sand making machine-roll crusher

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.

The advantages of sand making machine

图片
Vsi sand making machine First of all, said the design advantages: the flexible design of sand making machine makes the stone crusher more convenient to maintain and improve his life. It can be said that this is Tarzan machinery combined with the customer's actual feedback, after years of work accumulated research and development out. 1.Tarzan's vertical shaft impact crusher using high-speed, heavy, closed rotor. 2.In addition, the company also designed deep cavity rotor optimization, so that the material through the volume increased by 30%. 3.Modular design of the hammer, just when worn wear parts, it can reduce the cost of more than 30%.

Working principle of sand making machine

图片
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...

The development direction and market potential of gravel production line

图片
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...
