Inpneumatic conveyingThere are several parameters that need special attention, including particle diameter, particle shape, material density, material temperature, and flowability. If the fluidity and humidity of the material are high, it is likely to cause pipeline blockage. Some powders often have abrasive properties, which can cause significant damage to pipelines.

      The biggest difficulty in conveying powders with poor fluidity is to ensure that the material enters the material pipeline at a stable rate from the feed inlet, and then discharge the powder from the material receiver again. For materials with poor fluidity and high humidity, a dedicated blowing aid and suitable filter and filter placement, as well as vacuum receiver design, should be set up to help the material reach an optimal conveying state. In any pneumatic conveying solution, the correct selection of Roots blowers and bin pumps is crucial, therefore, it may not necessarily stand out in the special discussion of special equipment required for powders with poor flowability.

       Cohesive and lightweight powders are prone to sticking and may cause blockages and bridging. A stable product flow into the material line, while for viscous materials, an appropriate solid to gas ratio is crucial. If the ratio of solid to air is too high, the pipeline will be blocked. If the ratio of solid to air is too low, it means that you are only inhaling air and not conveying too much material. The feeding device helps to feed materials into the production line at a constant speed.

How to transport materials with poor flowability in powder pneumatic conveying?

       Materials with poor flowability include zinc oxide and iron oxide, which have very poor flowability. Generally, for this type of conveying system, we use the method of transferring the material in a 50 kilogram bag to a mixing reactor. The operator places the bag into a conveyor belt, which cuts the bag open and drops the powder into a hopper. The material in the hopper is sucked from the bottom onto the conveyor line. Due to the particularly poor flowability, a specially designed stirrer with dots and a device with a vibrator are needed. With the assistance of the vibrator and stirrer, the material will be conveyed in an orderly manner.

      Lime powder has poor fluidity and is prone to moisture and clumping. In this case, we need an air heater to heat the lime powder and remove the moisture, so that it can be transported normally.The conveying devices used in different materials are different, so when choosing a pneumatic conveying system, we should choose a professional manufacturer. This not only achieves better efficiency and longer service life of the conveyed materials, but also ensures more stable machine operation,Shandong Juheng Environmental Protection Equipment Co., LtdWe have been deeply involved in the pneumatic conveying industry for 13 years and have rich experience.
