Jaw crusher appeared earlier among crushing equipments, its structure is
simple and stable. And it works reliable, the maintenance and repair is easy.
Besides, the building and construction production cost is relatively low.
Therefore, up to now jaw crusher is widely used in metallurgy, chemical
industry, building materials, electricity, traffic and many other fields.
Generally speaking, fall into two
kinds: and simple toggle jaw crusher. Jaw crusher is mainly used for coarse
crushing and mid fine crushing. Recent years, there are new types of crushers
appeared, such as new type single toggle jaw crusher, which is used for fine
crushing. And high strength jaw crusher, which is used for crushing high
strength, excessive hardness extra-low carbon FeCr. So, jaw crusher widely
applied to such industries as mining, metallurgy, building materials, highway,
railway, water conservancy, chemical industry, etc.
Functions of jaw
crusher
Jaw crusher can be used for all kinds of rocks and ore for coarse
crushing, mid fine crushing and fine crushing under compressive strength range
of 147~245Mpa. And the highest compressive strength of material is up to 320Mpa.
Jaw crusher performance features: big crushing ratio, even particle size of
finished product, simple structure, stably operation, easy to maintain and
repair and low running cost. Jaw crusher work principle: When in operation,
motor drives eccentric shaft rotating by pulley, moving close to the e-cycle and
leaving the fixed jaw. So that it realizes multiple broken methods to material,
extrusion, twist, crush. Thereby the materials gradually becoming smaller and
smaller and then fall off, finally discharge out of the discharge
port.
Operation problems and solutions
1. Why is the jaw crusher output
not able to reach the leaving factory standard?
(1) Replace or increase jaw
crusher;
(2) Change motor junction;
(3) Adjust discharge port to the
machine instruction statement. Increase fine crushing machine.
(4) Please
check if toothed plate and pitch size up to standard, if not, you shall replace
jaw plate, adjust relative position between fixed jaw plate and movable jaw
plate. Guarantee that tooth is against the root tooth. And fix them tightly to
prevent displacement;
(5) Regulate voltage higher at operation site to fit
for host motor heavy load requirement.
(6) Replace bearing or movable jaw
plate.
2. Why does the jaw plate give out jumping sound when in
operation?
(1) Please fix tight bolts;
(2) Please adjust discharge port to
guarantee gap between two jaw plates is correct.
3. The main engine geneva
wheel and movable jaw plate operate normal, but why does the machine stops
work?
(1) Replace tight spring;
(2) Replace tie rod;
(3) Reinstall or
replace bracket panel.
(5) Replace bearing.
