ESCO's Hydra Mining Division has designed and manufactured shearer drums for over 40 years and has gained a reputation around the world for problem solving when mines have particular production difficulties.

Whether it be dust, frictional ignitions, geological problems or low production rates, ESCO has designed and manufactured a range of shearer drums to combat all these problems which allows the mine operator to maximize production efficiency.

All drums are computer designed and tailor made for each longwall face to optimise the cutting performance of every installation and are constructed to withstand the demands of today's high production faces.

Unlike many other manufacturers, ESCO designs and manufactures both point attack and radial shearer drums.

ESCO's Hexbore™ cutting system is the latest addition to our point attack range of shearer drums and the new heavy duty radial riblock cutting system is helping to break production records around the world.

All shearer drums can be supplied with or without RAC (rotary air curtain) capability to dilute any methane in the cutting zone and reduce the risk of face ignitions.

In addition the cutting systems can offer ITPP (incendive temperature potential protection) to minimize both dust and the risk of frictional ignitions. As shearer drums get bigger and stronger to match the power and capability of the modern range of shearers ESCO has identified a need to design and develop a new heavy duty radial pick system to achieve the necessary pick penetration, at the higher haulage rates, without increasing dust.

SUMMARY
Today's high production longwalls need a new generation of shearer drums to reduce cost and maximise production. Hopefully this web site will appraise engineers of the alternative systems and designs available and the improvements they can achieve by examining their shearer drum design criteria.

Any longwall operator who would like to know more about the latest shearer drum designs should contact us by e-mail or by telephone detailed on our web site or call your local ESCO representative.
