Highlight advantages
The VSI series high-efficiency vertical axis sand making machine is the latest design result of German authoritative experts combined with China's working conditions. It is currently the only high-performance sand making equipment with world advanced level produced domestically. This sand making machine is designed to provide high-quality sand and gravel aggregates for highways, high-speed railways, high-rise buildings, municipal engineering, hydropower dam construction, and concrete mixing plants. It is the preferred equipment for manual sand making and stone shaping. It is the latest generation sand making machine developed by our company with international advanced level. Excellent cost-effectiveness and reliability stand out among similar products. Long term technological accumulation and precision production of modern processing equipment ensure the VSI series new system has a large processing capacity and high output of 50-500t/h. Compared with traditional equipment under the same power, the output has increased by 30% and is stable.
2. Low consumption of vulnerable parts - the optimal crushing chamber material impact angle design reduces friction with wear-resistant parts, resulting in a 30% lower operating cost compared to traditional equipment, directly reducing the equipment's usage cost.
3. Excellent product particle size - the product is cubic in shape, with good particle size, reasonable grading, and adjustable fineness modulus; It is particularly suitable for manual sand making and stone shaping, and has been proven to improve sand making and shaping effects by 30% compared to other traditional equipment.
4. Hydraulic device, easy to maintain - the hydraulic opening device makes it convenient and fast to inspect and replace the components inside the crushing chamber, shortening downtime and saving time and effort.
5. Automatic detection, safe and reliable - equipped with vibration display and alarm devices, if the equipment malfunctions, a warning can be issued to stop the equipment from working, achieving the purpose of protecting the machine.
6. Thin oil lubrication and automatic maintenance - Germany's original thin oil lubrication station, with dual oil pumps complementing each other to ensure oil supply, automatically shuts down when there is no oil flow or pressure; The oil cooling and heating device ensures that the bearing lubrication is always in optimal condition. Thus, it can completely solve the problems of bearing heating, maintain a constant temperature of the spindle bearings, and extend the maintenance cycle and service life.
7. Easy to install and operate - the equipment is lightweight, has a variety of installation methods, and can be installed in a movable manner; Simple installation, maintenance, and upkeep, easy to operate and use; Once the specific purpose is identified, the VSI sand making machine only needs minor adjustments to maximize its outstanding performance.
8. Multi purpose and flexible application - with a unique feed crushing structure and multiple crushing chamber types, it can easily achieve the conversion between "stone to stone" and "stone to iron", thus solving the problem of multi-purpose use of one machine. If you want to change the application of VSI crusher, there is no need for major adjustments, it can adapt to different user needs: manual sand making, gravel shaping, abrasive materials, etc.
9. International Quality Assurance - The latest German technology and advanced riveting technology, as well as the application of sandblasting, rust removal, and painting processes in automotive manufacturing, greatly improve the internal and external quality of the equipment. The core components are all selected from internationally renowned brands (using high-precision TIMKEN rolling bearings) to ensure a low failure rate of the system.
10. Pay attention to environmental protection - sand making equipment has low working noise and no pollution. The unique air self circulation system greatly reduces the external exhaust volume, reduces dust, and is conducive to environmental protection. In addition, the VSI sand making machine is reserved and suitable for installing various specifications of dust removal equipment. The sand machine holds an absolute leading position in the domestic sand making industry.
Working principle
Full center feeding: The material falls into the feeding hopper of the sand making machine, enters the high-speed rotating impeller through the central feeding hole, is rapidly accelerated inside the impeller, and its acceleration can reach dozens of times the acceleration of gravity. Then it is ejected from the impeller at high speed, first colliding with another part of the material that bounces back and falls freely, and then impacting the material lining layer (stone striking stone) or counterattack block (stone striking iron) together. It is bounced diagonally upward and impacts the top of the vortex chamber, changes its direction of motion, deflects downward, and collides with the material emitted from the impeller channel to form a continuous material curtain. In this way, a piece of material is subject to two to multiple probability impacts, friction, and grinding crushing effects in the vortex crushing chamber. The crushed material is discharged from the lower discharge outlet.
