Design Knowledge

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 design and calculation of hammer crusher STI hammerhead 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 Han economy far-reaching 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 alloy steel, some coated with Carbide appearance is low. 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. Structural design and calculation of the hammer crusher Each disc 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 nut is used 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 800 mm 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.
