Abstract

In the developed work, experiments were made with a laboratory ball mill with a liner with symmetrical displaced eight innovative lifters with a spheroidal tetrahedron type. Based on experiments done in a previous study, the number of lifters with innovative shapes, as well as their sizes, were determined. The additive material used for grinding media is PLA material and for grinding bodies PLA, SteelFill (based on PLA), and CarbonFilTM (based on PETG) are used which are printed on a 3D printer. The mill’s critical speed (CS), the angle of separation (shoulder angle), and the toe angle in the cataract mode of operation were determined experimentally. Experiments were carried out with different mill filling percentages - 20% and 30%. The required speed of the ball mill with grinding media with innovative lifters at cataract mode of operation for the three types of materials is almost the same - with an average value of 45% of CS. The best energy efficiency and grinding efficiency material at 20% filling of the mill is obtained with a SteelFill filament, and at 30% - with a PLA filament.

采用新型提升装置的球磨机磨削参数的实验确定

在开发的工作中，用实验室球磨机进行了实验，该球磨机衬板采用对称位移的八个创新的球体四面体式提升器。根据之前的一项研究的实验，确定了具有创新形状的升降机的数量以及它们的大小。用于研磨介质的添加剂材料为PLA材料，用于研磨体的PLA，使用在3D打印机上打印的SteelFill(基于PLA)和CarbonFilTM(基于PETG)。实验确定了白内障操作模式下磨机的临界转速(CS)、分离角(肩角)和磨头角。在不同的磨机填充率—20%和30%下进行了试验。对于这三种类型的材料，具有创新升降机的球磨机在白内障操作模式下的研磨介质所需的球磨机速度几乎相同-平均值为CS的45%。在填充率为20%时，使用SteelFill长丝获得了最佳的能源效率和研磨效率，而在填充率为30%时，使用PLA长丝获得了最佳的能源效率和研磨效率。

期刊介绍： WSEAS Transactions on Applied and Theoretical Mechanics publishes original research papers relating to computational and experimental mechanics. We aim to bring important work to a wide international audience and therefore only publish papers of exceptional scientific value that advance our understanding of these particular areas. The research presented must transcend the limits of case studies, while both experimental and theoretical studies are accepted. It is a multi-disciplinary journal and therefore its content mirrors the diverse interests and approaches of scholars involved with fluid-structure interaction, impact and multibody dynamics, nonlinear dynamics, structural dynamics and related areas. We also welcome scholarly contributions from officials with government agencies, international agencies, and non-governmental organizations.
