  What is the pitman? ——The "meshing gear" of the crusher   In the fields of mining, construction, metallurgy, etc., the crusher is the core equipment for material crushing. It crushes large pieces of material into a size more suitable for processing, and the pitman is the most critical moving part of the jaw crusher. It cooperates with the fixed jaw, and through periodic reciprocating motion, it squeezes, impacts and bends the material entering the crushing chamber until the material is crushed into the required particle size.   Simply put, the pitman is like the "chin" of the crusher, and its performance directly determines the crushing efficiency, energy consumption and equipment life.   The structure of the pitman   The jaw plate of the pitman is usually cast from high manganese steel such as 18%Mn2%C, 13%Mn2%Cr, etc., and the surface is covered with a jaw plate to resist high-intensity impact and friction. The pitman assembly is made of high-quality steel castings and is driven by two large cast steel or cast iron flywheels. In addition, the forged heavy eccentric shaft and four large ball bearings of the same specifications make the Nordberg C series jaw crusher have extraordinary reliability.   The core role of the pitman: more than "crushing"   1. Determine the crushing efficiency: the swing frequency, stroke and jaw plate tooth shape of the pitman directly affect the material crushing speed and particle size uniformity;   2. Affect the life of the equipment: the selection of wear-resistant materials and structural design determine the wear resistance of the pitman under high-frequency impact;   3. Balance energy consumption and cost: efficient pitman design can reduce useless work loss and reduce long-term operation and maintenance costs.   Common problems and maintenance points of pitman   1. Common faults   - Jaw plate wear: when the material hardness is high or the feed is uneven, the jaw plate tooth tip is easy to wear, resulting in a decrease in crushing efficiency;   - Bearing damage: caused by poor bearing lubrication, the bearing lubricant needs to be replaced in time according to the cycle;   - pitman fracture: long-term overload operation or material defects may cause the pitman frame to fracture. 2. Maintenance recommendations Pre-startup inspection: 1. Check the tension of the V-belt. 2. Check the wear of the liner. If the wear limit is reached, it must be replaced immediately. 2. Check the jaw plate bolts 3. Check the tightening of the hexagonal bolt. 4. Check whether the protective rubber plate of the toggle plate is positioned and in good condition. 5. Check the tie rod nut In-operation inspection: 1. The bearing temperature is within the normal range 2. The tie rod spring is normal Daily inspection: 1. Lubricate once every 40 working hours). The required amount of grease is shown in Section 5.3.3 of the manual. 2. Lubricate the discharge port adjustment device and check the condition of its rubber cover (discharge port mechanical adjustment). 3. Check the wear of the cheek plate and replace it if necessary. 4. Check the centering, straightness and cracks of the toggle plate. 5. Check the toggle seat and rubber seal. Clean the surface of the toggle seat if necessary. 6. Check the tightening of the frame fixing bolts. 7. Check the condition of the flywheel. 8. Check the wear of the rubber shock-absorbing pad 9. Check the tightening of the frame fixing bolts on the side plate. Guide to purchasing pitman We work with technical drawings for any non-standard products.
