production of a flowable granulate allowing for much shorter dissolving and mixing time as well as energy saving kneading time.

Materials that can be processed: Economical size reduction of natural- and synthetic rubber of any kind.

Consistency of the feed material

The feed material can be in the form of bales, sheets, fibers, chips or crumbs, vulcanized or unvulcanized, with or without textile plies.

Decisive advantages

High economic efficiency due to saving a separate working step thanks to the integrated guillotine
High-performance guillotine hydraulics ensuring high cutting power
Cutting rate adjustable per minute
Special rotor for gentle treatment of the material
Knives pre-set outside of the machine
Grinding chamber well accessible for cleaning
Sturdy and reliable steel construction

Method of Operation

Size reduction from a standard size bale to a particle size smaller than 10mm, can often be accomplished in single step with materials like, NBR, SBR and EPDM. The Rubber Bales are fed either by hand or through conveyor belt into the cutting chamber and directly granulated to desired size. Particle size is determined by the screen size, which is usually has 10mm holes. The ground material is thereafter pneumatically conveyed to the bagging station.

The special infeed chute is equipped with 'bale cutting attachment' and patented shuttle flaps to guide the optimum and dosed material intake.

Application

For the size reduction of rubber bales whether natural or synthetic, special guillotine rotor is designed, without a traversing shaft and high - momentum flywheel. In addition to it, a specially designed infeed chute, equipped with a bale cutter, is also critical to guide the material towards the cutting chamber ensuring optimum feeding.
