Využívání nových materiálů při třídění surovin na lomu Plešovice.

Abstract

In the production of crushed aggregates, gravels and mechanical concreted aggregates sorting is an important part of technology also, except the inherent process of crushing. Materials for the production of sieves for sorting developed in time from the perforated sheet-metal and wire sieves to the modern polyurethane sorting surface with a different construction and with a combination of used materials. An overview of used materials for sieves production and their comparison is worked up in the thesis. Utilization of polyurethane sieves is proposed subsequently in the sorting technology of industrial mineral and economic a ecologic influences of the proposal as well. An overall evaluation of polyurethane sieves using at the industrial mineral sorting at the Plešovice quarry is put down in the end at the thesis.
