Importance of Rack Design to the Crusher Work Efficiency

Mining crusher refers to the crushing machinery whose row compound particles larger than three millimeters ,the content is more than 50% of the content of the total high capacity . It is Invented by British Heng. according to the size of feeding and feeding granularity, Crushing operations is often divided into rough crushing, medium crushing and fine crushing. The crusher people usually adopted are jaw crusher, impact crusher, impact crusher, compound crusher, single-stage hammer crusher, vertical crusher, gyratory crusher, cone crusher, roll crusher machine, double roll crusher, two-in-one crusher and so on.
When
people design Rack, they are often required that the centerline of the rack
center sleeve with the horizontal plane of the upper flange or horizontal plane
and spherical bearings between the verticality and the center line of the center
sleeve and shaft sleeve centerline perpendicularity is between 0.1-0.3mm. When
designing rack internal ribs, we should pay special attention that it is best
not affect the row of mines. Rack are all made of steel materials. The geometric
dimensions of the rack can reference the existing data to determine, in ensuring
the strength and stiffness conditions,we should try to reduce its weight.

When designing, we should listen to the long-term crusher users' views and
experiences on the problems should be solved in the design, so that the new
designed crusher can be improved ,innovated based on the original basis, let us
take the 2200 bottom single-cylinder Hydraulic Cone Crusher as example to
calculate the strength of the computer frame. The crusher rack test study shows
that, to produce the maximum stress position is in the vicinity of the upper and
lower frame flange.

The First is the strength calculation, we must first consider the stress of
the shelves, the crushing force is decomposed into horizontal and vertical
component.in this way, the strength can be calculated, And then calculate the
cross-section strength, finally the upper center of the sleeve strength, at
last, design the best crusher rack according to these requirements, procedures
and precautions
