Portable Screening and Crushing Equipment for Producers

For nearly four decades, Sand Science Inc. in Yemassee has been the trusted partner for aggregate producers, contractors, and recyclers throughout the Southeast who need the right machine for every job. The company's extensive equipment portfolio spans trommel screens, vibrating screens, jaw crushers, stackers, conveyors, and portable washing plants — giving operators a single source for complete material processing setups. Choosing the correct equipment for a given feedstock, whether that's gravel, mulch, compost, construction debris, or fine sand, determines how efficiently an operation runs from the first hour onward. Sand Science draws on more than 40 years of field knowledge to guide every equipment recommendation. Robust, high-throughput aggregate processing solutions must be mobile enough to relocate between projects without costly downtime. That's why Sand Science keeps a ready inventory of new, used, and rental machines at its Yemassee, South Carolina facility for fast deployment. The company's material screening solutions are purpose-built for applications ranging from topsoil and biomass to C&D waste and washed aggregate. With around-the-clock availability, proactive site visits, and rapid service response, Sand Science ensures production keeps moving no matter the challenge.

Matching the Right Processing Equipment to Every Application

Trommel and Vibrating Screens Tailored to Your Feedstock

Choosing the proper screening technology is the foundation of any efficient material separation workflow. Sand Science stocks a range of portable trommel screens — among them the Revolver RT508 and Roto-Screen 454 — as well as vibrating screens built to handle topsoil, compost, mulch, fine sand, and mixed aggregates. Trommel drums are especially well-suited to wet, sticky, or high-moisture feedstocks that cause flat-deck screens to blind and lose efficiency, while vibrating screens deliver precise multi-fraction separation in dryer, more consistent materials. Before any equipment ships, the company's application specialists assess your feedstock characteristics, target product sizes, and required throughput rates. This consultative approach to aggregate processing means operators start producing usable material from the very first pass, rather than spending days or weeks fine-tuning settings on-site after delivery.

Jaw Crushers, Stackers, and Full Processing Circuit Configurations

A well-rounded aggregate operation needs more than screens — it demands dependable size reduction equipment and smart material transport to keep product moving efficiently. Sand Science Heavy Equipment includes Barford track-mounted jaw crushers engineered to reduce rock, reinforced concrete, and mixed construction and demolition rubble into specification-sized aggregate fractions without leaving the job site. Integrated with Barford stackers and Kafka wheeled conveyors and picking stations, these units create complete processing circuits that cut down on double-handling and dramatically increase output rates. Exploring Sand Science Inc.'s Yemassee page reveals the full range of available crusher capacities, conveyor lengths, and rental package details. Because every site presents different spatial and material constraints, circuits are designed for modular flexibility — operators can expand or reconfigure the layout as project volumes shift over the course of a season.

Recycling Equipment, Portable Washing Plants, and Try-Before-You-Buy Rentals

Converting waste materials into marketable products is one of the strongest growth opportunities available to modern aggregate and demolition operators. Sand Science supplies purpose-built recycling systems for C&D debris, biomass, and blended construction waste streams, complemented by RD Olsen portable washing plants that process raw material into clean, specification-grade sand and gravel. Short- and long-term rental programs give operators access to equipment when capital budgets are constrained, and the company's Rental Purchase Option allows full machine trials under actual production conditions before any purchase commitment is made. This approach to equipment acquisition reduces financial exposure for operations managers and provides concrete performance data from a team's own site and material type — so there are no surprises once the purchase decision is finalized.

Frequently Asked Questions

The product lineup is designed to process topsoil, sand, rock, gravel, mulch, compost, biomass, C&D debris, and a variety of recycled construction materials. Application specialists work with each customer to match the equipment to their specific feedstock, moisture levels, and target output sizes.

Yes. Based in Yemassee, South Carolina, the company regularly serves aggregate producers, contractors, and recyclers throughout the Southeastern United States and beyond, delivering equipment, conducting site visits, and providing responsive support wherever projects are located.

Sand Science offers a Rental Purchase Option that allows customers to operate equipment in live production conditions prior to buying. A portion of rental payments can be credited toward the final purchase price, lowering financial risk and confirming the machine is the right fit for the application before full capital commitment.

Sand Science keeps an in-stock inventory of new, used, and rental machines at its Yemassee machinery yard, enabling rapid delivery. Operators often take possession of equipment in a matter of days rather than waiting extended periods for factory lead times to clear.

The company stocks Barford track-mounted jaw crushers in several sizes suited to rock quarrying, concrete recycling, and C&D debris reduction. These mobile units pair naturally with conveyors and stackers to form a complete on-site crushing, processing, and stockpiling circuit.
