In 1922, KIL&T built the world's largest stone crushing plant at Marblehead. It also owned many lime kilns and produced lime products. The company operated 3 ft (914 mm) gauge Shay steam locomotives to move raw stone around its quarries until World War II. KIL&T purchased 65 new Shays from the Lima Locomotive Works (Lima, Ohio) over the years.
The crushed stone materials are conveyed to crushing plant by belt conveyor for secondary crushing before they are sent to vibrating screen to be separated. After separating, qualified materials will be taken away as final products, while unqualified materials will be carried back to the stone crushing equipment for recrushing.
In the 1980s, the Company undertook a major investment to modernize the outdated Logan Quarry. A giant mobile primary crusher was designed and built—the world's largest of its kind conveyors were installed to carry rock from the primary crusher to a new wash plant and secondary crushers. [6]

The primarily used equipment in crushing are jaw crushers, gyratory crushers and cone crushers whereas rod mills and ball mills, usually closed circuited with a classifier unit, are generally employed for grinding purposes in a mineral processing plant. Crushing is a dry process whereas grinding is generally performed wet and hence is more ...
Crushed stone or angular rock is a form of construction aggregate, typically produced by mining a suitable rock deposit and breaking the removed rock down to the desired size using crushers. It is distinct from naturally occurring gravel , which is produced by natural processes of weathering and erosion and typically has a more rounded shape.
