Roll Crusher Applications
These machines can handle a wide range of materials, including:
- Bauxite
- cement clinker
- chalk
- cinders
- clay
- coal
- glass
- gypsum
- limestone
- burnt lime
- rock salt
- sandstone

Single vs. Double Crushers
Choosing between a single crusher and a double crusher depends upon several factors. These include 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, the successful use of single-roll machines to reduce moist clays has occurred. Double crushers are successful for both primary and secondary crushing when minimizing fines.
Single Roll Crushers
These machines reduce via impact, shear, and compression. The rolls provide toothed patterns suited to the feed material. Single Roll Crushers generally handle larger feed sizes at higher reduction ratios in higher capacities. These machines are also great as lump breakers.
Double Roll Crushers
Double roll crushers reduce primarily through compression, although toothed rolls provide some shear. Rolls come in smooth, corrugated, and toothed designs. Double Roll Crushers produce a finer product at lower reduction ratios and capacities.
Williams Crusher Features
Heavy-Duty Drive Shafts & Bearings
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 and optional on larger Single Roll Crushers.
Protective Spring Releases
Heavy-duty compression springs allow the floating roll to pass tramp metal and other uncrushable materials. This feature helps the machine avoid overload and damage.
Simple Roll Adjustment
Quickly set and maintained via manual bolt/shim arrangement. Shrink loads occur in compression rather than tension.
Choice of Drives
Multiple V-belt drives provide maximum shock absorption. Shaft-mounted speed reducers are optional.
Easy Accessibility
Housings for single crushers split and open at the centerline to access all working parts. Double Roll Crushers models dismantle easily.
Low Peripheral Speed
Combined with compression-type reduction, it results in less maintenance when crushing abrasive materials.
Welded Steel Frame
Heavy rolled plate and welded structural shapes for rigidity and resistance to shock.
Reversible, Replaceable Liners
Machine liners offer protection for internal surfaces and frames. Thick, abrasion-resistant alloys are reversible for added life and easily replaced.
Custom-Engineered Replaceable Roll Faces
Faces Tooth patterns and grooves to fit feed material; abrasion-resistant alloy; easily replaceable.
Ash Crushers have additional features, including a dust-tight design and sealed cover plates for breaker plate access.
Ash Single Crusher
Williams’ Single Crushers are also available in a 15-inch (381mm) diameter dust-tight version.
These are 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 crushing ash, limestone, coal, or glass applications.
