JH-LX is a self-cleaning permanent magnetic separator for gravity-fed dry powders, including high-purity silica. It can remove iron contaminants approximately 80 μm in diameter, with automatic pneumatic cleaning and configurable magnetic rods. Selection depends on your material, throughput and installation conditions.
What Size of Iron Contaminants Can JH-LX Remove?
JINHONG specifies the JH-LX system for removing iron contaminants approximately 80 μm in diameter. This describes the iron contamination, not the particle size of the powder being processed. It is not a guarantee that every particle of that size will be removed.
For silica powder, provide both the feed particle-size distribution and the iron contamination to be removed. Material flow, moisture, feed rate and the selected magnetic arrangement must be considered when assessing the application.
How Does Its Iron-Removal Rate Compare with Conventional Magnetic Rods?
JINHONG reports that the JH-LX complete system can achieve 1.3 times the iron-removal rate of a conventional magnetic-rod setup under the same operating conditions. This means an approximately 30% relative improvement, not an additional 30 percentage points.
This comparison applies to the complete JH-LX system, not to every individual magnetic rod. Use the same material, feed conditions and measurement method when comparing configurations. Confirm the reference configuration and performance criteria during application review; the ratio is not a fixed removal-rate guarantee for every material.
How Does Automatic Cleaning Fit into a Powder Line?
JH-LX uses pneumatic cleaning with PLC control and touchscreen operation. The reference air supply is at least 0.5 MPa. External dust collection carries away discharged iron and dust; the complete installation determines dust-control performance.
- Installation can be reviewed for round or square gravity-flow pipelines.
- Potential locations include downstream of screens or feeding stations and upstream of packaging equipment.
- JH-B cylindrical cores and JH-L helical-field cores are available for application review.
- Magnetic rod dimensions and magnetic field strength can be customized. The quotation should identify the selected size, measurement surface and operating temperature.
JH-LX, Drawer Separator or Magnetic Grate: Which Arrangement Fits?
The table compares three product arrangements in the JINHONG range. It is a selection guide, not a comparative performance test or a ranking of competing manufacturers.
| Selection point | JH-LX automatic separator | JH-X08 drawer separator | Magnetic grate |
|---|---|---|---|
| Cleaning arrangement | Pneumatic automatic cleaning with PLC control | Drawer access for cleaning; confirm the supplied arrangement | Manual or easy-clean structure, depending on configuration |
| Installation focus | Gravity-fed powder lines requiring automatic cleaning | Powder lines with access for drawer withdrawal | Hoppers or gravity-flow passages with access for grate cleaning |
| Published reference | Compressed air ≥0.5 MPa; external dust collection required | 28, 42 or 84 rods in the published model reference | 25 mm rods at 50 mm centres in the published standard arrangement |
| Details to confirm | Feed conditions, cleaning cycle, air supply, extraction and height | Model, feed characteristics, installation and withdrawal space | Shape, dimensions, rod arrangement and cleaning access |
| Product details | See JH-LX model references below | JH-X08 drawer separator | Magnetic grate configurations |
Reference dimensions and rod arrangements describe particular configurations. They do not establish equivalent throughput or removal performance across these products. For liquids, use a liquid-line magnetic trap rather than this dry-powder selection guide.
Which JH-LX Models and Dimensions Are Available?
06C-12000 is a model within the JH-LX series. Read the 06C-12000 silica micropowder application. The dimensions below are separate model references; do not apply them to 06C-12000 without confirming its drawing.
| Model | Units | Total layers / assemblies | Cylinder pairs | Reference dimensions (mm) |
|---|---|---|---|---|
| JH-04B | 2 | 8 / 32 | 4 | 1766 × 360 × 768 |
| JH-06B | 3 | 12 / 48 | 6 | 1766 × 360 × 1008 |
| JH-12B | 6 | 24 / 96 | 12 | 1766 × 360 × 1722 |
| JH-06X — fine-powder configuration | 3 | 6 / 27 | 6 | 1842 × 360 × 1008 |
Final dimensions and configuration follow the agreed drawing, inspection report and order contract. Non-standard designs can be reviewed for your installation.
What Air, Temperature and Dust-Collection Conditions Are Required?
| Item | Reference requirement / selection note |
|---|---|
| Compressed air pressure | At least 0.5 MPa |
| Air quality | Dew point −20°C; oil-free, purified air for electronic-material applications |
| Dust collection | Pressure greater than 2,000 Pa and airflow greater than 400 m³/h; confirm the complete extraction arrangement |
| Standard operating temperature | ≤80°C; higher-temperature configurations require separate confirmation |
| Magnetic field specification | Confirm rod dimensions, core type, bare-rod or sleeve measurement surface, measurement position and inspection requirements |
What Production Experience Supports Silica Powder Applications?
JINHONG has supplied an electronic-grade silica powder manufacturer with 200 magnetic separation units over time. The earliest units have been used for seven years, and the customer has purchased additional equipment each year. These figures describe the supply relationship; they do not mean that all 200 units are JH-LX models or that all units have operated for seven years.

Frequently Asked Questions About JH-LX Powder Separation
Can JH-LX remove 80 μm iron particles from high-purity silica powder?
JH-LX can remove iron contaminants approximately 80 μm in diameter. That figure refers to the iron particles, not the silica feed size. Actual removal depends on material properties, contamination, feed conditions and configuration. Send representative material information for application review.
Does a 1.3-times removal rate mean a 130% improvement?
No. A rate that is 1.3 times the comparison rate represents a 30% relative improvement. It does not mean a 130% improvement or an increase of 30 percentage points. The JH-LX comparison requires the same operating conditions.
Is 06C-12000 a separate product from the JH-LX series?
No. 06C-12000 is one model within the JH-LX series. Its installation dimensions and operating specifications should be confirmed for the selected configuration rather than copied from another JH-LX model.
Can magnetic rod size and magnetic field strength be customized?
Yes. Rod dimensions and field strength can be configured for the application. Specify the installation space, material, working temperature and inspection requirements. Field values must identify the measurement position and whether they apply to a bare rod or an external sleeve.
Does a self-cleaning magnetic separator still require maintenance?
Yes. Automatic cleaning does not replace inspection and maintenance. The operating plan should cover cleaning cycles, compressed-air quality, dust collection and the supplied moving components.
What information is needed to quote a magnetic separator for silica micropowder?
Send material name, feed particle-size distribution, bulk density, moisture, throughput, temperature, pipeline dimensions and available height. Include iron contamination type and size, current and target iron levels, and the measurement method where available. A process sketch helps define the installation.
