Understanding Low Intensity Magnetic Separators
A low intensity magnetic separator (LIMS) is designed to remove ferromagnetic contaminants from coarse materials, slurries, mineral feeds, and industrial powders. Operating typically under 2,000 gauss, LIMS solutions are essential in improving product purity, preventing equipment wear, enhancing downstream processing efficiency, and ensuring consistent output quality.
Industries using LIMS technology include:
- Mining & mineral processing
- Feldspar, quartz & kaolin refinement
- Ceramics & porcelain production
- Food & chemical processing
- Powder metallurgy
- Recycling & metal recovery
Because each industry and application demands different magnetic field strengths, material-handling configurations, and separation accuracy, selecting the right LIMS requires careful evaluation. This guide highlights the best-performing models on the market in 2025.

1. ZT Plate Type Permanent Magnetic Separation Equipment
Brand Name: ZT
Model: ZT-1530P
Certification: ISO9001
Origin: Foshan, Guangdong, China
Overview
The ZT Plate Type Permanent Magnetic Separation Equipment is one of the most advanced and reliable solutions in the low intensity magnetic separator category. It is ideal for removing ferrous impurities from dry or semi-dry materials, making it a preferred option for ceramics, minerals, quartz, feldspar, and chemical industries.
Key Customization Option
High Gradient Plate Magnetic Separator — tailored for industries requiring stronger magnetic performance and finer separation precision.
Key Specifications
- Minimum Order Quantity: 1 set
- Price: Negotiable
- Packaging: Standard exporting package
- Delivery Time: Within 25 days after downpayment
- Payment Terms: L/C, T/T
- Supply Ability: 50 sets per month
Why It Stands Out
- High-performance permanent magnet technology
- Reliable, maintenance-friendly structure
- Strong separation capability for various dry materials
- High durability for industrial environments
This model remains one of the most sought-after low intensity magnetic separators due to its precision, affordability, and customization flexibility.
2. Water-Cooling Electro-Magnetic Separator (For Kaolin, Feldspar, Quartz)
This powerful water-cooled electromagnetic separator is engineered for ultra-high purity applications and industrial environments requiring continuous heavy-duty performance. While not strictly a low-intensity separator (due to its high gauss rating), it often performs similar roles in slurry-based mineral refining lines.

Frequently Asked Questions
1. What industries use a low intensity magnetic separator?
Industries include mining, ceramics, chemical processing, quartz refinement, feldspar production, powder metallurgy, and recycling.
2. What is the difference between low and high intensity magnetic separators?
Low intensity separators use magnetic fields under 2,000 gauss for ferromagnetic materials, while high intensity units (10,000+ gauss) target paramagnetic materials such as kaolin, quartz, and feldspar.
3. How do I choose the right LIMS?
Consider material type (wet or dry), particle size, required purity level, magnetic strength, and processing capacity.
4. How often do magnetic separators require maintenance?
Maintenance intervals vary by model, but most require periodic cleaning and inspection to ensure optimal separation efficiency.
5. What is the lifespan of a LIMS system?
High-quality systems can last 8–15 years depending on usage and operating environment.
