Abstract
In a device for controlling the aggregations of a mixture of stone materials and binders for the manufacturing of agglomerated stone products, two cylindrical rollers having parallel axes are rotated at different rotation speeds and the distance between said axes is adjustable in order to determine the maximum size of the aggregations.
Claims17
A device for the control of aggregations of a mixture of stone materials and binders, comprising:
- two cylindrical rollers having parallel axes;
- said cylindrical rollers rotating at different and adjustable rotation speeds;
- and
- means maintaining said cylindrical rollers free of contact with each other and for adjusting the distance between said axes being adjustable in order to determine the maximum size of the aggregations present in the final products which pass freely between said cylindrical rollers;
- and
- at least one tank containing coloring oxides, and means for transferring said coloring oxides from said tank to the surface of at least one of said rollers.
A device for controlling aggregations of a mixture of stone aggregate materials and binders for the production of agglomerated stone products, comprising:
- a pair of spaced rollers, each rotatable on its own axis;
- means for varying exit spacing between said rollers, said varying means while varying the exit spacing also maintaining said rollers free of contact with each other;
- said varying means determining the maximum size of the aggregations;
- and
- individual motor means coupled with each said roller for controlling the speed of each of said rollers while maintaining a relative speed difference between the speed rotation of each of said rollers.
A device for the control of aggregations of a mixture of stone materials and binders, comprising:
- two cylindrical rollers having parallel axes and a wall dividing element positioned at an outlet of said rollers;
- said cylindrical rollers rotating at different and adjustable rotation speeds;
- and
- means maintaining said cylindrical rollers free of contact with each other and for adjusting the distance between said axes being adjustable in order to determine the maximum size of the aggregations present in the final products which pass freely between said cylindrical rollers.
