• Mill (grinding) Wikipedia

    A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().

    A jaw or toggle crusher consists of a set of vertical jaws, one jaw is kept stationary and is called a fixed jaw while the other jaw called a swing jaw, moves back and forth relative to it, by a cam or pitman mechanism, acting like a class II lever or a nutcracker. The volume or cavity between the two jaws is called the crushing chamber.

  • Industrial Rock Crushers 911Metallurgist

    Industrial Rock Crushers employ two planer crushing surfaces set at a small angle to each other and convergent downward. One plane is fixed and the other is pivoted either top or bottom allowing a reciprocating motion when pushed by a pitman-toggle arrangement activated by an eccentric drive.

    EffectsPerformanceApplicationsAdvantagesRisksExampleFunctionVariationsPreparationMechanismCriticismsDetailsEtymologyConstructionDesignPhilosophyIt will be noted that the motion is a rocking one. When the swing jaw is rising, it is opening, at the top, during the first half of the stroke, and closing during the second half, whereas the bottom of the jaw is closing during the entire up-stroke. A reversal of this motion occurs during the downstroke of the eccentric.See more on 911metallurgist
