Pitman Of Oil Type Crusher Machine

• Function: The primary function is to provide the mechanical force and movement necessary for the crushing process. It is the central moving part of the crushing chamber.
• Material: Pitmans are typically manufactured from durable materials such as high-strength cast steel or cast iron to endure extreme impact, abrasion, and high stress levels over long periods of operation.
• Jaw Plate Connection: A replaceable jaw plate (manganese steel for wear resistance) is bolted or mechanically fastened to the front face of the pitman.
• Eccentric Movement: The pitman is driven by an eccentric shaft (crankshaft) and flywheels. As the eccentric shaft rotates, it causes the pitman to move in a complex elliptical or reciprocating motion, creating the crushing action.
• Lubrication: In "oil type" crushers, the bearing system (often spherical roller bearings) which supports the eccentric shaft is lubricated by a circulating oil system, ensuring smooth operation and reducing wear on critical components.
