Introduction: Understanding the Difference Between Tub Grinders and Horizontal Chippers
When it comes to processing large volumes of wood, trees, and other organic material, two machines commonly used in the industry are tub grinders and horizontal chippers. Both are designed for reducing large branches, logs, and other debris into manageable sizes, but they work in distinct ways and are suitable for different types of jobs.
Choosing the right equipment can be the difference between an efficient operation and an expensive headache. In this article, we’ll explore the differences between these two powerful machines, outline their respective advantages and disadvantages, and provide tips for choosing the right one for your specific needs.
What is a Tub Grinder?
A tub grinder is a heavy-duty piece of machinery primarily used for grinding large pieces of wood, including logs, branches, and even construction debris. Tub grinders are most commonly used in the land-clearing industry, where vast amounts of material need to be processed efficiently.
These grinders are equipped with a large, rotating tub where material is fed into a set of hammermills or tub grinder rotors. The material is broken down into smaller pieces as it spins around the tub, and the finished product is discharged from the machine's side.
Advantages of Tub Grinders:
A horizontal chipper, on the other hand, is designed primarily for chipping wood into uniform-sized chips, typically for use in industries such as landscaping, paper production, or biomass fuel production. Unlike a tub grinder, a horizontal chipper processes material in a horizontal orientation, where wood is fed through the machine using a feed roller system.
Horizontal chippers are known for producing high-quality, uniform wood chips that are ideal for specific uses such as mulching or creating wood chips for biomass energy.
Advantages of Horizontal Chippers:
The choice between a tub grinder and a horizontal chipper largely depends on the material you’re processing and the end product you need. Here’s a quick guide to help you decide:
In the world of land clearing, many operators rely on tub grinders to quickly break down entire tree trunks, stumps, and branches into manageable pieces. One well-known company, Vermeer, has made a name for itself in the tub grinder market with its large, powerful machines designed for high-volume operations. Their grinders are often seen on construction sites and land clearing projects where large-scale debris processing is needed.
On the other hand, horizontal chippers are the go-to machines in applications like biomass energy production, where uniform wood chips are required for fuel. Companies like Morbark and Bandit Industries offer robust, reliable chippers that can be used in a range of industries, from landscape companies to energy producers.
Conclusion
Both tub grinders and horizontal chippers serve essential roles in the wood processing industry. By understanding their strengths and weaknesses, operators can make informed decisions about which machine best suits their needs. Whether you’re in land clearing, energy production, or landscaping, having the right tool for the job ensures efficiency, safety, and a successful operation.

What is a Tub Grinder?
A tub grinder is a heavy-duty piece of machinery primarily used for grinding large pieces of wood, including logs, branches, and even construction debris. Tub grinders are most commonly used in the land-clearing industry, where vast amounts of material need to be processed efficiently.
These grinders are equipped with a large, rotating tub where material is fed into a set of hammermills or tub grinder rotors. The material is broken down into smaller pieces as it spins around the tub, and the finished product is discharged from the machine's side.
Advantages of Tub Grinders:
- Versatile Material Handling: Tub grinders can handle a wide variety of materials, including logs, stumps, construction debris, and brush. This makes them highly versatile, especially in industries where a variety of waste materials need to be processed.
- Large Feed Capacity: The rotating tub can accept a high volume of material, making tub grinders ideal for large-scale operations that require continuous processing of bulky debris.
- Efficient Processing: With the high-speed rotation and powerful hammermill system, tub grinders are able to break down large materials into small particles, speeding up the processing time and allowing for more efficient disposal or use of materials.
- High Wear and Tear: Tub grinders often experience significant wear and tear on their parts due to the heavy-duty materials they handle. Parts such as the hammermill and screen may need frequent maintenance or replacement.
- Noise and Dust: Due to the high-speed operation, tub grinders are noisy and produce a significant amount of dust. Workers around the machine need to wear proper protective equipment, and operators must take care to ensure the machine is operating in a safe and controlled environment.
A horizontal chipper, on the other hand, is designed primarily for chipping wood into uniform-sized chips, typically for use in industries such as landscaping, paper production, or biomass fuel production. Unlike a tub grinder, a horizontal chipper processes material in a horizontal orientation, where wood is fed through the machine using a feed roller system.
Horizontal chippers are known for producing high-quality, uniform wood chips that are ideal for specific uses such as mulching or creating wood chips for biomass energy.
Advantages of Horizontal Chippers:
- Uniform Chip Size: One of the biggest advantages of a horizontal chipper is the consistent size of the chips it produces. This makes it ideal for applications that require specific chip sizes, such as paper production, energy generation, or high-end landscaping projects.
- Faster Processing of Smaller Materials: Horizontal chippers are well-suited for smaller, more consistent material, such as branches or logs with minimal knots. These machines are known for their efficiency when processing medium-sized wood into chips.
- Safer Operation: Horizontal chippers are generally quieter and produce less dust compared to tub grinders. This creates a safer and more comfortable working environment for operators and nearby workers.
- Limited to Smaller Material: Unlike tub grinders, horizontal chippers are not well-suited for large, irregularly shaped logs or material with heavy branches and roots. They are generally used for smaller, cleaner wood material.
- Lower Feed Capacity: The feed capacity of horizontal chippers is often lower than that of tub grinders. While they are fast and efficient, they may not be the best choice for processing large volumes of bulk material in a short period.
- Material Handling: Tub grinders are better suited for processing bulky, irregularly shaped materials, while horizontal chippers excel in producing uniform chips from cleaner, smaller logs or branches.
- Output Quality: Tub grinders produce a range of particle sizes, including larger chips and mulch, while horizontal chippers produce consistent, small-sized chips that are ideal for applications requiring specific chip sizes.
- Throughput Capacity: Tub grinders are typically more suitable for high-volume operations, while horizontal chippers are better for smaller to medium-sized operations where the focus is on chip consistency and quality.
- Maintenance: Tub grinders often require more maintenance due to the heavy-duty material they process, while horizontal chippers tend to have fewer wear-related issues, especially when handling smaller materials.
The choice between a tub grinder and a horizontal chipper largely depends on the material you’re processing and the end product you need. Here’s a quick guide to help you decide:
- For Land Clearing or Bulk Waste Processing: If you're handling large volumes of tree debris, construction waste, or other bulky materials, a tub grinder is likely your best choice. It can handle irregular materials and provides fast, efficient processing.
- For Wood Chips and Specific Applications: If your goal is to produce high-quality, uniform wood chips for use in biomass energy production, landscaping, or paper production, a horizontal chipper will be more suitable. Its ability to produce uniform chip sizes is invaluable in these industries.
