VSI sand maker, also called VSI crusher, is the major machine for sand making plant. During the crushing process of sand making machine, raw materials hit each other and not hit any metal parts.
Ball mill is the key machine to grind the crushed materials. Ball mill machine is widely used to process cement, silicate product, building material, refractory material, fertilizer, ceramics and glass, etc.
The coal briquetting machine is used to press materials with little water content including coal, mineral powder and refractory matter.
Different ores have different magnetic coefficients. Magnetic separator is just the machine that uses magnetic and mechanical power to separate the ores from mixers.
High pressure grinding mill has high-pressure springs inside, which can improve the grinding powder to 1.2 times higher. If roller ring is worn out, we can adjust the length of springs to keep the grinding pressure.
Sand washing machine is a kind of high-efficient machine, which is produced by fote according to the actual situations of sand industry around the world.
Rotary dryer is one kind of drying equipment, generally used to remove water containing in materials. Most of rotary drum dryer consists of a rotating drum driven by belt, and the hot air around the drum is used to evaporate water.
