Transformation Improves Quality of Roll Crusher
The roll crusher is suitable for medium and fine crushing of materials with medium hardness, such as the limestone, slag, coke and coal, which are used in cement, chemical industry, electric power, metallurgy, building materials, refractory materials and other industry departments. Roller crusher mainly consists of roller, roll wheel support bearing, pressure and adjusting device and actuating device.
In order to prolong the service life of roller crusher, Henan Hongxing Machinery researches and transforms the machine.
The factors affecting the service life of roller crusher are as follows:
1. In the working process of roller crusher, the entrance of iron sundries will bring about the strenuous motion of roller crusher and increase the wear strength of components and parts. When the granularity of to-be-crushed material is extremely large, it will have effects on its service life on account of serious abrasion.
2. In the process of maintenance and repair welding for roller crusher, the uneven repair welding to roll surface leads to uneven force due to the repair welding technology or other reasons. Or due to the poor quality of wear resistant welding rod, delamination or flaw phenomenon may occur because wear resistant welding rod cannot be well combined with the roller surface wood. The extremely low temperature of roll surface or halfway clean to roll surface in repair welding process will lead to the occurring of slag inclusion and interlayer phenomenon. The factors described above can lead to the short service life of roller crusher. To a service-oriented brand integrity,As the professional manufacturer of complete sets of mining machinery, like spiral separator, Henan Hongxing is always doing the best in products and service.primary jaw crusher:http://www.hxjq-mill.com/products/jaw_crusher.html
The unreasonable thickness adjustment of roll BITE underboarding causes the large pressure fluctuation and great vibration in the equipment operation and shortens the service life of roll.
The transformation of Hongxing Machinery to roller crusher:
1. Elaborate selection of the material used in the equipment production. Through multiple experiments, Hongxing roller crusher adopts specialized abrasion resistant welding wire, which has the advantages of good crack resistance performance, high stress resistance to wear and high capacity of bearing drastic vibration wear.
2. Strict norm to roll welding technique. Weld technician must undergo the professional training to master the welding technique. Moreover, before welding, roll surface must be cleaned up to reduce the occurrence of slag inclusion and interlayer phenomenon. During the process of welding, the diameter and circular degree of roll should be generally checked to guaranty the concentricity of roll surface.
Reasonable maintenance and correct operation of roller crusher can ensure long-term and continuous work and reduce stop time. Only when normal management and checking the normal work of the roll crusher every day, can the stoppage be prevented to ensure the roller crusher work continuously.
