Sand maker can also called sand making machine or vertical shaft impact (VSI) crusher, is one kind of high-energy and low-consumption impact crusher with the international advanced level, its performance in all kinds of ores fine crushing equipment plays an irreplaceable role, FTM sand maker is the most effective, practical and reliable stone crushing machine currently. The sand maker adopts the ‘stone hit stone’ principle, and this equipment is widely used in construction, water conservancy and electric power industries. It is suitable for gravel, pebbles, granite and other materials. This passage briefly introduces the structure, application, advantages and maintenance method of sand maker.
1.Sand maker is generally made of feed inlet, distributor, vortex crushing cavity, impeller and spindle.
2.The sand maker is widely used in metal ore, non-metallic ore, cement, refractory materials, glass raw materials and construction aggregates; At the same time it is also used in the artificial sand making of the ore tailings and stone chips, in some aggregates production, such as road fabric, cushion material, asphalt concrete and cement concrete, as well as in the fine crushing and coarse grinding of a variety of metallurgical slag.
The outstanding advantage of sand maker
1.The vertical shaft impact crusher is more superior than other types of crusher in crushing these materials, such as silicon carbide, emery, sintered aluminum vanadium and magnesia, etc.
2.Its structure is novel, unique and simple.
3.It has high yield and big crushing ratio.
4.The equipment is small in size, convenient in operation, installation and maintenance.
5.The equipment has the shaping functions, the finished product is cubic, the stacking density is large
Material requirements for sand maker
1. Material hardness: Generally speaking, the harder materials are not easy to make in the process of sand making, which is more likely to have the relatively large damage degree of the sand maker and cause the destruction to the machine.
2. Material viscosity: The greater the viscosity of the material, the easier it is to adhere to the machine. The material with high viscosity will adhere to the inner wall of the sand maker’s chamber, if not timely, will affect the sand maker’s work efficiency, may also seriously affect the normal work of the sand maker. Therefore, in the choice of materials, it is important to note that the viscosity of the material is not too large.
3. Material humidity: When the moisture content of the material is large, the material is easy to adhere to the inner wall, which can easily cause blockage during the material feeding process, resulting in the decrease of the sand making capacity. So we should strictly control the material humidity in the choice of material, if the choice of material humidity is too big, we can use sunlight dry, wind dry or other ways to reduce moisture in the material, it will greatly reduce the impact on the sand maker.
