Oliver 48X48MA Destoner

The Oliver 48X48MA Destoner is a professional-grade, high-capacity density separator designed for precision sorting. Belonging to Oliver’s renowned Master Series (MA), this machine is engineered to efficiently remove heavy contaminants—such as stones, mud balls, glass, metal, and weed seeds—from lighter, dry bulk commodities of similar size.

Highly regarded across the seed, grain, food processing, and industrial recycling industries, the 48X48MA combines a generous deck surface area with automated, user-friendly controls to maximize purity and throughput.

Key Features & Capabilities

Strategic Stratification: Using a precise balance of fluidizing deck air and eccentric vibration, the unit stratifies the incoming product flow, forcing heavier debris upward to the top of the deck while the clean, lighter commodity flows smoothly down the deck for discharge.

Patented Multiple Fan System: Rather than using restrictive air baffles, the 48X48MA utilizes a series of built-in, individually adjustable fans beneath the deck. This ensures an exceptionally uniform air pattern across the entire 48″ x 48″ separating surface while optimizing power efficiency.

Master Series (“MA”) Control Suite: * Integrated VFDs: Allows operators to safely make infinite, precise, on-the-fly adjustments to the deck speed to match changing product conditions.

Heavy-Duty Counterbalancing: Built with a counterbalanced frame that absorbs structural harmonics, virtually eliminating building vibration and significantly extending the lifespan of the bearings and overall machine.

Fast Setup Repeatability: Features clear adjustment gauges and an Accu-Flo feed gate to guarantee consistent, repeatable flow rates across different runs.
