Structural Features of Main Spare Parts of Impact Crusher

Impact crusher is a crushing machine that has wide application which mainly owes to its unique structure. The main spare parts of this crushing equipment include rotor, plate hammer and impacting board. Next the experts of Hongxing Machinery will give a detailed introduction to the structural features of the spare parts of impact crusher.

(1) Rotor

The structural types of the rotor of the impact crusher include whole type, combination type and welding type. The rotor of impact crusher must have enough weight in order to crush large materials. The rotor of most impact crushers adopts whole type casting steel structure so that the rotor has big rotary inertia force and is solid and durable and convenient to place the plate hammer and is able to satisfy the requirement of the crushing work. As for small-sized impact crusher, it can also uses steel plate welding structure because the manufacturing of this rotor is convenient and is easy to get balance but the strength and durability is weak.

(2) Plate hammer

The plate hammer of impact crusher is fixed on the rotor and it is an important spare part of the crusher. It requires solid installation and convenient replacement and should be made of materials that have good anti-impacting ability. The geometric shape of the plate hammer has influences on the production capacity and service life of the crushing equipment.

(3) Impacting board

The impacting board is used for sustaining the impacting force of materials that are impacted by the plate hammer and bouncing again the crushed materials back to the crushing area for crushing again. The shape and structure of the impacting board has a big impact on the crushing efficiency. In addition, the impacting board is often made of anti-impacting and anti-abrasion high manganese steel.
