Crusher

A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, sand or rock dust.. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.

Concrete Recycling

Due to the small proportion of fractions smaller than 2 mm, the double-roll crushing technology with special crushing tools is excellently suited for the production of aggregates for concrete. For feed grain sizes of e.g. 22/100 mm, a product grain size of less than 22 mm can be produced with a sand content of between 20% and 25%.

Effect on screening of the particle distribution of the feed. The particle distribution of the feed has an essential impact on purity. See three examples in figure 1. In each one of them the efficiency is 90 %, but the undersize proportion of the coarse fraction varies (3.2 %, 9.1 %, 23 %). Effect on screening of the chosen screen hole size

Stockpiling

Raw materials pass through a vibrating screen box that contains different screen and mesh sizes. The material falls through like a sieve, and each rock size falls onto an attached conveyor, which stock piles each product, organizing them at the end for hauling. Screening can be used to create sand, gravel, crushed stone, coal, and topsoil.

Classification of Aggregates Raw Materials

The aggregates row materials are natural stones, which are mainly consist of three kinds of rocks: sedimentary rock, igneous rock and metamorphic rock..
