A single-hole cross-shaped jet
slurry-making
nozzle comprises a casing, a non-return valve, a spring and a
nozzle, wherein an
air chamber and a
pipe nipple are arranged in the casing, the
pipe nipple is used for being connected with a main air
pipe used for supplying air, and an air inlet hole is formed in the pipe nipple; the non-return valve and the spring are mounted in the
air chamber, one end of the spring is connected with the casing, the other end of the spring is connected with the non-return valve, the non-return valve is connected with the pipe nipple mounted in the casing, and a
tail rod is arranged on the non-return valve and located in the spring; when high-pressure air passes through the air inlet hole, the high-pressure air pushes the non-return valve open and then enters the
air chamber; the open /
closed state of the non-return valve is controlled by the spring; when no high-pressure air is supplied, the non-return valve is pushed by the spring to a
closed state; and the
nozzle is mounted on the casing and communicates with the air chamber, a notched rubber
gasket is arranged in the nozzle, and a nozzle hole of the nozzle is cross-shaped. Through the single-hole cross-shaped jet
slurry-making nozzle, uniform
tailings slurry can be prepared fast and efficiently, and the effects of slurry making and blocky
tailings hammering are remarkable.
