旋转供料器可以用于粉粒的正负压输送吗

　　Can a rotary feeder be used for positive and negative pressure conveying of powder particles

　　旋转供料器是物料颗粒输送系统中负责物料传输的一环，目前大部分的气力输送设备都会用到它，那它是不是用于粉粒体的正负压输送呢？其实很多颗粒类气力输送系统正负压输送使用供料器都更加经济实惠，有些客户会觉得失重补偿供料器的准确率会比容积式供料器更高，但实际上一台与物料相匹配的容积式供料器可以具有与重量式供料器一样的性能，甚至比匹配错误的重量式供料器性能更好。在控制和检测供料器的时候，失重补偿是一种机理。如果旋转供料器无法连续地将物料从进料料斗送到输送螺杆中或皮带上，失重补偿就存在某些设计上的缺陷。每一台失重补偿供料器都应当可以采用容积的方式运行。

　　The rotary feeder is a part of the material particle conveying system responsible for material transportation. Currently, most pneumatic conveying equipment uses it. Is it used for positive and negative pressure conveying of powder particles? In fact, many particle pneumatic conveying systems use feeders for positive and negative pressure conveying, which are more cost-effective. Some customers may think that the accuracy of weight loss compensation feeders is higher than that of volumetric feeders. However, in reality, a volumetric feeder that matches the material can have the same performance as a heavy feeder, or even better performance than a mismatched weight feeder. Weight loss compensation is a mechanism used in controlling and detecting feeders. If the rotary feeder cannot continuously deliver materials from the feeding hopper to the conveyor screw or belt, there may be some design flaws in weight loss compensation. Each weight loss compensation feeder should be able to operate in a volumetric manner.

　　在评估不同的进料系统时，如果螺旋进料器和送料器，除了用失重补偿控制降低系统的不稳定性之外，为了确定其固有的精度，还应当在容积方式下检查每台供料器的准确性。侧进料式供料器比一般的固体料斗供料器多几项优势，包括耐磨结构，螺杆转矩相对较高，完全啮合的螺杆和传递扭矩的金属齿轮而不是尼龙齿轮。

　　When evaluating different feeding systems, in addition to using weight loss compensation control to reduce system instability, the accuracy of each feeder should also be checked in volumetric mode in order to determine its inherent precision for both screw feeders and feeders. Side feed feeders have several advantages over conventional solid hopper feeders, including wear-resistant structures, relatively high screw torque, fully meshed screws, and metal gears that transmit torque instead of nylon gears.

　　当料斗旋转供料器作为供纸器的进料侧，其运行三到四天就会被损坏。因此在购买设备时，如果卖家对你说他的料斗供料器可以作为侧进料供料器使用，千万不要轻易相信，而应当要求对方出具设备的性能和使用寿命的书面保证。

　　When the hopper rotates and the feeder serves as the feed side of the paper feeder, it will be damaged after running for three to four days. Therefore, when purchasing equipment, if the seller tells you that their hopper feeder can be used as a side feed feeder, do not easily believe it. Instead, you should require the other party to provide a written guarantee of the equipment's performance and service life.
