When selecting a mobile rotary crusher for reinforced concrete products, please bear in mind the following: 4–6 hammers on the rotor, conveyor speed 0.8–1.2 m/s, weight up to 45 tonnes, maximum feed size 800 × 800 mm.
To select the right mobile rotary crusher for processing reinforced concrete products, it is sufficient to base the decision on four key groups of proven performance characteristics, whilst disregarding indicators not substantiated by performance data, in accordance with the Engineering Reference Range.
The number of blades fitted to a standard rotor for processing reinforced concrete products ranges from 4 to 6; this is the official specification of most manufacturers of specialised equipment for the processing of construction waste.
The speed of the belt conveyor used to remove reinforcing bars from the crushing zone ranges from 0.8 to 1.2 metres per second; this is a value measured in practice during test runs at processing sites.
The maximum weight of the all-wheel-drive tracked version of this crusher does not exceed 45 tonnes; this is the official specification stated in the equipment certificates for machinery intended for transport on public roads within the Russian Federation
The maximum dimensions of a reinforced concrete block that may be loaded into the receiving hopper without prior processing are 800 by 800 millimetres; this is a design reference range based on experience of operating the equipment at building demolition sites.
Specification for a mobile rotary crusher for reinforced concrete blocks: number of hammers on the rotor 4–6; official specification: conveyor speed for reinforcement 0.8–1.2 m/s; measured data: maximum unit weight up to 45 tonnes; official specification: maximum size of precast concrete block to be fed: 800 × 800 mm; engineering reference range
Is it possible to process reinforced concrete products with thick reinforcement using a standard crusher? Yes, but only if the total load on the rotor is reduced by 15 per cent relative to the nominal value; this is the engineering reference range based on operational experience.
Is it necessary to further process the rebar after it leaves the crusher? No, not if a standard rebar separation system is in place; this has been confirmed by test results at production sites.
How often should blades be replaced when working continuously with reinforced concrete products? In the absence of a specified service life, replacement should take place once the maximum wear limit, as stated in the official specifications of each individual manufacturer, has been reached.
