Bunkers and Hoppers — Controlled Intake and Buffering
The bunker is the plant's front door: trucks and loaders dump material in seconds, the process consumes it steadily for hours. Pro Makina designs receiving bunkers and buffer hoppers whose discharge geometry, wear protection and feeders match your material — so intake never becomes the bottleneck.
Design Principles
A receiving bunker takes impact loads, abrasion and irregular dumping; its grid keeps oversize out, its walls need wear plates where material strikes, and its outlet must release cohesive material without manual help. Buffer hoppers above dosing equipment have the opposite duty: small volume, but absolutely steady discharge into the feeder below.
Both duties come down to geometry and material data: hopper half-angles, outlet dimensions and wall surfaces engineered against your material's cohesion and moisture range — supported by vibrators or aeration only where geometry alone cannot guarantee flow.
Typical Applications
- Truck receiving bunkers for raw materials and waste
- Loader-fed intake hoppers in compost and recycling plants
- Buffer hoppers above weigh feeders and packing scales
- Day bins for additives and recycled streams
Technical Features
Anti-bridging geometry
Outlet sizes and hopper angles derived from material flow properties.
Wear protection
Replaceable liners and impact zones for abrasive intake duties.
Discharge equipment
Screw, belt or vibro feeders integrated under the outlet.
Level monitoring
Continuous or point level instrumentation tied into plant control.
Why Pro Makina
Manufactured in Turkey
Design and fabrication are carried out in our own facility in Eskişehir, Turkey, with full in-house engineering control.
Project-based engineering
Every machine is sized around your raw material, moisture content and capacity target — not sold from a fixed catalogue.
Export experience
We prepare international technical proposals, shipping documentation and commissioning support for overseas projects.
Single point of responsibility
Process design, fabrication, automation and commissioning are managed by one engineering team.
Frequently Asked Questions
How large should a receiving bunker be?
It follows from your delivery logistics: truck sizes, dumping frequency and the downstream consumption rate. We size the volume so trucks never wait and the process never starves.
Which feeder goes under the bunker?
Screws for dosing accuracy, belts for high rates and mixed materials, vibro feeders for simple extraction — selected from your material and rate requirements.
