Sand Maker

Sand making machine is widely used in various kinds of hard and brittle materials such as rock, abrasive, refractories, cement clinker, quartz stone, iron ore, concrete aggregate and etc. It is particularly suitable for building sand and road sand. Used for the fine break of various ores, it has replaced the traditional equipments such as hammer crusher, roll crusher and rod mill, and has become the mainstream equipment in the sand making industry.

The working part of the cone type sand making machine is two cones, one is the moving cone fixed on the main shaft, and the other fixed cone is a part of the frame and is standing. The centerline of the moving cone of the main shaft intersects with the centerline of the fixed cone to form an angle ж┬ (about 1бу). The lower end of the main shaft is inserted into the eccentric bush, and the bush rotates around the shaft sleeve with eccentricity, so that the movable cone performs a swinging swing motion along the inner surface of the fixed cone. When the fixed cone is closed, the stone at the place is subjected to a dynamic cone. The crushing, bending, and shearing effects break the place. From the place where the fixed cone is located, the broken stone will fall on the cone bottom due to the effect of gravity. Because the eccentric bush rotates continuously, the moving cone also continuously rotates and oscillates, so the crushing process and unloading The material progresses continuously along the inner surface of the fixed cone.

When the sand making machine breaks the stone, due to the crushing force, a friction force is generated on the surface of the moving cone, and the direction is opposite to the moving direction of the moving cone. Therefore, a moment is formed on the main axis so that the moving cone is eccentrically rotated around the axis. During the exercise, it also performs the opposite rotation movement. This rotation movement can promote more uniform particle size and even wear of the moving cone surface. Stones are crushed, bent and sheared between the two cone surfaces and broken. The stone is free to unload after crushing, so its production capacity is large and its power consumption is low.

Advantages of sand making machine

The cone type sand making machine is a new type of sand making machine today, and the equipment far exceeds the conventional sand making equipment. High yield and stable operation. Each part of our sand making machine is carefully polished and installed. At the same time as the output is high, the finished product has a beautiful grain shape, which greatly promotes the sales of stone materials. Especially in the case of high stone hardness, the advantages are even more obvious. It has been used in many production lines.

When Sand Making Machine is working, the stone material falls straight from the upper part into the high-speed rotating turntable. Under the action of high-speed centrifugal force, another part of the target stone distributed around the turntable in the form of an umbrella produces high-speed impact and high-density crushing. After hitting each other, eddy currents are created between the impact crusher’s turntable and the casing, causing multiple blows, friction, smashing, and comminution until the required grain size.
