PROCESS DESIGN OF DRYERS (PROJECT STANDARDS AND SPECIFICATIONS) Page 2 of 48 Rev: 01 April 2011 SCOPE This Project Standards and Specifications is intended to cover minimum requirements for process design of dryers used in oil, gas, and petrochemical process plants. Although, as a common practice, dryers are seldom designed by the users, but
Sure Plate Continuous Disc Dryer. ANCO Sure Plate Continuous Disc Dryer utilize indirect, continuous drying combined with maximum heated surface area in a minimum space. The rotor consists of a tubular shaft with multiple disc to heat and transport product. ANCO also offers a Sure Plate design with no external welds on the central heating surface.
ABSTRACT An investigation of the thermal drying of lignite has been carried out, by using an indirect heat pilot rotary drum. The process aims at the production of dry lignite and clean steam as part of a gasification procedure. Both flighted and bare drum modes have been employed. Temperature profiles along the dryer length, the amount of evaporation (moisture conversion) and the solids ...
EPA United States Environmental Protection Agency Biosolids Technology Fact Sheet Heat Drying DESCRIPTION Heat drying, in which heat from direct or indirect dryers is used to evaporate water from wastewa ter solids, is one of several methods that can be used to reduce the volume and improve the qual ity of wastewater biosolids.
If it is not suitable to apply heat direct to heat and dry the raw material, then rotary dryers of indirect heating design can be furnished so that the heated hot gases will not come in direct contact with the wet raw material. Rotary Dryer is a simple, inexpensive unit for reducing the moisture content from the wet material. Several types of ...

Dryers typically use special rotary or spherical disc valves for solids discharge handling. The solids can also be directly discharged to a bin hopper or vessel depending on the process requirements. The dryers are indirectly heated by steam or hot oil and can be operated semibatch wise or continuously.
GK Rotary Dryers use rotary motion to lift and cascade your material through the hot gas stream, evaporating moisture evenly. Dryers can be designed using various drying technologies, including direct drying in countercurrent or cocurrent flow, or indirect drying, utilizing external heat applied to the exterior of the drum shell.

If you're looking for used industrial dryers, Federal Equipment can help you. We have a large selection of used industrial dryers to choose from, whether you are looking for a used industrial rotary dryer, spray dryer, vacuum shelf or any other type of dryer.
Indirectfired rotary dryers are better suited for niche applications, and are ideal for processing dusty, fine Material of Construction materials, or materials that cannot be exposed to Unlike their directfired counterparts, which are drying air during processing.
Directheat rotary dryers can operate on fuel oils, natural gas, propane or coal. In addition, steamheated clean air and flue gases may be used as a heating medium. Indirectheat rotary dryers are available in steam tube designs and standard rotary models. When the standard rotary design is used, convection heat transfer is employed.
Rotary Vacuum Dryers offer clean, simple and effective method of drying wet cake, powder and even slurry. Labor and energy costs are minimal compared to tray dryers and product losses during handling are also negligible. Additionally valuable organic solvents can be conveniently condensed and recovered. Working Principle:
