30 m³/h and 60 m³/h plants with PLC control and weight-based batching — built, installed and commissioned.
DetailsManufacturer · Cherven Bryag, Bulgaria · Since 2005
We build 30 m³/h and 60 m³/h concrete batching plants — and make the valves, wear liners, hoppers and steel structures that keep them running. Designed and fabricated in our own workshop in Bulgaria.

Capabilities
From a complete batching plant to the component that keeps it running — and parts made to your drawings as a subcontractor.

Flagship
Aggregate bins, conveyors, mixer tower, silo connections and PLC control — fabricated in Cherven Bryag and assembled on your site. Weight-based dosing keeps every batch on recipe.
Process
One team takes the job through every stage — so nothing is lost between suppliers.
You send the requirement — capacity, drawings, photos of a worn part or the site plan.
We confirm dimensions, materials and compatibility, and prepare or adapt the drawings.
Cutting, forming, welding, assembly and painting in our workshop in Cherven Bryag.
Delivery, assembly on site and connection to your existing equipment.
Testing, final acceptance and spare parts for the years that follow.

Before we begin
Tell us what you need. We reply with questions, a proposal or a quote.
Request a quoteWe manufacture batching plants with capacities of 30 m³/h and 60 m³/h. Both include PLC automation, gravimetric batching and on-site assembly and commissioning, through to final acceptance tests.
Yes. We produce 1:1 replicas of legacy valves, flanges and blades from CAD drawings, and hardfaced steel wear liners for mixers from 0.5 m³ to 3 m³.
Valve dimensions and compatibility are confirmed to specification. Send a drawing, machine details and the required actuation type.
The schedule depends on configuration, materials and site readiness. We confirm the scope and lead time after reviewing your project.
We are based in Cherven Bryag, Bulgaria. We deliver and build batching plants across Bulgaria, and ship spare parts and valves internationally.
Yes. Besides our own equipment, we manufacture metal parts and welded assemblies in batches to other manufacturers’ drawings — from first samples to recurring batches.
