Drying systems for minerals and aggregates consume much energy, leading to high operational costs and low margins. Our high-efficiency fluid bed dryers typically result in energy savings of 30-60%, which makes the Ventilex the most energy-efficient of all drying solutions.
Drying / Mixing Before rock aggregate is mixed with other ingredients to make HMA, it is thoroughly dried. The drying and mixing process can be accomplished with one piece of equipment or the functions can be separated. Mixing can take place in a continuous process or in a batch process.
We can dry your products using far less BTU’s while also making your equipment far more productive. Let Triple Green Products put money back on your bottom line while increasing production. With the rising costs associated with using fossil fuels as a source of energy and the efforts being made to reduce carbon emissions, Triple Green .
Air Drying Ovens are useful for drying soil, aggregate, and fire-proofing samples as well as other procedures calling for air drying at room temperature. While the 105°F (41°C) maximum temperature is below 140°F (60°C) allowed for some procedures, drying is still rapid and efficient because of the high air flow of 1—4 air changes per minute.
heating and drying of aggregate. aggregate dryers, together with their associated equipment, are an essential part of asphalt plant performance. in aggregate drying, the purpose is to transfer heat to the aggregate and the associated moisture so that the aggregate temperature will rise and the moisture evaporate.
The drying process, though very energy-intensive, ensures that the asphalt will bind to the rock. Inside the drum the aggregate is kept in motion by shaped scoops called flights attached to the inner surface, which produce a “veil” of falling material. Better veiling action improves heat transfer and speeds drying, reducing fuel consumption.
ASTM C566, “Standard Test Method for Total Evaporable Moisture Content of Aggregate by Drying,” is applicable to both fine or coarse aggregate and is the most commonly used procedure. ASTM C70 , “Standard Test Method for Surface Moisture in Fine Aggregate,” is another test method but is only for use on fine aggregate.
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.
Drying Technology. The R-O2 Patented Drying Technology is a proven process that uses Reduced Oxygen Superheated Dry Steam as the medium for removing moisture. This offers great benefits to manufacturers of materials such as sands, aggregates and more. Low material discharge temperatures; 0% moisture of dryer material
A. Saturated-surface-dry (SSD) refers to the condition when the permeable pores of the aggregate are full of water but the surface is dry. SSD aggregates neither contribute nor absorb water from the concrete. Absorption is the moisture content of SSD aggregates. It is determined by weighing an SSD sample, then oven drying it and weighing it again.
