Although hammer crusher is a mature mining crushing equipment, for its design, we must not sloppy. The following is the knowledge introduction to the design and calculation of crusher's hammer and disc:
◆ The hammerhead design and calculation of hammer crusher
Its design
mainly refers to the structural design. As the hammer head shape, quality,
materials are very influential to the crusher production capacity, Especially
the shape to the quality distribution, full use of the materials. As to the more
detailed discussion on the hammerhead structure design and related improvements
,you can see it in the topic. In short, hammer is the main working parts. Its
Shape, structure design have far-reaching economy effects to their work ability
, the production capacity of the entire machine. Hammerhead shape is generally
divided into light, medium and heavy these three types. This model of hammer
crusher refers to the medium-sized hammer design,and related
calculations.
The hammer crusher can also use the high manganese steel as its
design materials . Hammerhead material selection problem is a very critical
issue to improve its abrasion resistance. The choice of material depends on the
working conditions and requirements of the working parts. Because the crusher
always crush the limestone these medium hardness materials. People usually use
high carbon steel to forge or cast. adopt high manganese low alloy steel, some
is coated with appearance Carbide. Some high chromium cast iron, its wear
resistance is several times greater than the high manganese steel hammer . As to
the choice of materials: you can see the part of topic-improve wear resistance
hammerhead specialized exposition.we don't described in detail here, In short,
hammerhead choice of materials is not only related to the working life of the
hammer bit, the production capacity of the machine, production efficiency, and
is also related to various aspects of economy.
◆ Disc structural design
and calculation of the hammer crusher
Each pin requires 8 hammers. If the
disc is used suspension hammerhead,then it requires a total of nine discs,this
depends on the design requirements. Two discs on the sides, the common feature
is that one side is equipped with the locking nut, the other end is positioned
by the shaft shoulder. The used nut is GB-812-85 , so that each disc is evenly
distributed six round hole,we can use 6 pin shaft to suspend hammerhead, The
size of the disc depends on the diameter of the rotor, the size of the diameter
of the rotor is the basis of the disc design size. Therefore,we can know the
rotor diameter is 800mm according to its model, the disc size value is in a
certain range. the circular hole size is approximately equal to the hammer hole
size.
