Abstract
A grinder/dryer having a plurality of beater blades carried on a rotating shaft in a cylindrical housing, including one or a plurality of grinding members on the cylindrical side wall. The grinding members are adjustably positioned at different locations within the cylinder. The grinding members may be provided in a variety of different combination of elevated ridges and/or valleys used to dry and classify materials.
Claims20
A single pass material processing apparatus comprising:
- a. a cylindrical housing having an interior side wall and an inlet end having at least one of an air inlet and a material inlet, said air inlet admitting forced air at an elevated temperature into said cylindrical housing, said cylindrical housing further having a material outlet and defining adjacent processing sections being longitudinally offset from each other along the length of said cylindrical housing;
- b. a shaft centrally located in said cylindrical housing said shaft comprising;
- c. a plurality of beater blades;
- d. at least one retention member separating said adjacent processing sections;
- and
- e. at least two grinding members, said at least two grinding members including a first grinding member and a second grinding member, said first grinding member comprising a first contact surface comprising at least one mesh or screen element, and said second grinding member comprising a second contact surface comprising at least one mesh or screen element different from said at least one mesh or screen element of said first contact surface, said first and second grinding members being positioned proximate to said interior side wall, wherein said first grinding member is disposed in one of said adjacent processing sections and said second grinding member is disposed in another of said adjacent processing sections;
- wherein the beater blades are each positioned to rotate with the shaft and further wherein rotation of the beater blades is constructed and arranged to strike material in said cylindrical housing and to cause the material to strike the said grinding members, reducing said material in size.

A single pass material processing apparatus comprising:
- a. a cylindrical housing having an interior side wall and an inlet end having at least one of an air inlet and a material inlet, said air inlet admitting forced air at an elevated temperature into said cylindrical housing, said cylindrical housing further having a material outlet and defining at least two adjacent processing zones, including a first processing zone and a second processing zone;
- b. a shaft centrally located in said cylindrical housing said shaft comprising at least one agitator disk assembly, said at least one agitator disk assembly having at least one scraper blade;
- c. a plurality of beater blades on said shaft;
- and
- d. at least two grinding members including a first grinding member and a second grinding member, said first grinding member comprising a first contact surface, and said second grinding member comprising a second contact surface, said first contact surface having a different shape than said second contact surface, said first and second grinding members being positioned proximate to said interior side wall, wherein said first grinding member is disposed in said first processing zone and said second grinding member is disposed in said second processing zone;
- wherein the at least one scraper blade and the beater blades are each positioned to rotate with the shaft and further wherein rotation of at least one of the at least one scraper blade and the beater blades is constructed and arranged to strike the material and to cause the material to strike the at least two grinding members, reducing said material in size.
