■ Use: This serial of equipment have widely uses, its performance has already reached the international advanced level, and it is the broken stone machine of the most effectual and reliable practical at present, especially is suitable for making abrasive, refractory material, cement, quartz sand, steel sand, stove powder, copper ore, iron ore, auriferous ore, river cobble, concrete material ,pitch material and so on. The thin broken and moderate broken of the fragile supplies is a kind of high-efficient, energy-conserving equipment of broken stone and making-sand. It cans thrift the 50% of energy than tradition, and it is good making-sand equipment in the world at present.

■ Operation principle: Stones are fallen into the rotary table of high speed whirling directly by the top of the machine, under the function of high-speed centrifugal, then come into striking and high density crush with another part target stone around rotary table by umbrella type, after stones attacking each other, can form vortex sport and cause to attack, grit, crush each other between rotary table and chassis, and then discharge from the under part directly. So it can form many times circulations of the closed and reach to the grain size required by sieve equipment controls.

■ Characteristic: 1, This kind of machine is a new-type broken stone equipment in 1990s, and also is modern type in the world at present, it is already replaced the machines of awl breaker, roller machine and model ball mill. 2, Novel structure, unique, balance operating. 3, Little energy consumption, high –output, large broken rate. 4, small volume, easy handling, conveniently installment and maintain. 5, facelift function, cubic shape, large density. 6, During the producing, stones can be formed the protecting ground floor, then can make fuselage no-wearing &tearing and durable. 7, A small piece of being easy to wearing & tearing is made with specially hard wear-resisting material, and its volume is small, light and easy to change fittings.
