What Does Henry Say?

In 2021, JXSC successfully delivered a customized hard usine de broyage de calcaire for our valued client, achieving smooth shipment and on-site installation by 2022. The plant has consistently maintained stable production between 250–300 TPH with excellent final product quality. Notably, thanks to our reliable and maintenance-friendly equipment design, operational costs remain 20% lower than industry standards. The client highly appreciated our seamless coordination and punctual delivery, which allowed them to commence production two weeks ahead of schedule. This project’s success stemmed from our tailored equipment selection, proactive modular planning, and full lifecycle support—from engineering to commissioning and training—ensuring efficient and long-term operations.

How We Delivered a 300TPH Limestone Plant to Cambodia Against Tight Timelines?

Introduction

In the competitive world of équipement de concassage de pierres supply, meeting stringent demands for quality, durability, and delivery speed is what distinguishes leading suppliers from others. This case study explores how we successfully partnered with a Cambodian client to establish a 250-300TPH hard limestone crushing plant, overcoming challenges and exceeding expectations.

Aperçu du projet

Localisation : Cambodia
Capacité de traitement : 250–300 tons per hour
Matière première : Hard Limestone
Max Feeding Size: 500–600mm
Final Products: 0–8mm, 8–21mm, 21–30mm
Key Requirements: High-quality machinery, low maintenance, fast delivery

Limestone Crushing Production Line Process Flow

1. Primary Crushing Stage
Raw limestone is initially fed into a coarse jaw crusher for primary size reduction.

2. Secondary Crushing Stage
The crushed material from the jaw crusher is then transported to a cone crusher for further reduction.

3. First Screening & Recirculation
La sortie du concasseur à cône is screened via a primary vibrating screen, which classifies the material into:

21-30mm: Accepted as final product
<21mm: Sent to a fine jaw crusher for additional processing
>30mm: Returned to the cone crusher for re-crushing

4. Tertiary Crushing & Final Screening

The material processed by the fine jaw crusher is conveyed to a secondary écran vibrant, where it is separated into:

0-8mm: Fine-grade final product
8-21mm: Medium-grade final product

Key Features:

Closed-circuit crushing ensures optimal efficiency and consistent product sizing.
Multi-stage screening maximizes material utilization and minimizes oversize waste.
Robust design minimizes operational downtime and maintenance costs.

Equipment Purchased by The Customer

The detailed specifications of the main equipment are as follows:
1. Jaw crusher : 1 set PE900x1200 , capacity : 220-450tph , 132kw
2. Cone crusher: two sets DN1750, capacity 285-460t/h, 220kw
3. Vibrating screen: 1 set 2YD2465, 30kw, mesh: 30mm,21mm; 1 set 3YD2470, 30kw, mesh: 8mm, 21mm, 30mm.
4. Jaw crusher: two set PE600x900, cpacity:60-180tph , 75kw, these two used in other line.

Q&A: Addressing the Client’s Core Concerns

Q1: The client emphasized the need for “high-quality machinery.” How did you ensure equipment reliability for processing hard limestone?
A : Hard limestone is abrasive and demands robust crushing solutions. We recommended a configuration comprising a heavy-duty jaw crusher for primary crushing, two cone crushers for secondary crushing, and high-wear-resistant screens. All equipment was manufactured with premium-grade steel and underwent strict factory testing to ensure durability, stable output, and long service life under high-load conditions.

Q2: Low maintenance was a critical requirement. How did your plant design minimize downtime?
A : We integrated several smart features: centralized lubrication systems, easily accessible inspection points, and modular wear parts. The cone crusher was equipped with an automatic hydraulic adjustment and clearing system, reducing manual intervention. Additionally, we provided comprehensive training and detailed maintenance manuals, empowering the client’s team to perform routine checks efficiently.

Q3: The project timeline was tight. How did you manage to deliver and install the plant so quickly?
A : Fast delivery was a make-or-break factor. Leveraging our standardized modular design and in-stock component inventory, we assembled, tested, and dispatched the major equipment within 30 days. Close coordination with logistics partners ensured smooth shipping to Cambodia. Our installation team arrived promptly, and with pre-prepared foundations, the plant was commissioned in just four weeks.

Q4: How did you ensure the final product gradations (0-8mm, 8-21mm, 21-30mm) were accurately achieved?
A : We designed a three-stage crushing and screening circuit, optimized through simulation software. Adjustable crusher settings and precisely sized vibrating screens allowed fine-tuning of product sizes. On-site calibration during commissioning guaranteed that each fraction met the exact specifications with high consistency.

Results & Feedback

The plant achieved a steady output of 250–300TPH with excellent product shape.
Maintenance costs remained 20% below the industry average due to the equipment’s reliability and accessible design.
The client commended the seamless coordination and on-time delivery, which allowed their project to commence operations two weeks ahead of schedule.
