Excavation, Crushing, Transportation
A large amount of rock dust and coal dust are generated during the excavation of coal mines, iron mines, non-metallic mines, etc. The dust concentration is extremely high (2000-10000mg/m³), the particle size is coarse (5-100μm), and the silica content is high; the dust spreads over a wide range in the crushing, screening and belt transportation links. The operating environment is mostly open-air or semi-open-air, which is greatly affected by natural environments such as wind speed and humidity; some mines have combustible gases such as gas, which are more risky when mixed with dust.
Silicosis and coal worker's pneumoconiosis are high-incidence occupational diseases in the mining industry, which seriously threaten the life and health of workers;
The mixture of coal dust and gas is prone to gas explosions, and the accumulation of rock dust may lead to collapse accidents;
Unorganized dust emission from open-air operations will cause regional air pollution and affect the lives of surrounding residents;
High-concentration coarse-grained dust will aggravate equipment wear and lead to frequent failures of crushers, conveyors and other equipment.
High-Negative Pressure Large-Scale Dust Removal + Gas Linkage Solution
For underground excavation links, a combined solution of local fans and dust removal fans is adopted to purify underground dust; for ground crushing and transportation links, large-scale central dust collection systems are adopted; for gas-containing mines, the dust removal system is linked with the gas monitoring system to ensure safety.
Mine dust removal fans, selecting high-negative pressure and large-air-volume models, equipped with waterproof and explosion-proof functions, and the filter materials select wear-resistant and flame-retardant materials;
Large-scale pulse bag filters, the filter bags select high-temperature resistant and dust wear-resistant P84 filter materials, matched with large-scale cyclone pre-dust collection devices;
Gas concentration monitors, which automatically cut off the power supply of the dust removal system and start explosion-proof plans when the gas concentration exceeds the standard.
Equipment and pipelines are made of wear-resistant materials (such as wear-resistant steel plates and ceramic liners) to cope with the wear of high-concentration coarse-grained dust;
Underground equipment must have explosion-proof and waterproof functions, meeting mine safety standards;
Ground equipment is equipped with 2 times the air volume according to the dust generation amount to ensure that dust is collected quickly and avoid diffusion;
Linked with the gas monitoring system, it automatically shuts down when the gas concentration exceeds the standard to ensure safety.

Answer: It can be judged in two ways: ① Third-party testing: Entrust a qualified environmental protection testing agency to test the dust concentration at the equipment outlet to ensure compliance with relevant standards such as the "Integrated Emission Standard of Air Pollutants" (GB 16297-1996); ② Equipment monitoring: Select equipment equipped with dust concentration monitors to view the real-time dust concentration data at the outlet and intuitively judge the purification effect.
Answer: The maintenance cost of dust removal equipment is relatively low, mainly including three parts: ① Accessory replacement: Filter materials (filter bags, filter cartridges) are the main wearing parts. The replacement cycle depends on the working conditions (generally 3-12 months). The replacement cost of high-quality filter materials accounts for about 5%-10% of the total equipment price; ② Energy consumption cost: The fan operates with electricity. Our equipment adopts high-efficiency and energy-saving fans, and the energy consumption is 15%-20% lower than the industry average; ③ Labor cost: Daily cleaning of accumulated dust and equipment inspection are simple operations that do not require special personnel on duty, resulting in low labor costs.
Answer: We ensure safety through "triple protection": ① Equipment explosion protection: Select motors, fans and electrical components with explosion-proof grades meeting industry standards, and the equipment shell adopts an explosion-proof design; ② Explosion suppression: Equipped with explosion vents, flame arresters and explosion suppression devices. Explosion vents can release pressure in an instant during an explosion, flame arresters prevent the spread of explosion flames, and explosion suppression devices can quickly extinguish explosion flames; ③ Monitoring and early warning: Equipped with dust concentration, temperature and pressure monitors to monitor the equipment operation status in real time. When parameters are abnormal, it automatically warns and shuts down to avoid danger.
Answer: The installation cycle depends on the project scale. Small-scale decentralized equipment (such as mobile welding fume purifiers) is simple to install and can be completed in 1-2 days; the installation cycle of large-scale central dust collection systems is about 7-30 days. We will communicate with customers in advance to formulate a reasonable installation plan, and try to choose production gaps and holidays for installation to reduce the impact on normal production; for large-scale projects, phased installation and commissioning can be adopted to ensure the normal operation of some production lines.
Answer: Universal use is not recommended. The dust working conditions (concentration, particle size, physical and chemical properties) of different industries are quite different. For example, heavy metal dust in metal processing, flammable and explosive dust in the chemical industry, and ultra-fine dust in the electronics industry have completely different requirements for equipment filtration precision, explosion-proof performance and material. Universal equipment cannot accurately adapt to working conditions, which may lead to substandard purification effects, equipment damage and even safety accidents. We recommend customizing exclusive equipment according to the specific industry working conditions.
Answer: If a fault occurs in the equipment, it can be handled in the following steps: ① Emergency shutdown: In case of serious faults (such as abnormal noise, peculiar smell, dust leakage), immediately cut off the equipment power supply to avoid expanding the fault; ② Contact after-sales service: Call our 24-hour after-sales hotline to explain the fault phenomenon, equipment model, working conditions and other information; ③ On-site processing: Technical personnel from nearby service outlets will arrive at the scene within 2-8 hours to troubleshoot and repair; ④ Emergency support: For key production links, we can provide temporary backup equipment to ensure uninterrupted production.
