200 T/H Limestone Crushing Production Line Configuration Scheme
In the field of mining crushing, production line capacity and finished product particle size are core indicators for measuring project efficiency. For a limestone crushing project with an hourly output of 200 tons, simultaneously requiring the production of two commonly used building aggregate sizes—10-20 mm and 16-31.5 mm—how to configure an efficient, stable, and economical production line has become a focus for many investors.
As a marketing expert with many years of experience in the mining equipment field, I will provide an in-depth analysis of the core points of this production line, combining actual market needs with technological development trends.
I. Production Line Design Concept and Core Challenges
Limestone, as a medium-hardness material, has a relatively mature crushing process. However, to simultaneously meet two strict particle size ranges and ensure production capacity, the key lies in "multi-stage crushing, fine screening, and flexible control." The production line needs to have good particle size adjustment capabilities to avoid over-crushing, while ensuring system smoothness and controllable energy consumption.
Common challenges include:
1) a wide particle size range after primary crushing;
2) effective separation of the two target sizes after secondary crushing; and
3) system capacity balance and equipment load optimization.

II. Core Equipment Configuration Scheme
A high-efficiency 200-ton/hour limestone production line typically adopts a three-stage crushing process (coarse crushing, medium crushing, and fine crushing) combined with multi-stage screening. The following is a recommended basic configuration:
| Process | Equipment Type | Recommended Model | Key Function | Estimated Output Particle Size |
| Coarse Crushing | Jaw Crusher | PE-750×1060 | Primary crushing of large limestone pieces, high processing capacity, stable and reliable | ≤200mm |
| Medium Crushing | Impact Crusher/Cone Crusher | PF-1315/HPT300 | Medium to fine crushing, shaping particles for easy particle size control | ≤60mm |
| Fine Crushing and Shaping | mpact Crusher/High-Efficiency Fine Crusher | VSI1140/XPCL | Further crushing and optimizing particle shape to improve finished product quality | ≤31.5mm |
| Screening | Multi-Layer Circular Vibrating Screen | 3YK3070/4YK3080 | Grading and screening to separate 10-20mm, 16-31.5mm, and oversized materials. | Multiple Output Specifications |
Note: Specific models need to be fine-tuned based on material hardness, soil content, moisture content, and other characteristics. Impact crushers are more suitable for scenarios with medium hardness and high requirements for product particle shape; cone crushers have advantages in wear resistance and long-term operational stability.

III. Key Points for Particle Size Control and Process
Optimization To achieve precise output of both 10-20mm and 16-31.5mm specifications, the design of the screening system is crucial. It is recommended to use a three- or four-layer vibrating screen, with the upper screen mesh size approximately 31.5mm, the middle screen mesh size approximately 20mm, and the lower screen mesh size approximately 10mm. Oversize material (>31.5mm) can be returned to the medium or fine crushing equipment for further crushing, forming a closed-loop cycle to ensure that the output rate and particle size meet the standards.
Simultaneously, by adjusting the crusher discharge port and optimizing the screen inclination angle and vibration frequency, the output ratio of the two finished products can be flexibly adjusted to cope with market changes. It is recommended to equip the system with an intelligent control system to monitor equipment load and output particle size in real time, achieving automated adjustment, reducing manual intervention, and improving overall stability.
IV. Market Competitiveness and Investment Value
This production line not only meets the demand for high-quality aggregates from concrete mixing plants, asphalt mixing plants, and road construction, but its flexible dual-specification output capacity also enhances customers' market adaptability. From a marketing perspective, highlighting core selling points such as "high efficiency and energy saving, multi-product capability, and intelligent control" can significantly improve the project's attractiveness. Furthermore, providing customized design solutions, installation and commissioning support, and long-term maintenance services will be key to winning customer trust.
A limestone crushing production line with a capacity of 200 tons per hour, under reasonable process design, reliable equipment selection, and precise operational control, can stably produce a high proportion of qualified dual-specification aggregates. As an equipment manufacturer, we should not only provide high-performance crushing and screening equipment, but also become a partner in customers' production solutions, helping them achieve long-term profitability and sustainable development.
