  • Roll Crusher for Sale

    Crusher Feed Size and Roll Diameter. The diagram in Figure #3 shows the method used in calculating maximum feed size for any diameter of rolls; the accompanying table gives a listing of feed sizes for standard diameters. These figures are based upon zero roll spacing; therefore the distance between faces (i.e., the discharge spacing to be used) should be added to them to obtain the maximum

  • Roll Crusher an overview ScienceDirect Topics

    Roll crushers apply shear or compression to the material that is going to be reduced in size. This action occurs between two hardened surfaces. The speed and diameter of the rolls, the desired capacity, and the feed and product size distribution are all critical in

  • Coal Processing ASTEC Australia Pty Ltd

    The Double Roll Crusher is generally regarded as a 4:1 feed to product ratio crusher; however in some instances, dependent upon material friability and hardness, it is possible to achieve a 6:1 crushing ratio. The feed material should enter the centre of the gap between the two rolls and spread across the full roll width for maximum efficiency and this ensures a uniform product size

  • Dual roll crushers, how they function

    Roll crushers do, however, give a very close product size distribution, and if the ore is not too abrasive, they do not have high maintenance costs. Roll crushers have a theoretical MAXIMUM reduction ratio of 4:1. 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

  • Roll Crusher IKN

    8/10/2020· In 2004, IKN installed a 4 roll crusher for petcoke crushing at Lebec, USA. The main features of the IKN Roll Crusher are: Large pieces of clinker cannot jam the crusher. Reduced wear and dust generation due to low roller speeds . Electrical drive with low power consumption. Uniform size distribution of the crushed clinker.

    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. The particles are drawn into the gap between the rolls by

  • Shumar Crushers Minco-Tech

    Double roll crushers have proved themselves to be the most efficient type of machines in the coal industry. Use the correct crushing ratio. Crushing ratio is defined as the ratio of input size to output size. The ideal ratio is2 : 1.3 : 1 is possible but anything above that ratio causes a serious decrease in crushing efficiency. Use a crusher with the right roll diameter with respect to the
