Hammer crusher hammer in everyday use and maintenance should pay attention to what 1) design type, proper control of feed size difference between high manganese steel hammer, non-defined maximum size beyond the design of materials maker. 2) a suitable feeding equipment, such as the use of plate feeder or feeder feeding, etc., to ensure uniform and stable feeding, avoid feeding uneven impact of the equipment and an invalid operation. 3) When the hammer casting quality error, hammerhead process should be based on current time down eyes, turn over, so that the hammer uniform wear and rotor running balance. 4) The new hammer is best weighed, divided into several groups according to the average quality, the quality requirements of each group are equal, otherwise the boot rotor imbalance likely to cause vibration. 5) To check between the hammer and the screen bars, strip and screen sieve gap between the strips, making adjustments when necessary, and change them regularly screen bar. 6) hammer crusher frame is steel material, less contact with the material, but enters the crusher inner metal liner or loss, likely to cause the hammer disc is damaged or bent, then it should be promptly replaced, otherwise it is easy to lose the hammer to cause vibration. Between 7) and the chassis side edge hammer plate materials due to the impact hammer wear plate is more serious side Zunyi City high manganese steel hammer, in order to extend the life side of the disc, the disc may be in the side and close to the side of the circumferential surface one side of the plate surfacing wear layer. 8) running friction Henan high manganese steel hammer, at both ends of the spindle shaft diameter easy to wear, when installed to the shaft diameter of the sleeve with two guard to protect the shaft diameter shaft package. 9) to timely repair of worn and withered whole. After bearing wear it should generally be based on the new size of the scraping pad, adjust shim thickness, so that it remains a reasonable gap, so as to form an effective lubricant film. Stomatal hammerhead common defects. Stomata are usually two situations: one is located in the inner and outer surfaces of different size hammer spherical bubble, characterized alone or gather together the inner wall of the hole is smooth: the other is dispersed in the hammer inside presence of small honeycomb pinholes. It is mostly concentrated in the thicker parts of the hammer, the whole surrounding pores relatively light. The reason we enumerate pores generated a bit. ①: Hammerhead casting gating system design is not correct, the molten metal vortex, entrapped gas. ②: Hammerhead bad mold exhaust gas can not escape from the mold open. ③: sand core or shell core exhaust is bad, stained with water or sand core shell core, gas is divisible. ④: When casting metal casting is uneven or interrupted flow into gas. Prevent air bubbles generated as follows. ①: improving the gating system design, such as the top note change antes antes change serpentine runner and so on. ②: clean up mold in the vent plug hammer: Increase mold exhaust passage. ③: sand core made the necessary exhaust passage. At the same time should ensure sand core, after the shell mold core and the hammer assembly of these exhaust passage with the outside atmosphere. ④: sand core characteristics should be dried high manganese steel hammer, dry sand core, shell core careful not stained with water: the casting process of metal-based coatings make up after falling paint, the paint should be noted that the moisture has completely evaporated. ⑤: without interruption even when pouring, so as not to bring gas, in order to facilitate mold exhaust, can be tilted pouring. ⑥: reasonably require strict control of the hammer and pouring temperature.
