3 Madhura Handling Systems

Vacuum Conveying is the process of moving bulk dry materials, such as powders, from place to place within a factory using suction. The material is transferred in a network of tubing from the pick up point or source to the customers process. Most Vacuum Conveying System transfer product based on a timed interval to the vacuum receiver. At the end of the timed sequence the discharge valve can open and the material conveyed can discharge in to the process. 

There are two types of vacuum conveying. Dilute phase conveying and Dense phase conveying. 

• Dilute Phase Conveying the material is entrained in the air stream and the is an almost equal part of air and product. This method is excellent for conveying almost any type of powder like sugar or flour. 
• Dense Phase Vacuum Conveying the material is transferred in slugs within the convey tubing. The material moves slower then dilute phase conveying and is excellent choice for friable product or a blend of powders. 

The 3Madhura vacuum feeder uses a vacuum pump to suck the powder particles into the nozzle along with the air to form a gas stream, which passes through the suction pipe and reaches the hopper. In the hopper, gas and material separate. The separated material enters the receiving equipment. The feeding and discharging are completed by continuously opening and closing the pneumatic three-way/ two-way valve, and the opening and closing of the pneumatic valve is controlled by the control center.
The vacuum feeder is equipped with a compressed air back flushing device. Each time the material is discharged, the compressed air pulses back flushing the filter, and the powder adsorbed on the surface of the filter is dropped to ensure the normal operation of the suction. For the vacuum feeder with material level controller, the material in the receiving hopper is automatically fed through the material level controller. When the material level in the receiving hopper is higher than a certain position, the vacuum loading machine stops feeding; when the material level is lower than a certain position, the vacuum loading machine automatically begins & complete the feeding process.
