Double rotor sand making machine

Description

Double rotor sand making machine is referred to as double rotor sand making machine, suitable for limestone, blustone and other raw materials crushing operation, the gap between the grate and the hammer can be flexibly adjusted, the particle type into a cube, the particle grading and the degree modulus are more suitable for the requirements of commercial concrete concrete mixing station, widely used in commercial mixing station, stone factory, cement factory, phosphate fertilizer factory, ceramics factory and refractory material factory. Feed<250mm, not only can be used for pure handle sand, but also for sand and stone (Laibe shaping function), the finished product size can be flexibly adjusted (the grate gap can be customized). When the output of 150-300 tons model complete, can be customized.

Performance Advantages

• 1, double rotor structure, single large output: the relative operation of two rotors to drive the crushing chamber material impact with each other, the use of "stone beating stone" principle to form the self-crushing of stone in the crushing chamber, greatly reducing the hammer head, wear ring and other wear, life increased by 45%. When the kinetic energy of the dual-rotor structure is sufficient, the minimum output is 150 tons, and the large one can reach 300 tons.
• 2, full hydraulic open, internal parts replacement and maintenance fast and convenient, greatly shorten the maintenance time;
• 3, the equipment is equipped with observation doors around the equipment, easy to observe the internal situation of the equipment at any time, repair and maintenance is faster and more convenient;
• 4, the rotor is attached with high manganese and high chromium protective cover, the life is increased by 30%;
• 5, the sea shaft hole is equipped with tungsten alloy hairpin sleeve, more wear resistance, impact resistance;
• 6, grape bar can be customized according to demand, there are round hole grate and long grate optional:
• 7, the gap between the grate and the hammer can be flexibly adjusted to fully ensure the crushing efficiency of the hammer;
• 8, the finished grain shape is a cube, the particles are round, grade continuous; The fineness modulus is adjustable.

Working Principle

When the material enters the sand making machine, it passes through the dividing counter device, and the material is evenly distributed above the two rotors. The two rotors rotate relative to each other, and the material gains kinetic energy under the blow of the hammer head and flies to the other rotor. Therefore, the materials on the two rotors collide in the direction of the rotation tangent of the rotor, and the dividing counter device is directly above the collision point. Under the action of the counter plate, the first "stone beating stone" crushing and corrugated groove shaping are completed. By the kinetic energy of the rotor, the material continues to rush downward towards the anvil to achieve a second crushing, and the stepped surface of the anvil is shaped twice. The anvil and the grate form an arc transition, after the second crushing and shaping of the material in the hammer head driven by the average distribution of the anvil into the rotor and the grate composed of two fine fragmentation area, this area is the key area of fine fragmentation into sand, in the hammer head high-speed impact and formed under high pressure, the material is broken and discharged grate. At the same time when the material is discharged from the grate, due to the stepped channel of the grate, it is shaped again, and the material particles that are suitable for the grate size are discharged through the grate and become the machine sand, and the material particles that are not in line with the size continue to be taken to the two rotors to continue to break.
