VSI Sand Making Machine is a kind of mechanical equipment which uses high-speed rotating rotor to project and impact materials to achieve crushing. It is mainly used for medium and fine crushing and sand making of medium-hard or high-hard materials (such as granite, basalt, quartz stone, etc.).
Its core feature is the “stone-to-stone” or “stone-to-iron” crushing method, which can produce aggregates or machine-made sand with excellent particle shape and reasonable grading. It is widely used in mining, building materials, transportation, water conservancy and other fields.
Technical Features
1. Excellent particle shape
• The impact crushing principle is adopted, and the finished particles are mostly cubic with low needle-like content, which is particularly suitable for the production of high-standard building aggregates and machine-made sand.
2. High efficiency and energy saving
• Direct kinetic energy crushing reduces energy loss, saves 30%-50% energy compared to traditional crushers, and has a large crushing ratio (up to 1:40).
3. Adjustable particle size
• By adjusting the rotor speed, feed amount or replacing screen plates with different apertures, the output particle size (usually 0-5mm fine sand or 5-40mm aggregate) can be flexibly controlled.
4. Low maintenance cost
• Modular design, key components (such as throwing head, impact plate) are made of high wear-resistant alloy materials, which are easy to replace and have a long service life.
5. Environmental protection
• The closed structure is combined with a dust removal device to reduce dust spillage; the operating noise is lower than that of traditional equipment.
6. Versatility
• It supports two modes: “stone hitting stone” (material hitting material layer) and “stone hitting iron” (material hitting metal impact block) to adapt to different material hardness and finished product requirements.
Application Areas
• Sand making field: produce machine-made sand to replace natural sand for concrete or asphalt mixture.
• Aggregate shaping: Improve the shape of crushed stone particles to meet the needs of high-standard infrastructure such as high-speed railways and airports.
• Ore crushing: processing of fine crushing of metal minerals such as iron ore and gold ore.
Summarize
• VSI sand making machine has become the core equipment of modern sand and gravel aggregate production line due to its advantages of high efficiency, energy saving and high product quality. Its technical characteristics are particularly in line with the trend of strict environmental control and growing demand for high-quality aggregates, and it is an ideal choice for the production of machine-made sand and fine gravel.
