VSI vertical shaft impact Sand Making Machine, also known as fine crusher, is a new generation of impact sand making machine suitable for Chinese customers, developed by introducing German sand making technology and combining with my country's working conditions. Compared with products of the same type, it has high output, good grain shape and low cost of use.

VSI Impact Sand Making Machine

VSI sand making machine is the latest type of sand making machine, which can save 50% energy than traditional sand making machine. It can make all kinds of rocks, gravels and river pebbles into construction sand with various particle sizes. The sand has uniform particle size and high compressive strength. requirements to improve the quality of the building. The equipment has the characteristics of reliable performance, reasonable design, convenient operation and high work efficiency.

Scope of application of VSI impact sand maker

VSI sand making machine is mainly used for building sand making, and it is an advanced equipment for producing artificial sand. Equipment in the field of artificial sand making and stone shaping. Usually, it can be combined with sand washing machine, crusher, vibrating screen, vibrating feeder, etc. to form a sand making line for more economical and efficient production.

VSI impact Sand Maker

  • 1. Artificial sand making of river pebbles, mountain stones (limestone, granite, basalt, diabase, andesite, etc.), ore tailings, and stone chips.
  • 2. Production of building aggregates, road fabrics, cushion materials, asphalt concrete and cement concrete aggregates.
  • 3. Water conservancy and hydropower, high-grade highways, expressways, high-speed railways, passenger dedicated lines, bridges, airport runways, municipal engineering, and high-rise buildings in the field of water conservancy and hydropower production and stone shaping.
  • 4. Fine crushing process before grinding in the mining field, material crushing in building materials, metallurgy, chemical industry, mining, refractory materials, cement, abrasives and other industries.
  • 5. High abrasiveness and secondary disintegration and crushing, desulfurization in thermal power and metallurgical industries, and environmental protection projects such as steel slag and construction waste crushing.
  • 6. Production of glass, quartz sand and other high-purity materials.

How VSI impact sand maker works

VSI sand making machine is to use high-speed rotating materials to crush each other and friction between materials to crush (stone hits stone). Crusher. The maximum water content of the crusher is less than 20%. Generally, the ore from the sand washing machine can directly enter the machine for crushing.

VSI impact Sand Maker

The output particle size of the VSI sand making machine is related to the physical properties of the ore and the input particle size. The ore is fragile, and the smaller the input particle size, the higher the qualified rate of the product particle size.
Conversely, the lower it is, the smaller the impeller speed is, the product particle size can also be adjusted. When the particle size of the output product of the sand making machine is not greater than 10mm, the qualified rate is 60-90%. In order to ensure that the qualified rate of the product particle size reaches 100%, it is necessary to use grading equipment for closed-circuit crushing.

Product features of VSI impact sand maker

  • 1. Large processing capacity and high output - 50-500t/h, compared with traditional equipment with the same power, the output is increased by 30% and is stable.

    2. Low consumption of wearing parts - optimal design of the impact angle of materials in the crushing cavity, less friction with wear-resistant parts, 30% lower operating cost than traditional equipment, which directly reduces the cost of equipment use.

  • 3. The product has excellent grain shape - the product is cubic, with good grain shape, reasonable gradation, and adjustable fineness modulus; it is especially suitable for artificial sand making and stone shaping.
  • 4. Hydraulic device, easy maintenance - hydraulic cover opening device makes the repair and replacement of the components in the crushing chamber convenient and quick, shortens the downtime, saves time and effort.
  • 5. Automatic detection, safe and reliable - set up over-vibration display and alarm devices, if the equipment is in bad operation, it can issue a warning to stop the equipment from working and achieve the purpose of protecting the machine.
  • 6. Thin oil lubrication and automatic maintenance - German original thin oil lubrication station, double oil pumps complement each other to ensure oil supply, automatic shutdown when there is no oil flow and no oil pressure; oil cooling and heating devices ensure that the bearing lubrication is always in the best state. So as to completely solve the problem of bearing heating, keep the main shaft bearing at a constant temperature, and prolong the maintenance cycle and service life.
  • 7. Simple installation and easy operation—the equipment is light in weight, has various installation methods, and can be installed in a mobile manner; installation, repair and maintenance are simple, and operation and use are convenient; maximize its excellent performance.

Operating procedures of VSI impact sand maker

  • 1. Check whether the observation door of the vortex chamber is closed tightly before starting to prevent the material from rushing out of the observation door of the vortex chamber, which may cause danger.

  • 2. Check the rotation direction of the impeller, looking from the direction of the feed port. The impeller should turn counterclockwise, otherwise the motor wiring should be adjusted.
  • 3. The starting sequence of the crusher and conveying equipment is: discharge→crusher→feeding
  • 4. The crusher must be started with no load, and the material will be fed after the crusher runs normally. The shutdown sequence is the opposite of the startup sequence.
  • 5. When the discharging equipment stops, the feeding should be stopped in time, otherwise, the impeller will be crushed and the motor will be burned.
  • 6. The feeding should be continuous and uniform.
  • 7. During the operation of the crusher, there should be no violent vibration and abnormal noise, otherwise, it should be stopped for inspection.
  • 8. The lubrication of the machine is dry oil lubrication. Mobil vehicle grease is used. The amount added is 1/2-2/3 of the bearing cavity. When the crusher works for each shift, add an appropriate amount of grease to work. After several shifts, open the main bearing to clean the main bearing, and replace the bearing if necessary.
