30–50-tph-Soft-Rock-Crushing-Production-Line
I. Applicability: Small-to-Medium Scale Soft Rock Crushing
The GZD850×3000 + PF1007 + 2YZK1545 equipment configuration presented here is a highly efficient and cost-effective production line, custom-designed to meet soft rock crushing requirements with a throughput of 30–50 tons per hour (tph).
PF1007 Impact Crusher
Utilizing a closed-circuit process comprising "vibrating feeding—impact crushing—multi-layer screening," this solution achieves an optimal balance between equipment investment and operating costs while simultaneously ensuring superior quality in the shape of the finished product.
The following sections will provide detailed explanations regarding capacity matching, the rationale behind equipment selection, the specific process workflow, and the applicable operational boundaries.
II. Equipment Configuration and Technical Parameters
1. Core Equipment List
| Equipment Name | Model | Power | Main Function | Application Stage |
| Vibrating Feeder | GZD850×3000 | 7.5 kW | Uniform Feeding, Pre-screening | Front-end Feeding |
| Impact Crusher | PF1007 | 55 kW | Secondary Crushing & Shaping | Core Crushing |
| Circular Vibrating Screen | 2YZK1545 | - | Classification & Screening | Finished Product Screening |
2. Key Performance Parameters
• Processing Capacity: 30–50 tph (depending on feed size and finished product specifications)
• Feed Size: Recommended ≤150 mm (if raw material consists of large blocks, a primary jaw crusher is required upstream)
• Finished Product Specifications: Capable of producing 2–3 size fractions (e.g., 0–5 mm, 5–10 mm, 10–20 mm)
• Applicable Materials: Soft rocks with a compressive strength ≤350 MPa, such as limestone, coal gangue, etc.
III. Process Flow Description
1. Raw Material Supply:
Raw materials enter the GZD850×3000 vibrating feeder from the hopper; fine materials are pre-separated by a grizzly screen to reduce the ineffective load on the impact crusher.
2. Primary/Secondary Crushing:
Materials that have undergone pre-screening enter the PF1007 impact crusher, where crushing and shaping are achieved through high-speed impact by blow bars and repeated collisions.
3. Screening and Circulation:
The crushed material is conveyed to the 2YZK1545 double-deck circular vibrating screen for classification;
• Qualified finished products are discharged from their respective outlets;
• Oversized materials are returned to the impact crusher via a return conveyor belt for re-crushing, forming a closed-circuit loop.
IV. Equipment Manufacturing Standards
The manufacturing of the crusher and screening machine adheres to the relevant requirements regarding aggregate particle shape and gradation specified in the standard GB/T 14684-2022, *Sand for Construction*.
Capacity Calibration Basis:
PF1007 The impact crusher's capacity data is derived from typical limestone crushing test conditions (feed size ≤150 mm, discharge opening 20 mm).
Note: The parameters listed above are based on tests conducted on soft rock of medium hardness; actual capacity may vary depending on material hardness, clay content, and moisture content.

V. Frequently Asked Questions
Q1: Can this equipment directly crush large rocks up to 300 mm in size?
A: Not recommended. The PF1007 is better suited for small to medium-sized feed materials (≤150 mm). If the raw material consists primarily of 300 mm boulders, a small jaw crusher—such as the PE400×600—should be installed upstream to serve as a primary crusher.
Q2: Why choose the PF1007 over other models in the same class?
A: Within the 30–50 tph capacity range, the PF1007 offers superior cost-effectiveness and a more compact footprint, making it particularly well-suited for soft rock shaping and small-to-medium-scale sand and aggregate production lines.
Q3: What is the particle shape of the finished aggregate?
A: The aggregate produced by this impact crusher is predominantly cubical in shape, with a low content of needle-like and flaky particles. It meets the particle shape requirements for high-quality manufactured sand and crushed stone as stipulated in the GB/T 14684 standard.
Q4: How much space is required for this equipment configuration?
A: We recommend reserving an operating area of approximately 15 m × 10 m. The exact space requirements should be determined based on the specific placement of hoppers, the routing of conveyor belts, and the layout of the finished product stockpile area.
Q5: What is the energy consumption level?
A: The total installed power of the main crushing equipment is approximately 62.5 kW. During actual operation, electricity consumption can be further optimized through the use of variable-frequency feeding and load control systems.
