Another feature is that auxiliary crushing generally requires for some large pieces of material. In a vertical shaft impact crusher, the circumferential speed of the impeller or rotor is generally about 145 feet per second at the beginning. In some cases, it can reach as high as 330 feet per second, and even small materials can crush effectively .

The crushing action occurs when the moveable jaw is rocked against its fixed counterpart as the eccentric shaft at the top of the chamber rotates. An added benefit of jaw crushers is the reversible hydrostatic drive which makes for easy blockage clearing and easy maintenance. Jaw crushers are known for low fuel consumption comparative

From the above statement, shearing strength of the key = the torsional shear strength of the shaft. we can write from Eqn 5 and Eqn 6. l×w×τ × d/2 = (π/16)×τ1×d3. From the above equation evaluate l. l = 1.571× d × ( τ1/τ) Here if the material of the key is as same as the shaft material then τ1 = τ. then.

Axle shaft. Spindle shaft. Materials . The material used for ordinary shafts is mild steel. When high strength is required, an alloy steel such as nickel, nickel-chromium or chromium-vanadium steel is used. Shafts are generally formed by hot rolling and finished to size by cold drawing or turning and grinding. [citation needed] Standard sizes

Linear Motion Shafts with Machinable Ends. With 2" of each end softened, it''s easier to machine a custom end for mounting. The rest of the shaft is case- hardened, which increases hardness and wear resistance on the surface of the shaft while allowing the center to remain soft for absorbing stresses caused by shifting loads.
