Roller Conveyor Blasting Machine
Description
The billet are placed on inlet roller conveyor and pass through blast zone, wheels are located as required to skrike all surface of the billet uniformly. at the exit end clean billets drops on to storage
rack.
Working principle
shot blasted billets helps in inspection for defects like crackes accurately at faster rate with removal of the mill scale, pin holes and other surface defects in the billets are more readily visible to the grinders.
Applications
Billets; relatively short, heavy steel bars with a quadratic profile are usually made in continuous casting or hot roll lines. After production their surface finish must comply with grade SA 2.5 minimum, i.e. the surface must be practically free of rust and scale.
Technique parameter
This blast system allows the derusting and descaling of billets with cross-sectional dimensions of max. 180 x 180 mm at cycle times of 20 seconds. Equipped with 4 OR 8sets Long Life high performance turbines and 2 blast media recycling & classification systems, this blast machine can run at processing speeds of up to 90 m/min.
