Neophyte Dredges:
Description, Function

this is a centrifugal pump, it disposes of a metallic or wooden pontoon, it neophytes through the middle of the semi-rigid hose or a steel tubing, mix of water and auriferous material which are found in riverbeds, lakes, swamps, etc., pouring the vacuumed material into a conventional slues of an iron or wooden flat in 1 or 2 stretches in countercurrents.

For the suction process of diameters of hose of 6” you would require the contest between divers; for the hoses or tubing of suction of 8” or more inches, the actioning of the neophyte element is by means of a feather with pollipastes and winch actioned by a diesel motor, the head or the terminal of the tube submerged consists in a depth breaker or rotational mill, the mixed material of gravel and water (30% and 70%), is absorbed through a Gravelly pump or of solids of construction of molded or forged steel, wrapped with layers of rechangeable iron, the water-wheel of 4 immovable asps and refilled the faces of impact with extra strong welding, sealing system by burlap conduit, the suctioned material pours into a primary cribble which eliminates the larger gravel than ½”, entering the minor materials to a system of sluices, armored with three layers of thin burlap.

Performances

Suction of 6” = 7 m3/hour: depth of dredging 20 m.

Suction of 8” = 14 m3/hour: depth of dredging 30 m.

Suction of 10” = 19 m3/hour: depth of dredging 30 m.

Suction of 12” = 26 m3/hour: depth of dredging 30 m.

VELOCITY OF THE NEOPHYTE TUBING: 2 to 3,5 m./second.

Recommendations

Each Basic Unit of Production requires in Stand By:

1 solids pump;

1 set of roundlets;

1 rope of burlap conduit;

1 Knelsson recuperation to process the sluices tails.
