crushers need a choke feed to utilize rock-on-rock crushing. And to main-tain a choke feed, the crusher must have the correct liner for the feed material. If coarse material is fed to a cone with a fine liner, the liner will wear unevenly near the top of the man-ganese. A feed that is too coarse will also result in low tons per hour, aWeb

As crushers must be fed constantly to avoid severe depreciation of the equipment and to maximize productivity, feed control is a vital consideration. It is of critical importance to keep a 'choke' level and to ensure that the crusher does not run empty. Users must drop 'rock onto rock', and never 'rock onto metal'.Web
