2022 Grinder Guide: Solutions Abound for Grinding and Processing Wood Waste and Scrap into Usable Products

Suppliers of grinding equipment are important partners to the pallet industry and its related industries, such as sawmills and lumber remanufacturing. Pallet manufacturers and recyclers and related businesses generate large volumes of waste wood material. They are faced with the challenge of disposing of the material or processing it into a marketable product that will help improve a company’s bottom line.

On the following pages we present information about advertisers that supply grinding equipment to the pallet industry: Astec, Bandit Industries, Boulware Equipment, Cresswood, CW Mill Equipment, Morbark, Precision Husky, Rawlings Manufacturing, Recycling Equipment, Rotochopper, and West Salem Machinery.

Choosing a grinder will depend on a number of factors related to a company’s particular application. One of the foremost questions is: what do you need to reduce? Is it hardwood or softwood? What species? Is it in the form of slabs, edgings and other residual materials from a sawmill or scragg mill? Is it trim ends from cants and lumber remanufacturing operations? Is it scrap material from recycling pallets, such as dismantling pallets to reclaim usable lumber? Do you need to grind whole scrap or junk pallets? Or do you need to reduce some combination of these materials?

The grinder for your application also will depend on the volume of material that must be reduced. How much material do you need to grind? Is the volume likely to change in the future? If so, when and by how much?

Still another consideration will be the desired end product and potential markets for the wood fiber. Will the grindings be supplied to various outlets for further processing, or do you plan to produce a finished, value-added product, such as colored mulch? What type of potential markets do you have for wood grindings? Boiler fuel? Bedding material for livestock? Mills that manufacture particle board or other wood products? Material used as a ground covering for playgrounds? Mulch? Colored mulch? Talk to potential customers in these markets and find out what their requirements are and what they pay for wood fiber.

If a company needs to grind used scrap lumber or scrap pallets from pallet recycling operations, separating nails and nail fragments likely will be an important consideration for certain markets.

If you plan to produce a finished product, such as mulch or colored mulch, will the operations require any ancillary equipment, such as screens or coloring systems?

Although the cost of the machine certainly will be a factor, so will the operating costs. Because of the tough job they do, grinders typically require regular maintenance; weigh the maintenance costs. Are you considering an electric-powered machine or one that burns diesel fuel?

What is going to be the most efficient, cost-effective way to collect or divert residual material to the grinder? A conveyor belt? A vibrating conveyor? Collecting material into hoppers and using a forklift to dump the contents into the grinder in batches?

Finally, where is your grinder going to be located, and where and how are the grindings going to be handled and stored? Will they be stockpiled on a concrete slab? Pneumatically loaded into a storage silo? Loaded directly into a waiting trailer van?

Consider the following suppliers when you evaluate your options for investing in grinding equipment.

The versatility of its line of HogZilla grinders has been demonstrated across the decades. The machines have been used in waste reduction, recycling, land clearing, and construction and demolition applications.

C.W. Mill Equipment manufactures both tub grinders and horizontal grinders, including both types of machines that are mounted on tracks to be self-propelled. Tub grinders are available as diesel-powered or electric models.

The TC series of HogZilla grinders takes its name from the torque converter drive. It allows the engine to perform at peak efficiency with multiplied torque. Because of the converter, governed speed is maintained irrespective of the load. Torque converters allow the engine to avoid lugging and needless racing while protecting the engine from shock and loads from torsion. The strength and reliability of industrial torque converters was proven decades ago in the rock crushing industry, and C.W. Mill pioneered and perfected their use in tub grinders.

The TC series of HogZilla grinders come standard with a Caterpillar C32 1,000 hp diesel engine. Other standard features include electronic horsepower controller, remote control, stacking conveyor, vulcanized conveyor belts, auxiliary hydraulic power, hydraulic rod puller, and more. Options include deflectors and restraints, rigid and swing hammer variations, mulch coloring system, fire suppression system, and more.

C.W. Mill Equipment recognized early on that the dirt and contaminants swirling around pose a potential problem for engine efficiency. To compensate for the dirt and dust in grinding operations, C.W. Mill installed the biggest possible radiator pre-cleaner. It also arranged the engine intake air duct so that it captures the cleanest and coolest air available.
