    Roll Crusher. For a given reduction ratio, single-roll crushers are capable of reducing ROM material to a product with a top size in the range of 200–18 mm in a single pass, depending upon the top size of the feed coal. Double-roll crushers consist of two rolls that rotate in opposite directions. Normally, one roll is fixed while the other

    Quad Roll Crushers. Quad Roll Crushers are ideal for producers, including those with preparation plants, who want to accomplish two stages of reduction in one pass. They can be used in coal, salt, lime, pet coke and potash operations, among others. Quad Roll Crushers are capable of achieving a 4:1 reduction ratio before feeding the crushed material

  • Single Roll Crushers McLanahan

    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. When properly fed in the direction of the roll rotation, the crushing action is carried

  • What is a Roll Crusher? (with pictures)

    2/2/2021· If the double roll crusher does not produce a fine enough material, a four-way roll crusher may be needed. In this type of machine, the pulverized material passes through the first two cylinders into a second set of cylinders located below the first. The second set of rollers crushes the material once more to achieve a finer finished product. These machines feature a relatively simple design

  • Factors to Consider When Selecting the Proper Roll Crusher

    21/11/2019· Throughput capacity of a crusher has multiple variables, which are taken into account when calculating crusher capacity. With Roll Crushers, 100% of the material flow is processed between the roll bodies or roll and crushing plate. The space created between the width of the rolls and the distance from roll-to-roll or roll-to-crushing plate must

  • The Differences Between Double Roll Crushers and

    One hundred percent of the feed to a V-belt driven Double Roll Crusher must flow between the rolls, creating a ribbon of material and increasing the potential of creating additional fines due to inter-particle crushing taking place. The feed opening spans the length of the crusher rolls but only measures to the centerlines of the roll bodies.

    24/4/2015· If a 2 inch particle is fed to the roll crusher the absolute smallest size one could expect from the crusher is 1/2 inch. Roll crushers will only crush material down to a minimum particle size of about 10 Mesh (2 mm). A roll crusher crushes using compression, with two rolls rotating about a shaft, towards the gap between the rolls 5.

  • Crushing and Screening Agg-Net

    Roll crushers Roll crushers are another form of compression crusher that can be used to crush hard and abrasive materials. They represent a medium-to-high initial investment and maintenance requirements are average. Reduction ratios are up to 3:1. This machine requires one-and-a-quarter horsepower per ton per hour of material crushed to make a 1in product. The product from the roll crusher


    Roll crushers perform better than other types of crushers when fed wet and sticky materials. (These crushers are not intended for highly abrasive material such as gravel or taconite unless presence of clay, permafrost or similar material prevents use of other crusher design). 4. Single roll crushers often require less horsepower and lower headroom in comparison to other primary reduction

  • Double Roll Crushers McLanahan

    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.

  • Coal Crushing: New-type Toothed Roll Crusher VS

    8/11/2019· To better improve the wear-resisting performance of teeth, traditional toothed roll crusher always adopts the low-alloy quenched and tempered steel as the material to make tooth of roll crushers. In general, 40 Cr is used to process the tooth. After processing, the compressive strength and the service life of tooth are improved.

    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
