Recycling equipments

- In batch plants there are two different systems according to the way in which the recycled material (RAP) is treated: cold or hot.

Cold processes developed by INTRAME

1. RAP is introduced into the dryer’s outlet or into the base of the hot elevator. Maximum quantity to recycle 15%.
2. RAP is introduced into the dryer’s combustion zone through a special ring. Maximum quantity to recycle 15-20%.
3. RAP is previously weighed and then introduced into the mixer. Maximum quantity to recycle 25-30%.
4. Double line system introducing bigger fractions of RAP into the dryer (system described in point 2) and the smaller fractions into the mixer (system described in point 3). Maximum quantity 40%.

Hot process developed by INTRAME. Consists in heating RAP in an additional parallel flow dryer without direct flame, by means of the hot gas coming out from a generating chamber. Afterwards, RAP is weighed and introduced into the mixer. Maximum quantity to recycle 50-60%.

- For Flow-Mix continuous plants, INTRAME offers 3 different equipments for recycling:

1. RAP introduction after continuous weighing into the dryer’s outlet. Maximum quantity to recycle 25%.
2. RAP introduction after weighing into the dryer’s combustion zone through a ring. Maximum quantity to recycle 40%.
3. RAP introduction after weighing into a special dryer with a temperature homogenization zone through a ring. Maximum quantity to recycle 50%.
