With the acceleration of urbanisation, the processing and recycling of solid waste resources such as construction debris have become pressing societal concerns. Track-mounted impact crusher plants have emerged as the preferred equipment for primary processing in solid waste recycling. Their popularity stems from key advantages such as ease of operation, flexible relocation, high cost-effectiveness, substantial output, and superior product particle shape. However, to fully leverage their production capacity and enhance economic benefits, the following points require attention during routine operation.
Points to Note
Firstly, appropriately reducing material moisture content is crucial. Excessive moisture within the material can lead to both chamber adhesion and feeding blockages. These issues will, in turn, significantly reduce the impact crusher's production capacity. Consequently, for materials with high moisture content, we should employ pre-drying methods such as sun-drying or mechanical drying. The goal is to effectively reduce moisture levels and thereby enhance the impact crusher's throughput.
Secondly, selecting an impact crusher equipped with a pre-screening conveyor belt is another significant means of boosting capacity. The presence of substantial fines in the feed material prior to crushing severely impacts the crusher's output. This occurs as the particles adhere readily, which hinders conveyance and feeding. We recommend conducting regular inspections on the equipment's fixed components, the fastenings of the impact plates, and the condition of wear parts. These inspections allow you to promptly identify and address potential issues.
Regarding equipment configuration, rationally increasing the main motor power and appropriately raising the rotor speed are also effective methods for boosting the impact crusher's output. Within the rated motor power range, a higher main motor power leads to greater production efficiency and correspondingly increased output. Simultaneously, as the rotor speed increases, both the crusher's production capacity and crushing ratio see significant improvement. However, it is important to note that speed increases must be moderate to avoid excessive power consumption and accelerated wear of the impact plates.
Moreover, the angle of the impact plate is also a significant factor affecting the output capacity of the impact crusher. While zigzag-shaped impact plates feature a simpler structure, they cannot guarantee effective impact crushing of the feed material. In contrast, curved impact plates—particularly those with an involute profile—enable the feed material to undergo vertical impact. This specific impact mechanism significantly enhances the crushing efficiency. As a result, the overall output capacity is also improved. Therefore, when purchasing and commissioning impact crushers, carefully adjust the angle of the impact plate. The goal is to ensure that the material strikes the plate perpendicularly.
Beyond equipment configuration and parameter adjustments, uniform feeding and timely replacement of wear parts are equally vital measures for boosting impact crusher productivity. Feeding must be consistent to prevent large lumps or non-crushable objects from entering the crushing chamber. Concurrently, the clearance between the impact plate and hammer plates should be regularly inspected to ensure it remains within specified limits. To maintain optimal operational condition, you should promptly replace worn components. Pay particular attention to those in direct contact with material, such as hammer plates and impact plates.
Finally, routine inspection, maintenance, and upkeep of the impact crusher are equally vital. We recommend conducting regular inspections on the equipment's fixed components, the fastenings of the impact plates, and the condition of wear parts. These inspections allow you to promptly identify and address potential issues. Furthermore, a comprehensive equipment inspection must be performed before start-up to ensure the machinery is in good working order.
