Dolomite milling line for Egypt magnesium production

Introduction: Egypt’s Dolomite Resource and Magnesium Production Potential

Egypt possesses abundant dolomite reserves, particularly in the Eastern Desert and Sinai Peninsula. Dolomite (CaMg(CO3)2) is a key raw material for magnesium production, as it can be processed into magnesium oxide (MgO) and then reduced to metallic magnesium through the Pidgeon process or other thermal reduction methods. Establishing an efficient dolomite milling line is crucial for achieving high-purity magnesium products. Shanghai Zenith Machinery Co., Ltd., an excellent manufacturer of ore grinding equipment in China, has made great achievements in the field of ultra-fine powder grinding. Our advanced milling solutions are tailored to meet the specific requirements of Egypt’s magnesium industry, ensuring high capacity, low energy consumption, and precise particle size control.

Dolomite Beneficiation and Grinding Requirements

For magnesium production, dolomite must be ground to a fine powder with controlled particle size distribution. The typical target fineness ranges from 100 to 325 mesh (0.15–0.045 mm) for direct calcination, or even finer (up to 600 mesh) for ultra-fine applications. The grinding process must also handle the hardness of dolomite (Mohs 3.5–4) and its abrasive nature. Key parameters for the milling line include feed size (usually <50 mm), moisture content (below 6%), and capacity requirements (from 10 t/h to 45 t/h depending on plant scale).

Recommended Milling Equipment for the Line

Based on our extensive experience and product portfolio, we recommend two core machines for an Egyptian dolomite milling line: the MTW Trapezium Grinding Mill and the LUM Ultrafine Vertical Mill. These units are engineered to deliver superior performance, durability, and environmental compliance.

MTW Trapezium Grinding Mill – Ideal for Medium-to-Fine Dolomite Grinding

The MTW series trapezium mill is a multi-patent grinding mill renowned for its compact structure, long service life, and eco-friendly design. It is suitable for processing dolomite with maximum input size up to 50 mm, producing final products as fine as 0.038 mm (400 mesh). The following parameters make it an excellent choice for Egyptian magnesium projects:

Model	Max. Feed Size (mm)	Final Size (mm)	Capacity (t/h)	Main Motor (kW)
MTW110	<30	1.6–0.045	3–9	55
MTW138Z	<35	1.6–0.045	6–17	90
MTW175G	<40	1.6–0.045	9.5–25	160
MTW215G	<50	1.6–0.045	15–45	280

For a typical Egyptian dolomite grinding line with a capacity of 20–30 t/h, the MTW175G is highly recommended. Its heavy-duty main motor and advanced classifier ensure consistent product fineness and low operating costs.

LUM Ultrafine Vertical Mill – For High-Purity Ultra-Fine Magnesium Oxide

When magnesium production requires ultra-fine dolomite powder (325–600 mesh) for advanced applications, the LUM Ultrafine Vertical Mill is the optimal solution. This mill integrates grinding, drying, classifying, and transportation into one unit, occupying minimal space. It features intelligent control and produces powders with high content of end-fines. Key models for Egyptian projects include:

Model	Main Machine Power (kW)	Capacity (t/h)	Size Distribution D97 (μm)
LUM1525	220–250	1.6–11.5	5–30
LUM1632	280–315	2.0–13.5	5–30
LUM1836	355–400	2.3–15	5–30

The LUM1632 is ideal for mid-scale production, delivering up to 13.5 t/h of product with D97 down to 5 μm. Its low energy consumption per ton and reduced wear rates make it a cost-effective choice for Egyptian magnesium manufacturers aiming for high-value products.

Complete Milling Line Configuration

A typical dolomite milling line for Egypt magnesium production consists of the following stages: dumping hopper → vibrating feeder → jaw crusher (primary reduction) → bucket elevator → raw material silo → electromagnetic vibrating feeder → main grinding mill (MTW or LUM) → classifier → baghouse dust collector → finished product silo. The entire system is controlled by a centralized PLC for automated operation. Our team provides comprehensive engineering support, from site survey to commissioning.
