Operation Principle of the Pendulum Grinding Mill System

The bulk material is broken by the Jaw crusher to a certain size (powdery or fine particles can not pass through the Jaw crusher), and the material is conveyed vertically to the hopper by a bucket elevator. Then, the electromagnetic vibration feeder delivers the materials quantitatively, evenly and continuously into the main machine for grinding. The pulverized fines are carried out by the blower’s airflow and graded by an analytical machine placed above the main engine. Suitable fine powder that meets the requirements will be entered into the large cyclone separator with the air flow. After separation, the powder will be discharged through the discharge pipe, that is a qualified product. The air flow enters the blower by the return duct at the upper end of the cyclone separator. The whole airflow system is closed loop and operates under negative pressure. Because the grinding material contains moisture, when milling the moisture will evaporate into gas. That gas then leaks in each connection of the whole pipe, which makes an increase in the volume of air in the circulating air stream.

This increased air volume will be introduced into the small cyclone separator from the air duct between the blower and the main engine. The fine powder with the air flow is collected by the small cyclone separator. Then it will be discharged by another outlet pipe. The gas will be discharged into the atmosphere through the exhaust pipe of the upper end of the small cyclone separator.

The vertical grinding machine is a kind of advanced grinding equipment designed and developed on the basis of the extensive use of advanced technology at home and abroad, combined with many years of various mill machine production experience. It is an ideal equipment for grinding industry, which integrates crushing, drying, grinding and grading transportation. It can be widely used in cement, electric power, metallurgy, chemical industry, nonmetallic mineral industry and so on. It is used to grind lump, granular and powdery raw materials into the required powder materials.

The main structure of the vertical grinding machine
Vertical grinding machine mainly consists of powder separator, grinding roller device, grinding disc device, the pressure device, reducer, motor, shell and so on. The separator is a highly efficient and energy saving powder separator. Grinding roller is used to crush and crush materials. The millstone is fixed on the output shaft of the reducer and is the place where the grinding roller compacts the material. The pressurizing device is a component for grinding roller to provide enough pressure to crush material. So it is also called high pressure grinding mill.

Working principle of the vertical grinding machine
When the vertical grinding machine is working normally, the motor drives the grinding disc to rotate through the reducer, and the material falls from the feed inlet to the center of the grinding disc through the lock air feeder. With the rotation of the grinding disc, the material moves to the edge of the grinding disc under the action of the centrifugal force. Through the ring groove on the grinding disc, the material is crushed by the roller rolling. The crushed material is brought up at the edge of the grinding disc by high-speed airflow from the wind ring and the large particles fall directly onto the grinding disc to re-ground. When materials in the air flow pass the upper separator, under the action of rotating rotor, the coarse powder falls from the cone bucket to the grinding disc and is re-ground. The qualified fine powder goes out with the airflow and is collected by the dust collecting device, that is, the product. Materials containing moisture are dried in contact with hot air flow. By adjusting the hot air temperature, it can meet the requirements of different humidity materials and achieve the required product moisture. By adjusting the separator, the required thickness of different products can be achieved.

Main features of the vertical grinding machine
1.Low investment cost
Due to the integration of crushing, drying, grinding and grading, the system is simple and the layout is compact. The area is about 50% of the ball milling system, and it can be arranged in the open air. Therefore, the investment cost can be reduced greatly.

2.Low operating cost
(1)High grinding efficiency : using the grinding roller to directly crush the material on the grinding disk, low energy consumption, and 30% ~ 40% less energy consumption than ball grinding system.
(2)Less abrasion: longer service life and less wear due to the fact that the grinding roller does not contact the grinding disc directly during work and that the grinding roller and the lining plate are made of high quality materials.

3. Strong drying ability
Because the hot air directly contacts with the material in the grinding, it has strong drying ability and saves energy. By adjusting the hot air temperature, it can meet the requirements of different humidity materials.

4. Easy operation
(1)The system is equipped with automatic control system, which can realize remote control and easy operation.
(2) Vertical grinding machine is equipped with equipment to prevent direct contact between roller sleeve and disc liner to avoid destructive impact and severe vibration.

5. Stable product quality
Because the material stays in the grinding for a short time, it is easy to detect and control the product granularity and chemical composition, reduce the repeated grinding, and stabilize the product quality.

6. Convenient maintenance
Overhauling the oil cylinder, turning the rotating arm, replacing the roll sleeve and liner plate is convenient and quick, reducing losses in downtime.

7. environmental protection
Vibration is small, noise is low, and the whole equipment is sealed, the system works under negative pressure, no dust spillover, clean environment, and meets the national environmental protection requirements.

The process flow of the vertical grinding machine
According to the location of humidifying tower and dust collector, the vertical grinding machine has two different layout schemes, namely, the three fan system and the double fan system. A cyclone collector is used for the collection of products. This arrangement reduces the working negative pressure of the system and the amount of gas passing through the dust collector. The electric dust collector can also be replaced by the bag dust collector as the final dust collector. The dust collector can be the electric dust collector or the bag collector, and the grinding gas is directly entered into the dust collector. The system reduces the number of equipment and simplifies the system configuration.

The powder is discharged by the discharging grate plate to finish the grinding operation.

Standard discharge, reclaimed water reuse and zero effluent discharge

1. As for paper mill wastewater treatment, pulping wastewater is the most difficult wastewater to be treated in the papermaking industry. The organic pollutants and inorganic salts are high in content, complex in composition, high in hardness, high in costs. The technical staff of JIUWU work with experts from the Institute of Membrane Science and Technology of Nanjing Tech University and develop successfully membrane technology as the core of zero effluent discharge process or zld (zero liquid discharge).

2. Using the process of pretreatment, membrane integration, evaporation crystallization and other related processes turns waste into valuable and achieves the sewage recycle. The project forms a major technological breakthrough in the field of wastewater treatment of pulp and paper.

Application background

• Industrial water prices continue to rise
• Industrial water intake limit
• Increased emission water quality standards (COD, TOC, etc)
• Enforcement requirements for environmental protection and water reuse rate, etc.
• Large demand for fresh water
• Large amount of wastewater discharge
• The composition of wastewater is complex, and the content of organic pollutants and inorganic salts is high.
