Rotary Dryers and Coolers
Heyl & Patterson Renneburg Rotary Dryers and Coolers are some of the most versatile rotary dryers and coolers available, and are considered the workhorses of the powder and bulk solids processing industry. Able to effectively handle a broad range of material, including powder and bulk solids and liquid sludges, the Renneburg Rotary Dryer can be specified according to starting and final moisture content, product temperature, drying air temperature, air velocity and retention time of the material – in order to meet and exceed your specific application requirements. Based upon your needs, several different cooling design options are also available, including counter-current air swept, internal and external water-cooled or a combination of air and water-cooled.
Fluid Bed Dryers and Coolers
Heyl & Patterson’s Renneburg Division manufactures some of the largest Fluid Bed Dryers in the world, and are among the most efficient and cost effective dryers and coolers on the market. Designed to process free-flowing material, such as minerals, chemical, plastics, wood products, grain and waste, suspended in a rising flow of air or gas, it uses an energy efficient fluidizing method that causes the material to act like a fluid. In turn, this provides a high rate of heat transfer while gently handling the solids. It also provides lower capital equipment and operating costs as a result of its efficiencies. Offered in two types, Trough-Type Fluid Bed and Circular Type Fluid Bed, each unit includes a standalone or integral cooler that can be specified with one of the following designs: trough air swept, in-bedplate or pipe coils or evaporative water spray.
Flash Dryers and Coolers
The Renneburg Flash Dryer is used for drying high moisture, temperature-sensitive material, including chemicals, minerals, sludge, food stuffs, plastics, gypsum and wood fibers, with high thermal efficiency. Using the principle of selective processing, this unit ensures that every particle’s resistance time is proportional to its size and weight, resulting in a high quality product that’s free of physical and chemical degradation. We also offer a Rotacurrent and Venturijet design.
