Four suggestions for hammer crusher transformation
Hammer crushers are used in the industrial sectors of cement, chemical industry, electric power, metallurgy and other industries to crush medium-hard materials, such as limestone, slag, coke, coal and other materials. Hammer crushers are commonly used for crushing limestone, but traditional hammer crushers have certain shortcomings. Today, the Henan Dewo crusher Machinery Technology Department addresses the shortcomings of hammer crushers and combines its use in actual production. The improvement opinions to help customers better use hammer crusher equipment. The following is the description of pc1000×800 hammer crusher equipment.
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 wear-prone working face is about 5mm. At the same time, the screen rod is welded and fixed on the screen frame to prevent screening 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 frame, and reduce material consumption.
2. Carry out the dynamic and static balance test of the hammer crusher’s rotor and install the strike balance hammer head. This 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 hammer crusher.
3. The screen frame is extended by 160mm, and 4 more screen bars can be arranged to increase the work area of the hammer crusher. 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 crusher, and improving the production capacity. .
4. The integral structure of the upper frame is changed to a split structure. This structure makes it easy 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 frame 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 frame. When the hammer head is worn, the screen bar frame can have enough adjustment positions.
Henan Dewo crusher machine has been committed to the development and development of mining machinery for many years. The crusher has been transformed, especially the effect of crushing limestone is significantly more significant, the utilization rate is increased, the crushing output is increased, and the use time of the screen frame and the screen bar is extended.
