What is a VSI crusher?
VSI sand making machine is the latest sand making machine, which can save 50% more energy than traditional sand making machine. It can make all kinds of rocks, sand, and pebbles into construction sand with various grain sizes. The sand has uniform grain size and high compressive strength, which is far more in line with the construction requirements than natural sand and sand produced by ordinary hammer-type sand beater and can improve the construction quality. The equipment has the characteristics of reliable performance, reasonable design, convenient operation, and high efficiency.
Application Area
1. Artificial sand making of river pebble, mountain stone (limestone, granite, basalt, diabase, andesite, etc.), ore tailings, and stone chips.
2. Construction aggregate, road fabric, cushion material, asphalt concrete, and cement concrete aggregate production.
3. In the field of water conservancy and hydropower, high-grade highway, expressway, high-speed railway, passenger dedicated line, bridge, airport runway, municipal engineering, machine-made sand production, and stone shaping of high-rise buildings.
4. Fine crushing process before grinding in the mining field, material crushing in building materials, metallurgy, chemical industry, mining, refractory, cement, abrasive and other industries.
5. High abrasiveness and secondary disintegration crushing, desulfurization in thermal power and metallurgical industry, steel slag, construction waste crushing, and other environmental protection projects.
6. Production of glass, quartz sand, and other high purity materials.
Working Principle
VSI sand making machine uses high-speed rotating materials to break each other and friction between materials to break. The maximum particle size of its feeding material must be in accordance with the particle size specified in the technical performance parameter table of the machine. It is strictly forbidden for materials larger than the specified particle size to enter the crusher. The maximum water content of the crusher is less than 20%. Generally, the ore from the sand washer can be directly crushed by the crusher.
The discharge particle size of the VSI sand making machine is related to ore physical properties and feed particle size. The ore is fragile. The smaller the feed particle size is, the higher the qualified rate of product particle size is. On the contrary, the lower the impeller speed, the product size can also be adjusted. When the particle size of the discharged product of the sand-making machine is not more than 10 mm, the qualified rate is 60-90%. In order to ensure that the qualified rate of the particle size of the product reaches 100%, it is necessary to use classification equipment for closed-circuit crushing.
Characteristic
1. Compared with the traditional equipment under the same power, the output is increased by 30% and stable.
2. Low consumption of wearing parts – the best impact angle design of crushing chamber material, less friction with wear-resistant parts, 30% lower than the traditional equipment operation cost, directly reducing the use cost of the equipment.
3. 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. The practice has proved that the effect of sand making and stone shaping is 30% higher than that of other traditional equipment.
4. Hydraulic device, easy to maintain – hydraulic cover opening device, makes the maintenance and replacement of parts in the crushing chamber convenient and fast, shortens the downtime, saves time and labor.
5. Automatic detection, safe and reliable – set up the vibration display and alarm device, if the equipment has a bad operation, it can send out a warning, so that the equipment stops working, to achieve the purpose of protecting the machine.
6. Thin oil lubrication, automatic maintenance – Germany original thin oil lubrication station, double oil pump complementary guarantee oil supply, no oil flow, no oil pressure automatic shutdown; oil cooling and heating device to ensure that the bearing lubrication is always in the best state. So as to completely solve the problem of bearing heating, make the spindle bearing keep a constant temperature, prolong the maintenance cycle, and service life.
7. Simple installation and easy operation – the equipment is light in weight, various in installation methods, and can be installed in a movable way; the installation, repair, and maintenance are simple, and the operation and use are convenient; once the specific purpose is clear, the VSI crusher can give full play to its excellent performance with only minor adjustment.
