Hammer crusher is mainly composed of crusher box, rotor, hammers, impact lining boards and screen plate. Among them, the main working part is the rotor with hammers. The rotor is mainly composed of principal axis, disk, pin roll and hammers. Hammer crusher has advanced structure, reliable performance, balanced working condition and low energy consumption. According to the working principle of Hammer Crusher, it can be divided into reversible hammer crusher and irreversible hammer crusher. Now let ue learn three types of hammer crusher: Large-sized hammer crusher, medium and small-sized hammer crusher. http://www.sell-ballmill.com/pro/hammer-crusher.html Because of the large impact force, the surface makes plastic deformation and it will generate a strong cold deformation strengthening, thus obtaining a high abrasion resistance, the newly exposed surface can be obtained under conditions of impact and abrasion of a new hardening layer after the surface abrasion. For small and medium-sized crusher, the feed size 200mm, hammer unit weight below 50kg, it should choose the carbon content ceiling alloy high manganese steel or medium carbon alloy steel.Without product quality assurance, it will bring a range of operation and maintenance problems. In hongxing, the production of cement production line is different, and then the size of the model chosen crusher is also different. For large crushers, the feed particle size 400 mm, and the use of hammerhead single weighing is 50-125 kg and with high toughness, so it should use ultra-high manganese alloy steel.Recently years, Hongxing are continuously innovation with its advanced technology in the crusher research and development .Its products such as impact crusher,sand maker, ball mill and jaw crusher have won a lot of repution in the industry .The heavy hammer crusher adopted advanced design concept and the first-class design process. Comparing with hammer and impact crusher,it has the advantages of bigger reduction ratio, evener crushing granularity,lower energy consumption and bigger production ability.http://www.hxjqmining.com/product3.html
