Product Introduction：

Hydraulic open-box sand making machine is a special equipment that mainly uses pebbles to produce sand and stone for construction. Because the sand and stone produced by hydraulic open-box sand making machine are uniform in particle size, good in particle shape, and high in compressive strength, they are more in line with the requirements of high-standard construction sand than natural sand and sand and stone produced by hammer crusher, and they play an irreplaceable role in various ore fine crushing equipment.

The hydraulic open-box sand making machine is an improvement on the "river pebble sand making machine". The traditional sand making machine has no hydraulic power system, so it takes two or three workers one or two hours to open the back cover. The advent of the hydraulic open-box sand making machine solves this problem. One-click opening of the box not only makes it easy to replace the hammer head, side plate, and top plate, but also can quickly solve the problem of material blockage! The whole process only takes 5 minutes, which saves about 3-4 hours of opening and closing the back cover compared to traditional equipment, saving time and labor.

Product Advantages：

1. It can be mass-produced, suitable for large-scale production with a processing capacity of 50-300 tons/hour;

2. Low production cost, the production cost of finished sand and gravel per ton is only 3/5 of that of conventional production lines;

3. Large crushing ratio, high degree of production automation, low energy consumption, and large crushing ratio;

4. Quick investment recovery, short payback period, investment can be recovered in 4-5 months;

5. Good plasticity, with shaping function, the product is in the shape of a cube;

6. The particle size is excellent and the finished product particle size is excellent and meets the standards.

How it works：

The hydraulic open-box sand making machine is a machine where the ore is fed from the feed port and slides down along the screen plate. The ore on the screen is crushed by the carbide hammer on the high-speed rotating rotor during the falling process, and flies to the first cavity lining plate at a very high speed along the tangent direction. The lining plate hits the ore back and collides with other ores thrown out from the back of the rotor, so that the ore continues to be crushed. The material enters the first crushing chamber and collides with the plate hammer on the rotor, and then enters the second crushing chamber for continued crushing. The crushing of the material in the crushing chamber not only forms the crushing of the material, but also completes the shaping of the material in the cavity until the particles become the required size, and the formed sand is discharged from the discharge port. The hydraulic open-box sand making machine works by crushing the ore on the principle of stone hitting stone. It has a selective crushing effect, and the particle size of the crushed product is relatively uniform, and most of the shapes are cubic stones. It is widely used in the construction of bridges, highways, docks, and airports.
