The working principle of PFL vertical plate hammer composite crusher is as follows:
After the material falls from the feeding hopper into the cylindrical body, it is firstly impacted by the hammer on the first rotor, and is thrown at a very high speed along the tangential direction of the rotor to the counterattack plate to produce an impact, and the material is inclined on the counterattack plate. Under the action of the tooth surface and gravity, it rebounds to the direction between the outer circumference of the rotor and the counterattack plate (ie, the crushing chamber). The material is again impacted by the hammer that is rapidly rotating and then thrown to the counterattack plate, and the process is repeated. . As the material is subjected to the repeated impact of the plate hammer and the counterattack plate in the crushing chamber and the mutual impact between the blocks, the material is broken along the inside of the natural section and inside the layer. When the particle size of the crushed material is smaller than the discharge gap of the first-stage rotor, the material enters the crushing cavity of the second-stage rotor under the action of gravity. The second stage crushing process is the same as the first stage, except that the linear speed of the second stage rotor is higher than that of the first stage, and the impact of the material is greater, so that the material can be broken more finely. When the material is broken down to the final product size, it is discharged from the discharge hopper. The larger type generally has three stages of crushing and has three rotors.
The working principle of the PFL vertical plate hammer composite crusher is to use the hammer impact and extrusion to break the material.
The crushing process of the PFL vertical plate hammer composite crusher is broken by the type. The general material is added from the feed port to the finished product, and only 2~3s in the crushing chamber. Therefore, the throughput of materials is relatively fast and the output is high.
The PFL vertical plate hammer composite crusher combines two methods of crushing materials into one body. The first level of crushing reflects the characteristics of the counter crusher, and the large piece of material is broken by high-speed impact to become a small block. The second-stage pulverization also reflects the characteristics of the extruder. After the small piece of material is impacted and crushed, it is broken, and the product becomes powdery and small-grained material; the broken material is rotated in the body to make the material full. The material is crushed and squeezed in the second crushing chamber, and the crushing strength can reach 30 MPa, and the particles are laminated, and at the same time, the impact crushing the particles. Thus, the material discharged under the action of impact and extrusion is not a cake, but a loose body of the material. Therefore, the products of the vertical plate hammer composite crusher do not need to use the scattering equipment.
Vertical plate hammer composite crusher performance characteristics:
(1) The crushing ratio is large, the maximum feeding particle size is 100~220mm, and the discharging granularity is less than 3mm, accounting for more than 90% (30%~60% of which is powder), the discharge granularity modulus is adjustable, and stone material shaping can be done. The straight-through type does not require a purlin, and the wet material is not easy to block the material;
(2) High energy utilization rate, power consumption per unit of output is 1.29 KW?h/t;
(3) Used in conjunction with the ball mill , the mill output can be increased by 30%~40%, and the system power consumption is reduced by 20%~30%;
(4) Less wearing parts, high wear-resistant alloy material for wearing parts, low wear and long service life;
(5) Balanced operation, good sealing performance, less dust and low noise;
(6) The structure is simple, the operation is convenient, the floor space is small, and the installation and maintenance are convenient.
