Vulcan® Frac Sand Drying System - For years now, specialized sands known as frac sands have been utilized to augment the production of natural gas and oil from wells. The mining and processing of sand for hydraulic fracturing, or "fracking," has grown into a booming industry worldwide.
The American Petroleum Institute (API) has specific criteria that must be met for frac sands, including weight percentage, sphericity and roundness, crush resistance, acid solubility and turbidity. To ensure that the quality of sand is acceptable, mining companies wash and dry the frac sand to rid it of all possible impurities. To meet API standards, frac sand particles must be well rounded and relatively clean of other minerals and impurities. High-purity quartz sands are common in the U.S., but most silica sand deposits are already being exploited because of the numerous uses for the material in a variety of industrial applications, including glass making and filtration media.
Rotary dryers are the most proven and preferred method to dry frac sand. A varying TPH rate can often have a substantial effect on the efficiency of the drying process. A rotary dryer allows the user to vary the mass air flow for different moisture content levels or operation at lower throughputs.
Dryers can be utilized at both the beginning and the end of the fracking process. Prior to its transportation to and use at a job site, frac sand must be dried and treated. After the process is completed, the waste fluids that remain form a sludge. Dryers can extract the liquid from this sludge and turn it back into a solid for proper disposal.
Worldwide Recycling Equipment Sales, LLC in Moberly, Missouri, can supply a full range of equipment to dry, sort and move frac sand. Our new and used dryers are designed specifically to dry frac sand, making the material easy to transport, separate and handle. We can size and build a dryer to best suit your specific project needs.
Our Vulcan® Drying Systems consist of a correctly sized drum and a burner mounted in a co-current configuration. After passing through the dryer, the dried frac sand is discharged to a transfer conveyor for further sorting and separation. The vapor from the process is pulled through a cyclone that is specifically designed to deal with the fine frac sand dust, as well as a high-temperature baghouse which removes all fine particulates from the vapor stream. All ductwork, cyclone and other high-wear areas in the system have abrasive resistant plates to reduce lifetime wear and maintenance costs.
Our Tuffman® Trommel Screens and Tuffman® Heavy Duty Conveyors can be used for sorting and transporting frac sand.
Worldwide Recycling Equipment Sales, LLC specializes in the remanufacture and reconditioning of used equipment, incorporating used components into custom-designed solutions for specific applications like frac sand drying. We also manufacture new dryer systems under the name Vulcan®. Our qualified and knowledgeable staff can design and build systems specifically for drying frac sand and a variety of other products. Vulcan® Systems are custom-manufactured with feed systems, rotary kilns, cyclones and baghouses best suited to the material. These specially designed systems can be equipped with a trunnion or chain drive, longer combustion flights to improve the development of the burner's flame and a moving slinger belt. The rotary dryer can be insulated to decrease fuel costs. Our services include set-up, commissioning, training and maintenance support services over the lifetime of your project.
