The Roll Crusher Transformation in Zhengzhou Hongxing Machinery

 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.

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.

3. The working condition of roller crusher should be timely checked and adjusted. The main purpose is to reduce the equipment vibration in the working process. Iron materials are strictly prohibited to enter the crushing space to prevent the equipment operation from being influenced by them.
