Dust extraction and collection: cyclones, hoppers, ducts — KZTM plant, Karaganda
Products — dust extraction

Dust extraction and collection from 3–10 mm steel

Cyclones, dust hoppers, flue ducts, enclosures and hoods for mining, metallurgy and cement plants. Heavy-wall design for abrasive dust — where thin galvanised sheet does not survive. Made to the customer's drawings or to our sketch.

What we make

A complete unit or individual elements — to the customer's drawings, from a sample or to our sketch. Flanged joints, drilled to your bolt pattern.
01

CN-11, CN-15, CN-24 cyclones

Single, grouped and battery type. Body, cone, outlet pipe and scroll from 3–8 mm plate.

02

Dust hoppers and collectors

Pyramidal and conical, with a spigot for a rotary valve. Shells rolled up to 25 mm.

03

Flue ducts and air ducts

Round and rectangular, DN 100–2000, 3–10 mm steel. Flanged sections, elbows, transitions, tees.

04

Conveyor enclosures and guards

Protective guards for transfer points and drives, dust enclosures over the belt.

05

Extraction hoods and local exhausts

Over crushers, screens and loading points. Sized for the design capture velocity.

06

Transfer chutes and funnels

From 6–12 mm plate, with wear-resistant liners on request.

07

Dampers, gates, expansion joints

Control and shut-off elements for ducts, fabric and metal expansion joints.

08

Support frames and platforms

Steel structures for cyclones and hoppers, access platforms, stairs.

FAQ

Frequently asked questions

Briefly about quotes, drawing formats and material. Other questions — in the FAQ block on the home page.
How do I get a cost estimate and how much does it cost?
The estimate is free. Send your drawing and a description of the task through the form on the site, via WhatsApp or to info@kztm.kz — an engineer will prepare a commercial offer with exact pricing and lead times from 24 hours on business days.
What formats do you accept drawings in?
2D drawings: DWG, DXF, PDF, as well as native CAD formats — IDW (Autodesk Inventor), CDW/FRW/SPW (KOMPAS-3D), SLDDRW (SolidWorks), DRW (CATIA). 3D models: STEP (.step, .stp), IGES (.iges, .igs), Parasolid (.x_t, .x_b), SAT (ACIS), as well as native ones — IPT/IAM (Inventor), SLDPRT/SLDASM (SolidWorks), CATPart/CATProduct (CATIA), m3d/a3d (KOMPAS-3D), PRT (NX, Creo). If you only have a paper sketch or a sample part, our design engineers will prepare the working drawing themselves.
How is your dust extraction different from ventilation ductwork?
Ventilation ducts are made from 0.5–1.5 mm galvanised sheet. Dust extraction at a concentrator or a cement plant handles abrasive dust that wears through such metal in a season. We build from 3–10 mm carbon steel, with liners on elbows and chutes. It lasts years, not months.
