The cold batching system is employed for the storage and delivery of particular sand and aggregate fractions. The cold batching system consists of particular hoppers, feeder belts, a collecting belt conveyor and a discharging belt conveyor. The cold batching unit may comprise also a service platform with an access ladder or stepladder.

The hoppers, in standard versions, are produced in the capacities ranging from 6 to15 m3 and are provided with suitable supporting steel structures. However, on customer‘s request, the hoppers of customised storage capacity may be supplied. The hopper may be fitted with a grate and vibrator assembly protecting the hopper from the access of oversized material lumps. Hopper contents may be protected from weather effects by a hinged cover.

The batching of individual fractions is provided by a feeder belt, driven by an electric motor with frequency-controlled speed. Alternatively, a scale belt may be used. The feeder belt feeds the batch material to a collecting belt conveyor, which transports it to discharging belt and then directly into the drum drier.

The surface treatment of steel structures of concern is made with an epoxide or polyurethane coating system. All the service platforms, stepladders, ladders and railings are hot-dip galvanised.
