BMG’s in depth energy transmission range encompasses HEKO conveyor elements, together with spherical link chains and components for submerged chain conveyors, which have been designed for reliable use in lots of harsh environments.
“High wear-resistant HEKO elements for bulk materials conveyors, that are manufactured in Germany to pristine quality standards, enhance BMG’s in depth vary of chain products,” explains Gavin Kirstein, enterprise unit manager, power transmission division, BMG. “Through the provision and support of HEKO products, BMG boosts its options service to its broad customer – base, by optimising the effectivity of bulk material conveyor systems.
HEKO elements for submerged chain conveyors to empty ash from a boiler discharge
“We recommend using submerged chain conveyors for our prospects who work with coal, wooden, refuse and scrubber sludge, to effectively acquire, cool and drain bottom ash from a boiler discharge. These conveyors, which are fitted with secure releases, are designed to handle bottom ash efficiently and safely.
“Submerged chain conveyors are sometimes put in for the transportation of slag granulated materials, ash manufactured from stone and brown coal firing, as well as metallurgical process residue or waste ash. Fluid slag or scorching ash from soften firing is crammed in a vessel with water for cooling and then transported by way of a chain conveyor from the vessel to an ash bunker.
HEKO chain strands are highly wear-resistant, case hardened and manufactured with low tolerances. Chain sprockets and chain rollers, with replaceable segments of enamel, are sealed for safe use beneath water.
HEKO’s pocket teeth chain wheels, with toothed rims, are manufactured from special alloy steels and designed for prolonged service life.
Chain contact surfaces are machined and the edges are chamfered to make sure a positive contact with the chain and a great lead into the wheel. Chain contact surfaces are hardened for long service life.
Pocket toothed chain wheels are provided to be used with special attachments – vertical shackle to DIN or TS-shackle and lift-in scraper bars. Replaceable rims have the advantage that the hub can be left in place throughout refurbishment, which saves maintenance time and reduces costs. Purchasing prices for replacements are also lower in comparison with the funding in fully new wheels. Dimensions for existing installations are tailor-made to suit every particular software.
HEKO support idling wheels and snub wheels are alternative solutions to information rails for horizontal and inclined conveyors. The use of wheels reduces friction and thus power necessities.
HEKO components for submerged chain conveyors to empty ash from a boiler discharge
HEKO chain methods with attachments could be equipped pre-assembled (with the chain as infinite spherical strands), thus eliminating the necessity for on-site assembly. Plug-in scraper attachments kind SMO, allow fast connection to endless chain strands with chain locks, making reversible conveying attainable.
Also in BMG’s vary are spherical hyperlink chains, which have been developed by HEKO for bucket elevators and chain conveyors. These elements are suitable to be used in numerous sectors, together with mining and quarrying, cement, chemical and incinerating plants, paper production, food and beverage, in addition to synthetic manure and basic machine industries.”
HEKO chains – recognized globally for high fatigue energy and close size tolerance of chain pairs – are manufactured from durable materials, together with manganese, chrome-nickel and fine grain chrome-nickel alloy steels. เกจ์ออกซิเจนsumo -controlled heat-treatment processes are employed to supply tempered or case-hardened chains.
Advantages of case-hardening embrace a excessive breaking load, resulting from a troublesome, fantastic grain core and excessive wear-resistance, from a minimum surface hardness of 800 HV. In addition to six normal hardening depths, BMG additionally provides HEKO merchandise with hardening depths to swimsuit particular requirements.
The HEKO range contains spherical steel chains, bucket and scraper attachments, chain wheels, buckets and shafts, as properly as full return and tensioning units. Heat-resistant ring kiln chains for rotary kilns additionally kind part of the range.
BMG’s nationwide branch network provides a technical advisory service on appropriate chain choice, which is a crucial think about energy transmission techniques.
