摘要

目的。目前的研究重点是实验研究各种参数对Al-Balqa应用大学开发和实施的振动颚式破碎机产生的粒度的影响。主要目的是找到所研究颚式破碎机的最佳工作条件。方法。颚式破碎机的角度和旋转质量类型被认为是研究在三种不同的电机运行速度:1500rpm, 2000rpm和2500rpm下获得的所有颗粒尺寸和还原比。重900克26毫米粒度的粗骨料被送入颚式破碎机,它产生几种粒度(19、12.5、9.5、4.75和小于4.75毫米)。此外,还测量了颗粒的质量,并计算了颗粒的尺寸缩减。发现。研究发现,颚式破碎机的角度、旋转质量类型和电机运行速度对减少质量量和减小所产生的每个颗粒的尺寸都起着重要作用。此外,已经确定,在2000转/分钟的速度下操作,所考虑的每种粒度的质量和尺寸减小都有显著变化。创意。本研究的独创性在于实验研究了振动颚式破碎机中各种参数对粒度减小的影响,并引入了一种新的设计,即使用一台电机驱动两个以不同速度和相反方向运行的板。实际意义。研究结果可用于优化各种行业颚式破碎机的设计和运行,包括冶金、采石场和采矿行业,这些破碎机在这些行业中得到广泛应用。本研究的结果也可以作为未来研究其他类型破碎机和磨粉设备的粒度降低的基础。

Investigation of vibrating jaw crusher experimental variables
Purpose. Current research focuses on studying experimentally various parameters affecting the particle size produced in a vibrating jaw crusher developed and implemented at Al-Balqa Applied University. The main purpose is to find the optimal conditions at which the jaw crusher under study works. Methods. The jaw crusher angle and rotating mass type are considered to study all particle sizes and reduction ratios obtained for three different motor operation speeds: 1500, 2000, and 2500 rpm. Coarse aggregate weighing 900 g with 26 mm particle size is fed into the jaw crusher, which produces several particle sizes (19, 12.5, 9.5, 4.75, and less than 4.75 mm). Furthermore, the mass of the particles is measured and the particle size reduction is calculated. Findings. It has been found that the jaw crusher angle, rotating mass type, and the motor operation speed play an important role in both reducing the amount of mass and reducing the size of each particle produced. In addition, it has been determined that operation at a speed of 2000 rpm provides a significant change in both mass and size reduction of each particle size considered. Originality. The originality of this research lies in its experimental investigation of the effects of various parameters on particle size reduction in a vibrating jaw crusher, as well as in the introduction of a new design that uses one motor to drive two plates operating at different speeds and in opposite directions. Practical implications. The findings can be used to optimize the design and operation of jaw crushers in various industries, including metallurgical, quarry, and mining industries, where these crushers are widely used. The results of this study can also serve as a basis for future research on particle size reduction in other types of crushers and milling equipment.
