1. System Overview
This production line is specially designed for fine powder processing, covering a fineness range of 80-3000 mesh, suitable for 10+ industries such as building materials, chemicals, and metallurgy, and can process non-flammable and explosive minerals (such as feldspar, calcite, talc, etc.) with a Mohs hardness of ≤8 and a water content of ＜6%. It adopts a modular design and supports customization of 2-50 TPH production capacity. The finished product has uniform fineness and an impurity rate of＜0.5%, meeting industrial-grade powder standards.
2. Core Process System
Crushing pre-processing module
Coarse crushing equipment: jaw crusher (feed ≤ 50mm, discharge ≤ 30mm)
Conveying system: bucket elevator + vibrating feeder
Intelligent pre-screening: humidity sensor real-time monitoring (humidity > 7% triggers drying alarm)
Grinding and grading module
Core grinder (four types optional):
| Machine type | Fineness range (mesh) | Applicable material hardness |
|---|---|---|
| Ball mill | 150 - 250 | High hardness ore |
| Raymond mill | 80 - 325 | Medium hardness mineral |
| HGM micro powder mill | 80 - 800 | Fine processing |
| Three-ring micro powder mill | 800 - 3000 | Ultrafine powder |
Dynamic classification system:
Multi-stage centrifugal classifier (accuracy ±5 mesh)
Variable frequency speed control fan (air volume 3000-20000m³/h)
Collection and purification module
Pulse dust collector: filtration efficiency ≥99.9%, emission<10mg>
Powder collection bin: anti-static design, equipped with pneumatic conveying system
3. Intelligent control system
Full process automation:
PLC central control: one-button start and stop, fault self-diagnosis
Real-time fineness control: through the linkage adjustment of the classifier speed and air volume
Energy Optimization System:
Power consumption monitoring per ton of powder (ball mill ≤35kWh/t, HGM mill ≤25kWh/t)
Hot air recycling (drying energy consumption reduced by 40%)

7. Selection Guide and FAQ
Q1: How to choose a grinding machine?
High hardness materials (Mohs 7-8): ball mill is preferred
Medium hardness fine processing: Raymond mill is selected
Ultrafine powder demand (＞1000 mesh): configure high-efficiency powder grinder + airflow classifier
Q2: How to deal with excessive humidity?
Integrated drum dryer (moisture content can be reduced from 15% to 1%)
Heat source optional gas/steam/electric heating (temperature adjustable 50-300℃)
Q3: How to adjust if the fineness does not meet the standard?
Classifier speed: Every increase of 100rpm will increase the fineness by about 50 meshes
System air volume: A 20% decrease in air volume will increase the fineness by 1 grade
