Kaltenbach Gietart Sprint 2506

Used Gietart Sprint A2506 blast machine incl. accessories for sale. Due to its robust construction, the Sprint series is particularly suitable for companies with high performance expectations for a high blasting throughput.
This unit has been regularly serviced and is therefore in good condition. The Gietart Sprint 2506 was manufactured in Hengelo, the Netherlands, and is ideally suited for use in a larger steel construction company or steel trade.
The blast machine with a drive-through opening of 2,600 x 600 mm has 6 C380 blast turbines with a V-belt drive of an axial mechanical abrasive pre-acceleration and 11 kW drive power each.
The operating speed is 0.9 - 1.8 m/min and the pass-through speed 0.6 - 10 m/min.
For efficient blasting, round abrasive ø 0.9 - 1.2 mm, 45 - 51HRC or steel wire grit ø 0.9 - 1.2 mm, 1,700 N/mm2 can be used.

Our application engineers will be happy to help you select the optimum abrasive.

The system is suitable for blasting:
Sheets with a maximum width of 2,500 mm and a minimum thickness of 6 mm.
Profiles with a maximum size of 1,000 x 300 mm with a maximum document width of 1,600 mm.
The minimum transport length is 2,000 mm and the maximum transport weight is 1,000 kg/m.
Shorter or thinner parts are transported through the system via a wire basket. The parts to be blasted should be dry with only rust and scale and free of other contaminants such as oil, grease and paint.
The blasting machine consists of a 10 mm thick machine housing with a 4 mm thick manganese lining for protection. In addition, the blast chamber has a bolted 8 mm thick manganese wear strip lining for easy maintenance.

The inlet airlock and outlet airlock are each 1000 mm long and each has 8 rubber curtains to keep the abrasive in the blasting chamber during blasting.
Furthermore, the blasting machine includes a collection hopper with screw conveyor and two bucket elevators, each with a 5.5 kW gear motor and electronic speed monitoring. A transverse screw conveyor from the bucket elevator to the abrasive container as well as an abrasive cleaner with sieve and a 3-fold cascade air cleaning, an abrasive container with a capacity of 1,200 litres without abrasive, an abrasive pre-separator, an inspection platform with ladder, an abrasive control system and an electronic scanning in the roller table for the abrasive control with automatic adjustment to the throughput speed. The workpieces are conveyed through the machine via 4 transport rollers Ø 140 x 2,500 mm and a further 4 transport rollers Ø 140 x 2,500 mm in wear-resistant, hardened solid material.
The roller table drive has 2.2 kW and is electronically adjustable from 0.6 - 10 m/min with digital display in the control cabinet.

Power supply 400 V ± 5%, 50 Hz, 3 ~/PE
Control voltage 230 V AC + 24V DC
Total connected load: approx. 130 kW, motors from 5 kW with star-delta connection
The brush blow-off device has a feed-through opening of 2,600 x 600 mm and an operating power: approx. 16 kW. The integrated workpiece cleaning system uses a rotating brush and a targeted air stream. This consists of a machine housing with collecting hopper, screw conveyor and gear motor, 4 transport rollers Ø 140 x 2,500 mm, a screw conveyor in front of the brush. a safety device for the brush and a cross-flow blower. The brush, screw conveyor and cross-flow blower are integrated in one frame and are adjusted together to the correct height.
The fully automatic extraction system is suitable for continuous operation and consists of:
Cartridge filter type GPF M 12
Capacity 240 m3/min / 15 mbar
Motor 11 kW / 3000 r.p.m.
Filter area 252 m2
Dust emission < 1 mg/m3
Filter housing with inspection doors, frame with dust collection hopper, automatic dust removal valve
12 Ultra Webb filter cartridges Ø 324 x 660 mm
The control cabinet is equipped with a SIMATIC C7-633 text display in German language with operating elements for complete control of the system and automatic starting of the drives. The operating hours counter and the ampere measurement of the individual turbines are integrated in the system and connected to an LED flashing light for signalling alarm messages.
Switching material Siemens, Moeller, Weidmüller
Power supply 400 V ± 5 %, 50 Hz, 3 ~/PE
Cabinet dimensions H x D= 2,200 x 500 mm incl. cable socket 200 mm
PLC control Siemens Simatic S7 - 300
