Aggregate Drying - Triple Green Products

The heat source used for a Aggregate Dryer either uses natural gas or propane gas. Although this fuel source does work it is VERY inefficient and costly. For example, Propane gas – consists of 82% water and Natural gas – consists of 66% water. This means that this water/moisture turns into water vapor when burnt. All of this moisture is now being introduced into the products that are intended to be dried.

New Aggregate Drying Facility At Eaton Hall Agg

To facilitate drying of the aggregates before delivery to the bagging plant, the 1.5m diameter x 9.0m long dryer was specified to dry 14–6mm and 5–1mm aggregate blends with 1.2–2.6% and 5.3% moisture removal, respectively, at a rate of 45 tonnes/h, and also top dressing with 8% moisture removal at 30 tonnes/h. The energy requirement for 1.2 % moisture removal at 45 tonnes/h was calculated at 3.6

Rotary Dryers - FEECO International Inc.

Rotary dryers are a highly efficient industrial drying option for bulk solids. They are often chosen for their robust processing capabilities and their ability to produce uniform results despite variance in feedstock. Rotary dryers work by tumbling material in a rotating drum in the presence of a drying air. They can also be indirectly heated to avoid direct contact between the material and processing medium.
