Wheelabrator HB 16/22 Overhead Rail Shotblast MachineBlast wheelsTITAN blast wheels provide a very efficient abrasive pre-acceleration, which allows for short treatment times, highperformanceand a superior blast process.

Rotation and oscillationTo achieve complete coverage, the workpiece carrying hooks rotate and stop automatically at three different pointsin the blast cabinet.This rotation and oscillation process means that even highly complex workpieces, with hard to reach surfaces, canbe safely and accurately treated. (See picture of rotation and oscillation on the right).

Characteristics• Versatile transport technology• Highly efficient blast wheels• Multiple machine sizes and variations available

Applications• Removal of mill and forge scale as well as rust• Removal of burrs and scales• Increase of surface roughness• Shot peening to increase fatigue strength

Workpiece DimensionsMax. Ø: 1,600 mm Max. height: 2,200 mmMax. workpiece-/hanger weight: 800 kg

Method of operation

The workpieces are directly hung on the rotating hooks or on support hangers. These are pushed to the drag unitjust in front of the blast chamber. From here, the rotation hook is automatically dragged into the blast chamber.

After the hook is in the chamber, the door is closed by an electric motor and locked electro- pneumatically so that anunauthorised opening during the blast cycle is prevented (Alternatively, the machine can be supplied with manualdoor operation).

The blast cycle is running according to the pre-selected blast time and the blast cycle‘s ending is optically indicated.

After the standstill of the turbines the door is opened so that the workpieces can be dragged in resp. out; the blastedhanger will be dragged out automatically.

The dust produced during the blast process is exhausted by a filter unit and then separated.

Wheelabrator HB 16/22 Overhead Rail Shotblast MachineBlast chamberin welded construction, made of manganese steel. In the zone of direct impact the chamber is exclusively lined withreplaceable scaly arranged wearing plates from manganese steel. Hung in at the side wall and the bottom, screwedbelow the top.

A motor-driven double swinging door is installed at the front of the chamber. This door is made of steel plate andprotected by rubber against wear.

Incl. electro-pneumatic safety locking.

Due to the operation of the door by motor drive the following automatic process is given:Drag in, doors close, blast, doors open, drag out.

The blast chamber roof is slotted for the movement of the rotating hook and is sealed by a combination of a rubbergasket and brushes as well as a manganese hard steel labyrinth. The overhead rail system and the device forrotating and dragging the hanger are held by a support steel construction which is mounted on the roof of the blastchamber.

Abrasive collection hoppermade as well of manganese steel, mounted directly below the blast chamber with screw conveyor, protected by agrid cover. The screw conveyor is driven by the gear motor of the bucket conveyor.

Bucket elevator unitwith upper and lower roller stations in dust-proof bearings, bucket elevator belt of synthetic fibre with bucketsretained by special screws, upper belt tensioning unit and a geared motor as drive with brake unit. Including rotatingcontrol in order to avoid a flooding of the abrasive flow.

Abrasive reclamation unit and silodesigned as cascade wind sifter with adjustable retaining flap for achieving a constant thin veil of abrasive as well asan air regulating flap for the regulation of the air washing intensity with mounted deflecting separator for separation ofcoarse blown off particles.

The particles which are carried of by the air flow and being separated by the deflector fall through a hose withlip-type valve at its end into a customer-provided container.

The abrasive falls down into a silo which is covered by a perforated sheet for separation of bigger particles. This siloforms the bottom part of the reclamation unit, and its level can be checked through a vision window.

Maintenance platformas an access to the abrasive recycling. Execution according to UVV with cover plate. Rail made of square pipes,falling protection and ladder.

Wheelabrator HB 16/22 Overhead Rail Shotblast MachineAbrasive control unitsDosing units for the ROTO-JET turbines. Executed as closed steel housing with lockable inspection opening. Thecontrol unit which interrupts the abrasive flow is manufactured of hardened manganese steel and is equipped withtwo bearings. The abrasive quantity is being controlled by a manually adjustable stop screw and is indicated at theammeter at the electrical switch and control box. In order to be able to dismount the abrasive control unit from thesilo for repair works and to avoid any abrasive outflow for each unit one manual slide is installed in front of theabrasive control unit.

ROTO-JET Turbines type 15.3in double disk design, equipped with 8 insertable throwing blades each and central mechanical abrasivepre-acceleration. The high quality welded housing is completely wear resistant lined and equipped with robustbearings in well proportioned dimensions.

The faces are protected with hardened plates produced of tool steel. The blast wheel can easily be dismounted onthe side of the feeding pipe without detaching the motor.

Overhead rail systemin Y-shape according to the offer drawing. With point switch changing automatically, rail profile, steel- and supportconstruction which is designed for a load of max. 800 kg for each hook.

Rotation hookswith two easy running bogies, connected by traverses, with loading hook and sealing cap in manganese hard steelas protection against wear.Loading capacity: each max. 800 kg

Hook drag and rotation unitmounted on the roof of the blast chamber. For dragging in and -out and for an equal rotation of the hooks in front ofthe turbines.

Oscillation deviceThe rotating hanger moves into the first blast position, then into the central position and after that into the third blastposition. The positions can be modified up to 2 x 150 mm by means of flexible limit switches in a C-rail.

Electric and pneumatic switch and control unitfor the central control of the machine via a PLC type Siemens S7-300 with aCPU 313C. With Automatic Star-Delta switching for all motors exceeding 7.5 kW power with all the contactors andprotection for the direct switching of all other motors installed as well as ammeters for controlling and adjusting theROTO-JET turbines.

The control of the machine is made by means of a Siemens Touch Panel KTP 600 and by means of push buttons foractuations which are required for every operating cycle. All fault and operating notifications are indicated at the KTP600.

20 blasting programs can be stored and directly selected.
