Regardless of incoming material processing or mining processing, a set of sand making machines mainly includes crushing, sand making, screening, and transportation. At the same time, it can also be equipped with sand washing equipment after sand making, aiming at high requirements and high standards of sand demand. The selection of the situation; among them, the crushing equipment and sand making equipment are the key machines for making sand from stone, and the production is configured according to the output demand.
Sand production line
1. Crushing equipment:
The choice of primary crushing-jaw crusher; it is specially used to crush wet materials with various hardness and different sizes; it has the advantages of more crushing and less grinding, small footprint, deep crushing cavity and large feeding port; The crushing effect of the stone is achieved by pressing and the two jaws are engaged with each other; the shape is designed with a sealed structure to prevent the possibility of splashing during the crushing of the stone, and the dust output is less during operation; the output has the advantage of being adjustable, and the coarse crushing The final stones of various specifications can be completed according to the standard.
Two-stage crushing option-impact crusher/cone crusher; impact crusher is more suitable for crushing medium-hard stones. The main feature is that the discharge needle has less flakes and the finished product has a good grain shape. After screening, it can be used directly. for sand making;
The cone crusher is suitable for crushing stones with relatively high hardness, such as common cobblestones, river pebbles, etc.; it has the advantages of large crushing ratio, high output, and multi-cavity crushing. It uses the principle of laminated crushing to crush stones with high hardness. When stones or foreign objects that are difficult to break are encountered, it can automatically stop to ensure the stability and safety of the equipment.
2. Sand making equipment:
The VSI sand making machine adopts dual-motor configuration operation. It has the advantages of stone sand making and stone shaping. The output particle size is uniform, the needle shape is less and the stone powder content is low. It is the main equipment choice for artificial sand making at present; combined with the characteristics of stone processing The two crushing principles of stone-on-rock or stone-on-iron realize sand making operations.
