Description

Vulcan 25 TPH Gypsum Dryer System - new or used Vulcan 25 ton per hour Gypsum Dryer dries mined gypsum, pelletized gypsum or gypsum for use in wallboard. This equipment has been designed to reduce the moisture content in gypsum through a direct fired rotary dryer. Particulate matter emissions (dust) are controlled using a high-efficiency cyclone and pulse jet baghouse. The system includes the following componentry:
Material Feed System:
Specially lined feed hopper, an optional classifier and Tuffman® transfer conveyor(s)
Rotary Dryer:
Direct fired rotary dryer with drive, seals and industrial burner
Dry Material Discharge:
Flap-gate drum discharge and Tuffman® conveyor
Air Pollution Control Devices:
High-efficiency cyclone, baghouse and induced draft fan
Controls:
Push button control panels or programmable logic controllers, PLC, options available
PROCESS DESCRIPTION
The Vulcan® 25 TPH Gypsum Dryer is fed wet gypsum to a high slip lined hopper, which feeds a material classifier. This unit acts as a pre-conditioner to increase the effectiveness of the drying step. Once prepped, material is gravity fed to a Tuffman® belt conveyor and then a final conveyor which transports the material into the drum.
The Vulcan® direct fired rotary dryer is the workhorse of the drying industry. A simple unit, the inclined rotating cylinder, is fitted with an industrial burner radiating heat down the center of the drum. Lifting flights pick up the material and then cascade it into the hot combustion gases. This intimate mixing provides the heat required for the phase transformation of liquid water into steam. As material progresses through the drum, more and more water is vaporized until the dried gypsum drops out of the gravity discharge and onto a Tuffman® conveyor. Vapors, combustion gases, steam and tramp air entrain dust particles known as particulate matter, which must be controlled.
The first step in controlling particulate matter is our custom-built Vulcan® cyclone dust collector. Our cyclones utilize centrifugal force to separate the heavier solid particles from the vapor stream. This acts as a pre-conditioner to the baghouse for overall reduced particulate matter emissions. Remaining entrained dust is routed to a pulse jet baghouse. A pulse jet baghouse or fabric filter dust collector operates similarly to an air filter on an engine. Air is pulled through a filter-media, which collects dust while the gases pass through. Baghouses have the ability to remove particulate matter greater than 1 micron with more than 99.99% efficiency, which will help to meet any environmental regulations on air pollution. The cleaned dust is then pushed out the stack of the system through an induced draft fan.
