Double Toggle Jaw Crusher [Oil Bath Type]

Double Toggle Jaw Crusher [Oil bath type]

Double
Toggle Jaw Crushers are preferred for crushing unusually hard,
abrasive rocks and other materials like ferroalloys and glass. They
differ substantially from other types of crushers. There is no rotary
motion in the crushing cycle and all crushing is done by compression
of the feed material between two massive jaw plates. The moving jaw
compresses the material against the stationary jaw. Jaw plates can be
either smooth or corrugated.

Working
Principle and Advantages

Double
Toggle Jaw crushers have one jaw fixed, while the other jaw
pivots about the top hinge. This moving jaw is shaped to move firmly
and squarely against the material. There is no rubbing or grinding,
purely compression, which produces a generally cubical product with
minimum fines. The moving Jaw is very well balanced, so 95% of the
drive motor power is used for crushing, while only 5% of the power is
needed to move the jaw itself. As a result of this high mechanical
efficiency, Double Toggle Jaw crushers require smaller size motors,
keeping power costs down. Behind the stationary jaw are shims, used
to adjust the distance between the lower ends of the jaws (closed
side setting). This setting determines the output product size. There
is also an arrangement of safety arm for protection from uncrushables
or accidental overloads.
