The rotary drum dryer is suitable for drying woody biomass, agricultural products, and municipal solid waste (MSW). For the production of alternative fuels as well as in the area of waste-to-energy, ANDRITZ Vandenbroek rotary drum dryers are applied to decrease the moisture of the material to the desired level fo downstream process steps.
The ANDRITZ SEPARATION belt dryer/cooler BDC is available with gas-, oil-, or steam heating and can be applied for bulk material, food, or chemical products. The drying of the product takes place on a ventilated conveyor belt. Depending on the type of product we can offer either a single-belt dryer or multi-belt dryer.
Municipal sludge drying and granulation using waste heat. The patented ANDRITZ AG belt drying system (BDS) is characterized by its flexibility and ability to use a wide range of energy sources, particularly low-grade waste energy. BDS can be used for drying a broad range of products, such as industrial and municipal sludge, cow manure, biomass, as well as pre-treated municipal solid waste.
Drying and cooling take place in the product chamber, only by convective heat and mass transfer between the fluidization gas and the product. Two different designs are available, for normal and high temperature applications.
The fluid bed drying system with direct feeding converts dewatered sludge into almost dust-free granules with > 90% DS. The thermal heat for evaporation of the water is transferred indirectly by a heat exchanger immersed in the fluid bed. The fluid bed dryer is integrated into an inert gas loop system.
The ANDRITZ drum drying system, DDS, dries and granulates different types of municipal, industrial, and agricultural sludges. The dewatered sludge is granulated in a mixer tailored to the application. It is then dried in the triple-pass drum (three concentric cylinders revolving around a joint axis) in a convective drying process to < 10% residual moisture. The sludge is conveyed pneumatically by the stream of hot gases, ensuring an evenly dried,...
Drying and cooling combined in a single unit. This type of fluid bed is used for polymers and other temperature-sensitive products, especially of small particle size, mainly for high line capacities. It is characterized by the stationary design of the fluid bed without rotating and vibrating parts, resulting in higher operating availability and lower maintenance costs. In addition, different types of heat exchangers are incorporated in the fluidized...
The spray granulation process converts a water-containing solution, paste or suspension or a melt into a granule. The granulation and the drying processes take place at the same time. Any kind of crystallization and mechanical dewatering equipment can be replaced by an SGS type fluid bed. The final product granules are dust-free and easy to handle.
