Williams is an industry-leading roll crusher manufacturer and designer for high-quality roll crushers with desirable benefits such as high throughput capacity, minimal maintenance requirements, low cost per ton operation, and more. Learn more about our heavy-duty roll crushers below or contact our sales engineers to talk about your application needs.
A combination of impact, shear, and compression are the forces necessary to perform the crushing and size reduction in a Williams roll crusher. The material enters the roll crusher machine and is impacted by the roll as it rotates. Then, as the material is pulled between a crushing plate or rolls, shear and compression forces act upon the material. The rolls act as flywheels, contributing to smooth operation and efficient use of power. Roll crushing surfaces operate at a fixed distance apart, as opposed to the continually changing distances in a jaw or cone crusher. This creates a more consistent product size.Roll crushers are low in profile and relatively easy to install. They can be fed with a minimum of headroom, or even choke fed. Adjustments are simple andinternal parts are readily accessible.
Typical feed materials for Williams Roll Crushers include: bauxite, cement clinker, chalk, cinders, clay, coal, glass, gypsum, limestone, burnt lime, rock salt, sandstone, shale, sulfur ore, sea shells, and sewer sludge clinker. Single Roll Crushers, sometimes called lump breakers, can also be used for breaking frozen or agglomerated materials.
Williams Roll Crushers are used in a variety of industries such as, mining recycling, and power industries. Interested in learning more about the Williams Roll Crushers for your specific industry and application? Contact our sales engineers!
Choosing between a single roll crusher and double roll crusher depends upon the type of feed material, feed size, product size desired, and consistency of both feed and product. Both single and double roll crushers operate most efficiently with dry, friable materials. However, single roll machines have been widely and successfully used for the reduction of moist clays. They also have been long used as primary and secondary coal crushers, both at mine sites and power plants, where a minimum of fines is desired.
Williams single roll crushers reduce via a combination of impact, shear, and compression. The rolls are always toothed in patterns suited to the feed material. Single Roll Crushers generally handle larger feed sizes at higher reduction ratios in higher capacities and are particularly well suited to be used as lump breakers.
Double roll crushers reduce primarily through compression, although some shear is obtained with toothed rolls. Rolls for these crushers come in combinations of smooth, corrugated, and toothed designs. Double Roll Crushers produce a finer product at lower reduction ratios and capacities.
Oversized, heat-treated, alloy steel shafts plus self-aligning, roller-type bearings assure long life and maximum use of power. Jackshafts for control of roller speed are standard on double roll crushers, optional on larger Single Roll Crushers.
Heavy-duty compression springs permit movement of floating roll to pass tramp metal and other uncrushables, avoiding overload and damage. Smaller Single Roll Crushers are equipped with a shear pin release.
Faces Tooth patterns and corrugations to fit feed material; abrasion-resistant alloy; easily replaceable. Ash Crushers have additional features including dust-tight design and sealed cover plates for breaker plate access.
Williams Single Roll Crushers are also available in a 15 inch (381mm) diameter dust-tight version for applications such where it would be expensive to have dust collection air. Already well known for rugged construction, low profile, high reduction ratio, and economical cost, Williams Dust-Tight Ash Single Roll Crushers also have easy access to the rotor for maintenance. These dust-tight roll crushers are perfect for applications such as crushing ash, limestone, coal, or glass.

DeHart Recycling Equipment carries tough, economical scrap choppers that can reduce cumbersome waste banding and wire into recycler friendly scrap. Our fully engineered choppers are for use at loading docks, warehouses or and manufacturing floors. Just load the material (banding) into the infeed funnel. The feedworks (pinch rolls) will then grab the material and pull it into the rotating knife path. The feedworks will continue to pull until the material is consumed or the operator stops the chopper. We offer a wide range of choppers suitable for various industrial usages. Banding choppers provide increased workplace safety, reduced housekeeping costs, and convert scrap materials into increased cash flow.

These machines offer a faster payback and more value through longer life, less maintenance, and improved efficiencies to solve your wet waste problems.
Pre-crushers reduce shipping crates, barrels and other bulky items to a fraction of their original size. Each stroke of the powerful ram crushes disposed material against a tough solid steel bulkhead at the end of the charging chamber. The bulkhead automatically lifts and the crushed material is forced into the receiving container. Extremely high reduction ratios are achieved because air pockets in the material are eliminated offering substantial savings in hauling costs. Loads are easily emptied out of the receiving container because the material has lost much of its "memory."
We offer a complete line of glass crushing and pulverizing equipment, providing solutions for a variety of budgets and processing applications. Equipment choices range from a small crusher for low volume use to larger units at recycling centers to entire processing lines for restaurants and bars.
With the commingled separation system (COSS), commingled containers pass below a magnetic separator and ferrous metals are extracted. The remaining material then passes on to the breaker that reduces the glass in the stream. The material is then conveyed to a trommel screen that separates the glass from the aluminum and plastic which can then be sorted manually or through the use of a screen and an eddy current.
Choosing a system to pneumatically convey your scrap paper, cardboard or plastic is about much more than moving material from one point to another. It is about automating your plant and providing efficient by-product recovery. DeHart Recycling Equipment provides custom designed solutions that focus on reliability, operational efficiency and flexibility.
Removing atmospheric particulate from the workplace benefits both people and equipment, contributing to a cleaner work environment, reduced machine maintenance and happier, healthier employees. At DeHart Recycling Equipment, we can recommend the proper type and size collector and filtration unit for your particular application.
Dust is well known to be a lung and eye irritant, but dust poses another risk in that it can also be highly explosive. Static electricity, friction, sparks and other conditions found in the production environment are potential ignition sources for dust. Static control systems are available which are designed for the capture and control of airborne contaminants.Get in Touch with Mechanic
