100-150 tph Stone Crushing Plant

The selection of the cone crusher is crucial for this production line. For medium-to-high hardness materials such as granite, basalt, and river pebbles, the CS110 multi-cylinder hydraulic cone crusher is recommended. Its layered crushing principle produces aggregates with better particle shape and less needle-like and flaky content, and its iron-crossing protection function provides greater safety. For medium-hardness materials such as limestone, the PYB1200 spring cone crusher is an economical and reliable choice.

Detailed Explanation of Two Classic Process Flows

This production line is flexibly designed and can select from the following two mature process flows based on the final product requirements (pure crushed stone aggregate or containing manufactured sand):

Flow 1: Classic Aggregate Production Line (Suitable for producing multi-grade crushed stone)

This process focuses on producing high-quality multi-grade crushed stone aggregates, with a simple and efficient flow.

Process Flow: Vibrating feeder → Jaw crusher (coarse crushing) → Cone crusher (medium and fine crushing) → Circular vibrating screen (screening and grading) → Finished aggregate bin.

Process Features: Utilizes the classic combination of "jaw crusher + cone crusher," particularly suitable for crushing medium-to-high hardness rocks. Cone crushers produce aggregates with a three-dimensional shape and strong compressive strength, making them excellent raw materials for commercial concrete plants and high-standard projects (such as highways and railway subgrades). The main finished product of this process is crushed stone of various sizes, ranging from 5-40mm.

Process Two: Sand Making and Shaping Production Line (Suitable for producing high-quality manufactured sand and aggregates)

This process adds a shaping and sand making stage to the classic process, enabling simultaneous sand and gravel output and increasing product added value.

Process Flow: Vibrating feeder → Jaw crusher (coarse crushing) → Cone crusher (medium crushing) → Impact crusher (sand making/shaping) → Circular vibrating screen (closed-circuit screening).

Process Features: Secondary crushing and shaping is performed after the cone crusher. The impact crusher utilizes the "stone-on-stone" or "stone-on-iron" principle to further crush and shape small-sized stones, producing high-quality manufactured sand (0-5mm) with a reasonable gradation and rounded particle shape. Simultaneously, it also shapes the aggregate at the next higher level, resulting in a better overall product particle shape and meeting the demands of the high-end building materials market.

Summary and Comparison: Target Product: Process 1 primarily focuses on various grades of crushed stone aggregate; Process 2 can achieve the co-production of crushed stone aggregate and high-quality manufactured sand.

Core Difference: Process 2 adds an impact crusher as a third-stage crushing (sand making) unit.

Selection Basis: If the market demand for manufactured sand is strong, or if there are extremely high requirements for aggregate particle shape, Process 2 should be chosen; if the main product is pure crushed stone with high raw material hardness, Process 1 is a more economical and reliable choice.
