Reliable gears: the basis for continuity in the cement productionIn the cement industry gears play a crucial role within the production process.
Bierens manufactures reliable high tech gears for the cement industry that meet
the often extremely high standards.
Gears are a primary component in kiln drives, separators, crushers, screens,
gearboxes, milling facilities, fans, mills, elevators, ball mills, blowers, conveyors
and other applications.
The gears already start turning in the beginning of the production chain: the
excavation of limestone in the quarry with heavy excavators, after which the rollers
for bruising the cement clinkers are activated before the material is sent to the
cement kilns. For the calcination of cement clinker usually a rotating oven is being
used. Both a rotary kiln and a vertical shaft furnace and tunnel oven contain
moving parts whose accuracy and reliability are a requirement to ensure and
optimize the production availability. Everywhere where it should keep running, you
can rely on the gear technology and support of Bierens.
Bierens Companies consist of: Bierens Machinefabrieken B.V. in Tilburg / the Netherlands and Defawes N.V. in Ghent / Belgium.
Bierens gears for the cement industry
Bierens designs, produces, revises and reconstructs
Bierens Companies, founded in 1880, has
become the gear specialist for over 70
years. Bierens has become the unchallenged
market leader in gears, gearboxes,
mechanical drives, special machines and
overhaul work. For many years Bierens is
certified for NEN-EN-ISO 14001 and 9001
and manufactures prototypes and supplies
large and small series and products also for
the cement industry, from a custom made
gear to large crown wheels for cement kilns
or SAG mills.
Heaviest pinion ever for the cement industry
Defawes, the subsidiary of the Bierens Group
in Belgium, is an authority in the field of
unique gearboxes, high quality maintenance,
service-oriented after sales and pinion parts
supply.
Recently, Defawes has modified the heaviest
pinion ever for the cement industry (module
34, pitch diameter 1,462, weight 8,300 kg).
The quality of the final result with a
deviation of the pitch diameter of quality
DIN 2 (AGMA 15) is unequalled worldwide!
The years of experience and technical
expertise make that Defawes has become a
valued partner for the cement industry,
mining industry, steel industry, paper and
sugar factories.
GEAR TECHNOLOGY OF BIERENS
Focus on precision and quality
• Highest precision in this business through our unique 5-axis milling technique; which has proven its sustainability in the maritime world and steel industry.
• Standard quality 6 (AGMA 12) and ‘grinded’ quality 3 (AGMA 15); less wear, less heat development, less consumption.
• Certificates: NEN-EN-ISO 14001 & 9001.
• ‘State of the art’-quality control:- magnetoscopic research
- ultrasonic inspection
- x-ray research
- fully dimensional and report of
teeth measuring
Focus on markets, products and supplies
• Complete delivery program for ball mills and rotary kilns: crowns up to 10 m in diameter, running wheels, axles, spiral cones, straight gears and support wheels.
• Virtually unlimited modules (45 and more) with weights up to 16.000 kg.
• Designing and constructing of custom made gearboxes. Longest lifespan by highest quality gears.
Focus on engineering
• Own engineering services for optimizing the power transmission: new tooth forms for longer lifespan and more power transmission such as the grinded closed herringbone gear and s-gear (average 20% more power transfer than comparable cyclopaloid bevel gear).
• Grinding on site of existing crowns, combined with delivering a customized pinion for doubling of the lifespan.
• Very extensive possibilities for re-engineering: - own design
- fully digital measurement
- spectroscopic definition of the
original material specifications
• Maintenance or revision of every type and brand of gearbox.
Focus on cement industryMain applications of our products in
this industry:
• large crowns for rotary kilns and
crushing and mixing mills
• cone wheels for cone crusher
• pinions to power the mills and ovens
• gearboxes for the drive of the mixing
and crushing machines
