Loading and Delivery
Central Gypsum is committed to making the loading and delivery of your agricultural gypsum as smooth as possible. Throughout the season, we work alongside Bellini Bulk Haulage, our onsite operations contractor from Kalgoorlie, to ensure everything runs efficiently.
Bellini handles all aspects of the process—ordering, scheduling, pickup, and invoicing—so that you have a hassle-free experience tailored to your needs.
We use a TEREX Finlay 683 Screener with an Anaconda Stacker to screen the gypsum, and all loads are weighed by a trade-certified Trimble LOADRITE system to ensure accuracy. After loading, you’ll receive a receipt confirming the amount of gypsum.
Bellini Bulk Haulage can also help by delivering your gypsum directly to your farm, offering extra convenience during busy times.
We’re here to support you with dependable service throughout the season.
