MEKA Jaw Crushers Precision-machined, drop-forged, heat-treated Cr-SiMn-Mo SAE 4140 (42Cr, Mo4) steel eccentric shaft. The larger eccentricity of pitman shaft provides a motion that forces the material to the bottom of the jaw plate.
The ultimate primary crusher The Nordberg C Series jaw crushers are overhead eccentric single toggle jaw crushers. The feed material is crushed between fixed and movable jaw dies. Movable jaw die is mounted to the pitman. Pitman motion (kinematics) is defined by the eccentricity of the eccentric shaft and by the angle of the toggle plate.
Jaw Crushers are sized by the top opening of the crushing chamber. For example, a 32 x 54 Jaw Crusher measures 32 from jaw die to jaw die at the top opening or gape opening and 54 across the width of the two jaw dies. The narrower bottom opening of the crushing chamber is used to size the discharge material.
May 06, 2021 The jaw crusher discharge opening is the distance from the valley between corrugations on one jaw to the top of the mating corrugation on the other jaw. The crusher discharge opening governs the size of finished material produced by the crusher. Measuring Discharge Opening Measure distance at bottom of jaws at the point of the crushing cycle when the bottom of jaws is closest together.
