Bulk material conveying and dosing

We offer screw and belt conveyors, hoppers and dosing stations for powders, granules and other bulk solids. Mechanical equipment is integrated with controls, inventory sensing and the receiving production process.

The whole application matters.

Material properties influence the solution as strongly as the required throughput. Design considers bulk density, particle size, moisture, abrasiveness and tendencies to stick or bridge. Routes, transfer points and buffer volumes must fit the downstream operating cycle. A simple feeder can be developed into an integrated line with defined filling, emptying and cleaning modes.

Scope of the solution

  • Screw, belt and suitable vertical conveying sections.
  • Hoppers, discharge chutes, shut-off devices and associated feeders.
  • Level sensing, weighing, drives and automatic sequences.
  • Replacement of worn components and changes to existing material routes.

From operating need to design.

01

Conveying method and construction

Screw arrangements are assessed for enclosed transfer and feeding, belt conveyors for suitable longer routes and elevators for changes in elevation. Construction materials, wear components and access openings are selected around the product, its handling behaviour and maintenance needs.

02

Storage and dosing

The hopper, outlet and feeder are designed as one station. Where a specified batch mass is required, suitable weighing and control functions are added. Screw speed alone cannot ensure constant mass delivery when bulk density or the degree of filling changes.

03

Dust, cleanability and operation

Transfer chutes, seals and extraction interfaces limit material release. The design must allow cleaning, wear inspection and blockage removal. Dust properties and area classification form inputs to equipment selection and the required protective measures for the actual installation.

Inputs that matter.

  • Product description or sample, particle size, moisture and bulk density.
  • Required flow, batch size, accuracy and cycle time.
  • Layout, elevations, raw-material supply and receiving equipment.
  • Cleaning, dust, environmental and material requirements.

Outputs and acceptance.

  • Material-flow arrangement, layout and operating modes.
  • Conveyor, hopper, instrumentation and control specifications.
  • Supply documentation and acceptance tests using the agreed product.

The actual scope and acceptance criteria depend on the application and contract.

Questions that shape the project.

Can the same screw feeder dose different products?

This depends on material properties and required accuracy. A product change may require different speed, geometry, weighing settings or cleaning arrangements.

How is capacity verified before acceptance?

We agree a representative material, input conditions and measured output. Tests also cover start-up, emptying and responses to material shortage or blockage, so that the result reflects the intended production cycle.

A clear brief.
A practical next step.

Send your drawings, operating parameters or a short description of the change you need. We will review the technical interfaces and propose the next steps towards a quotation, clarifying any missing information with you.
