About Doyle Equipment Manufacturing Company


Welcome to Doyle Equipment Manufacturing Co., home of worldwide quality dry fertilizer blending, conveying, tending, and spreading equipment. Located in Quincy, IL, USA, over looking the Mississippi River, we are a four generation family owned and operated company.

Founded by the late Merle Doyle, an innovative leader in the fertilizer equipment business, Doyle Mfg. has been the leading manufacturer of bulk blenders for dry fertilizer since introducing the first rotary style drum blender in 1961.

Today, with Merle's son Ron Doyle as Chairman of the Board and grandson Monty Doyle as President, we continue to lead the way by offering top quality product with the most advanced features, service, and best warranties. The future looks bright, with great-grandson Colten Doyle looking to take the helm in years to come.



Product Overview

We manufacture a complete line of dry bulk material handling equipment for the fertilizer industry, including, but not limited to:

Rotary blend systems in 2, 5, 6, 8,10, and 13 ton capacity

Vertical auger blend systems in 6, 8, 10, 13 and 16 ton capacity

Complete line of fertilizer receiving equipment

Tending equipment, both side discharge and rear discharge, in 8, 10, 16, and 24 ton capacity

A full line of fertilizer and lime spreading equipment, starting at 2 ton capacity

We utilize the latest technology in the entire production process from initial design to the finished product. Our in house engineering team uses state-of-the-art CAD systems that ensure proper part fit, long before production ever begins. The fabrication team utilizes CNC Lasers, CNC Press Brakes, CNC Milling Machines, and CNC Lathes to produce these parts to the highest standards. Parts then move to one of our assembly areas, where the parts are put into jigs and fixtures. These jigs and fixtures ensure that each product is built consistently. Once assembled, the products move to our powder coating department. Each product is then shot blasted to remove oil, scaling, and dirt before the final powder coating process. An environmentally friendly powder coat paint booth provides a consistent finish while the bake oven cures paint at 400 degrees for durability and long life.

We are proud to say that all of our products are proudly MADE IN THE U.S.A.!
