The Importance of Rack Design to Crusher

Mining crusher is the crushing machinery whose content is more than 50% of the total content, the high capacity row compound particles are larger than three millimeters.it is invented by British Heng. according to the size of feeding and nesting granularity,Crushing operations is often divided into the rough broken in pieces and crushing. Gravel equipment 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.
The crusher is
widely used in many sectors of mining, smelting, building material, highway,
railway, water conservancy and chemical industry. The commonly used gravel
machines are jaw crusher, crusher, winnowing mill, hammer crusher, impact
crusher, roll crusher, compound crusher and so on. The jaw crusher (jaw
crusher), has a big crushing ratio, even granularity, simple structure, reliable
operation, easy maintenance, low operating cost. Side of the PF-I series of
impact crusher can process 100 to 500 mm long and the following materials, the
compressive strength of up to 350 MPa, with broken than large, the material was
broken cube particles, etc.; PF-II series impact crusher machine, which is
suitable for hard materials in the crushing, such as cement plant
limestone crushing capacity,and so on.
The crushing chamber is the most
important institutions for the crusher,its crusher cavity shape influence the
performance of the crusher cavity greatly, especially the shape of the crushing
machine. Kariba off crusher is divided into standard, medium, fine and superfine
these four kinds of cavity shape. Order to the materials and broken product
particle size accumulated content to 80% by fine-grained is showed as D and d,
crushing the ratio is D and d h . For standard and medium crushing chamber h = 4
to 6; h = 2 to 4 for fine and superfine crushing. Various specifications crusher
is equipped with a cavity (liner), as to the maximum feed size and minimum
discharge mouth wide,we don not enumerate them here. When designing, we should
listen to the users' views and experiences who are the long-term users of the
crusher on the problems ,should solve the problem addressed in the design, so
that the new design of the crusher can improved,innovated based on the original
development, let us first take the 2200 bottom of the single-cylinder
Hydraulic Cone Crusher as example,and calculate the strength of the computer
frame. The crusher rack test study shows that, the maximum stress position is
in the vicinity of the upper and lower frame flange.
The first thing need to
calculate was the shelf strength , at this time, we must first consider the
shelves' forcing conditions, the crushing force is decomposed into horizontal
and vertical component.in this way,we can calculate the cross-section strength,
and finally the upper center of the sleeve strength,according to these
requirements, procedures and precautions, we can finally design the best
crusher rack.
