As shown in fig. 1-2, the present embodiment provides a wet sand making machine, which comprises a tank 10 and a sand making assembly, wherein the tank 10 is square, the sand making assembly comprises a convex roller 20 connected to the inner wall of the tank 10 through a bearing, a concave roller 30 connected to the inner wall of the tank 10 through a bearing, and a motor; the concave roller 30 is provided with a groove 301, the bump 201 on the convex roller 20 is matched with the groove 301, the concave roller 30 is meshed with the convex roller 20, and the convex roller 20 is positioned right above the concave roller 30; the motor is used for driving the convex roller 20 or the concave roller 30 to rotate, and the discharging end of the hopper 40 penetrates through the tank body 10, and the discharging end of the hopper 40 is positioned above the cross section of the horizontal shaft of the concave roller 30.

The use method and the working principle thereof are as follows:

s1, injecting leaching solvent into the tank body 10 until the liquid level exceeds the cross section of the horizontal shaft of the concave roller 30; the formula of the leaching solution is the prior art and is flexibly selected according to the corresponding raw ore type;

s2, starting a motor to drive the convex roller 20 and the concave roller 30 to rotate;

s3, adding raw ore into the hopper 40, because the liquid level of the leaching solution exceeds the cross section of the horizontal shaft of the concave roller 30, in the rotating process, a certain amount of leaching solution is contained in the groove 301 which is higher than the cross section of the horizontal shaft of the concave roller 30, the raw ore falls into the groove 301 of the concave roller 30 from the discharging end, the leaching solution soaks the raw ore, along with the continuous work of the motor, the groove 301 containing the raw ore is meshed with the lug 201 of the corresponding convex roller 20 to extrude the raw ore to be crushed, the motor continues to work, the groove 301 containing the crushed raw ore moves to the position below the cross section of the horizontal shaft of the concave roller 30, the crushed raw ore is separated from the corresponding groove 301 to enter the leaching solution under the action of gravity, the rotating concave roller 30 continuously stirs the leaching solution to accelerate the dissolution of soluble substances in the raw ore, after the crushing is finished, the motor is stopped, the leaching solution mixed with the crushed raw ore is, and finally, sieving and grading.

To prevent the raw ore from falling directly to the bottom of the tank 10 as it enters the trough 301, the lower edge of the discharge end of the hopper 40 is tangent to the side of the concave roller 30. Normally, there is not clearance between the lower limb of hopper 40 discharge end and the side of concave roller 30, and the crude ore can't fall from the hopper 40, and when the recess 301 of concave roller 30 rotated the lower limb of hopper 40 discharge end, there was clearance between recess 301 bottom and the hopper 40 lower limb, and the crude ore falls in recess 301 under the effect of gravity.

Further, the discharge end of the hopper 40 is arc-shaped to match the side of the concave roller 30, and when the groove 301 is not moved below the discharge end of the hopper 40, the discharge end of the hopper 40 is completely closed by the side of the concave roller 30.

In order to avoid splashing of a small amount of liquid caused by the over-high rotating speed of the motor, the upper end of the tank body 10 is closed, and efficient crushing is realized.

In order to realize the separation of fine dust and sand particles, the dust-removing device further comprises a water tank 50, the tank body 10 is placed in the water tank 50, a plurality of filter holes are formed in the side face of the tank body 10, the filter holes are located below the cross section of a horizontal shaft of the concave roller 30, and the upper end face of the water tank 50 is higher than the cross section of the horizontal shaft of the concave roller 30. The fine dust enters the water tank 50 through the filter holes, and a compact powder layer is formed at the bottom of the water tank 50 under the action of gravity, and it is noted that although part of the fine dust does not settle in time and enters the tank body 10 again, the settling amount of the fine dust is more and more along with the lapse of time, and the hardening phenomenon occurs; the stirred leaching liquid in the tank body 10 is blocked by the side wall of the tank body 10, and the influence on the powder sedimentation in the water tank 50 is small; in order to ensure the liquid level of the leaching liquid, the upper end surface of the water tank 50 is higher than the cross section of the horizontal shaft of the concave roller 30, the water tank 50 is communicated with the tank body 10 through the filter holes, the liquid level is always kept in the crushing process, and the leaching liquid is recycled.
