No matter in sand production line or
stone production line, our aim is to ensure the impact crusher and jaw crusher
machine are capable of normal continuous operation. In order to extend the life
of the crusher, we must provide periodic maintenance and conservation to
crusher. So, here I’d like to remind manufacturers of idling the machines
before consignment to reduce the problems happened in the following time. New
users must fully check crushers after each shift to see if any accessories have
been loose or worn.
If you find the production capacity
cannot reach the standard set by manufacturers. The reason could be the degree
of hardness or toughness is over the limit set on the instruction; the wire of
motor is connected reversely, so that the main body runs reversely ( mobile jaw
rotates deasil.), or the triangle connection of motor is connected in the shape
of star; the discharging port is smaller than the regulation; jaw plate moves,
and tooth crest is connected with tooth crest; the voltage is too low in the
working site; the space between mobile jaw and bearing is too large because of
wearing, so that the outer circle rotates relatively.
The way to remedy those problems are
replace or increase crushers; change the connected way of motor wiring; adjust
the size of discharging port according to the instructions and increase crusher
for fine crushing; check the length between teeth plate, adjusting the relative
position between the fixed jaw plate and mobile jaw plate to make sure the
tooth crest is connected with the tooth root, and then fix clamping to prevent
displacement; increase the voltage to meet the heavy-loaded requirements of the
main body; the replace the bearings or mobile jaw.
If there is any beating or percussion during
the operation of jaw plate, the reasons could be fastening bolts are loose or
falling; the discharge opening is too small, so that the bottom of the jaws
impacts each other. To solve this problem, we must fasten or set new screws;
adjust the discharging port to guarantee suitable space between two jaw plates.
