Single vacuum hopper loaders suitable for medium rate pneumatic conveying of low-dust pellets.
• Easy to use, no adjustment is required.
• Compact even under high conveying capacity.
• Flashing alarm lamp.
• Microprocessor based control.
• When the vacuum receiver is empty, the discharge flapper valve closes and establishes electrical contact which, in turn, starts-up automatic filter cleaning and the vacuum motor
• The vacuum in the receiver brings the discharge flapper valve back to a fully closed position and causes the suction of material into the receiver where it settles on the bottom
• The exhaust air passes through the filter, which retains dust and fine particles, and proceeds towards the pump to be discharged into the environment
• When the material reaches the volume-fill sensor, the system switches off the vacuum pump.
• The weight of material in the receiver causes the discharge flapper valve to open and the material drops into the machine hopper.
• If the receiver is not completely emptied, the material prevents the flapper valve from closing and the system goes into stand-by. A new cycle cannot be started-up until it is completely empty
