Abstract

The article addresses the problems of reduction and utilization of waste in production of high-quality road metal 5–20 mm in size. The concept of economic utilization of screenings is formulated. A nonwaste technology is offered for volcanic rock processing. The offered nonwaste technology includes a number on intercoupled process flows that enable:
1. Reduction in the amount of screenings after rock crushing (fractions 0–5 mm) by over 10% owing to vibratory crushers as compared with conventional crushing in the standard cone and centrifugal crushers;
2. On-site utilization of screenings (fractions 0–5 mm) and pit-run fines (fractions 0–20(40) mm), which allows production of building materials based on the following engineering solutions:
- Reshaping of particles in vibratory crushers;
- Drying and classification of artificial sand into narrow fractions using modified screens;
- Introduction of classified artificial sand in manufacture of vibro-pressed concrete products;
- Introduction of dust fraction (0–0.16 mm) in production of granulated light-weight aggregate for concrete.
The offered technology is totally in line with the worldwide recognized principle of civilized treatment of any waste material—3R technology where 3R stands for Reduce, i.e. waste reduction, Reuse, i.e. repeated usage, and Recycle, i.e. processing toward production of a new commodity.
This work was carried out within the State task in the scientific effort sphere.
