sand making machine

Advantages of High Effective Fine Impact Crusher (1). Peculiarity: The new type high efficiency and energy-saving sand making machine of the third generation has the special structure, counter-attacks liner flat hammer with high chromium which can adjust the particle size and simplify the procedure. (2). High efficiency: The new types sand production rate is more than the traditional impact sand machine about 40-60%. (3). Power saving: The new type machine can save electric 50 to 70% which is more than the traditional sand machines. (4). High quality: The finished product of sandstone with cubic shape has the strong ability of anti-pressure which is applied to the high-standard architecture. (5). Save money: The new type machine can save money 50-60% than traditional one. (6). Maintenance: The new type machines maintenance ratio is lower 50-60% than traditional ones.

Production Description The Hydraulic Roller Crusher product is applied to crushing various medium hardness materials such as limestone, slag, coal etc. in metallurgy, cement, chemistry and other industries for primary and secondary crushing. Top long industrial miner equipment double teeth roll crusher Advantages and features 1 Compact structure, low noise and efficient 2 Adjusting the pressure and size easily 3 Low cost maintenance and easy to maintain 4 Easy to install and only need simple foundation 5 Self-production, the parts can not be damaged when hard materials such as metals goes into the crushing cavity.  

Principle of double roller crusher The two rollers have wedge or gasket adjusting device, wedge device with the top adjustment bolt, when the adjustment bolt wedge block upward pull up, wedge will activities roller top from fixed wheel, two roller gap becomes larger, the discharge size becomes larger, when the wedge block down, activity roller compression spring (or pressing oil cylinder) under the action of two gap becomes smaller, the discharge size becomes smaller. Gasket device is through increase or decrease the number of gasket thickness to adjust the size of the discharge size, when adding gasket will make two roller wheel gap bigger, when reduce gasket will make two roller wheel clearance decrescent, the discharge size becomes smaller .

Working principle of sand making machine The materials enter the crusher through feeder hopper, which is divided into two parts, one part through the middle of classifier entering into the rotating impeller at high speed, then accelerated, whose speed can reach hundreds of acceleration, then is shot through the tunnels around the impeller by the speed of 60-75 meter/second. First the materials will impact with some materials fallen around classifier, then impact on the whirlpool cavity's scale board together, then will be rebounded and impact on the top of the whirlpool cavity, then changes its direction and goes down, forms continual material layers with the materials shot from the impeller. Therefore some materials will be impacted, crusher, milled twice or more times in the whirlpool cavity, then crushed materials will be excluded through the bottom discharging hole. This can from a closed circulation through the circular classifier system; in general, materials can be crushed i...

Material crushing on the gravel production line is a widely used process in the industrial sector, where a large amount of raw materials and recycled waste are required to be crushed every year. About 15% of the world's electricity is consumed in the crushing industry, gravel crushers and are increasing year by year. The principle of crushing and grinding is that it is an important way to improve the efficiency of grinding and reduce the cost of selection. After years of practice and summary, gravel crusher crushing area is vigorously promoting the "more broken less grinding" process, that is, to reduce the final size of broken products, increase the fine-grained in the crushing of the product content, thereby enhancing the processing capacity of equipment , To reduce power consumption and metal consumption, reduce costs and increase the cost of economic purposes. This makes the gravel production line to the crushing, energy efficient direction. In addition, the importanc...

Double teeth roll crusher suitable for compression strength less than 240MPa, humidity less than 35% of the hard and soft materials, primary operations in the intermediate and coarse crushing. Such as  coal, coke petroleum coke, lime, silica, glass, asphalt, chemical raw materials or solid material with similar hardness. Features: low use and maintenance costs, high reliability, low dust, low noise. working principle Double teeth roll crusher is fixed with two wear-resistant alloy rolls. Their relative rotation generates high extrusion pressure which crushes the material. The material enters into the space between the two rolls, suffered both extruding and shears force. In the crowd rolling, cutting and grinding, it is crushed into the required size and then sent by the transport equipment.
