Asphalt production. Dosing of additives to bitumen

When preparing bitumen mixtures used for asphalt production, it is necessary to dose special additives into the bitumen.

A single dose of the additive can range from 20 to 80 liters depending on the concentration of the additive and the grade of bitumen.

For small-scale production, this task can be handled by a drum pump using a flow meter.

or a measuring container (a cheaper option)

For large enterprises, a dosing scheme can be implemented based on stainless steel vortex pumps by ROVER or gear pumps from the WCB series.

Using a flow meter with a control signal, the pump will automatically shut off after a specific volume has been dispensed.

Or using the same pumps in combination with a timer relay.
