BMG’s intensive energy transmission vary encompasses HEKO conveyor parts, together with spherical link chains and parts for submerged chain conveyors, which have been designed for dependable use in plenty of harsh environments.
“High wear-resistant HEKO parts for bulk material conveyors, that are manufactured in Germany to pristine quality standards, enhance BMG’s extensive vary of chain products,” explains Gavin Kirstein, business unit manager, energy transmission division, BMG. “Through the provision and assist of HEKO products, BMG boosts its options service to its broad customer – base, by optimising the effectivity of bulk materials conveyor techniques.
HEKO elements for submerged chain conveyors to drain ash from a boiler discharge
“We suggest using submerged chain conveyors for our clients who work with coal, wooden, refuse and scrubber sludge, to effectively collect, 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 installed for the transportation of slag granulated materials, ash made of stone and brown coal firing, as properly as metallurgical process residue or waste ash. Fluid slag or scorching ash from melt firing is crammed in a vessel with water for cooling after which 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. pressure gauge and chain rollers, with replaceable segments of tooth, are sealed for secure use underneath water.
HEKO’s pocket tooth chain wheels, with toothed rims, are manufactured from particular alloy steels and designed for extended service life.
Chain contact surfaces are machined and the edges are chamfered to make sure a optimistic contact with the chain and a great lead into the wheel. Chain contact surfaces are hardened for lengthy service life.
Pocket toothed chain wheels are provided to be used with particular attachments – vertical shackle to DIN or TS-shackle and lift-in scraper bars. Replaceable rims have the benefit that the hub may be left in place throughout refurbishment, which saves upkeep time and reduces costs. Purchasing prices for replacements are also lower in comparison with the investment in fully new wheels. Dimensions for existing installations are tailored to go well with each particular software.
HEKO help idling wheels and snub wheels are different solutions to guide rails for horizontal and inclined conveyors. The use of wheels reduces friction and thus power necessities.
HEKO parts for submerged chain conveyors to empty ash from a boiler discharge
HEKO chain techniques with attachments could be supplied pre-assembled (with the chain as endless spherical strands), thus eliminating the need for on-site assembly. Plug-in scraper attachments sort SMO, allow fast connection to countless chain strands with chain locks, making reversible conveying possible.
Also in BMG’s range are spherical link chains, which have been developed by HEKO for bucket elevators and chain conveyors. These parts are suitable to be used in varied sectors, together with mining and quarrying, cement, chemical and incinerating vegetation, paper manufacturing, meals and beverage, in addition to artificial manure and basic machine industries.”
HEKO chains – known globally for high fatigue strength and close length tolerance of chain pairs – are manufactured from durable materials, including manganese, chrome-nickel and fine grain chrome-nickel alloy steels. Advanced computer-controlled heat-treatment processes are employed to provide tempered or case-hardened chains.
Advantages of case-hardening embrace a excessive breaking load, ensuing from a troublesome, fantastic grain core and high wear-resistance, from a minimum surface hardness of 800 HV. In addition to 6 normal hardening depths, BMG additionally provides HEKO products with hardening depths to go properly with particular requirements.
The HEKO vary includes round steel chains, bucket and scraper attachments, chain wheels, buckets and shafts, as nicely as complete return and tensioning units. Heat-resistant ring kiln chains for rotary kilns also form a part of the vary.
BMG’s nationwide department network provides a technical advisory service on appropriate chain selection, which is a crucial factor in power transmission methods.
