Horizontal Grinders: Stationary and Portable

Horizontal grinders from CBI are designed and manufactured with a focus on flexibility, durability and sustainability. Whether you’re looking for a traditional portable diesel-powered horizontal grinder or a stationary electric horizontal grinder, we manufacture equipment that never compromises quality. We handle all aspects of configuring, building, installing and supporting a complete materials processing system.

Horizontal Grinders Built For Any Industry

For over 25 years, our portable and stationary grinders have delivered hours upon hours of continuous operation across countless applications. Companies primarily focusing on land clearing, bark mulch production, construction and demolition recycling (C&D) and municipal solid waste processing have regularly turned to our robust horizontal grinders. We produce both upswing and downswing grinding machines. Upswings are generally higher speed for cleaner material with premium throughput. Downswing are generally lower speed with the ability to process a more contaminated waste stream and have the flexibility to accept multiple rotor options.
