Dust collector in beneficiation plant

The dust collector in the beneficiation plant uses an automatic induced draft fan to suck the scattered dust from the mining machinery into the bag type dust removal equipment for treatment. It has the characteristics of simple operation, convenient operation, and low maintenance workload. It can be applied to the dust collection and recovery of various dust producing points on the production lines of crushing plants such as jaw crushers, impact crushers, cone crushers, and vibrating screens. According to the characteristics of dust source, wet dust prevention measures such as spraying dust suppression, spray dust suppression, and covering dust prevention are adopted for the dust remover of the concentrator. When wet dust prevention is unconditionally used in frozen and water scarce areas or cannot meet the required standards after wet dust prevention, a comprehensive method of mechanical dust removal or a combination of mechanical dust removal and wet dust prevention should be used.

Characteristics of Dust Collector in Mineral Processing Plant:

1. The processing of flower board bag holes adopts CNC laser cutting, which has good accuracy, fast progress, and smooth edges without burrs.

2. The production of dust removal skeleton adopts semi-automatic welding machine, which improves the weld fastness, surface smoothness and processing progress of the skeleton.

3. Stop the self-cleaning system of the dust collector and confirm that the dust collector is always in good working condition.

4. Using high-quality components from around the world to improve equipment operation and reduce maintenance work.

Manufacturing requirements for dust collectors in mineral processing plants:

1. The design of the dust collector body is sealed and fastened, and the dimensional tolerance of the connecting parts meets the standard tolerance and the precision specified in the fitting.

2. The complete set of equipment for the dust collector in the beneficiation plant includes a spray system, a blockage air cannon, inlet and outlet duct matching flanges, fan inlet valves, fan shock absorbers, inlet and outlet soft connections and matching flanges, dust collector control cabinets, fan rain covers, escalator platforms, dust collector legs, and related detection instruments, meters, and signal display devices.

3. The production of wall panels requires flatness and no distortion, with a diagonal error of less than 5MM. During on-site installation, the vertical deviation of columns and wall panels should be less than 5MM, and any deformation of components during transportation needs to be corrected.

4. The perforation of the flower board adopts stamping technology, and the position is required to be accurate, with a deviation from the theoretical position not exceeding ± 1MM.

5. The thickness of the perforated plate is ≥ 6MM, the flatness of the plate is ＜ 1.5/1000, and the diagonal length error is ＜ 3MM. The punching process is used for processing.

6. Continuous welding adopts carbon dioxide protection airtight welding and conducts no leakage test.

7. The main components of the spray system will undergo pre assembly testing.

8. The cage bone of the dust collector is made by an automatic assembly line, with firm welding points, no burrs, protecting the cage bone and corrosion resistance.

9. The bag cage should be securely connected, have a smooth surface, and undergo performance stabilization treatment; The bag cage should be easy to disassemble and assemble, and the bottom of the installed filter bag should have appropriate spacing and should not come into contact with each other.

10. The top cover of the dust collector adopts a shear punch sealed top cover, which is suitable for manual opening in terms of weight and size.

11. The filter bag of the dust collector in the beneficiation plant should be easy to disassemble, have good sealing, high installation performance, be cut reasonably, and minimize seams. At the joint, the overlap width shall not be less than 10MM.

Cleaning and coating requirements for dust collectors in mineral processing plants:

(1) For metal shavings, broken cloth, crushed stones, and other foreign objects, they will be removed from the equipment. All iron filings, rust, oil, grease, chalk, crayons, paint, and other useless things are removed from the interior and exterior of the equipment. During transportation, keep the inside and outside of the equipment clean and dry.

(2) At the welding site, manual or mechanical cleaning methods are used according to standards for cleaning.
