Mixer Towers

Amomatic mixer tower and hot elevator have been developed and tested in tough Scandinavian conditions, with extremely hard stone aggregates. The standard range of modular Amomatic mixer towers has capacities up to 300 tons per hour. The mixer tower modules are designed for easy and fast erection and dismantling.

Construction

The mixer tower is equipped with a shaft screening or an impact screening unit. The hot aggregate silos are equipped with level indicators connected to the AmoControl system. For best dosing accuracy the discharge gate for fines fraction closes in two steps. All sites exposed to higher than normal wear are protected with the Amomatic Antiwear System. The aggregate scale is fully enclosed and dustproof with two pneumatically operated gates for fast discharge into the mixer. The aggregate scale hopper is supported by four weighing cells. The filler scale hopper is supported by three weighing cells. For the fast and even discharge of the filler into the mixer, there are three pneumatically operated clack valves at the bottom of the hopper. The bitumen weighing tank is insulated and the bitumen tank, pump, valves and the piping are all electrically heated. The weighing tank is supported by three weighing cells.
