Coarse crushing of river pebbles is the first important link in the river pebble sand-making production line. Its purpose is to crush large river pebbles into smaller particles for subsequent medium and fine crushing and sand-making operations.
Equipment selection for coarse crushing: jaw crushers or impact crushers are usually used for primary crushing.
Jaw crushers: such as PE series jaw crushers, which can crush high-hardness river pebbles, have large local pressure, thick jaw plates, large jaw tooth spans, large crushing bending moments, and narrow and deep jaw openings, which are suitable for coarse crushing operations.
The purpose of medium and fine crushing is to further crush the river pebbles after coarse crushing to smaller particle sizes to meet the needs of subsequent sand-making operations.
Equipment selection for medium and fine crushing: cone crushers or impact crushers are usually used for medium and fine crushing.
Cone crusher is one of the commonly used equipment in medium and fine crushing of river pebbles. It adopts the principle of laminated crushing and has the advantages of a large crushing ratio, high crushing efficiency, low energy consumption, and uniform product particle size. The cone crusher is suitable for crushing materials of medium hardness and above and can handle river pebbles of various hardness.
The purpose of sandmaking is to further process river pebbles after coarse crushing and medium and fine crushing into sand that meets the requirements.
Sand making equipment selection Sand-making machine: Commonly used sand-making machines include impact sand-making machines, high-efficiency fine crusher, etc. This equipment can further crush and shape the river pebbles after medium and fine crushing to achieve the required sand specifications.
The shaping mechanism inside the sand-making machine will shape the crushed particles to make their shape more regular and uniform.
River pebble sand washing operation is one of the key steps in the river pebble sand-making production line. The main purpose is to remove the soil, sticky substances, and other impurities on the surface of the sand and improve the purity and quality of the sand and gravel.
Sand washing equipment selection Sand washing machine: Commonly used sand washing machines include wheel bucket sand washing machines, spiral sand washing machines, etc. This equipment effectively removes the soil and impurities on the surface of the sand by water flushing and screening.
Inside the sand washing machine, the sand is mixed with water and washed by the water flow. By adjusting the intensity and angle of the water flow, you can ensure that the sand is fully cleaned.
