Of course. Here is a detailed and professional configuration list for a marble grinding production line in Iran, presented in English suitable for technical inquiries and business communication.

### **Marble Powder Grinding Production Line Configuration for Iran (Capacity: 5-8 t/h, Fineness: 80-800 mesh)**

This configuration is designed for a medium-scale, versatile operation, producing marble powder for construction, putty, paint, and other industrial fillers.

---

#### **1. Core Design Premises**

*   **Raw Material:** Marble (Mohs hardness ~3), brittle, generally high whiteness.

*   **Product Fineness:** Adjustable between 80 to 800 mesh. This is the key factor determining equipment selection.

*   **Capacity:** 5-8 tons per hour.

*   **Mode:** A continuous, automated, and environmentally friendly production line.

#### **2. Recommended Equipment Configuration List**

| No. | Equipment Name | Recommended Model / Type | Key Function & Description |

| :--- | :--- | :--- | :--- |

| 1 | **Feeding Equipment** | Electromagnetic Vibrating Feeder (e.g., GZD series) | Provides uniform and continuous feeding of raw marble blocks from the hopper to the jaw crusher. Ensures stable operation. |

| 2 | **Primary Crushing Equipment** | Jaw Crusher (e.g., PE or PEX series) | Crushes large marble rocks (<500mm) into smaller pieces (≤50mm). This is a **mandatory** pre-processing stage for the grinder. |

| 3 | **Conveying & Elevating System** | Belt Conveyor & Bucket Elevator | Transports material horizontally and vertically between different stages, connecting the entire production line. |

| 4 | **Raw Material Silo & Feeder** | Steel Silo + Pendulum Feeder | Stores the crushed marble and provides a stable, controllable feed rate into the main grinder. |

| 5 | **Core Grinding Equipment (Host)** | **Suspension Roller Mill (Raymond Mill) or Vertical Roller Mill** | **The heart of the plant.** Modern Raymond Mills or Vertical Mills are highly efficient, energy-saving, and ideal for 80-800 mesh marble powder. **Example Models: 4R3216, 5R4125 Raymond Mill or equivalent Vertical Mill.** |

| 6 | **Classification System (Integrated)** | Turbo Classifier / Powder Separator | Integrated with the grinding host. Precisely controls the final product fineness by adjusting the rotor speed. Crucial for achieving the target mesh size. |

| 7 | **Finished Product Collection System** | **Pulse Jet Baghouse Dust Collector** (e.g., PPC / DMC series) | **Core environmental protection equipment.** Collects the final qualified powder with an efficiency >99.9%. Ensures emissions meet environmental standards and prevents dust pollution. |

| 8 | **Induced Draft Fan** | High-Pressure Centrifugal Fan (e.g., 9-19 / 9-26 series) | Provides the necessary airflow for the entire grinding system to transport the powder. The air volume and pressure are critical for output and fineness. |

| 9 | **Finished Product Silo & Packing System** | Finished Product Silos + Automatic Packing Machine (for valve bags/open bags) + Big Bag Packer | Stores the final marble powder and packs it automatically for sale and transport. |

| 10 | **Electrical Control System** | Central Control Cabinet (with PLC / Relay Logic) | Allows centralized start/stop and interlocked control of all equipment. Enables one-button operation, fault alarms, and improves safety and ease of use. |

| 11 | **Auxiliary Equipment (Optional but Recommended)** | **Magnetic Separator / Iron Remover** | Installed before the grinder or after packing. Removes tramp iron to protect the mill and, more importantly, to ensure high product purity and whiteness for premium applications. |

**Simple Process Flow:**

`Marble Ore` → `Vibrating Feeder` → `Jaw Crusher` → `Bucket Elevator` → `Raw Material Silo` → `Pendulum Feeder` → `Grinding Mill` → `Classifier` → `Dust Collector` → `Fan` → `Finished Product Silo` → `Packing Machine` → `Final Product`

#### **3. Key Considerations for Equipment Selection**

1.  **Choice of Grinding Mill:**

    *   **Raymond Mill / Vertical Mill:** The **optimal and most cost-effective** choice for the 80-800 mesh range. Vertical Mills generally offer higher energy efficiency and lower wear.

    *   Avoid Ball Mills for this application due to their high energy consumption and lower efficiency for marble.

2.  **Wear Parts Material:** The grinding rollers and ring/plate are key wear parts. Ensure the manufacturer uses **high-chromium alloy steel** or other advanced materials for long service life and low maintenance cost.

3.  **Environmental Compliance:** The **Pulse Jet Baghouse Dust Collector is mandatory**. It is not just for environmental regulations but also for product recovery and worker safety.

#### **4. Special Recommendations for Iranian Clients**

1.  **Supplier with Export Experience:** Prioritize Chinese manufacturers with extensive international project experience, **especially in Iran or the Middle East** (e.g., **Zenith Machinery, Liming Heavy Industry, SBM Group**). They can provide equipment compatible with local power standards and climatic conditions.

2.  **Installation & Commissioning Service:** Ensure the supplier includes engineer dispatch for installation guidance, commissioning, and operator training in the contract.

3.  **Spare Parts Supply:** Discuss the supply channel for wear parts. It is highly recommended to purchase a set of key spare parts (rollers, rings, bearings) with the initial order to minimize future downtime.

4.  **"Turnkey Project" (EPC):** For a hassle-free solution, consider an Engineering, Procurement, and Construction (EPC) contract where the supplier is responsible for the entire project from design to commissioning.

#### **5. Next Steps**

1.  **Define Your Specific Requirements:** Finalize your target capacity, primary product fineness, and budget.

2.  **Contact Top Suppliers:** Submit your requirements to 2-3 leading Chinese manufacturers.

3.  **Request a Grinding Test:** **Send your marble sample** to them for a free grinding test. This is the most critical step to get an accurate configuration proposal and quotation.

4.  **Compare Proposals:** Evaluate the test reports, detailed equipment lists, quotations, and after-sales service policies before making your final decision.
