Hammer crushers are designed to crush materials by the impact of a high-speed rotating hammer on the material. They are commonly used in the mining, cement, coal, and metallurgical industries to crush materials such as limestone, gypsum, coal, and other minerals.
If you want to round the shape of stones using a hammer crusher, you can adjust the gap between the hammer and the impact plate to control the size of the material being crushed. By adjusting the gap, you can control the degree of crushing, which can lead to a more rounded shape.
However, it's important to note that the shape of the crushed stones will also depend on the initial shape and size of the material being crushed. If the stones are irregularly shaped or have sharp edges, it may be more difficult to achieve a perfectly rounded shape using a hammer crusher.
Additionally, it's important to consider the type and quality of the hammer crusher being used. Different crushers may have different capabilities when it comes to shaping the material being crushed.
