Sand making machine, sand maker, sand maker price

VSI sand maker, which can also be called VSI series vertical shaft impact crusher, is a high-performance sand making machine with international advanced level and it is researched and manufactured by our company on the basis of introducing Germany advanced technology. It plays an indispensable role in the fine crushing of all kinds of ores due to its outstanding performance. Sand maker has two working principles: stone impacts stone and stone impacts iron, the former is suitable for processing the materials with strong abrasive property and the latter is suitable for processing with weak abrasive property, and the sand making rate of the latter is 10-20% higher than that of the former.
Working Principle:
The materials go into the crusher from the feed hopper and are separated into two parts by the distributor. One part goes into the impeller rotating with high speed from the middle of the distributor, and is quickened inside the impeller, and the acceleration can reach hundred times of the acceleration of gravity, and then the materials will cast from the three uniformly distributed runners of the impeller at a speed of 60-70m/s, and impact and crush with the other part of materials which fall from around the distributor and then they will together impact to the material lining inside the vortex cavity. Bounced from the material lining, the materials will impact obliquely upward to the top of the whirling motion chamber which will change their movement direction again, so that materials will move down, and the materials launching from the runners of the impeller will form a continuous material curtain. In this way, the materials will get two times or more hitting, friction, grinding and crushing effect inside the whirling motion crushing chamber. The crushed materials will be discharged from the bottom discharging mouth. This process will form a closed-circuit system together with the cyclic screening system and generally speaking, after three times of cycle, the materials will be crushed below 20Moh. In the whole crushing process, the materials impact and crush with each other without directly contacting the metal spare parts, and just impact and grind with the material lining to be crushed, thus extending the abrasion time of the crusher machine. The ingenious airflow self cycle inside the whirling motion chamber eliminates powder dust pollution.
Applications:
1. Artificial sand making of river pebbles, rocks (limestone, granite, diabase, basalt, andesite), ore tailings, stone scurf, etc.
2. The production of construction aggregates, highway road fabric, cushion materials, asphalt concrete and cement concrete aggregates.
3. The production of mechanical sand used in water conservancy and hydropower, highway, highway, railway, passenger dedicated line, bridge, airport runway, municipal engineering and high building constructions of the engineering field.
4. The preceding process of ore grinding in mining industry; the crushing of materials in building materials industry, metallurgy industry, chemical industry, mining industry, cement industry, refractory material industry, abrasive and other industries.
