Pick the Right Crusher Double Efficiency Halve Costs

Crushing equipment stands as the core machinery in manufactured sand production. Its proper selection and process configuration exert a decisive impact on finished product quality, production efficiency and operational costs. Varying in working principles, structural features and application scopes, different crushing equipment undertakes primary, secondary, fine crushing and particle shaping respectively in the production line, transforming raw rock into qualified manufactured sand. This article systematically elaborates on the application of major crushing equipment, including jaw crusher and vertical shaft impact crusher, in manufactured sand production.

Functions: As the primary crushing equipment in the production line, the jaw crusher utilizes the squeezing and splitting action between the moving jaw and fixed jaw to initially crush large-sized ores (such as granite, basalt, river pebbles, etc.). Jaw crusher typically reduces the feed material to a particle size range of 10–350 mm, providing appropriately sized raw materials for subsequent secondary and fine crushing processes that often involve other crushing equipment or the vertical shaft impact crusher.

Equipment Features: The jaw crusher boasts a simple and reliable structure, strong adaptability, and low maintenance costs, making jaw crusher particularly suitable for primary crushing of high-hardness materials. However, drawback of the jaw crusher is the high proportion of flaky and needle-like particles in the output, which usually requires improvement through subsequent crushing or shaping processes using specialized crushing equipment like the vertical shaft impact crusher or dedicated sand making machine.

Functions: The vertical shaft impact crusher, commonly known as the VSI sand making machine, adopts the "rock-on-rock" or "rock-on-iron" crushing principle. This crushing equipment accelerates materials through the rotor and hurls them into the crushing chamber, where high-speed collisions trigger self-crushing and shaping. It produces high-quality manufactured sand with a particle size of 0–5 mm, characterized by rounded grain shape, well-graded distribution, and low flaky/needle-like particle content, meeting national standards for construction sand.

Equipment Features: The vertical shaft impact crusher, a key sand making machine, integrates sand making, shaping, fine crushing, and primary grinding functions. This crushing equipment delivers high sand yield, excellent product grain shape, and compact system configuration, making it one of the core crushing equipment for producing premium manufactured sand.
