A History of Coal Mining as told by the Company Historian

Known today for its preparation plant and mineral processing equipment, nearly a century ago Jeffrey then the Joy of today, and it very well could have remained so had it not been for a disagreement between Joseph Joy and his then employer, The Jeffrey Manufacturing Company.

“In the early 1900s,” Patterson said, “Joseph Joy was working as an engineer for Joseph Jeffrey’s company, the company that had developed the industry’s first rail-mounted “face-undercutter”. A disagreement resulted in Joy leaving Jeffrey to form his own company, probably one of the most significant turning points in the history of the mining machinery industry.”

A fine grind

"This US company has developed some of the foremost biomass processing machines in the world and is ready to take on the expanding European biomass market." International Forest Industries journal - January/February 2008
"More than 60 years of experience in the business of biomass processing has industry stalwart Jeffrey Specialty Equipment perfectly positioned to take advantage of the current surge in demand for biomass machinery."

"A perfect example of the direction in which the biomass industry is headed can be seen in two recent orders filled by Jeffrey. Jeffrey has delivered machines to two massive wood pellet mills that have just been established in the US, one of which is apparently bigger than anything else previously built worldwide."

"A large European market has been evolving for some time on the back of regulations aimed at fighting global climate change which have created incentives for power companies to boost their use of renewable resources. Europe already consumes nearly 8 Mt/y of wood pellets to run factories and power plants, and to heat entire neighbourhoods."

“At the end of last summer, we decided in our down time to pursue getting a new feeder, and we looked at numerous different options,” foreman Tony Collins said. “But when we met Jeffrey [Specialty Equipment] at the Ohio Aggregates and Industrial Minerals Association show last year, we were very impressed.... the sturdiness and cost-effectiveness of their performance was very impressive, and their ability to build a feeder to work for exactly what we wanted was key.” And Jeffrey committed to an extremely quick turnaround time: after getting a commitment from J.P. Sand ten minutes before the end of the show in November, Jeffrey had the unit built and delivered by the end of December.
