Triple Roll Crushers combine a Single Roll Crusher with a Double Roll Crusher to form a crusher that is capable of achieving a 6:1 reduction ratio in the primary stage and a 4:1 reduction in the secondary stage while producing a cubicle product at high capacity. An intermeshing tooth design means that no timing gears are required.
Offering the only Triple Roll Crusher in the mineral processing industry, McLanahan provides a crusher with a lower overall headroom requirement and a simplified process flow. The McLanahan Triple Roll Crusher also features hydraulic product size adjustment for both the primary and secondary crushing stages. This allows producers the option of changing size specifications or adjusting for wear if the need arises.
Triple Roll Crushers feature an automatic spring and toggle relief mechanism on both stages. This allows the crushing plate in the primary stage and movable roll in the secondary stage to open, safely pass uncrushable material and return to their original setting for continued operation. In addition to tramp relief, Triple Roll Crushers include access doors to assist with inspecting for wear or to facilitate roll maintenance. They are well guarded for personal protection.
Standard-Duty Triple Roll Crushers are the lightest-duty McLanahan Triple Roll Crusher and are designed to perform two-stage reduction of softer materials such as clean coal, salt, lime, trona and other materials. The drive consists of a cut tooth steel gear and pinion between the secondary stationary roll and the primary roll. In the secondary crushing section, the stationary roll drives the movable roll by means of an inter-stage V-belt drive.
Medium-Duty Triple Roll Crushers are designed to perform two-stage reduction of materials such as salt, potash, harder coals that contain medium-hard shale and slate, and other minerals, but are not suitable for hard rock and other similar materials. The drive consists of a cut tooth steel gear and pinion between the secondary stationary roll and the primary roll. In the secondary crushing section, the stationary roll drives the movable roll by means of an inter-stage V-belt drive.
Super Triple Roll Crushers are McLanahan’s heaviest-duty model of Triple Roll Crusher. Designed for high capacity ROM coal applications, they perform two-stage reduction and are capable of throughput of up to 7,000 TPH. Segmented roll shaft assemblies provide product sizing and long-lasting wear life. The Super Triple Roll Crusher is available in dual or three motor drives.
On snowy winter days throughout the United Kingdom, Ireland, Europe and even the United States, roads are being kept clear thanks to salt processed at the Irish Salt Mining & Exploration facility in Carrickfergus, Northern Ireland. READ MORE
