Abstract
The quantity of water on the surface of sand particles is reduced by applying an impact force, e.g. centrifugal force created by a rotating disc. The sand particles thus treated are especially suitable for preparing a green concrete compound or a cement mortar by mixing them with water, gravel and cement.
Claims26
An apparatus for adjusting the water content of fine aggregate comprising:
- means for continuously supplying a quantity of fine aggregate having a quantity of water deposited on a surface thereof;
- projecting means for imparting a velocity energy to the supplied fine aggregate, thereby projecting said fine aggregate in a predetermined direction or directions;
- an impact body having a continuous surface with which the projected fine aggregate comes into collision to apply thereto an impact force stronger than the adhesive force of the water to said fine aggregate at the time of collision, thereby separating an excessive portion of said quantity of water deposited on the surface of said fine aggregate such that after collision said fine aggregate from which said excessive quantity of water has been removed is collected and said separated water is first deposited on said surface of said impact body and then discharged to the outside of said apparatus;
- a receptacle for collecting said fine aggregate from which said quantity of water has been separated;
- and
- a trough for receiving said separated water which flows down along said surface of said impact body.

An apparatus for preparing a hydraulic compound comprising:
- means for supplying a quantity of particles of fine aggregate having water on the surface thereof;
- means for imparting a velocity energy to the supplied particles so as to project said particles;
- an impact body for collision with said particles for applying thereto an impact force stronger than the adhesive force of the water to said particles, thereby adjusting the quantity of water remaining on the surface of said particles to a predetermined value;
- means for adding to said particles a quantity of water and hydraulic substance;
- and
- means for kneading the resulting mixture.

An apparatus for adjusting the water content of fine aggregate comprising:
- means for continuously supplying a quantity of fine aggregate having a quantity of water deposited on a surface thereof;
- projecting means in the form of a rotating member comprising a pair of rotors having mutually parallel horizontal axis, said fine aggregate being supplied by said supply means between said rotors for imparting a velocity energy to the supplied fine aggregate, thereby projecting said fine aggregate in a predetermined direction or directions;
- an impact body having a continuous surface with which the projected fine aggregate comes into collision to apply thereto an impact force stronger than the adhesive force of the water to said fine aggregate at the time of collision, thereby separating an excessive portion of said quantity of water deposited on the surface of said fine aggregate such that after collision said fine aggregate from which said excessive quantity of water has been removed is collected and said separated water is first deposited on said surface of said impact body and then discharged to the outside of said apparatus;
- a receptacle for collecting said fine aggregate from which said quantity of water has been separated;
- and
- a trough for receiving said separated water which flows down along said surface of said impact body.
