Features And Functionalities

An efficient abrasive recycling system is the indispensable prerequisite for a high blasting capacity, low system wear and short blast times.
Used abrasive is collected from the blast chamber by a screw conveyor or a vibrating chute, transferred to a bucket elevator and delivered to a high-performance air classification system.
Fitted with an adjustable air vane, the cascade classifier separates dust and debris from the recovered abrasive.
Integrated impact separators, coarse screens and an adjustable air wash system efficiently remove the contaminants.
In order to utilise the abrasive as efficiently as possible, parameters such as the dosage of the abrasive and its feed to the wheel blades must be adjustable both conveniently and reproducibly.
Electro-pneumatic slide valves are fitted as standard to allow precision dosing of the blast media and to ensure an instantaneous shut-off to prevent abrasive from being fed to the turbine at the end of the set blast time.
The abrasive feed rate and the associated blast pattern (hot spot) are conveniently adjustable on the external abrasive inlet.
Chamber dimensions, along with the number, arrangement and efficiency of the turbines, are vital and well-matched parameters that ensure optimum performance of our blast systems.
