10 AIR CANNONS - FEATURES AND OPTIONS AIR CANNON - BULK MATERIAL FLOW ACTIVATOR GENERAL Brelko Air Cannons are pneumatic, bulk material flow activating systems that quickly release compressed air into a storage vessel to restore flow to material that is clinging, bridging, rat holing or arching. This manual provides instructions for installing Air Cannons. APPLICATIONS Used to remove and prevent blockages and build-up of bulk material in silos, bins, hoppers, chutes etc. Resolve bulk flow problems where other methods are expensive, use more energy, damage the storage vessel, are excessively noisy and unreliable. FEATURES Unique diaphragm main valve results in extremely rapid operation and therefore more effective size for size. Only one moving part. Easy maintenance, no need to remove air cannon. Safe to operate and maintain. General Recommendations (See sketches 1, 2, 3, & 4) With chimney formation and bridging (sketches 1 & 2) Air Cannons are mounted in the vicinity of the outlet as well as in the parallel part of the silo. When arching in the bunker/silo body or building-up on the conical part occurs (sketch 3 & 4) usually blasting on one plane is sufficient, i.e. when arching in the bunker/silo just after the parallel position commences and with build-up at the top of the cone downwards along the cone wall.

11 The sketches 5, 6, 7 & 8 show further examples of blockages which can be relieved through application of Air Cannons. Sketch - 5 Sketch - 6 Sketch - 7 Sketch - 8 The approximate effective radius of an Air Cannon on the container wall as well as into bulk material is: BB003 Discharge Tube = dia 40mm Range R = ca 500mm at 6-8 bar BB005 Discharge Tube = dia 40mm Range R = ca 500mm at 6-8 bar BB010 Discharge Tube = dia 50mm Range R = ca 500mm at 6-8 bar BB025 Discharge Tube = dia 50mm Range R = ca 500mm at 6-8 bar BB050 Discharge Tube = dia 100mm Range R = ca 500mm at 6-8 bar BB100 Discharge Tube = dia 100mm Range R = ca 500mm at 6-8 bar BB200 Discharge Tube = dia 100mm Range R = ca 500mm at 6-8 bar BULK MATERIAL - A Bulk density less than T/m3 Material with low internal coefficient of friction Dry, fine material Outlet cone wall angle more than 500 Small outlet opening BULK MATERIAL - B Bulk density less than T/m3. Material that agglomerates. Coarse Material. Outlet cone wall angle more than 500. Large outlet opening. Product, Installation and Maintenance Manual - Air Cannons - Page 10 of 22

12 AIR CANNON BULK MATERIAL FLOW ACTIVATOR NOTE! Always quote silo dimensions ASSEMBLY INSTRUCTIONS Every installation differs according to the circumstances but the following points must always be considered: - 1. The discharge pipe (1, 2 & 3) must be attached to the container wall with its outlet flush with the inside surface. This is to prevent the introduction of a new obstacle, which can lead to further blockages. 2. There is a quick release valve on the lid of the Air Cannon. Its outlet must be kept free and preferably point downwards to prevent the accumulation of foreign material. An optional extra is the fitting of an exhaust silencer, which also acts as a filter. 3. Due to the mass of the Air Cannon, use should be made of a suspension chain supplied with models 25 litre (BB025) and larger. 4. The 3-way operating valve (manual or electric) should be no more than 10 metres from the Air Cannon. The vent port of the 3-way operating valve must have an orifice of at least 6mm diameter. 5. The discharge air pipe should be kept as short as possible with a minimum of bends. Difficult installations requiring long discharge pipes need to be investigated thoroughly, and could require a larger Air Cannon to be fitted to overcome discharge losses. 6. Supply air pressure should be at least 4 bar with a maximum of 8 bar. If there is a possibility of the air pressure exceeding 8 bar, then a safety relief valve must be fitted in the supply line. Also if the air supply drops below 4-bar then a booster is recommended to ensure efficient operation. Product, Installation and Maintenance Manual - Air Cannons - Page 11 of 22

13 The effective range of the Air Cannon, the size of the bunker/silo and the number and size of the outlets, together with material characteristics, determine the number and sizes of the Air Cannons required. The following two tables give a rough indication of the number of cannons in relation to the container size and material characteristics for round silos and square or rectangular bunkers. To compare round silos with square or rectangular bunkers the diameter of the silo must be multiplied by PI (3, 14) since square or rectangular bunkers are sized by perimeter length.

This is particular useful when there may be a tendency for the blocked material to consolidate, cling to the container walls and in corners and the Air Cannon blast a hole through it without moving much of the stagnant material.

Once installed (see instructions) the Air Cannon should remain pressurised even when not operating. This is to prevent the ingress of material up the discharge pipe and fouling the main diaphragm. 2. Where the Air Cannons are electrically operated, the power supply should be isolated when they are out of use or during maintenance. The air supply need only be interrupted during maintenance. 3. Frequency of firing is determined from actual conditions and should be reduced to the effective minimum to conserve air. 4. The Air Cannon should not be fired when there is no discharge from the container or if it is empty. Not only is this wasteful but it could be detrimental to the overall effectiveness of the system. 5. At least once a year the Air Cannon should be inspected and opened to check the main diaphragm condition and for internal corrosion. See maintenance instructions for correct procedure.

20 16. Maintenance Brelko air Cannons are designed to operate with minimum maintenance. With all of the parts that could possibly require attention being fitted to or under the lid of the Air Cannon, therefore it is not necessary to remove the Air Cannon for maintenance or repair. When the Air Cannon is installed a regular maintenance program should be set up. This program will ensure that the Air Cannon operates at optimal efficiency and problems can be identified and fixed before the Air Cannon stops working. All safety procedures for inspection of equipment (stationary or operating) must be observed. The Air Cannon operates in silos, bins, hoppers, chutes etc. Only visual observations can be made while the belt is running. Service tasks can be done only with the conveyor stopped and by observing the correct lockout/ Tag-out procedures. The only moving parts are: The seal in the quick-exhaust valve. The main outlet diaphragm. These parts require no lubrication but it is recommended that the air supply is fitted with an air-filter, lubricator and self draining water trap. The following steps will ensure maximum operation of the installed Air Cannon; and will greatly reduce wear and fatigue of the moving components as well as increasing the life of the Air Cannon. Frequency of these checks will depend on the plant s maintenance policy but it is recommended that it be done at least once every two weeks. Before any physical maintenance the following must be completed, failing to do so can lead to severe personal injury or even loss of life. Isolate air supply to Air Cannons and disconnect air supply pipe from quick exhaust valve. Discharge / fire Air Cannons Periodic Visual Inspection (Every 2-6 Weeks) Air Supply b. Check air supply, it should be at least 4 bar (gauge) and all supply line valves to be open. c. Check self draining water taps and ensure that they are free from any blockages and that no water build-up is present in the receiver. If so, replace water trap or remove blockage and drain water. d. Check air filters, if air filters are dirty replace or clean them. e. Listen for air filling the Air Cannon; if not, see trouble shooting below Way Valve g. The vent port should exhaust a small quantity of air; if not, repair or replace (see instructions below). h. Electric 3-Way solenoid valve should be heard to click ; if not, repair or replace (see instructions below) Quick-exhaust Valve j. Check if the quick exhaust valve on the lid vents, if not; repair or replace (see instructions below) Quarterly Maintenance Main Diaphragm b. Remove Air Cannon lid and check main diaphragm, if damaged replace (see instructions below) Discharge pipes d. Check connecting pipes, nozzles, lances etc. for excessive material build-up and blockages, if this is the case; remove and clean.
