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.
Roll Crushers. Similar to Sizers, Roll Crushers can be used for the primary crushing of soft to medium hard material that can be slightly abrasive, dry, or wet and sticky. They are typically used in heavy mining applications and have a typical ratio of reduction of 4:1. Primary Roll Crushers are available in several designs:
• Electronic control of crusher discharge opening and feed rate. With adjustment of a crusher's discharge opening, as the production continues through an on-line coarse …
Manufactured sand made by roll crusher in Indonesia. The video shows the double roller crusher is turning small-sized stones into manufactured sand. There is a certain gap between the two counter-rotating rollers. Changing the gap can control the product size, shapes, and fineness modulus. Because it can produce high-fineness …

Roskamp Roll Crushers are designed for the most demanding crushing applications, with roll corrugations and roll speed differential ratios available to match any operating conditions. Available in two-, four- and six-roll designs, the 1200 Series has a 12" roll diameter and a range of 30 to 225 HP.
Single Roll Crushers. Single Roll Crushers are typically used as primary crushers that provide a crushing ratio of up to 6:1. They crush materials such as ROM coal, mine refuse, shale, slate, gypsum, bauxite, salt, soft shale, etc., while producing minimal fines.Designed with intermeshing roll teeth and a curved crushing plate, they are extremely effective in …
Crusher run is commonly used in driveways as a base material, but can also be laid on the top layer of the driveway. Is crusher run good for driveway? Crusher run (crush and run gravel) is usually used as a base layer in concrete or paved driveways and patios due to its excellent compaction and drainage properties.

The minimum product sizing of a Single Roll Crusher is generally limited to 2-3". The crushing is carried out between the full width of the extra-long curved crushing plate and the low-speed crushing roll. The curvature of …
how to desin roll crusher - Boleiro. how to desin roll crusher. Conventional singleroll crushers use a simpler toothedroll design and are commonly used to reduce coal to approximately 2–3 inch 5–8 cm topsize The capacity of the singleroll crushers is a function of the roll gap the roll length and the speed and ranges from about 30 tonsh 27 metric …
The nip angle is defined as the angle that is tangent to the roll surface at the points of contact between the rolls and the particle. It depends on the surface …
A roll crusher capacity is a measure of the amount of weight per unit time that moves through a roll crusher during operation. The theoretical maximum capacity is calculated by the equation above, but typically there are a few inefficiencies in the system that cause the true number to be 10-30% less.
In roll crushers, the material is pulled between two counter-rotating rolls which exert a shear force on it. The material breaks and reduces in size due to this force. This kind of crushing works better for materials that have a layered or flat structure because the shear forces can easily split the material along the weak planes.
How you select your primary crusher will be based on factors like moisture content, maximum rock lump size, material density SG, abrasion index, degradability and it being prone to dusting or not. The …
McLanahan Triple Roll Crushers allow producers to accomplish two stages of reduction in a single crusher. They feature a 6:1 reduction ratio in the primary stage, and a 4:1 reduction ratio in the secondary stage. This …
A rock crusher is a device used to crush rocks into smaller pieces, usually for gravel or some other road or building application. Most rock crushers have a hopper at the top -- a container which holds the …
User-friendly, high-functional Crusher Supports a wide variety of crushed particle sizes. Designed to bite objects between the two rolls and crush the objects using a built-in hybrid mechanism that crushes material by compression action and forcedly discharges the crushed product.
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.
The reduction ratio is driven by the Crusher Close Side Setting. The actual minimum safe closed side setting of a crusher will vary somewhat, for any given crushing machine, depending upon the …
The roll crusher is mainly composed of fixed roller, movable roller, machine frame, shield, protecting guard. The machine is driven by the V-belt of the motor, which makes the two …
In single-roll crushers, a piece of material is fed into the gap between a roll and a solid, stationary plate. During the operation a complex stress state is generated in the destructed material.
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.
A reduction of 3 to 1 is the average, and often it should not exceed 2 to 1; so that in actual practice it would require a 30-in. roll working in connection with the 8-ft. roll to produce the 1-in. crusher-delivery size; the first roll reducing from 10 …
