Here is the English translation of "简介": **Introduction**
The entire process of this system employs an effective combination of dust collectors, induced draft fans, suction tanks, and pneumatic conveying systems, along with strict control over each dust emission point. By using high-quality filtration materials, it ensures that dust emissions are kept below 40 mg/m³, and can reach 20 mg/m³ after operation. This prevents dust from escaping, and the entire production process operates under negative pressure, ensuring cleanliness and environmental friendliness.

Based on our experience, it is not feasible to use a single noise control device to manage multiple pieces of equipment. Our company employs a special design that minimizes noise through vibration reduction and partial flexible connections. Effective noise reduction can only be achieved by measuring the overall noise after the entire production line has been commissioned. The *** method is to use walls and soundproofing materials.

Main Equipment Features:

Ball mill:
Designed strictly in accordance with the processing requirements for ultra-fine filler-grade minerals.
Optimized the length-to-diameter ratio of the ball mill.
The grate-type mill tail discharge ensures smooth material output without mill swelling, and the cylinder does not require cooling.
The grinding media should be proportioned reasonably according to product requirements, with a high filling rate and high efficiency.
Optimized the matching of drive and grinding energy consumption, **maximizing energy savings**.
It forms a closed system with the classifier, using negative pressure conveying, resulting in no dust.

Classifier
Horizontal direct-drive or belt-driven multi-rotor classifier
Precise process control ensures **vertex cutting
Adjustable flushing airflow improves classification efficiency.
The material directly enters the classification zone without being contaminated by the coarse powder after classification.
Optimize rotor design to achieve low energy consumption.
The particle size distribution of the product can be adjusted through different arrangements of the classifier to meet the technical requirements of various products.

Quantitative System:
The feeding of the ball mill adopts a precise quantitative system, ensuring stable feeding even when the material density changes.
The feeding of the classifier adopts a precise quantitative system and is interlocked with the discharge of the ball mill, ensuring the stability of system operation and product particle size.
High-precision metering pumps inject grinding aids into the mill with precise timing and dosage, based on the required product fineness.
The airflow control valve is equipped with an airflow measurement system, which can regulate the flow of staged air. Both the material bin and product bin are fitted with level indicators, enabling automatic control of the entire production line through PLC control. A light flow chart displays operation and error statuses clearly, making it easy to operate.

Environmental Protection and Noise Control:
Dust is treated with coated filter bags, with emissions below 20 mg/m³.
Use efficient silencing devices to ensure exhaust noise < 80 dB(A).
No wastewater is discharged; only the cooling water for the ball mill bearings is used, which can be recycled.

Application Scope:
Calcite, marble, limestone, barite, kaolin, slag, fly ash, ultrafine cement, quartz, alumina, etc.
