Installation & Training Included Power Requirements Standard Power Voltage is 460 volts 3-phase at 60 Hz. Customer must specify when a different voltage is required. MACHINE CONSTRUCTION The machine consists of the following elements: entrance vestibule, blast cabinet, exit vestibule. Entrance Vestibule The entrance vestibule is the first section of the machine and it is constructed with several layers of abrasion resistant rubber curtains to prevent abrasive escaping from the machine. These curtains also isolate the blast cabinet dust and noise emission. The entrance vestibule is under-pressure and ventilated by the dust collector Blast Cabinet The blast cabinet is a welded construction made of 5/16” thick manganese steel and additionally lined inside with protective HARDOX and manganese steel plates of thickness from 5/32” to 5/16”. The side wall of the cabinet area is constructed with a service access door complete with a limit switch. Internally, all the blast cabinet walls are made of 2 layers of abrasive resistant steel, this exceptional structure contributes to the long service life of the machine. The lower section of the machine is fabricated to form a hopper within which the abrasive return screw conveyor is installed to carry the spent abrasive to the bottom of the bucket elevator. Exit Vestibule Similarly, to the Entrance Vestibule, the Exit Vestibule is a section of the machine which ensures adequate isolation of the blast cabinet and serves as a protection from dust and noise. It is ventilated, it features abrasion resistant rubber curtains, which allow workpieces to be processed by the machine while keeping abrasive inside the blast cabinet. ABRASIVE REMOVAL The Brush-Off and Blow-Off are designed to remove the abrasive which has remained on the workpieces after the blast cleaning process. The system consists of a rotary brush and a blower with nozzles. Brush-Off The rotary brush removes the remaining abrasive from horizontal surfaces. The brush is driven by a gear-motor with adjustable rotation speed. The working height of the rotary brush is adjusted automatically depending on the height of the cleaned workpiece, the available range is 0 to 12”. The frame of the cleaning system features an abrasive trough and a double-sided screw conveyor for the transportation of brushed abrasive to both sides, where it falls onto the longitudinal screw conveyors. Collisions between the work pieces and this system are prevented by a safety ramp strip. Blow-Off The Blow-Off is a heavy-duty blower for the removal of dust from processed workpieces. The elevation of the air nozzles is controlled from the control panel or automatically together with the Brush-Off. ABRASIVE RECIRCULATION Abrasive recirculation is a very important system of the machine and it consists of four main components. Longitudinal Screw Conveyors As the material is being blasted in the main blast chamber, the longitudinal screw conveyors, which run the full length of the inlet vestibule, the main blast chamber and the exit vestibule, reclaim and transport the spent abrasive to a transverse screw conveyor. The Blast Cabinet sections of the trough and the screw conveyor are made of a high-quality steel and the screw flights are made of manganese steel. The S series machine is designed to work on a totally flat floor and no excavation or pit is necessary. To accommodate this and to ensure the maximum sized workpiece can be completely treated, the machine is supplied with 2 longitudinal conveyors. Longitudinal screw conveyors drives:                                                                      2 x 2HP Transverse Screw Conveyor The transverse screw conveyor transports the abrasive to a bucket elevator. The trough and the screw conveyor are made of a high-quality steel and the screw flights are made of a manganese steel. Transverse screw conveyor drive:                                                                             1 x 2HP Bucket elevator The bucket elevator is installed at the side of the machine and is used to elevate the abrasive vertically to a separator. It is operated in the sub-pressure regime and is ventilated. It is manufactured very robust and features a single length of steel, folded on CNC press brakes to ensure absolute vertical alignment. The bucket elevator’s head section accommodates a pulley which is driven by a motor- reducer. A set of take-up plates at the head section serve to maintain elevator belt tension. The bucket elevator’s boot section pulley has a sensor of rotation. In case of an emergency stop of the elevator, which may well occur when the elevator’s belt is under- tensioned, the control system prevents overloading and failure of the screw conveyors. In the event of stoppage, all components used in the recirculating process are automatically switched off. The bucket elevator shafts are mounted on dust-tight bearings. The elevator’s belt is made from a reinforced transportation belt highly resistant to abrasion. Pressed steel buckets are fastened to the belt with special concave head bolts and oval backed washers to ensure even distribution of load to ensure they do not protrude through the rubber belt onto which they are attached. They are very easy to replace and need no special tooling. The motor reducer is protected by a motor safety relay and is provided with a brake to prevent reverse motion of the belt. Bucket elevator motor:                                                                                  1 x 4HP Abrasive Cleaning and Storage hopper The Bucket Elevator discharges the abrasive to the Separator where the large impurities are retained on a screen-mesh (and disposed to a trash bin) and the abrasive is cleaned by the use of an air- operated dynamic cascade system. The abrasive to be reused is cleaned very carefully and thoroughly. The clean abrasive fills a storage hopper from which the abrasive is supplied to the turbines. The supply of the abrasive to the turbines is controlled by adjustable shut-off gate valves. TURBINES The turbines are located on the blast cabinet and set at an optimum angle to blast shot directly at all the surfaces of the material to be blasted. The AH 350 turbine is of a time-proven design and has an exceptionally long service life. The housing of the turbine body is made of hot-bent manganese steel plates. On the inside of the housing are replaceable protective liners made of hardened steel and manganese steel from 5/16” to 3/4″ thick. Alternative brand turbines may be supplied on the machine (subject to approval) AH 350 turbines are provided with blades which are fixed to the one-sided bare wheel. The blades and the bare wheel are made of a hardened tool steel. The impeller and control cage are also made of a hardened tool steel. The feed spout of a turbine is made of carbon steel, but the internal surface of the elbow is additionally carburized. The abrasive blast pattern can be easy adjusted and set from the outside. The turbine’s parts are easily accessible from the outside with no necessity to dismantle the whole turbine. VENTILATION Discharged air is subject to the 2nd stage of filtration in a caisson featuring fine filters made of polyester non-woven fabric. The unique design of the caisson also ensures noise reduction. Deducting rate: < 2 mg/m3 Dust Collector The dust collector features a large separation chamber with enhanced filtration area and an air jet pulse for improved dust shake off from the filter cartridges. The electronic control system monitors pressure drops on the filtration cartridges and thus ensures a more thorough filtration as well as extended life of the cartridges. The suction pipe installed underneath the housing of the fan is routed to the initial separation chamber mounted on the Dust Collector. Inside the chamber, the air stream slows down and by the same token its carrying capacity is reduced to such a degree that large contaminant particles fall directly into a waste container. Only the remaining fine contaminant particles settle on the filter cartridges. As a result, the workload for the filter is extremely low and yet a very high degree of separation is attained. Filter cartridges are cleaned alternately. The Dust Collector hopper features a screw conveyor For the automatic transportation of dust to the Mini Bag located on the side of the machine. The waste bag has attached handles for easier transport by a forklift. ELECTRICAL CONTROLS All machine subassemblies are electrically controlled in a central control panel. Only standardized control panels are used, provided with a forced ventilation system. The driving motors are protected by automatic switch-off elements and safety relays. The sub-assemblies are manufactured to the safety classes corresponding to their application types.
