Turn-key plants – made to your specifications

Doubrava is one of the world’s leading providers of turn-key plants for dry building materials. Our technical know-how is based on the experience we have gained from the successful implementation of more than 1200 major projects. As a provider of the complete range of relevant products and services, we ensure both the smooth transition between project phases and the highest degree of quality.

360° expertise

More than 30 years of experience and continuous innovation – this is the basis of Doubrava’s success. As a leading technology provider, we offer our customers tailor-made solutions that cover everything from project development, engineering, manufacturing, and assembly through to commissioning and start-up.

The advantages for our customers:

Fixed prices, fixed delivery dates, short construction times, value for money, and clearly defined warranties.

Efficiency derived from experience

Some of our core competencies:

  • Innovative techniques for handling raw materials and new additives: Synthetic fibers, chemical additives, pigments, glass fibers
  • Years of experience in the storing, discharging, batching and weighing of all types of bulk materials: Titanium dioxide, wood fibers, perlite, polystyrene, chalk, cellulose fibers, color pigments, redispersible powders, microsilica, dry building materials.
  • Bespoke solutions for raw material preparation: Feeding, crushing, drying, sieving, screening, etc.
  • Expert choice of conveying technology: Vacuum and pressure conveying systems, trough screw conveyors, tube screw feeders, bucket elevators, belt conveyors, etc.
  • Detailed knowledge of mixing technology: Homogeneity, batch and continuous mixers, batch times, cycle times, plant capabilities, etc.
  • Complete range of end product handling options: Big bags, sacks, tanker trucks including truck scales, storage in silos for end products, etc.
  • Complete plants

Compact plants for dry building materials

Low investment costs for a production output of up to 15 tons per hour – Doubrava’s compact plants are ideally suited as an entry point into the production of dry building materials.

These plants are designed to be housed in an industrial shed; a movable model is also available. They can be fed with manually-batched materials, which results in a further reduction in setup costs; automatic batching can be added later. They can be used with different sizes of mixers from different producers, as required.

Technical data:

Production output:                             5-15 t/h

Overall height:                                    ≥ 6 m

Advantages

  • Low overall height thanks to horizontal design
  • Designed to be housed in a depot or factory hall
  • Numerous optional features and extras
  • Low investment costs

Available extras

  • Raw material storage silos
  • Additive and pigment batching
  • Sand dryers

Horizontal plants for dry building materials

Doubrava’s horizontal plants combine production output of up to 80 tons per hour with a particularly compact, low design. They were developed especially for use in environments with limits on permissible overall building height.

The output of these plants is between 20 and 80 t/h. In line with customer requirements, a variety of different mixers can be used (different producers and mixer sizes, residue-free and connecting dischargers).

The later addition of silos for storing raw materials is unproblematic. The particularly compact horizontal design of the horizontal plants makes it necessary to transport raw materials to and fro, as a result of which horizontal plants require more clean-up effort than vertical-build plants do.

Technical data:

Production output (1 mixer):               20-80 t/h

Overall height:                                    ≤ 18 m

Advantages

  • Low plant height as a result of horizontal design
  • Particularly suited to bulk goods not requiring frequent product changes
  • Numerous optional features and extras
  • A range of different end product handling options (silos, tanker trucks, sacks and big bags)

Available extras

  • Additional silos for storing raw materials
  • End product silos
  • Additive and pigment batching
  • Fiber Batch Feeder
  • Batching for light-weight materials (volumetric and gravimetric)
  • Sand preparation (crushing, drying, screening)
  • Central vacuuming unit

Tower plants for dry building materials

Doubrava’s tower plants are our most popular plants for dry building materials. This is due on the one hand to their high output rate of up to 100 tons per hour, and on the other hand to the ideal production conditions they create (low clean-up effort, no need intermediate transport of raw materials).

The production output of Doubrava’s tower plants equipped with one mixer is between 20 and 100 t/h. In line with customer requirements, a variety of different mixers can be used (different producers and mixer sizes, residue-free and connecting dischargers). Doubrava’s flexible modular design makes it possible to add a second mixer line at any time, which raises the output rate significantly.

Technical data:

Production output (1 mixer):               20-100 t/h

Overall height:                                    ≥ 25 m

Advantages

  • Ideal production conditions (low clean-up effort) thanks to vertical design
  • Suitable for a variety of different dry building materials
  • Numerous optional features and extras
  • A range of different end product handling options (silos, tanker trucks, sacks and big bags)

Optional extras

  • Additional silos for storing raw materials
  • End product silos
  • Additive and pigment batching
  • Fiber Batch Feeder
  • Batching for light-weight materials (volumetric and gravimetric)
  • Sand preparation (crushing, drying, screening)
  • Central vacuuming unit
