Abstract: In a paint mixing apparatus, a paint can carrying bail retaining device, said device comprising a retaining ring that is movably attached to a blending bucket, said bucket having a diameter selected such that a paint can easily be inserted therein for the mixing or blending operation. The retaining ring has a radius slightly larger than the radius of the mixing bucket plus the thickness of the paint can carrying bail. The retaining ring has a loading/unloading and a retaining position. When the ring is displaced from its retaining position, which is corresponds to its normal position, into its loading/unloading position, sufficient clearance is created to allow the bail to swing freely into a mixing position, where it rests along the outside of the mixing bucket. When the ring is returned to its retaining position, the bail is secured in the mixing position as a result of a lack of sufficient clearance to allow the bail to swing away from its position along the outside of the mixing bucket.

Abstract: A designated amount of recycled asphalt product (RAP) is fed to the pugmill of a batch asphalt plant during the production of hot mix asphalt (HMA) at a controlled rate so as not to overload the pugmill scavenging system. The designated amount of RAP is metered in a RAP weigh hopper, stored temporarily in a RAP holding hopper, and is then fed from the RAP holding hopper to the pugmill at a controlled rate. The feed of RAP to the pugmill, though electronically initiated, is preferably manually or automatically adjustable so as to avoid overloading the pugmill scavenging system while at the same time assuring adequate mixing of the RAP with the virgin aggregate and liquid asphalt. The scavenging system directs vapors removed from the pugmill to the dryer and preferably includes electronically operated dampers connecting the combustion air inlet of the dryer to the pugmill only during the mixing operation and otherwise connecting the combustion air inlet to the ambient atmosphere.
