Mining dust filter cartridges – 1400–2200 g/m² capacity.

1. Overview of Mine Crushing High-Concentration Dust

Aite Dust Filter Cartridges for High-Dust Mining Crushing Conditions are

 exclusively developed to withstand harsh abrasive mine dust generated by

 jaw crushers, cone crushers, impact crushers, and vibrating screening

 equipment. Mine crushing stations generate ultra-high concentration mineral 

dust ranging from 1000 mg/m³ to 3500 mg/m³, consisting of mixed hard sharp 

coarse rock fragments, submicron silicate fine powder, and agglomerated dry

 mineral particles. Compared with ordinary industrial dust, mine dust features

 three distinctive properties: high abrasion hardness, wide particle size 

distribution (1–80μm), and easy compaction into dense dust cakes under

 airflow impact.

Dust holding capacity refers to the maximum mass of test dust that a filter 

cartridge can stably capture before reaching the set final differential pressure

 threshold, quantified in g/m² of effective filter media area. Aite Dust Filter

 Cartridges for High-Dust Mining Crushing Conditions directly determine

 maintenance interval, equipment downtime frequency, and overall operation

 cost of mine dust removal systems. Low dust holding capacity ordinary filter

 cartridges reach the 600–800 Pa replacement differential pressure within 

only 7–15 working days, requiring frequent shutdown replacement. 

High-capacity mine-specialized pleated filter cartridges adopt gradient density 

composite media, optimized wide-shallow pleat layout, and reinforced support 

structure – boosting unit-area dust holding capacity by 50%–120% versus 

standard general filter cartridges.

As a professional manufacturer specializing in industrial dust filtration 

equipment, we deliver Aite Dust Filter Cartridges for High-Dust Mining

 Crushing Conditions with stable performance, reliable construction, 

and competitive pricing for mining facilities worldwide.

2. Standard Definition & Test Calibration Parameters

Official Quantitative Definition: Dust holding capacity (DHC) is the total mass 

of standardized ISO A3 mineral test dust retained on filter media when

 differential pressure rises to the industry-specified final limit of 800 Pa under

 fixed rated airflow.

DHC (g/m²) = Total captured dust mass (g) ÷ Total effective filtration area of

 cartridge (m²)

Test Bench Standard Conditions:

· Test dust: ISO A3 silica-rich mineral mixed dust

· Constant surface wind speed: 0.5 m/min

· Final differential pressure cutoff threshold: 800 Pa

· Pulse cleaning interval: 8 minutes, blowing pressure 0.5 MPa

above 20μm, forms loose primary dust cake

· Middle transition fiber buffer layer (250 g/m²): Uniformly distributes airflow,

 reserves intermediate storage space

· Inner dense fine capture layer (300 g/m²): Intercepts submicron silicate fine 

dust below 5μm

Pleat Geometric Structural Parameters:

Parameter Standard

Pleat Spacing ≥8 mm per fold, 22–28 pleats per meter

Pleat Depth 30–38 mm shallow pleat design

Pleat Vertex Angle 50°–60° obtuse angle layout

Single Cartridge Size φ325×900 mm, φ350×1000 mm

5. Stepwise Matching Rules

Step 1: Measure on-site dust concentration, ore hardness, and dust moisture 

content

Step 2: Select filter cartridge static dust holding capacity grade corresponding

 to load

Step 3: Calculate total required filtration area based on system air volume and 

safe wind speed

Step 4: Optimize pulse cleaning parameters and install front pre-separation 

equipment

Working Condition Recommended Configuration Wind Speed Pulse Cycle

Small jaw crusher, limestone, <1200 mg/m³ 1400–1600 g/m² light-load coated

 0.5–0.6 m/min 10–15 min

Multi-stage crushing, iron ore, 1200–2200 mg/m³ 1600–1900 g/m² universal 

gradient 0.4–0.5 m/min 6–9 min

Open-pit, quartz granite, >2200 mg/m³ 1900–2200 g/m² heavy-duty 

wide-shallow ≤0.35 m/min 3–5 min

7. Common Capacity Mismatch Fault Analysis

Fault 1: New cartridge reaches 800 Pa within 10 working days

· Root Causes: Low dust holding capacity ordinary cartridge; surface wind

 speed exceeds 0.6 m/min; missing front coarse dust pre-separation

· Solutions: Upgrade to 1600 g/m²+ gradient composite cartridges; add extra

 cartridges to reduce wind speed; install labyrinth dust baffle

Fault 2: Laboratory capacity 1800 g/m², field actual only 900 g/m²

· Root Causes: Pulse cleaning pressure too low or cycle too long; compressed 

air contains oil and water; narrow deep pleat structure

· Solutions: Adjust pulse pressure to 0.5–0.6 MPa; shorten cleaning cycle; 

