Machine-made sand with a well-shaped grain can enhance concrete performance, minimize material waste, broaden its applications, and increase market value. So, which type of crusher produces high-quality machine-made sand? And how can we optimize the grain shape of our output for better results?
The quality of the grain type is not only related to the type of crusher but also closely tied to the parameter settings and process combinations. We believe that with careful adjustments and thoughtful consideration, we can achieve optimal results together. When selecting the type of crusher, it is recommended to consider choosing an impact crusher, such as an impact crusher or an vertical shaft impact sand making machine. The impact crusher creates cubic particles through impact and multiple collisions, whereas extrusion-type crushers (like cone crushers) tend to produce elongated and flaky particles. Additionally, factors such as the crushing ratio, feed size, and cycle load are also important considerations.
impact crusher (better grain type)
Granular characteristics: The final product has a cube-like shape with smoother edges, a flat surface, high powder content, and a lower proportion of needle-like and flake particles.
Technical advantages: By combining the synergistic effect of impact crushing with a multi-stage impacting plate, both the crushing and shaping processes can effectively enhance the material’s grain shape, leading to optimized results.
Application field: It is suitable for medium and low hardness (such as limestone, coal gangue) and the processing of brittle materials, also suitable for building materials, sand aggregate and more.
Vertical impact crusher (optimum grain type)
Grain characteristics: The final product comes in a cube shape, featuring an attractive grain pattern, minimal needle-like content, and a low amount of powder.
Technical advantages: It features two stone-beating modes, and the double-rotor design enhances crushing efficiency while reducing needle-like particles. By adjusting the gap of the impact plate, it controls the particle collision angle, optimizes the uniformity of particle shape, and makes the particles more rounded. This is ideal for the production of Class I sand.
Application field: It is perfectly suited for fine sand making and shaping of materials with any hardness level. Ideal for applications in construction materials, premium highway aggregate production, and other fields where strict grain type requirements are essential.
Cone crusher
Granular characteristics: The finished product features more needle-like particles, prominent edges and corners, and less regular grain structure. To achieve higher standards, it would benefit from additional shaping processes.
Technical reasons: By applying the principle of extrusion crushing, the material is gently compressed and crushed multiple times under pressure between the mantle and concave. While this process effectively breaks down the material, it may naturally lead to the formation of irregular grain shapes.
Application field: Dedicated to large-scale crushing of high-hardness materials (such as granite and basalt), this equipment is ideal for mining fields where grain shape requirements are not too strict. To achieve an excellent grain shape, you may consider adding a vertical shaft impact crusher (sand making machine) after the cone crusher to refine the material.
