Abstract
A mechanism and method for the comminuting and grinding of brittle grinding stock including a roll press with the material passed from the roll press to a deagglomeration drum which co-rotates with the tube mill. The material from the deagglomeration drum is passed to the tube mill and the material from the tube mill being passed to a separator. In one form the material from the separator is passed to a second separator and the coarser products from the second separator are led back to the tube mill with an airstream conducting the finer material from the tube mill to the first separator.
Claims15
A method for comminution and grinding of brittle grinding stock comprising the steps:
- pressing material to be comminuted by a roll press;
- deagglomerating the output of the roll press in a deagglomeration chamber having only the material to be comminuted;
- separating the material from the deagglomeration chamber in a first cyclone separator into fine and coarse fractions;
- and
- grinding the coarse fraction in a tube mill.
The method for comminution and grinding of brittle grinding stock comprising the steps:
- pressing material to be comminuted by a roll press;
- deagglomerating the output of the roll press in a deagglomeration chamber;
- separating the material from the deagglomeration chamber in a first cyclone separator into fine and coarse fractions;
- grinding the coarse fraction in a tube mill;
- carrying finer material from the deagglomeration chamber to the separator by an airstream that first passes through the tube mill;
- and
- carrying coarse material by a separate coarse material moving means to the separator.
A mechanism for the comminution and grinding of brittle grinding stock, comprising in combination:
- a tube mill including grinding bodies for reducing an average particle size of the grinding stock;
- a deagglomeration drum co-movable with the tube mill and connected at an outlet of said tube mill, said deagglomeration drum being free of grinding bodies;
- a roll press for receiving material to be comminuted and having a discharge connected to an inlet of the deagglomeration drum;
- and a separator connected to receive materials from an outlet of the deagglomeration drum and connected to deliver coarse materials to the tube mill.
A mechanism for the comminution and grinding of brittle grinding stock comprising in combination:
- a roll press for receiving materials to be comminuted and being operable to press said brittle grinding stock to cause fracturing thereof;
- a deagglomeration chamber connected to receive material from the roll press and being operable to breakup said fractured grinding stock, said deagglomeration chamber being free of grinding bodies;
- a separator connected to receive materials from said deagglomeration chamber and to separate fine materials from coarse materials;
- and a tube mill connected to receive coarse material from the separator chamber and being operable to reduce the course material by grinding, said tube mill including grinding bodies.
