Mining Vibration Screen |
GN Mining Vibration Screen adopts domestic and foreign advanced technology and self-synchronized vibration principle for vibration motor excitation, rubber spring vibration damping, high wear-resistant material screen, sealed shaker basket, etc. It is of long life, low noise, and high screening efficiency, suitable for agglomerate, natural ore, coke and other powdery materials screening separation. According to different mineral separation needs, different opening screens can be selected. |

Decanter Centrifuge |
GN decanter centrifuge uses high-speed rotating centrifugal force, the G force can reach 3000G. It is widely used in solid-liquid separation of minerals, mineral concentration and dewatering. The decanter centrifuge in the mining industry usually adopts more advanced wear-resistant technology to extend the service life of the decanter centrifuge in mineral separation. Compared with the filter press, the decanter centrifuge is of smaller footprint, high degree automation, and simple operation. |

Horizontal Vibratory Centrifuge |
GN Horizontal Vibratory Centrifuge for Coarse Coal is used for dewatering of coarse coal in coal washing plants, and well-applied coal particle range is 0.5-5mm. The Horizontal Vibratory Centrifuge combines vibration and centrifugal force to realize high efficient dewatering performance of coarse coal particles. GN Horizontal Vibratory Centrifuge for Coarse Coal is a serialized product with the diameters of the screen basket varying from1000mm to 1600mm, which meets the processing capacity demand from 80t/h to 350t/h. After dewatering process by GN Horizontal Vibratory Centrifuge, the surface moisture on the coal is 5%-9%. |

Horizontal Screen Scroll Centrifuge |
GN Horizontal Screen Scroll Centrifuge for Fine Coal is used for fine coal dewatering in coal washing plant, and well-applied coal particle range is 0-3mm. The fine coal with water in this particle range is also called coarse slime. GN Horizontal Screen Scroll Centrifuge can remove the moisture in the fine coal or coarse slime by a high centrifugal force, and the coarse slime is discharged due to the differential speed between the scraper and the screen basket. GN Horizontal Screen Scroll Centrifuge adopts horizontal installation design to replace the traditional vertical scraper discharge centrifuge. The advantages are as following of that the replacement of wear parts can be realized in the horizontal direction, the height of the workshop is greatly reduced, the failure rate is lower, and the stability is better, which is the development trend of coarse slime dewatering equipment at home and abroad. GN Horizontal Screen Scroll Centrifuge for Fine Coal is a serialized product; the screen basket diameter is from 900mm to 1200mm, which meets the processing capacity demand from 30 tons/h to 120 tons/h. After dewatering by GN Horizontal Screen Scroll Centrifuge, the surface moisture of coarse slime is about 12-16%. |

Screen Bowl Decanter Centrifuge |
GN Coal Dewatering Screen Bowl Decanter Centrifuge is used for dewatering of ultrafine coal in coal washing plant, and well-applied coal particle range is usually 0-0.5mm. The Coal Dewatering Screen Bowl Decanter Centrifuge is with screw propeller inside the bowl. Its straight bowl section is closed type and similar to Decanter Centrifuge, and the cone bowl section has mesh holes on it. GN Coal Dewatering Screen Bowl Decanter Centrifuge adopts the principle of "centrifugal sedimentation" and "centrifugal filtration" to carry out solid-liquid separation. Ultrafine coal slurry enters the centrifuge through the feed pipe, and goes through two stages of centrifugal sedimentation and centrifugal filtration, with the help of centrifugal force, finally comes out three products, Dewatered Coal, Filtered Water and Centrifugal Water. The filtered water can be re-entered into the centrifuge as circulating material. GN Coal Dewatering Screen Bowl Decanter Centrifuge is a serialized product; there are 5 models with bowl diameter from 900mm to 1600mm, and processing capacity from 10 tons/h to 100 tons/h. The surface moisture of ultrafine coal is about 14~24% after dewatering by GN Coal Dewatering Screen Bowl Decanter Centrifuge. |

Slant Plate Clarifier |
Slant Plate Clarifier is widely used in the sedimentation treatment of minerals. The principle is to use gravity to make solid particles to fall on the surface of the slant plate and fall down to the sludge collection trough. The clarified wastewater flows out via outlet at the top of the slant plate clarifier. The slant plate clarifier is of large handling capacity and low cost; but the discharged solid is high moisture, which requires further dewatering treatment. |

Conveying Equipment |
GN conveying equipment applied in the mining industry includes: screw conveyor, scraper conveyor, bucket elevator; etc. GN conveying equipment is widely used in the transportation of bulk materials in the mining industry: including coal mines, porcelain clay, calcium carbonate, titanium dioxide, barite, zinc sulfate, aluminum hydroxide, metal minerals, etc. |
 |
Solids Vacuum Pump |
GN solids vacuum pump is a pneumatic pump with strong self-priming ability, vacuum degree up to 25 inches of mercury, and discharge head up to 80 meters. It can transport solids, liquids, and solid-liquid mixtures. GN solids vacuum pumps are widely used in the mining industry for mineral suction, mud transportation, and long-distance transportation of bulk materials. Unlike other rotary conveying pumps, GN solids vacuum pump has no rotating parts; therefore, it has better wear resistance in mineral transportation. |

Centrifugal mud pump |
GN Centrifugal Mud Pump is unlike ordinary centrifugal water pumps, it can transport mud with a solid content up to 20%. In mineral mud treatment, it is often used as feeding pump or mud-transportation pump . |
