Division Overview

McLanahan Corporation offers a wide range of aggregate processing equipment for washing, classifying, crushing and screening construction aggregates such as limestone, granite, sand, gravel and other similar minerals.

Around 1890, this second generation McLanahan conceived an idea to wash clay from the rock in his Florida phosphate deposits. Inside a long box, he mounted wooden logs and attached cast iron paddles to them. On January 27, 1891, he secured a patent for his new machine and called it the Log Washer.

Soon after, he realized the need for a simple crusher that could handle wet, sticky feed while reducing pieces too large for his Log Washers. In 1894, he invented the Single Roll Crusher by using a splitframe design with a crushing roll, breaking material against a solid backing plate.

S.C. McLanahan’s ideas and visions were so successful that he set the company on a new course. Thanks to the hundreds of dedicated employees who, over the years, have continually updated and modernized his designs, we now offer a wide range of equipment and systems to process raw and synthetic materials.

McLanahan aggregate processing equipment is reliable, effective and low maintenance. Complete parts and service assistance is available.
