Combination systems, in which a suction system is used to convey material from a number of loading points and a pressure system is employed to deliver it to a number of unloading points.Conveyors selection and operation pdf Mechanical Conveyors Selection And Operation Pdf Merge. It operates at a pressure of 6 atm and upwards. The system is ideal for conveying material from one loading point to a number of unloading points. 
Pressure-type systems, in which a positive pressure is used to push material from one point to the next. The system operated at a low pressure, which is practically 0.4–0.5 atm below atmosphere, and is utilized mainly in conveying light free flowing materials. Suction or vacuum systems, utilizing a vacuum created in the pipeline to draw the material with the surrounding air. Air compressors or blowers can be used to generate the air flow.Three systems used to generate high-velocity air stream: 
Dilute-phase systems use push-pull pressure to guide materials through various entry and exit points. Pneumatic conveyors are either carrier systems or dilute-phase systems carrier systems simply push items from one entry point to one exit point, such as the money-exchanging pneumatic tubes used at a bank drive-through window. Products are moved through tubes by air pressure. These materials are free flowing powdery materials like cement and fly ash. Every pneumatic system uses pipes or ducts called transportation lines that carry a mixture of materials and a stream of air.
