Key factors for improving the quality of dry powder balling machines

Time：Jul 03,2021

Behind every high-quality ball press machine lies an extraordinary level of dedication and hard work that most people can hardly imagine. Zhengzhou Hongxin Mining Equipment Co., Ltd. is a professional manufacturer of ball press machines, renowned for its relentless pursuit of excellence. Our core principle is to treat everyone with integrity and win customers through superior quality. After all, crafting top-tier ball press equipment requires not only premium materials but also cutting-edge technical expertise. Today, we’ll take a closer look at the dry powder ball press machine and highlight the key factors that ensure the exceptional quality of our equipment.

First of all, the dry powder briquetting machine is highly versatile, capable of efficiently compressing and shaping various powdered materials such as coal dust, mineral powder, lime powder, fluorite powder, and more. These machines come in a wide range of models, each with different power outputs, so selecting the right one depends on the customer’s desired production capacity. The gap between the press rollers and their rotational speed significantly influence the forming process. Specifically, the closer the gap between the two rollers, the greater the compression force applied to the material—but only up to a certain point. If the upper and lower rollers aren’t precisely aligned in both rows and columns during assembly, misalignment could lead to imperfect mold formation, compromising the strength of the resulting coal briquettes. Increasing the roller gap does enhance the pressing force, but it also risks causing premature detachment of the briquette before the material reaches the center. This not only weakens the final product but may also result in uneven shapes, excessive burrs, and even an inability to form briquettes altogether. To avoid these issues, it’s crucial to carefully adjust the gap between the upper and lower rollers during installation—ideally keeping it within the 2- to 3-millimeter range.

The roller shells of the dry powder ball press machine are made from 65 manganese cast steel. After undergoing a special heat treatment, their hardness can reach over 58 HRC. The roller shells feature a modular assembly design, allowing for easy replacement once worn out. Additionally, the dry powder ball press machine is equipped with a cushioning system that effectively protects the equipment from impacts caused by hard objects.
