stone and sand making line: 1. high efficiency 2. enough capacity 3. save electricity
stone and sand making production line which is high-functioned equipment for making sand and shaping, is researched and produced by our corporation, absorbed with the advanced technology from Germany, and owned advanced world standards. This equipment has two types: rock-on-rock and rock-on-iron. Sand yield of “rock-on-iron” type is higher by 10-20% than that of “rock-on-rock” type.
Usages1. It is used for producing building aggregate, concrete, aggregate for road surface and roadbed, asphalt concrete and cement concrete.2. It is also used for sand making and shaping in the field of engineering such as water conservancy, hydroelectric power, high-class highway, high-speed railway, passenger special line, bridge, airport pavement, municipal works and high-rise buildings. 3. It is used widely in many industries such as building materials, metallurgy, chemical engineer, mining, refractory materials, cement etc.4. It is used for producing glass raw materials, quartz sand and other high purity materials.
Working Principle Material falls down into high rolling impeller cavity vertically through the upper part of machine. Under great centrifugal force, it hits and crushes another part of material that distributing around the impeller with umbrella form. After hitting each other, they force a vortex between impeller and shell, and hit each other several times; finally smaller stone comes out, and goes to vibrating screen. Satisfactory material is transported by conveyor belt. However overlarge material will go back to Vertical Shaft Impact Crusher to be re-crushed. Otherwise, output sizes can be also adjusted according to customer’s requirement.
Features and Benefits1. Simple structure, easy to set up and repair, low cost in operation; 2. High production of crushing, has the function of fine crushing and rough grinding; 3. Excellent shape of product, mainly the product shape is cubic with small fraction of elongated flaky particle shape, suitable for aggregate shaping, manufactured sand.4. It is little affected by the moisture content of materials, and the content can get up to about 8%.5. It is suitable to crush medium hard and ultra-hard materials. 6. Working noise is lower than 75 decibel, less dust pollution.
Main equipment
1) Jaw crusher
jaw crusher is usually used as primary crushing during the stone or sand processing , because it's high capacity , large opening and durable wearing parts, it's easy to maintain
2) Impact crusher
impact crusher can be used as secondary crushing, it's the ideal choice for making building material, for it's finished mateterial with cubic shape and without interior cracks
3) Cone crusher
cone crusher is widely used for the secondary crushing, because it's reliable working condition, but it's not easy to maintain if there is problem
4) Fine crusher
fine crusher is also called second generation sand making machine, it has high efficiency, can produce fine material , average size less than 5mm. it also widely used before ball mill during the mineral selecting processing.
5) Vibrating feeder and screen
they are necessary equipment during the sand or stone making processing. feeder is mainly used for well-proportioned sending raw material to jaw crusher, meanwhile, it can screen material primary. the screen is made according to the kinds of finished material
Special design for sand and stone production line
