The sand making machine mainly consists of eight parts: feeder, distributor, cyclone crushing chamber, impeller experience, spindle assembly, base transmission device and motor. Sand-making machine is the key fine-grained molding equipment in the process of machine-made sand production. Sand making machine has the advantages of high efficiency, good molding effect, stable operation, low investment cost, energy saving and environmental protection, and is widely used in various stone and mineral processing plants.

First, the working principle of sand making machine equipment At present, most sand making machines adopt gravel technology combining hydraulic drive and automatic unloading. According to the actual use and operation of customers, innovation is made on the basis of traditional sand making principle. After the sand maker starts to work, the material to be crushed enters the crushing cavity from the feed inlet, and is divided into two parts by the powder feeder. One part enters the impeller rotating at high speed, which is driven by the impeller to accelerate rapidly, and then the material is thrown out from three evenly distributed flow channels of the impeller at high speed.

Firstly, materials and free-falling materials are impacted and crushed, and then they collide with the material lining layer in the vortex branch cavity together, bounced by the material layer, obliquely hit the top of the vortex cavity, and form a material curtain with the materials thrown by the impeller in turn, and the materials are collided, rubbed and ground at least twice or even more in the crushing cavity until they are crushed.

Second, the advantages and characteristics of the sand making machine 1, the sand making machine has advanced structure and reasonable technology.

The crushing technology of the new sand making machine adopts imported high-quality alloy forging combined throwing head to replace the traditional integral hammer head and square impact block, making the throwing head hard, tough and high temperature resistant. The new principle of sand making machine improves the original workflow, makes the whole process more rigorous and reasonable, not only improves the equipment efficiency and finished product quality, but also saves electricity.

2. The sand making machine has long service life and is more environmentally friendly.

During the whole sand making process, materials collide, grind and break, and do not directly contact with metal parts, which reduces the probability of material pollution and deterioration and prolongs the service life of equipment. The improvement of the crushing chamber also skillfully circulates the airflow itself, reducing the possibility of dust pollution and being more environmentally friendly.
