Cement, Ceramics, Stone Processing
A large amount of dust is generated in the raw material crushing, grinding, calcination, packaging and other links of cement production. The dust concentration is high (up to 1000-5000mg/m³), the particle size distribution is wide (0.01-100μm), and the proportion of silica-containing dust is high; the raw material mixing, forming and drying links of ceramic production generate clay dust with high humidity and strong viscosity; the cutting and grinding links of stone processing generate a large amount of quartz sand dust with coarse particle sizes (1-50μm) and concentrated emissions. The operating environment is mostly closed workshops or open-air workstations, and dust spreads over a wide range.
Inhalation of silica dust is the main cause of silicosis, and the incidence of silicosis in the building materials industry is among the highest in all industries;
Unorganized emission of high-concentration dust will cause air pollution in the surrounding area and be subject to key supervision by environmental protection departments;
Dust accumulation inside production pipelines and equipment can easily cause blockages and scaling, affecting production continuity;
Cement dust is easy to harden when exposed to water, which may lead to equipment failure or even collapse.
Large-Scale Pulse Bag Dust Removal + Pre-Dust Collection Solution
For high-concentration and coarse-grained dust (such as cement crushing and stone cutting), a two-stage purification solution of "pre-dust collection + main dust collection" is adopted. First, cyclone dust collectors are used to remove large-grained dust, and then enter the main dust collector to purify fine particles; for viscous dust (such as ceramic clay), heat preservation and anti-condensation devices are equipped.
Large-scale pulse bag filters, the filter bags select high-humidity resistant and anti-adhesive PPS filter materials, the pulse cleaning system selects high-pressure pulse valves, with high cleaning efficiency to avoid filter bag blockage;
Cyclone dust collectors, whose processing air volume matches the main dust collector, reducing the load of the main dust collector;
Sealed dust hoods are set at the discharge ports of production equipment, and the pipelines are made of large-diameter and wear-resistant materials to prevent dust blockage and wear.
For high-concentration and coarse-grained dust, wear-resistant filter materials (such as P84) are selected; for high-humidity and viscous dust, waterproof and anti-adhesive filter materials (such as coated PPS) are selected;
Equip 1.5 times the air volume according to the dust generation amount to avoid high-concentration dust exceeding the equipment processing capacity;
Pulse cleaning is preferred, with high cleaning efficiency, suitable for high-concentration dust, avoiding filter bag blockage;
Insulation layers and heating devices are equipped in high-humidity environments to prevent dust condensation from blocking pipelines and filter bags.

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.
