脱水屏幕

一些应用程序经历了一个 含水率低至7% 用菠菜网最稳定正规平台_最全菠菜网大全脱水筛, 但最终含水率取决于表面含水率和固有含水率. 当按重量报告水分时(kg水/kg纸浆), 固体的比重也是一个影响因素, 具有较高比重的材料显示较低的水分含量. 如果你把所有的水从颗粒之间的空隙中除去, the only water left is that which is adsorbed as a thin film on the outside surface or as inherent moisture within the material itself (some brown 煤炭s can contain up to 20% inherent moisture). 因此, 处理的材料越细，表面越不规则, 水分含量越高. Certain materials are also more hydrophobic or hydrophilic, which also affects the residual water. It is also important to underst和 that a 脱水筛’s action is critical to creating droplet formation on the underside of the bed of material. 卡尔斯鲁厄大学对这种振幅和频率的组合进行了研究, 谁提出了这一行动的建议.

在脱水筛的早期，聚氨酯销和套筒设计的介质是常见的. 从那时起, 平行发展发生了, 额定容量增加了(在某些情况下翻了一番)，并且出现了更健壮的媒体设计. 今天, pin 和 sleeve style designs are perfectly adequate 和 appropriate for sizing screen applications; however, 脱水筛上的重负荷和剧烈动作, 很少有介质制造商可以匹配应用所需的机械完整性. 菠菜网最稳定正规平台_最全菠菜网大全 spent a long time researching 和 working on designs to match the need 和 the result is a longitudinal rail style system with urethane-to-urethane connections between the media 和 the stringers -- this type of interface doesn’t fail. The frequency of replacement of media in 脱水屏幕 is such that no manufacturer or representative is going to lose much downstream revenue, 但最终用户总是受益于更好的系统.

Several factors need to be taken into consideration when designing a support structure for a 脱水筛, 包括部队, 固有频率和多单元装置. 菠菜网最稳定正规平台_最全菠菜网大全 can provide design criteria 和 assistance; call our offices for support or contact us now. 作为快速指南, 脱水屏幕 should never be underestimated in their ability to shake a structure with their mass 和 the 900 rpm 和 10 mm amplitude. Multiple 脱水筛 installations can be a challenge with harmonics; occasionally a beat will be experienced. 在某些情况下，通过地面的振动传递可以在其他结构中体验到. Good design practices include placing columns directly under the support points 和 substantial foundations to provide mass. Always allow 3” (75 mm) of clearance to other components in the direction of action (longitudinal to the screen) so no impact occurs when the vibratory motors or exciters go out of phase during shut down. Electric cables should always be supported/suspended from above directly to the junction box 和 never draped over vibrating components. 菠菜网最稳定正规平台_最全菠菜网大全’s 脱水筛 motors come with sealed junction boxes with long extended cables to connect into the electrical circuit.

菠菜网最稳定正规平台_最全菠菜网大全的工作人员率先使用甲板分隔器来允许 两种甚至三种菠菜网最稳定正规平台_最全菠菜网大全同时脱水. Producing a fine product on one side 和 a coarse product on the other with the facility to blend is part of the st和ard offering from 菠菜网最稳定正规平台_最全菠菜网大全. 工艺工程师将协助申请，以确保考虑到所有因素. Extensive out-of-balance loading (one or more of the products not being fed for long periods of time) can decrease the lifespan of the equipment.

脱水筛的最小孔径通常为50目(0.3 mm), so you will expect to see some of that size fraction 和 finer in the underflow of the screen. Not all of that fraction will pass through due to the very nature of caking style screens; fines are captured in the bed formed on top of the media. 通过屏幕的可用部分可以用几种方法处理. 最简单的方法是返回给屏幕的设备. 在流量较大的情况下，可以使用专用的清除电路.
