The distribution of particles over the cross section of the pipe is non uniform. In a dense phase flow usually the velocity of fluid is much lower than the minimum velocity required for a dilute phase flow. In this condition the material is about to choke the pipeline and if the pressure is increased these dunes and plugs of materials may move along the pipeline causing a dense phase flow. If the velocity of air is gradually lowered down below what is required to keep the particles in suspension, the particles gradually settle down and form dunes at the bottom of the pipeline all along the length of the pipe.
Other major users of pneumatic conveying systems include the chemical, plastic, water and mineral industries.Read More: Trolley Crane Design | Trolley For Material Handling | Trolley Mechanism and respectively, yeast granules, glucose, talc, paracetamol etc. The food, pharmaceutical and fine chemical industries are major users of vacuum equipment for conveying a virtually unlimited the range of products such as salt, sugar, flour, starch, spices etc. Thousands of materials, including particularly poor flowing products, are transferred regularly by vacuum conveying systems and are used by many industries for their ease of operation and efficient handling attributes. Operator at control panel of a vacuum conveyor system Option to divert exhaust air to central point through piping.Design in accordance with international standards.
#PNEUMATIC CONVEYOR FULL#
Full pneumatic system with no ignition source from electrical components. Closed system with no dust contamination. Modular program easy to modify for different requirements. Minimum maintenance since no moving parts inside the pump. 45+ years of experience conveying fragile products. Key Advantages of Spiroflow Vacuum Conveyors: In some cases, capacity and distance can be increased beyond the normal maximum ranges. Note that capacity and distance is very dependent on the properties of the conveyed material. and the conveying distances up to about 100 feet/ 30m. Our vacuum conveyors handle particle sizes from 0.5 microns, offer conveying capacity up to 10 tons/hour / 9 tonnes/hr. We evaluate, redesign (if needed) and test the application to make sure all aspects of the requirements are met. Normally a project with fragile product is executed in several steps. Spiroflow considers various technical concepts such as reducing speed in the pipeline and minimizing physical impact inside the conveyor. Conveying fragile products requires significant experience to secure the quality of the product. Our vacuum conveyors handle granules up to 50 mm. Spiroflow offers a complete range of vacuum conveyors to meet these requirements and at the same time provide high capacity with a small machine footprint. When moving powder and granules there is a great need for a solution that is hygienic, safe and prevents product damage. When particulate materials are metered into an airstream, at an optimal solids to air ratio, the differential air pressure generated via a vacuum pump creates a high enough velocity to move the materials within the conveying tube. The product is conveyed from a feed source to a delivery point suspended in a stream of gas – usually air. Vacuum conveying offers simple operation, ability to negotiate lengthy and tortuous routes and hygienic transfer of materials.
