A process and apparatus for manufacturing crumb and powder rubber. The process and apparatus include a cooling step, effectuated by cooling means, wherein the temperature of cryogenically cooled preprocessed rubber particles is controlled. The process and apparatus also include a grinding step, effectuated by grinding means, in which the degree of grinding, and thus the product particle size range, is controlled.

Process and apparatus for manufacturing crumb and powder rubber

A process and an apparatus for the comminution of foodstuff, especially phytosterol, particles to a particle size suitable for inclusion in liquid or solid foods.

Process and apparatus for comminuting phytosterol particles

A process and apparatus for comminuting rubber particles. In this process and apparatus rubber particles at a temperature below the glass transition temperature are introduced into a comminuting device concurrent with the introduction of an inert gas coolant at a temperature below about &#x2212;75&#xb0; F. The rubber particles are comminuted in the comminuting device at a rate proportional to the average particle size of the introduced rubber particles to an average size within the range of crumb or powder rubber particles.

Process and apparatus for comminuting particle rubber

A process and apparatus for making crumb and powder rubber from preprocessed rubber particles. The process and apparatus provides an energy efficient operation wherein the preprocessed rubber particles are dried, precooled, frozen, comminuted and sized using a closed cryogenic fluid cycle.
