Now rule the sand the most widely used devices to the number of impact crusher, sand making machine production line in plays an important role, but we all know that Sand is the loss of equipment, the need for regular maintenance and regular repair and extend the life of sand making equipment, improve work efficiency, so easy to wear impact sand What are the factors? Here for everyone to answer.
First line speed impact. Line speed is the greatest impact on operating parameters hammer wear. The reason: the size of the line speed directly affects the size of the board can hammer impact is applied to the material, size reduction ratio, and play a decisive role in product size. In addition, the line speed is too large may also cause wear plate hammer surge, it is because in the high line speeds, the material can not enter the impact zone (or enter the depth is very small), and ends with the hammer causing severe wear the. Foreign research data shows that: the board hammer wear and the line speed of a party until power is proportional to the relationship.
Second is the ability to deal with the impact of the discharge gap. Impact Sand processing capabilities also have some impact on the plate hammer wear. When processing capacity increases, product size will be thicker, crushing ratio decreases, the board hammer units along with reduced wear pure Similarly, changing the size of the discharge gap to some extent also change the thickness of granularity, so also have some influence on the board hammer wear. Has yet to be broken material properties affected. Material impact on the board to be broken hammer wear include: the nature of the material, feeding a granular size and moisture content and other factors, which influence the nature of the material to the largest number, it can be seen from the table, corresponding to different crusher machinematerials, pure wear plate hammer units vary greatly.
Impact crusher wear parts usually include board hammer, impact liner, casing liner and the rotor body protection panels. Where the board hammer wear failure shortest time, and wear and tear costs are higher, and therefore, reduce the wear plate hammer is the key to solve the impact crusher wear.
? Sand is a large equipment manufacturing operations in the process, due to long hours of work, there will be some periodic replacement of wearing parts, consumable parts used than ordinary wear and effective to reduce the replacement of wearing parts frequency, customers save investments. Sand wearing parts and maintenance details:
1, V-belt maintenance. Sand triangle belt tensioning drive size should be adjusted appropriately to ensure triangular belt force uniform, dual-motor drive, the tape should be grouped on both sides of the triangle matching, each group has its length as consistent as possible.
2, the vulnerability of repair and maintenance. Open the door shut on a regular basis to observe observe Sand internal wear, center feeding tube, cone hat, the impeller, downstream channel liner, circular guard, the degree of wear abrasion blocks worn should be replaced or repaired, wear block should also be replaced to ensure the same wear and block weight. Crusher work process opens the door to observe the inner workings of observation is strictly prohibited, to avoid danger. Impeller wear body was found in time to find a manufacturer to replace the repair.
3, the maintenance of the bearing. Sand work 2000 hours per job opening spindle bearings for cleaning, general work 7200 hours, replaced with new bearings. Upper bearing spindle assembly for swimming side, the bottom bearing is fixed end, pulled by hand after assembly pulley should be flexible rotation.
