Double stage crusher

Product description

Double stage crusher cooperates with trommel screen, which is a common technology for crushing coal gangue in brick factories. After the first crushing of double stage crusher, the discharging granularity of material less than 3MM can reach about 80%. But because bricks require high fineness of coal gangue, so often customers will say, the finer the coal gangue broken, the better. This will have to go through the second crushing, that is, the first broken coal gangue is transported to the trommel screen through the conveyor, does not meet the fineness of coal gangue back to the double stage crusher for the second crushing, so the problem is solved.

 

 

The double stage crusher can crush common materials such as coal gangue, shale, coal gangue, slag, cement, river pebbles, iron ore, limestone, etc. More than 500 construction industries and other industry materials.The machine is equivalent to two hammers broken into one, reasonable combination into one whole, two sets of rotors are used in series, with the following characteristics:

the double rotor up and down two-stage crushingThe two sets of rotors connected in series make the hammer of the lower rotor which is crushed by the hammer of the upper stage immediately crushed again by the hammer of the lower stage which is rapidly rotating, and the materials of the inner cavity collide with each other in a reverse direction and pulverize each other to reach the hammer powder and material. The effect of the powder is directly discharged.

there is no screen bottom, high humidity materials, never blockThe traditional crusher with sifting sieve is not suitable for raw materials with water content higher than 8%. When the moisture content of raw materials is higher than 10%, it is easy to cause serious blockage, so that the hammer can not rotate, the material

Sand Production Application

In sand production lines, the double-roll crusher functions as a sand-making machine, offering advantages such as no wear parts, low maintenance costs, adjustable sand particle size, high yield rate, and excellent sand particle shape. It is widely used in the sand-making industry.

Mineral Processing Crushing Applications

In the mineral processing industry, double-roll crushers or high-pressure roller mills are employed for fine crushing operations. Positioned upstream of ball mills, they can reduce 2-3 cm ore particles to less than 1 mm, significantly enhancing the operational efficiency of mineral processing ball mills and boosting overall production productivity.    

Double rotor up and down double stage crusher: The raw materials enter the crushing chamber from the feed port. The first group of hammers turn downward counterclockwise to beat the materials and smash each other to achieve the effect of hammering powder and powder. Then, the second group of hammers repeatedly beat the materials, and the two groups of hammers beat the materials at high speed.
