30-40tph Hard Stone Crushing Plant With Spring Cone Crusher In Peru Share

This represents a typical small-to-medium-scale hard rock crushing production line. Its core design principle lies in leveraging the exceptional secondary and tertiary crushing capabilities of a spring cone crusher to process highly abrasive hard rocks—such as granite, basalt, and quartzite—thereby producing aggregates with superior particle shape.

1. Core Equipment Selection – Spring Cone Crusher

The spring cone crusher features a robust structure and utilizes springs to provide effective tramp iron protection; consequently, it offers higher reliability than hydraulic cone crushers when operating conditions are unstable or when uncrushable objects inadvertently enter the feed stream. For mining projects in Peru, equipment stability and ease of maintenance are paramount considerations.

• Recommended Model: PYB 900

• Rationale:

• Capacity Match: The PYB 900 (Short Head type, designed for fine crushing) offers a processing capacity of approximately 15–50 tons per hour when the Closed Side Setting (CSS) is set between 10 mm and 25 mm—a range that fully meets your specific production volume requirements. If the feed material consists of larger particle sizes, a PYB 1750 (Standard type, designed for secondary crushing) can be installed upstream to serve as a primary crusher.

• Superior Product Shape: Material produced by cone crushers typically exhibits a predominantly cubical shape with low levels of flaky and needle-like particles, making it the ideal choice for producing high-quality concrete aggregates.

• High Wear Resistance: When processing hard rock, it is imperative to select manganese steel liners or higher-grade alloy steel liners to ensure durability and longevity.

2. Recommended Process Flow for a Complete Crushing Station

For hard rock crushing projects in Peru, achieving a stable and reliable output of 30–40 tons per hour is best accomplished through an optimal configuration consisting of a stationary production line: "Vibrating Feeder + Jaw Crusher (Primary Crushing) + Spring Cone Crusher (Secondary & Tertiary Crushing) + Vibrating Screen (Closed-Circuit Operation)."

Spring cone crushers are not suitable for directly processing large blocks of raw ore (typically exceeding 200 mm). It is mandatory to first employ a jaw crusher for primary crushing to reduce large ore blocks to a size of 100–150 mm or smaller before feeding them into the cone crusher for secondary and tertiary reduction. This constitutes the most classic and cost-effective "Jaw Crusher + Cone Crusher" two-stage crushing solution.
