Browse stationary horizontal grinders for sale from Morbark, Peterson Pacific, CBI, Diamond Z, and other manufacturers. A stationary grinder is a horizontal grinding machine installed on a permanent foundation or skid mount at a fixed location. Without the weight and cost of a transport undercarriage, a stationary grinder delivers maximum production capacity at the lowest operating cost per ton.

Why Choose a Stationary Grinder?

A stationary horizontal grinder is built for one thing: high-volume production at a fixed site. Removing the tracks, axles, and transport running gear reduces machine weight and purchase cost while freeing up horsepower for grinding. For operations that process material at a single location, a stationary setup is the most efficient configuration available.

Stationary grinders are the preferred choice for:

• Mulch production yards: high-volume grinding of clean wood into consistent mulch product for bagged or bulk sales
• Pallet recycling facilities: processing damaged and end-of-life pallets into mulch, animal bedding, biomass fuel, or ground wood fiber
• Biomass fuel plants: grinding wood waste into hog fuel or boiler fuel sized to meet power plant feed specifications
• Sawmill operations: processing slabs, offcuts, edgings, and bark into usable byproducts or fuel
• Composting facilities: primary size reduction of wood and green waste before screening or windrow composting
• C&D recycling yards: grinding sorted construction lumber and clean wood waste for recycling

Brands We Commonly See

Most major horizontal grinder manufacturers offer stationary or skid-mounted configurations. Here is what we typically see:

• Morbark: heavy-duty stationary grinders built for production-scale mulch and biomass operations. Morbark machines are a standard choice for high-volume fixed-site grinding
• Peterson Pacific: reliable grinders available in stationary configurations for yard-based wood processing operations
• CBI: some of the highest-throughput stationary grinders on the market. CBI machines are built for large-scale biomass and mulch manufacturing where daily tonnage is the priority
• Diamond Z: aggressive grinding performance in stationary and skid-mounted setups. Common at recycling yards and composting facilities

We also see Rotochopper, Bandit, and other brands from time to time. If you are looking for a specific make or model, call 770-433-2670 and we can check current availability or help locate one.

Stationary vs. Track-Mounted and Wheel-Mounted Grinders

The right configuration depends on whether your grinding operation stays in one place or moves between sites.

A stationary grinder sits on a permanent pad, concrete foundation, or skid mount. It does not move. This is the simplest, lowest-cost configuration and delivers the highest production efficiency for its horsepower rating because none of the machine weight goes toward a transport system.

A track-mounted horizontal grinder crawls across job sites under its own power. It is the right choice for land clearing, logging, and portable operations where the grinder needs to move to the material.

A wheel-mounted horizontal grinder tows behind a truck for fast highway transport. It is the right choice for grinding contractors and operations that move between prepared sites on a regular schedule.

If your material comes to you at a fixed yard or plant, a stationary grinder is almost always the most productive and cost-effective option.

What to Check on a Stationary Grinder Before You Buy

Start with the rotor and hammers. Inspect every hammer for wear, cracking, and missing tips. Check the rotor bearings for smooth rotation. Rebuilding a rotor assembly is one of the most expensive repairs on any horizontal grinder.

Next, check the engine or electric motor. Many stationary grinders run on electric power, which eliminates fuel cost and reduces maintenance. If the machine is electric, inspect the motor, drive system, and electrical connections. If it is diesel-powered, check hours, service records, and oil condition.

Inspect the feed conveyor and compression roller system for wear. These components control the feed rate and directly affect throughput and product quality.

Check the screen condition below the grinding chamber. Screens are a regular wear item and knowing the current condition tells you what your first maintenance cost will be.

Finally, evaluate the mounting system, discharge conveyor, and frame for structural wear. Stationary grinders run long hours under heavy load, which accumulates wear on structural components over time.

We help coordinate inspections so buyers can evaluate a machine before committing. Call 770-433-2670 and our team can walk you through what to look for.
