Working Principles of Three Common Shot Blasting Machines

The working principle of the shot blasting machine is the basic content that many users who are new to the shot blasting machine want to know. Only by knowing the details of the working principle of the shot blasting machine can you better choose the suitable shot blasting machine.


1. Working principle of crawler shot blasting machine


The working principle of the crawler type shot blasting machine: after adding the workpiece to the cleaning room, the machine starts, the workpiece is driven by the drum and starts to turn over, and at the same time, the shot blasting machine throws the projectile at high speed to form a fan beam, which is evenly hit On the surface of the workpiece, so as to achieve the purpose of cleaning, the thrown projectiles and sand particles pass through the small holes on the rubber track, flow into the steel mesh at the bottom and sieve, and are sent into the elevator through the screw conveyor, and the elevator is lifted to the separator. The dust is sucked into the dust collector by the fan, and after being removed by the dust collector, the dust falling into the dust collecting box can be removed on schedule. The waste sand flows out from the waste pipe and can be recycled by the user. The shot-sand mixture is recycled into the chamber by the shot-returning pipe, and reused after the separator is separated.


2. The working principle of the shot blasting machine


The working principle of the pass-through shot blasting machine: a specified number of workpieces are added to the cleaning room. After the machine is started, the projectiles thrown by the shot blasting machine at high speed form a flow shot beam, which hits the surface of the workpiece evenly, so as to achieve cleaning and strengthening. Purpose. The thrown projectiles and sand particles flow into the elevator and are lifted to the separator by the elevator for separation. The dust is sucked by the fan and sent to the dust collector for filtration, and the clean air is discharged into the atmosphere. The dust on the cloth bag falls into the dust collecting box at the bottom of the dust collector by mechanical vibration, and the user can remove it regularly. The waste sand flows out from the waste pipe. Reusable. The recycling process is the same as the crawler shot blasting machine.


3. The working principle of the tumble belt shot blasting machine


The tumble belt shot blasting machine mainly uses the high-speed rotating impeller to throw the projectile on the workpiece that is continuously turned in the drum, so as to achieve the purpose of cleaning the workpiece, which belongs to the scope of casting machinery. It is suitable for sand cleaning, rust removal, scale removal and surface strengthening of castings and forgings under 15Kg in various industries. The tumble belt shot blasting machine is suitable for cleaning all kinds of castings and forgings that are not afraid of collision and scratches. It is an ideal equipment for cleaning the residual sand and oxide scale on the surface of the workpiece in small heat treatment workshops. Geared motor, etc.
