Abstract

The present invention discloses a rapid test for determining particle attrition in which i) a particle is ground, ii) a sieve analysis is performed on the ground product, and iii) the result of the sieve analysis is compared to at least one reference value A comparison was made to classify the particle attrition where the particle was ground in a cutting mill.

Description

technical field [0001] The present invention relates to rapid wear tests of granules, preferably inorganic or organic granules, particularly preferably plastic granules, especially those used as filling materials for artificial turf. Furthermore, the rapid test of the invention enables the determination of the strength and adhesion of layers of material on surfaces or in interlayers of multi-layered particles. Background technique [0002] Plastic pellets are the typical form of supply of thermoplastics from raw material manufacturers to the plastics processing industry. Due to their free-flowing capabilities, they are bulk materials, like sand or gravel, and are therefore relatively easy to transport and further process. [0003] The use of plastic pellets as artificial turf infill material has been discussed in depth recently. For example, European patent application EP 1 416 009 A1 discloses the use of coated rubber particles as a dusting material or loose elastic layer...
