Henan DEWO four suggestions for reforming hammer crusher
Hammer crushers are used to crush medium-hard materials such as limestone, slag, coke, coal and other materials in cement, chemical, electric power, metallurgy and other industrial sectors. Hammer crushers are commonly used for crushing limestone, but traditional hammer crushers have certain shortcomings. Today, the Henan DEWO stone crusher machine manufacturer technology department addresses the shortcomings of hammer crushers and combines its use in actual production. Several points are put forward. The improvement opinions help customers better use the hammer crusher equipment. The following is the description of pc1000×800 hammer crusher equipment.
Pc1000×800 Hammer Crusher
1. Overlay welding to reinforce the screen frame and screen bars. After the screen frame and the screen frame are installed and positioned, the wear-resistant surfacing electrode is used to reinforce the screen frame. The surfacing height of the wearable working surface is about 5mm. At the same time, the screen rod is welded and fixed on the screen frame to prevent sieve The bar frame is deformed and the screen bars are scattered, which plays a fixed and protective role. This improvement can greatly extend the use time of the screen frame and the screen rod, and reduce the material consumption.
2. Carry out the hammer crusher rotor dynamic and static balance test, install the strike balance hammer head, this kind of improvement is an important way to solve the hammer crusher vibration. The foundation of the hammer crusher is integrated with the foundation of the drive motor, and concrete masonry is used to enhance its anti-vibration performance and avoid vibration damage to the foundation, thereby ensuring the performance of the Henan DEWO stone crusher machine manufacturer.
3. The screen frame is extended by 160mm, 4 more screen bars can be arranged to increase the work area of the hammer crusher, and the products with qualified particle size can be discharged from the crushing cavity in time, reducing the generation of over-crushing, reducing the load of the stone crusher, and improving the production capacity. .
4. The integral structure of the upper frame is changed to a split structure. This structure makes it very convenient to inspect and repair the rotor. The rotor can be lifted out only by removing the left part of the split part. Attention must be paid during the transformation. When cutting the upper frame and welding a pair of flanges, it is required to remove the stress to ensure the assembly performance of the whole machine. The radian of the screen bar rack R520 is changed to R510, which reduces the gap between the screen bar and the hammer head, and at the same time facilitates the adjustment of the screen bar rack. When the hammer head is worn, the screen bar rack can have enough adjustment positions.
