DS700-AC double chamber continuous pressure blast pot
Disa pneumatic double chamber continuous pressure blast pot is controlled by components such as PLC, level gauge and differential pressure gauge. It can realize the functions of automatic shot feeding and continuous shot blasting without stopping the blasting process to refill the pressure tank with abrasives. This ensures the continuity and effectiveness of shot peening strengthening work, and meets the requirements of automated assembly line operations.
Features and benefits:
- low maintenance costs
- low downtime
- higher production due to higher workload
- dual line deadman system to prevent unchecked operation
- emergency stop button, so that the pot can also be switched off quickly by third parties
- minimum fall in pressure due to air piping, main air tap and mixer pipe being correctly aligned to eachother
- complete use of abrasive in the pot due to its funnel shaped body
- Bolt clamps on pusher line make field repairs easier
- Full flow auto air valve for fast starts and stops
Product Description:
The DS200M-EP abrasive blaster is a comprehensive pressure blasting system featuring an electro-pneumatic control box and a deadman’s handle for enhanced safety and operational control. The complete package includes a 200-litre pressure blast pot equipped with a pop-up valve, a pneumatic main air valve, and a pneumatic exhaust valve with silencer. For abrasive management, it comes with a manual abrasive valve. Operator control is facilitated through a pneumatic remote control system integrated with the deadman’s handle, connected via a 25-meter remote control hose and a 25-meter cable specific to the EP edition. Essential air preparation is handled by a built-in moisture separator. The system also provides 20 meters of heavy-duty 1¼” blast hose, a blast coupling, a nozzle holder, a high-performance tungsten venturi blast nozzle, and a built-in two-step helmet filter for operator protection.
Working Principle of the Abrasive Blasting Pot：
The abrasive blasting pot is filled with abrasive media. After pressure is established inside the pot, the abrasive media, driven by gas pressure and its own weight, enters the mixing chamber of the concentrated shot peening valve through the conical hopper at the bottom of the pot. The two-phase flow of shot and gas is then ejected through the output pipe and nozzle at a speed of approximately 60 meters per second.
Disa abrasive blasting pot: the components
This heavy-gauge pressure vessel is engineered for rugged field service, with its primary function being the containment of abrasive media.
Use an abrasive blasting seive when filling Abrasive Blasting Pot with Abrasive to prevent debris from entering the Abrasive Blasting Pot .
Urethane-coated pop-up valve with external sleeve or long life and fast pres- surization.
It vents outlet air and thereby machine is depressurized instantly. Valve opens automatically with stop of air supply to machine and vice-versa
such as roller conveyors, overhead monorails, or turntables,move parts steadily through the blast zone for uniform cleaning, descaling, or surface preparation. The choice of system depends on part size, shape, production volume, and process needs, ensuring smooth integration into automated lines and efficient blasting performance.
The machine is fitted with pinch valve with hand wheel to control the abrasive flow through blast nozzle.
Large 6” x 8” inspection door for easy access to inside.
Self-cleaning exhaust muffler greatly reduces bleed-off noise.
The machine is provided with automatic mushroom valve (filling valve) for quick refilling of abrasive
The long series convergent-divergent tungsten carbide lined blasting nozzle ensures high velocity, evenly distributed blast pattern & higher blasting output and provides lower wear, longer life and greater resistance against breakage.
The blast hose is highly abrasion resistance with longer life, high flexibility with lower bend radius and light weight and electrically antistatic for safe operation.
An online air filter and pressure gauge is provided.
The blast pot can be switched off quickly, which gives double safety.
