Abstract
Continuous compounding systems include a feeding section and a compounding section. Method for compounding or mixing solid matter and liquid matter include providing a continuous compounding system, adding matter to the continuous compounding system, and mixing or compounding the matter.
Claims20
A method of providing a mixture, the method comprising
- providing a continuous compounding system that includes a feeding section, a roller cylinder located downstream of the feeding section, and a side feeder coupled to the roller cylinder,
- adding initial formulation to the feeding section and upstream of the side feeder,
- conveying the initial formulation from the feeding section to the roller cylinder after adding the initial formulation to the feeding section,
- applying pressure to the initial formulation with the roller cylinder to form an initial material,
- adding first dry solid matter and liquid matter to the side feeder to form a slurry in the side feeder, the slurry including the first dry solid matter and the liquid matter,
- adding the slurry to the roller cylinder to combine with the initial material after applying pressure to the initial formulation to form the initial material, and
- mixing the slurry and the initial material in the roller cylinder to provide the mixture.

A method comprising
- providing a continuous compounding system that includes a feeding section and a compounding section located downstream of the feeding section,
- adding initial formulation to the feeding section upstream of the compounding section,
- conveying the initial formulation downstream from the feeding section to the compounding section,
- applying pressure to the initial formulation with the compounding section to form an initial material,
- mixing dry solid matter and liquid matter to form a slurry separate from the initial formulation,
- adding the slurry to the initial material through a port in the compounding section that is downstream of the feeding section;
- and
- mixing the slurry and the initial material in the compounding section,
- wherein applying pressure to the initial formulation in the compounding section occurs upstream of the port.
6 more elements
A continuous compounding system comprising
- a feeding section configured to receive initial formulation,
- a compounding section configured to receive the initial formulation from the feeding section and to apply pressure to the initial formulation to form an initial material, and,
- a side loader coupled to the compounding section and a liquid injector, the side loader is configured to convey solid dry matter into an open port formed in the compounding section at a location downstream of the feeding section, the liquid injector is configured to add liquid matter to at least one of the compounding section and the side loader at the location downstream of the feeding section.
