BMG’s intensive energy transmission vary encompasses HEKO conveyor components, including spherical link chains and elements for submerged chain conveyors, which have been designed for reliable use in many harsh environments.
“High wear-resistant HEKO components for bulk materials conveyors, that are manufactured in Germany to pristine high quality standards, improve BMG’s extensive vary of chain products,” explains Gavin Kirstein, enterprise unit manager, power transmission division, BMG. “Through the availability and support 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 empty ash from a boiler discharge
“We recommend the utilization of submerged chain conveyors for our prospects who work with coal, wood, 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 backside ash efficiently and safely.
“Submerged chain conveyors are often installed for the transportation of slag granulated material, ash made from stone and brown coal firing, as well as metallurgical course of residue or waste ash. Fluid slag or sizzling ash from melt firing is stuffed in a vessel with water for cooling and then transported through a chain conveyor from the vessel to an ash bunker.
HEKO chain strands are extremely wear-resistant, case hardened and manufactured with low tolerances. Chain sprockets and chain rollers, with replaceable segments of tooth, are sealed for protected use underneath water.
HEKO’s pocket tooth chain wheels, with toothed rims, are manufactured from particular alloy steels and designed for prolonged service life.
Chain contact surfaces are machined and the perimeters are chamfered to make sure a optimistic contact with the chain and an excellent lead into the wheel. Chain contact surfaces are hardened for lengthy service life.
Pocket toothed chain wheels are provided for use with particular attachments – vertical shackle to DIN or TS-shackle and lift-in scraper bars. Replaceable rims have the benefit that the hub can be left in place during refurbishment, which saves maintenance time and reduces costs. Purchasing costs for replacements are additionally decrease compared to the funding in utterly new wheels. Dimensions for existing installations are tailor-made to go properly with each specific application.
HEKO assist idling wheels and snub wheels are different solutions to guide rails for horizontal and inclined conveyors. The use of wheels reduces friction and thus energy requirements.

HEKO chain systems with attachments could be provided pre-assembled (with the chain as infinite round strands), thus eliminating the necessity for on-site assembly. Plug-in scraper attachments kind SMO, enable quick connection to endless chain strands with chain locks, making reversible conveying possible.
Also in BMG’s range are round hyperlink chains, which have been developed by HEKO for bucket elevators and chain conveyors. These parts are suitable for use in numerous sectors, including mining and quarrying, cement, chemical and incinerating plants, paper manufacturing, food and beverage, in addition to artificial manure and common machine industries.”
HEKO chains – recognized globally for top fatigue energy and close length tolerance of chain pairs – are manufactured from durable supplies, together with manganese, chrome-nickel and nice grain chrome-nickel alloy steels. Advanced computer-controlled heat-treatment processes are employed to produce tempered or case-hardened chains.
Advantages of case-hardening embrace a high breaking load, ensuing from a tough, fine grain core and high wear-resistance, from a minimum floor hardness of 800 HV. In เกจวัดแรงดันpsi to six normal hardening depths, BMG additionally offers HEKO products with hardening depths to go properly with particular requirements.
The HEKO range comprises spherical steel chains, bucket and scraper attachments, chain wheels, buckets and shafts, as nicely as complete return and tensioning models. Heat-resistant ring kiln chains for rotary kilns additionally form part of the vary.
BMG’s nationwide department community offers a technical advisory service on appropriate chain choice, which is a important think about power transmission methods.
