Aggregate Bin — Compartmented Aggregate Hopper

The General Makina aggregate bin is a compartmented steel hopper that stores sand, gravel and crushed-stone (aggregate) fractions in separate cells and feeds a concrete batching plant under control. Each bin holds a different aggregate size; pneumatically driven bin gates open under automation control and material drops onto the weigh belt. A load-cell scale performs smart dosing.

Working principle

• Loading: a wheel loader or truck fills the bins directly from a ramp; feeding via an aggregate pre-feed unit or a conveyor belt is also possible.
• Storage: each bin holds a separate fraction (0-5, 5-15, 15-25 mm, etc.).
• Dosing: the pneumatic gate opens and material discharges onto the weigh belt; the load-cell scale cuts off at the target weight.
• Vibro motor (optional): a per-bin vibro motor keeps wet or sticky material flowing.

Technical specifications

Bin capacity ranges from 10-50 m³ and total stock from 20-500 m³. The body is bent plate of 12-10-8 mm with a hinged side door. It ships to international transport standards, installs easily and carries a 1-year warranty plus 10-year spare-parts guarantee.

Mobile vs stationary bin

The mobile bin is chassis-mounted, fast to move and matches mobile plants. The stationary bin is for larger cells (up to 4×30 m³) and high-tonnage production on a permanent foundation.

Applications

• Aggregate feed for concrete batching plants
• Cold-aggregate silo equivalent in a mechanical (plent-mix) plant
• Continuous high-stock production (up to 500 m³)
• Vibro-motor bin for wet or sticky aggregate

Single-supplier bridge

The General Makina aggregate bin is fed by our own crushing-screening output and in turn feeds our own batching plant — one supplier, one chain. It offers up to 500 m³ of stock and 2-8 bin flexibility. Global crusher giants such as Metso, Sandvik and Kleemann do not offer batching-plant integration; we deliver the whole line from one hand.
