CONVENTIONAL PNEUMATIC CONVEYANCE The conventional pneumatic conveyance system relies on high pressure. In this specific case the pressure will be 2 bars. It is mainly recommended for conveying fine powders and granules, as well as fragile products like ceramic powder, over medium-short distances (15-30 metres max). It can also be used over longer distances but the efficiency (air/ product ratio) declines proportionally.

This is a non-continuous conveyance system driven by a “blow conveyor” (BART). The operating cycle begins with the opening of a “butterfly valve” located on the top part of the BART; this allows the material to start dropping into the blow conveyor. Filling stops when the “level sensor” indicates that the BART has been filled to the maximum level. At this point the “butterfly valve” will close. When these conditions have been reached, a “conveying blow valve” will open to start building up the pressure inside the BART. A “pressure sensor” will determine when the pressure (“PS1”) necessary for conveying the material has been reached inside the blow conveyor. The same pressure sensor also serves to close the air delivery line at the end of the conveyance cycle and allow the residual air to clean out the line.

The fundamental features of this conveyance system are a high air flow at the start and end of each cycle and a lower air flow during the cycle itself.

The BART pneumatic blow conveyor can convey many different kinds of materials. Both the physical characteristics of the materials and the distance they are to be conveyed have a direct influence on the machine’s performance in terms of compressed air consumption and hourly capacity.

1. It is recommended to use a compressed air storage tank with a capacity of at least 200 litres.

2. The conveyor tube, made of flexible spiral tubing or metal, must be bent into broad curves

3. The tube supplying compressed air to the pressure reducer, the pressure reducer and tube connecting the pressure reducer to the compressed air control unit must all have a diameter of 1 inch.

4. The pressure reducer must be set between 0.1 and 2 Bars

5. The maximum conveying distance is 30 metres

6. The receiving hopper must be provided with an efficient venting system to prevent the build up of counter-pressure while material is being conveyed

7. Avoid long lines with material conveyed downward

8. Use compressed air that has been dehumidified, with hygroscopic material in particular

9. The compressed air supply to the loading valve actuator and vibra-jets (where present) must be drawn upstream from the pressure reducer and must have a pressure of at least 4.5 bars to ensure that the equipment will work efficiently. The recommended value is 6 bars

STARTING UP AND OPERATION CHECK LIST

• ensure scrupulous compliance with the specifications provided in the drawings of electrical and mechanical components;

• make sure that the mechanical components have been properly installed;

• compressed air supply requirements:

o supply line section 1”

o supply line pressure 6 bars

o pressure reducer set at 0.1-2 bars

• electricity supply requirements: check the wiring and voltage;

• check the stability of the equipment;

• ambient conditions suitable for operation;

• check and/or reset the system control parameters recorded on the display;

• Be sure that the characteristics of the material to be handled are compatible with the operating conditions of the Bart60 and with the parameter settings.

• Check the correct operating of instruments on machine:

o Pressure switch

o Level indicator

o Switch and solenoid valve

• For the correct functioning of level switch, it can be required a calibration procedure, to do at the start-up of machine. See the operating instruction of instruments, attached to this manual.

BART FLUIDISATION SETTING

The BART blow conveyor builds up pressure by introducing compressed air through a feed manifold and through a fluidising filter located in the lower part of the conveyor. A gate valve allows the stream of compressed air to be divided between the fluidising filter and the feed manifold. The characteristics of the material will determine how the compressed air stream should be divided for optimal conveyance

Powder-like materials: it is recommended to direct 75% through the fluidising filter and 25% through the compressed air feed manifold.

Granular materials: a 50-50 division is recommended.

100% FLUIDISING FILTER 50% FLUIDISING FILTER 50% FEED MANIFOLD

Vessel Bart60

Pag. 16 di 36

ROUTINE MAINTENANCE 1. Check the efficiency of the bottom part fitted with the fluidising filter and replace it if necessary.

2. Check the condition of the butterfly loading valve: check for wear on the gasket and disk.

EXTRAORDINARY MAINTENANCE REPLACING THE GASKET OF THE BUTTERFLY LOADING VALVE

To replace the gasket correctly, carefully follow the directions below: First of all, make sure that the compressed air supply is DISABLEDAND DECOMPRESSED and that the power supply is OFF before performing any maintenance work.

1. remove the butterfly valve from the Bart blow conveyor and remove the actuator;

2. loosen and take out the screw situated on the side opposite the actuator;

3. screw an M6 bolt into the threaded hole to extract the spindle;

4. Remove the snap ring and extract the other spindle using suitable pliers. Now the disk is free and can be removed;

5. pry out the gasket by inserting a tool with a pointed tip and round edge, e.g. a screwdriver, between the gasket and the metal body of the valve;

WARNING:

DO NOT INSERT THE TOOL CLOSE TO THE POINT WHERE THE SHAFT PASSES THROUGH BECAUSE THIS COULD CAUSE DAMAGE TO THE SEAT DO NOT DAMAGE THE GASKET SEAT!!

6. now fit the new gasket in place, taking care to thoroughly lubricate the valve body for a smoother insertion.

7. also grease the spindles before replacing the other valve components. WARNING:

BEFORE CONNECTING THE POWER SUPPLYAND INTRODUCING COMPRESSED AIR, MAKE SURE THERE ARE NO FOREIGN BODIES IN THE DISK CLOSING AREA.

KEEPYOUR HANDS FAR AWAY FROM THE AREA INSIDE THE GASKET BECAUSE THE DISK MAY ROTATE SUDDENLY WHEN COMPRESSED AIR IS INTRO
