Eli Whitney Blake invented the first successful mechanical rock breaker, the Blake jaw crusher patented in 1858. Blake adopted a mechanical principle familiar to all students of mechanics, the powerful toggle linkage.
roll with constant stroke in the entire crusher cavity allows for higher reduction ratio and more effective use of crushing energy. Under load, the freely rotatable roll slowly turns backwards which distributes the loads over the entire roll circumference and ensures uniform wear and maximized lifetime of the roll liners.

Versatile – The Double Roll Crusher crushes a wide range of material types reaching compressive strengths of up to 150 MPa and higher. It is less sensitive to wet and sticky material than RollSizers and can take in larger feed sizes, making it the optimal primary crusher for soft and medium hard rocks. ...
How Single Roll Crushers Work. A Single Roll Crusher is made up of a toothed roll assembly, which crushes the incoming feed material against a crushing plate. The Single Roll Crusher is designed to reduce larger feed sizes to the desired product size at a 6:1 ratio of reduction while producing a considerably lower percentage of fines.
Double Roll Crushers. Double Roll Crushers typically follow a primary or secondary crusher and are used for secondary and tertiary reduction of various minerals, such as ROM coal, clean coal, limestone, gypsum, trona, shale, bauxite, oil shale, coke, salt, lime, glass, kaolin, brick, shale and wet, sticky feeds.
Due to the low crushing ration, the thyssenkrupp Polysius Double-Roll-Crusher is producing a product size ditribution with less content of fines and therefore it is the most suitable machine for the lime-industrie. Contact. thyssenkrupp …
Mode of Operation. The material is crushed by shear- and tensile forces generated by high rotor torques at a low circumferential speed. Due to the arrangement of the crushing tools the fines in the feed can pass through the crushing rolls similar to a roller screen without being crushed.
Roll crusher is used for bulk material handling in industries. Smooth Two Roll Crusher is used for medium and fine crushing of soft to medium hard material like coal, fertilizer, chalk, limestone etc. Single Roll Crusher is an ideal primary breaker for ROM coal, soft to hard lime stone, ores etc.
Inventor Eli Whitney Blake is credited with designing the first mechanical rock crusher that was actually put to use. Blake's design, which utilized a toggle linkage construction, was known as the Blake Jaw Crusher. …

Typically used as secondary or tertiary crushers, McLanahan Double Roll Crushers provide a 4:1 reduction ratio and can be used following other McLanahan equipment, such as Feeder-Breakers, Rotary Breakers, primary DDC-Sizers, or Single Roll Crushers, when further reduction of primary crushed material is required.
Download the Roll Crushers Troubleshooting Guide. McLanahan Corporation's Roll Crusher Troubleshooting Guide can help you solve such situations as the machine fails to start, the electric motor is operating, but the roll(s) not rotating and more.
While jaw crushers provide excellent primary crushing duties, new ways of crushing needed to be devised for finer and more consistently sized aggregates. In 1920, the brothers …
How Quad Roll Crushers Work. Quad Roll crushers are designed for larger feed sizes and high ratios of reduction at high capacities. The top stage of the Quad Roll crusher is essentially made up of a double roll crusher, which is designed …
And the most common one is double-roll crusher. According to the surface of rolls, it can be divided into smooth roll crusher and toothed roll crusher. (The following roll crusher refers to "smooth roll crusher".) Applications of roll crushers Roll crusher is applied more widely than other crushers because of its small volume and cheap price.
When larger feed sizes require up to a 6:1 ratio of reduction to achieve the final product, a Triple Roll Crusher should be chosen due to the inherent design, which allows the larger feed sizes to be readily grabbed in the …
Before we discover all the different types of crushers, we need to know what a crusher is and what it is used for.
