Shot Blasting Machine is widelyused for automated surface treatment and finishing of castings. In shotblasting methods the stream of shots is created and formed by blasting turbines, making up a kinetic and powerful system comprising a separating rotor, an adapting sleeve, and a propelling rotor equipped with blades. It is a surface treatment method using high-velocity steel abrasive.
Shot blasting is a method withinwhich it is possible to get high-quality cleaning and surface material forsubsequent finishing processes. The shot blasting performance- i.e. the quality of shot-designed facades depends on the actual design and operationalparameters of the unit whilst the quality of relevant parameters are connected with the geometry of turbine components and the level of its combination with the separator system.
The flow of the blasting mediumenhances the integrating factor of the method line, starting fromthe blasting hopper, throughthe propeller turbine, casting treatment, division of a contaminated abrasive mixture, to its recycling and reuse.
Working of Shot blasting machine
In the shot blasting process, astream of abrasive medium with the wanted kinetic energy is produced andpropelled onto the surface to be used. The stream of the cleaning tool, being a mix of metal shots, is a dynamically changeable system, including an intense and departed zone, as revealed by numerous studies.
The actual proportion ofparticular zones in the construction of the shot stream considerably changesthe shot blasting efficiency. The greater the combined zone, the more effective the process. Other determinants of shot operation efficiency include:
Abrasive delivery method:
There are two ways ofaccelerating the steel shot:
By compressed air:
This system is fit for lowerproduction uses where the most flexibility is needed. These systems are veryflexible in that the shot can be transferred horizontally through a rubber hose and nozzle attachment. This enables uses in finishing processes of steel frames and weldments thereby restoring hand tools. Because of this, an air blasting machine for a product line is costly related to a centrifugal blasting machine.
On the other hand, the same taskusing radial wheel turbines only needs a total of 100 Hp distributed to betweenone and a number of turbines housed in the same machine. Only one or two workers are needed for such a shot blasting machine.
By centrifugal turbine: Centrifugal wheel blasting is themajor common blast cleaning system as well as the most effective andenvironmentally friendly method. The turbine provides abrasive shots by radial force in a special and controlled way, speed, and quantity. The purpose of the turbine is comparable to that of a fan or centrifugal pump.
Shot Blasting Machine may useone or a number of turbines placed in such a way that the abrasive blast designcovers the entire surface of the element to be shot erased. The shape and size of the elements determine the number of turbines used in a machine. The control of the turbine motor is based on the quality of cleaning required and the speed of the element.
Technologies being used in Shot Blasting Machines
There are two Technologies usedin Shot Blasting i.e. Air Blasting & Wheel Blasting
· Air Blasting - It is a technique i.e.cast-off to treat metal the way the systems want. It uses air pressure from theblast room, also known as the blast cabinet.
· Wheel Blasting - The wheel blastingtechnique uses a wheel with the centrifugal force for propelling the abrasiveagainst the surface.
