Right Sand Making Crusher Doubled Efficiency and Halved Costs

Application Stage: Primary Crushing

Jaw Crusher

Function of jaw crusher: As the front-end primary crushing equipment, jaw crusher crushes large-size raw ores (granite, basalt, river pebble, etc.) via squeezing and splitting force between the movable jaw and fixed jaw. Jaw crusher generally reduces raw materials to particle sizes ranging from 10-350 mm, and jaw crusher prepares feed material with suitable dimensions for follow-up processing by cone crusher, impact crusher, VSI crusher(VSI sand making machine) in subsequent secondary and fine crushing procedures.

Features: Jaw crusher boasts a simple and sturdy structure, strong adaptability and low maintenance cost, making jaw crusher ideal for primary crushing of high-hardness materials. jaw crusher's main drawback lies in a high proportion of flaky and needle-shaped particles in discharge from jaw crusher, which requires further crushing or shaping by cone crusher, impact crusher, VSI crusher or VSI sand making machine in follow-up processes.

Application Stage: Secondary & Fine Crushing

Cone Crusher

Function: Adopting laminated crushing principle, cone crusher further crushes materials discharged from jaw crusher through repeated extrusion and bending between the moving cone and fixed cone. Cone crusher is capable of secondary crushing (discharge size: 3–60 mm) and fine crushing (discharge size: below 30 mm); cone crusher features high crushing efficiency and well-distributed particle gradation. The cone crusher supplys intermediate materials with proper granularity for the downstream VSI crusher and VSI sand making machine’s sand making tasks.

Features: Cone crusher delivers powerful crushing force, stable operation and uniform product particle size, so cone crusher is perfectly suited for secondary and fine crushing of medium and high-hardness materials. Nevertheless, cone crusher demands relatively high capital investment and maintenance expenses, with strict requirements for operation and routine upkeep different from jaw crusher, impact crusher, VSI crusher.

Application Stage: Secondary & Fine Crushing

Impact Crusher

Function: A high-speed rotating rotor drives blow bars to strike materials, and impact crusher achieves crushing via impact and collision meanwhile providing preliminary particle shaping to produce more cubical finished aggregates. Impact crusher is mainly applied to medium and low-abrasion materials such as limestone, coal gangue and gypsum, and impact crusher often works in tandem with jaw crusher, cone crusher before feeding materials into VSI crusher.

Features: Impact crusher has a large reduction ratio and excellent aggregate shape with flexible layout options. However, impact crusher suffers severe wear when processing highly hard or abrasive materials; improper parameter setting for impact crusher may lead to excessive over-crushing that needs correction by VSI crusher.

Application Stage: Sand Making & Particle Shaping

VSI Crusher

Function: VSI crusher, also widely known as VSI sand making machine, operates on rock-on-rock or rock-on-iron crushing mechanisms. VSI sand making machine (namely VSI crusher) accelerates and throws out materials via its rotor to create violent collisions inside the crushing chamber for self-fracturing and shaping. VSI sand making machine(VSI crusher) produce premium manufactured sand sized 0–5 mm characterized by rounded grains, reasonable gradation and low needle-flake content, vsi crusher fully complying with national standards for construction sand after receiving pre-crushed feed from jaw crusher, cone crusher and impact crusher.

Features: VSI sand making machine (VSI crusher) integrates sand making, shaping, fine crushing and coarse grinding functions with high sand yield, superior particle shape and compact system layout. VSI crusher rank as the irreplaceable core machines for high-quality manufactured sand production, complementing jaw crusher, cone crusher and impact crusher perfectly.

Application Stage: Fine Crushing

Function: Materials are crushed through extrusion and shearing between two rollers, with output granularity flexibly adjustable by modifying the roller gap. It is widely used for fine crushing of medium-low hardness materials including limestone, dolomite and crushed stone chips. It effectively restrains over-crushing and improves finished product yield especially when producing small-size aggregates that will later be refined by impact crusher, VSI crusher for final manufactured sand output.

Features: Low energy consumption, simple structure, convenient overhaul and minimal over-crushing. Its processing capacity is relatively limited, so it is mostly deployed in small-to-medium production lines as an auxiliary ahead of impact crusher, VSI crusher for dedicated fine crushing sections for specific materials.

Manufactured sand production is a systematic project, wherein jaw crusher, cone crusher, impact crusher, VSI crusher each fulfill designated crushing and shaping tasks along the process chain. To configure a scientific production line, comprehensive factors shall be taken into account, including material properties (hardness, abrasiveness, moisture content, etc.), required output capacity, finished particle shape and gradation standards, as well as capital and running costs. Only by reasonably selecting and optimizing the combination of jaw crusher, cone crusher, impact crusher, VSI crusher for primary, secondary, fine crushing and sand shaping can manufacturers realize high-efficiency, high-quality and low-consumption manufactured sand production.
