Gostol TST P series roller conveyor blast machines

Roller conveyor blast installations of the P series are engineered for continuous pass-through treatment of steel plates, structural beams, profiles and welded frames. Angled blast wheels ensure thorough descaling, rust removal and primer prep during a single automated cycle.

Heavy duty conveyor steel rollers with protective sleeve guides for structural metal beams
Height adjustable rotating cross brush paired with high output blow-off nozzles at exit
Wear resistant manganese steel liner plates safeguarding internal chamber walls from erosion
Automated workpiece presence detection sensors optimizing motor start and abrasive gating

Gostol TST VK series spinner hanger blast machines

Hanger chamber blast machines of the VK line are designed for finishing batches of shaped alloy items, forged components and welded assemblies. Suspending parts on rotating hooks prevents contact damages while granting complete abrasive exposure across recessed internal pockets.

Rotating hook assemblies with reversible directional rotation and adjustable speed settings
Overhead monorail handling systems available in straight, Y-track and closed loop layouts
Multi-layer rubber labyrinth seals at chamber doorways preventing abrasive pellet leakage
Bottom collecting screw conveyor feeding a bucket elevator and air wash separator circuit

Gostol TST GG series rubber belt tumble blast units

Compact tumble blast units of the GG series utilize perforated rubber belts for gentle bulk cleaning of small parts. Smooth tumbling within the cradle protects threads, machined faces and edges from mechanical damage while belt holes allow rapid abrasive drainage into the separator.

Endless perforated rubber belt engineered with raised tumbling ribs for thorough part turnover
Drum end plates lined with wear resistant protective inserts preventing side rim friction
Automated hydraulic skip loader for streamlined bulk material charging into the blast barrel
Tension adjustable drive drum assemblies with sealed heavy duty bearing protection units

Gostol TST G series steel slat tumble blast machines

Heavy duty blast machines of the G series incorporate interlocking steel conveyor slats for large metal pieces up to 5000 kg. Robust alloy links withstand repeated impacts of dense forgings while high throughput IR wheels clean away heat treat scale, burnt sand and rough surface flaws.

Interlocking conveyor apron made from hardened heat treated alloy steel slats for durability
Replaceable side guide segments and overlapping seals preventing workpiece entrapment in gaps
High strength roller chains featuring hardened connecting pins for smooth torque transmission
Integrated magnetic separation drum removing residual sand impurities from reusable abrasive

Gostol TST K series rotary table blast machines

Versatile K series blast units with horizontal rotating tables provide flexible finishing for individual items, heavy forgings and flat structural plates. Compact footprints eliminate pit foundation requirements, enabling rapid assembly on standard factory reinforced floors.

Perforated rotary table plate protected by replaceable wear resistant manganese steel covers
Interchangeable rubber and metal curtain liners shielding internal doors and roof enclosures
Smooth electromechanical table drive mechanism with adjustable speeds for diverse metal shapes
Integrated dry cartridge dust collector featuring automatic reverse pulse jet cleaning cycle

Inspection and renewal procedure for Gostol TST IR blast wheel blades

Routine monitoring of throwing blades on IR blast wheels prevents rotor imbalance and lowers dynamic stress imposed on motor shaft bearings. During continuous multi-shift foundry operations, visual checking of blade curvature is conducted after forty hours of machine run time.

If deep erosion cavities or edge thinning exceeding three millimeters are identified, the complete blade set must be replaced simultaneously. Fitting mixed blades with unequal weight distribution is prohibited by factory guidelines to avoid severe vibration oscillations.

Each blade component slides into rotor hub slots until seating firmly against retainers with locking pins. Proper mechanical assembly ensures expected projection velocity of metallic shot abrasive.

Installation and alignment of control cage and abrasive distributor

Positioning of the distributor impellor and stationary control cage defines the exact discharge hot spot inside the Gostol TST blasting chamber.

Angular deviation of the discharge window relative to workpiece flow results in unwanted erosion of protective housing liners and drops cleaning efficiency.

During wheel rebuilding, the clearance between the rotating impellor periphery and stationary sleeve bore is verified using precision feeler gauges. Retaining fasteners securing the control cage assembly are torqued using a calibrated wrench to factory specified values.

Following mechanical alignment, an operational test using a target sheet confirms uniform abrasive concentration on target work surfaces.

Operation and maintenance guidelines for P series roller conveyors

Transporting heavy structural beams and welded assemblies through P series blast enclosures requires smooth rotational synchronization across entrance and exit roller beds. Infiltration of abrasive dust around drive sprocket chains leads to premature tooth wear and binding of conveyor rollers.

Scheduled upkeep includes weekly compressed air blow-down of bearing housings and grease replenishment using high temperature lubricants in sealed friction points.

The working height of the revolving nylon cross brush and high volume exit blow-off fan is adjusted by operators to match plate thickness for thorough shot sweeping. Timely brush segment renewal avoids media carryout past rubber labyrinth doors.

Adjustment of overhead monorails and rotating hook units in VK models

Uninterrupted circulation of workpiece carriers inside VK blast chambers relies on systematic inspection of monorail switch tracks and hook rotation drives. Working directly within abrasive deflection zones, rotating spindle assemblies are sealed with rubber labyrinth barriers and deflector hoods.

Operators inspect protective seals monthly and check gear oil levels in the hook drive transmission box. When uneven spindle rotation or jerking occurs, carriage support rollers and drive belt tensions are inspected for alignment errors.

Secure workpiece hanging on rotating hooks eliminates drop hazards and swing deviations under intense metallic shot bombardment.

Tensioning and upkeep of perforated apron belts in GG and G units

Smooth performance of GG rubber belt tumble units and G series steel slat machines depends on symmetrical conveyor track tensioning. Belt misalignments cause severe lateral friction against barrel drum end plates and let parts slip through bottom clearance gaps.

Drive drum tensioning studs are adjusted symmetrically on both chamber flanks while tracking sag depth along the lower return loop. Belt perforations are inspected daily to remove jammed metal scrap and distorted pellets that hinder media drainage into the separator elevator.

Scheduled belt washing and barrel guide segment checks maintain reliable continuous operation.

Enclosure sealing integrity and cartridge dust collection servicing

Reliable negative air pressure and dust containment within Gostol TST enclosures protect surrounding factory floors from airborne particulates. Multi-layer rubber entrance and exit curtain strips are examined at each shift handover for tear lines or abrasive thinning.

Worn sealing strips are renewed in individual sections without dismantling structural entrance frames. Dust collector filter cartridges undergo automated reverse pulse jet cleaning using dry compressed air at five bar pressure.

Tracking pressure differentials across manometers indicates when filter cartridges require replacement to sustain extraction airflow.
