These steel about two to four inches e, cast iron balls or round er to the rinsing My improved mill is very e length ofscrubber with However, its action is greatly enhanced by a plurality and in practice I have used four ordinarily, as illustrated in the drawings. In the operation, gravel, cont clay and rotten ston material, is introdu aining impurities such as e and other hard stratified ced into the drum at II by any suitable means, as by chute or belt conveyor. A quantity of water is introduced at the same time by hose or otherwise, enough to reduce the mass to a muddy consistency. The machine is then revolved terial to stratify in the agitating bars I I and the steel balls permit them to tumble action which quickly disintegrates all clay a all tendency of the mathe drum being obviated by which carry the material together up at the side and down with a crushing rotten stone or like impurities within. the mass of gravel and does not in any way grind the gravel. It is not the intent to grind the gravel.
-As soon as the machine supply of the gravelly is started, a continuous material to be treated is fed into the drum with the necessary water to secure the muddy consistency and the action, the same being continuous after the start.
Owing to the incl me of the drum this muddy material with the the conical screen 9 and then, owing to the large size of the perforations therein, the material is at once passed and crushed through to the next compartment where the operation is repeated and is repeated a suflicient number oi! times to disintegrate the rotten stone or clay.
When this is accomplished the whole mass of the material is discharged onto the gravel rinsing and grading screen 2 where the rinsing takes.
place. The disintegrated clay and rotten stone is at once washed away and the gravel is passed to a suitable bin or other point or discharge completely prepared for use and all objectionable material removed. v
Having thus described my invention, what I claim as new and desire to secure by Letters Pat ent is:
l. The continuous process of treating gravel to remove objectionable material such as rotten stone, hard clay lumps or the like, comprising moistening the gravel containing such objectionable material until it has a muddy consistency, feeding the gravel continuously, mixing with the gravel disintegrating elements larger than the gravel, agitating the mixed gravel and disintegrating elements until the objectionable material and not the gravel is disintegrated. and while thus agitating the mixture screening out the disintegrating elements and separating the gravel from the disintegrated objectionable material.
2. The continuous process oi treating gravel to remove objectionable material such as rotten stone, hard clay lumps or the like, comprising, feeding the gravel continuously, mixing with the gravel disintegrating elements larger than the gravel, agitating the mixed gravel and disintegrating elements until the objectionable material tumbling balls passes up into and not the gravel is disintegrated, and while thus agitating the mixture screening out the dis-- integrating elements and separating the gravel from the disintegrated objectionable material.
3. The process of treating gravel to remove objectionable material such asrotten stone, hard clay lumps or the like, comprising moistening the gravel containing such objectionable material until it has a muddy consistency, mixing with the gravel disintegrating elements larger than the gravel, agitating the mixed gravel and disintegrating elements until the objectionable material and not the gravel is disintegrated, and while thus agitating the mixture screening out the disintegrating elements and separating the gravel from the disintegrated objectionable material.
4. The process of treating gravel to remove objectionable material such as rotten stone, hard clay lumps or the like, comprising mixing with the gravel disintegrating elements larger than the gravel, agitating the mixed gravel and disintegrating elements until the objectionable material and not the gravel is disintegrated, and while thus agitating the mixture screening out the disintegrating elements and separating the gravel from the disintegrated objectionable material.
5. The process of treating gravel to remove objectionable material such as rotten stone, hard clay lumps or the like, comprising mixing with the gravel disintegrating elements, agitating the mixed gravel and disintegrating elements until the objectionable material and not the gravel is disintegrated, and removing from the gravel the disintegrating elements and separating the gravel from the disintegrated objectionable material.