install cold dryer and oil-water separator; replace with wide-shallow pleat 

cartridges

8. Frequently Asked Questions (FAQ)

Q1: Why do gradient composite media mine filter cartridges have much higher 

dust holding capacity?

A: Aite Dust Filter Cartridges for High-Dust Mining Crushing Conditions use

 three-layer gradient fiber that realizes layered interception of coarse and fine 

mineral dust. All dust accumulates on the outer PTFE membrane surface 

without deep embedding into substrate pores, fully utilizing pleat internal 

storage space.

Q2: What static dust holding capacity grade must be selected for open-pit 

quartz granite ultra-high concentration crushing lines?

A: Heavy-duty grade with static dust holding capacity 1900–2200 g/m² 

wide-shallow pleat gradient PTFE composite cartridge is required, with wind 

speed strictly controlled ≤0.35 m/min and front labyrinth coarse dust baffle.

Q3: Can blocked mine high-capacity filter cartridges be washed to restore 

original dust holding capacity?

A: Strictly prohibited. Mineral dust mixed with water solidifies into irreversible 

hard blocks inside pleats, permanently occupying dust storage space. 

Only maximum 2 times low-pressure internal reverse blowing emergency

 cleaning is permitted.

Q4: What is the standard test dust used for dust holding capacity testing?

A: ISO A3 silica-rich mineral mixed dust simulating granite, iron ore, 

and limestone crushing dust with high quartz content is used for testing Aite 

Dust Filter Cartridges for High-Dust Mining Crushing Conditions.

Q5: What is the final differential pressure cutoff threshold for mine dust 

collectors?

A: The final differential pressure cutoff threshold is 800 Pa – the mandatory

 replacement limit for mine dust collectors using Aite Dust Filter Cartridges for

 High-Dust Mining Crushing Conditions.

Q6: What pulse cleaning parameters are recommended for quartz granite 

ultra-high concentration crushing?

A: For quartz granite ultra-high concentration crushing, pulse cycle should 

be 3–5 minutes with blowing pressure 0.50–0.60 MPa – preventing dust cake

 compaction and maintaining effective dust holding capacity.

Q7: How does dust moisture content affect effective dust holding capacity?

A: Mine dust with moisture above 6% forms sticky mud-like agglomerates after

 deposition that cannot be fully stripped by pulse cleaning. Dry crushing lines

 with moisture below 3% maintain maximum rated dust holding capacity.

Q8: What is the recommended pleat spacing for mine filter cartridges?

A: Aite Dust Filter Cartridges for High-Dust Mining Crushing Conditions use

 pleat spacing ≥8 mm per fold with 22–28 pleats per meter. Narrow pleats 

below 6 mm rapidly form dust bridges after short operation, cutting effective

 capacity by over 50%.

Q9: What documentation is provided with the filter cartridges?

A: Each shipment includes EN 10204 material certificates, ISO 16889 filtration

 performance test reports, dust holding capacity test reports, dimensional

 inspection records, and factory quality certificates.

Q10: Can Aite Dust Filter Cartridges for High-Dust Mining Crushing Conditions

 be customized?

A: Yes. Custom options include special media grades, pleat geometries,

 dimensions, and surface treatments based on specific mine dust characteristics 

and operating conditions.

Q11: What is the recommended maintenance for the compressed air source?

A: Weekly compressed air source inspection is recommended – draining 

oil-water separator residual water and oil. Oil-containing pulse airflow forms 

sticky dust mud on media surface, permanently reducing effective dust holding 

capacity.

Q12: Can I order samples before bulk purchase?

A: Yes. We support paid sample orders with production lead time of 

approximately 7–10 days. Sample costs are fully deductible from your first bulk 

order upon approval.
