The main cause and solution of the material blocking fault of the two-stage crusher

Pulverizer is a kind of equipment widely used in industrial production at present According to different working principles, different structural characteristics and different purposes, there are dozens of seed products in the pulverizer Among them, several two-stage pulverizers have a high market share, covering a wide range of industries It can crush coal gangue, coal cinder, shale and other materials rapidly This machine is equipped with high alloy wear-resistant hammers, which avoids the defects of the traditional crusher hammers that are not durable, and reduces a large amount of production expenditure for customers in the future production The two-stage pulverizer is a kind of equipment with excellent performance, but it does not mean that it will not fail Because of some quality problems of the equipment itself, or some artificial improper operation, it will cause failures Among them, material blockage is a common and headache failure of the two-stage pulverizer Zui So what are the main causes of the material blocking failure of the two-stage crusher? How to deal with it quickly and effectively? The main cause of the double stage crusher material blocking failure and the rapid solution 1 the main cause of the double stage crusher Zui is the fracture or aging of the hammer piece, the sealing or wear of the screen mesh, and the high water content of the crushed material Solution: the broken and severely aged hammers should be renewed regularly to keep the two-stage crusher in good working condition, and the screen should be checked regularly The moisture content of the crushed materials should be less than 14%, which can not only improve the production efficiency, but also make the two-stage crusher not blocked and enhance the reliability of the two-stage crusher 2 If the feeding speed is too fast and the load increases, the material will be blocked Solution: in the process of feeding, pay attention to the large deflection angle of the pointer of the ammeter at any time If the current exceeds the rated current, it indicates that the motor is overloaded, which will burn out for a long time In this case, immediately reduce or close the feeding door, or change the feeding mode, and control the feeding amount by increasing the feeder There are two kinds of feeders, manual and automatic The user should choose the right one according to the actual situation Because of the high speed and load of the two-stage crusher, the load fluctuation is strong Therefore, the current of the two-stage crusher is generally controlled at about 85% of the rated current 3 If the discharge pipe is not smooth or the feed is blocked too fast, the air inlet of the two-stage crusher will be blocked; if it is not matched with the conveying equipment properly, the air in the discharge pipe will be weakened or blocked when there is no air Solution: after finding out the fault, the mismatched conveying equipment shall be changed through the feeding port first, and the feeding quantity shall be adjusted to make the equipment operate normally.
