High-Capacity Secondary Crushing Machine Cone Crusher PYB2200

Finding the right cone crusher for a large-scale operation can be challenging. You need equipment that delivers consistent output, handles hard materials efficiently, and remains cost-effective over years of operation. For many large mining and aggregate projects, the PYB2200 spring cone crusher represents the pinnacle of capacity in the PYB series—a true workhorse designed for high-tonnage secondary crushing. This guide covers everything you need to know about the PYB2200 spring cone crusher, including technical specifications, working principles, structural features, applications, and real-world performance. 

What Is PYB Series Spring Cone Crusher?

The PYB series spring cone crusher is a compression-type crusher designed for secondary crushing in mining, aggregate, and construction applications. It is one of the most widely used cone crusher types globally, known for its simple structure, reliable operation, and cost-effective maintenance.

The "PYB" designation indicates the standard type, which is specifically designed for medium crushing (secondary crushing). The series also includes:

  ● PYZ – medium type for intermediate crushing

  ● PYD – short-head type for fine crushing

What Makes Spring Cone Crusher Unique?

The defining feature of a spring cone crusher is its spring safety system—it serves as an overload protection device. When uncrushable objects (like tramp iron) enter the crushing chamber, the spring system allows the discharge opening to expand, letting the object pass through without damaging the machine.

Key advantages include:

  ● High productivity – continuous rotation of the crushing cone enables efficient operation

  ● Low power consumption – optimized design reduces energy costs

  ● Even product size – produces uniform, cubical-shaped aggregates

  ● Reliable operation – glycerin or water sealing systems isolate dust from lubrication oil

PYB2200: Technical Specifications

The PYB2200 is the flagship model in the cone crusher PYB series, delivering the highest capacity among spring cone crushers. Based on multiple manufacturer data sources, here are the key specifications:

Note: Capacity varies based on material hardness, feed size distribution, and moisture content.

Key Components & Structural Design

The spring cone crusher consists of several key components working together to achieve efficient crushing:

  ● Frame – the main support structure holding all components

  ● Transmission Device – motor, gears, and driveshaft that transfer power

  ● Hollow Eccentric Shaft – drives the oscillating motion of the crushing cone

  ● Bowl-Shaped Bearing – supports the crushing cone assembly

  ● Crushing Cone (Mantle) – the moving crushing surface

  ● Spring Mechanism – provides overload protection

  ● Hydraulic/Pneumatic Station – used for adjusting discharge opening

The heavy-duty construction of these components ensures reliable performance even under continuous high-load operation.

Working Principle of PYB Series Cone Crusher

Understanding how the spring cone crusher works helps in proper operation and maintenance:

The crushing process follows this sequence:

1. Motor drives the eccentric shaft – through a horizontal axle and bevel gear pair, the motor rotates the eccentric sleeve

2. Crushing cone swings – the axis of the crushing cone moves with the eccentric shaft force, bringing the mantle close to and away from the concave surface

3. Material is compressed and crushed – when the mantle approaches the bowl liner, rocks and ores are squeezed, pressed, and crushed

4. Discharge occurs – when the mantle moves away, crushed material falls through the opening by gravity

5. Spring protection activates – if uncrushable material enters, the spring allows the crushing cone to retreat, protecting the machine

6. The continuous rotation of the operated cone body and the high productivity of this design make it particularly effective for large-scale operations.

Main Applications for PYB2200 Cone Crusher

Ideal Materials: PYB series cone crushers are suitable for crushing a wide range of mid-hard to hard ores and rocks:

  ● Iron ore – common in large mining operations

  ● Copper ore – secondary crushing in mineral processing

  ● Limestone – widely used in cement and aggregate production

  ● Granite – hard rock suitable for high-quality aggregates

  ● Basalt – ideal for road construction materials

  ● Quartz – high hardness material

  ● Cobblestone / pebbles – river stone processing

  ● Sandstone – construction material

Key limitation: The material's compressive strength should generally be within the machine's design parameters (typically under 300 MPa for optimal performance).

Baichy Machinery 300 TPH Two-Stage Crushing Plant Case Study in Malaysia

In early 2025, Baichy Machinery supplied a 300 TPH two-stage crushing plant to a Malaysian aggregate producer in Johor. The plant processes hard granite for road base and concrete production. The primary stage uses a PE750X1060 jaw crusher, reducing 600mm feed to 150-200mm. Material then flows to a ground-level surge bin, which acts as a buffer to ensure continuous, even feed to the secondary stage. From the surge bin, a belt conveyor delivers material to the PYB2200 spring cone crusher, which efficiently produces 30-60mm output at 300 TPH. A vibrating screen separates finished products, with belt conveyors connecting all stages.

The PYB2200's robust spring protection ensures reliable operation. The plant has consistently delivered 300 tons per hour with excellent product shape and minimal downtime, significantly reducing operating costs. Since commissioning, the plant has consistently delivered 300 tons of quality aggregates per hour with excellent cubical shape. The client reported minimal downtime and significantly reduced operating costs compared to their previous setup. The reliable performance of the PYB2200 cone crusher and the smooth integration of all components have made this Baichy solution a benchmark for cost-effective aggregate production in the region.

The PYB2200 spring cone crusher represents a proven, reliable solution for high-capacity secondary crushing applications. Its combination of simple structure, robust design, and cost-effective operation makes it a popular choice for large-scale mining and aggregate operations worldwide.
