Changzhou Chang Heng Deyu Powder Integrative Systems Ltd, the main pneumatic conveying systems, weighing and packaging equipment, transportation systems Introduction ingredient works in the feed process sump pumps conveying equipment, material is added or expanded by the double butterfly butterfly valve send in tanks, the replacement of the air through the exhaust valve to release out, making it easier to feed, but also impede the flow of material to eliminate the back pressure. When sending the tank is full (by level meter display, up to 90% of the tank volume) feed valve and the exhaust valve is closed and sealed at the same time, followed by the addition of compressed air conveying sump pumps to send the tank top via the intake valve added material mixed with compressed air, when the pressure inside the tank reaches the set value will automatically open the bottom outlet valve, then the entire transfer line Pianxiang pressure and plunger-like material in the form of transport, until the mass row empty. When sending the tank pressure falls to zero pneumatic supply namely closed, while a small amount of remaining gas is discharged also sent tanks and pipelines. Features of the system is at the beginning and end of the transfer process has a high gas flow and a higher delivery pressure, sometimes "call" at the end of the transport process indicates. Advantages simple system piping, suitable for short distances, good mobility materials. Disadvantage large gas consumption, equipment and material wear large, large displacement. Changzhou Chang Heng Deyu Powder Integrative Systems Ltd, the main pneumatic conveying systems, weighing packaging equipment, dosing delivery system Introduction 2. The critical particle size and separation of theory (1) the critical particle diameter: Strictly speaking, most of the separation process Each grade content. Cyclone diameter of the smallest particles that can be graded sump pumps conveying process, known as the critical diameter dc. The critical particle size is a reflection of the level of efficiency cyclone separation theory. Critical smaller the particle size, the higher the separation performance of the cyclone, the worse the contrary.
