Magnetic Metal Separation Of Building Material Aggregates

Hengji Magnetic & Electrical serves as an essential quality guardian in the building materials and aggregates industry, providing critical protection and value enhancement through advanced magnetic metal separation technology. Our equipment delivers fundamental benefits across the entire production chain, from protecting expensive machinery to elevating final product quality. The strategic implementation of magnetic metal separation processes ensures that raw building materials meet stringent quality standards while maximizing operational efficiency and minimizing downtime in building materials aggregates production.

 

The role of our technology extends across multiple applications within the building materials aggregates sector. For premium applications such as high-purity quartz processing, our systems enable significant value addition through precise magnetic metal separation. Meanwhile, in standard building materials aggregates production lines, our equipment provides indispensable protection against damaging metal contaminants. This comprehensive approach to magnetic metal separation makes our solutions vital for both quality enhancement and equipment protection in processing raw building materials.

 

 

I. Premium Application: Deep Iron Removal from Quartz and Silica Sand

 

The purification of quartz sand represents one of the most valuable applications of magnetic metal separation in the building materials industry. High-purity quartz sand serves as a critical raw building materials component for manufacturing premium glass products, including ultra-clear glass, photovoltaic glass, and optical glass.

 

Application Context and Importance:

Natural quartz sand typically contains weakly magnetic impurity minerals that significantly impact final product quality. These impurities can affect transparency in glass products and cause discoloration in ceramic applications. Implementing advanced magnetic metal separation processes reduces iron content from initial levels of several hundred ppm down to single-digit ppm levels, dramatically increasing the value of these raw building materials.

 

Application Context and Importance

 

Core Equipment and Technology:

 

The GTC Series Plate-Type High-Gradient Magnetic Separator delivers exceptional performance for this demanding application:

  • Achieves magnetic intensity up to 18,000 Gauss for capturing fine weakly magnetic particles

  • Innovative plate-type design prevents clogging issues common with conventional separators

  • Provides world-class magnetic metal separation performance at significantly lower cost

  • Ensures continuous operation in processing high-value raw building materials

 

 

II. Fundamental Application: Metal Protection in Aggregates Production

 

In large-scale building materials aggregates production facilities, metal contaminants pose constant threats to equipment integrity and product quality. Our magnetic metal separation solutions provide comprehensive protection throughout the production process.

 

Application Context and Importance:

Metal contaminants entering crushing and processing equipment cause severe damage to critical components, resulting in expensive repairs and production stoppages. Additionally, metal contamination in final building materials aggregates products compromises quality standards for concrete and other construction applications.

 

Core Equipment and Solutions:

  • RCT Series Permanent Magnet Drums: Install directly as conveyor drive pulleys to capture buried tramp metal throughout the material bed, providing superior protection for downstream crushers and processors in building materials aggregates production lines

  • Suspended Plate Magnets: Position above conveyors to remove surface metal contaminants, working in conjunction with permanent magnet drums for comprehensive magnetic metal separation protection

III. Expanded Applications: Non-Metallic Mineral Purification and Waste Recovery

 

Beyond primary applications, magnetic metal separation technology delivers significant value across various other raw building materials processing operations.

 

Feldspar, Kaolin, and Potash-Soda Feldspar Purification:

Similar to quartz processing, these ceramic and glass raw building materials require iron removal to enhance whiteness and product quality. Both CTB Series wet magnetic separators and high-intensity magnetic roll separators provide effective magnetic metal separation solutions for these applications.
