Spray Dryer Atomizer Description

High-speed centrifugal atomizer is high-speed centrifugal spray drying heart, including high-speed motor, spindle, nylon block, large coupling plate, bearings and spray disk, etc., by connecting the motor shaft couplings and soft nylon block nebulizer spindle spindle motor vibration and atomizer spindle and do not pass, the nebulizer for flexible shaft spindle rotating at high speed when the resonance region, nebulizer spindle will rotate as stable as gyro, high-speed motor is provided with a water-cooled jacket and spray lubrication, nebulizer spindle lubricating oil circulation. Which has a higher speed, smooth running, small vibration, long life, simple operation, and can be widely used in high-speed spray dryer, the liquid spray dried into a powder material is applied to the finished product, and other industrial fields.

High-speed centrifugal atomizer is a core component of centrifugal spray dryer; Our company specializes in the production of high-speed centrifugal atomizer, elected on the basis of absorbing foreign technology, based on independent research, computing, manufacturing, won the praise of domestic households. We could provide different specifications, different materials, different shapes of cntrifugal disk;



Spray Dryer Atomizer Working Principle

After the filtering and heating, the air enters into the air distributor on the top of the drier. The hot air enters into the drying room in the spiral form and uniformly.

By passing through the high-speed centrifugal spray on the top of the tower, the material liquid will rotate and be sprayed into the extremely fine mist liquid beads. Through the very short time of contacting the heat air, the materials can be dried into the final products.

The final products will be discharged continuously from the bottom of the drying tower and from the whirl separator. The waste gas will be discharged from blower.

The liquid material becomes very fine drops under the centrifugal force in the equipment, enlarging enormously the surface area of the material. It forms instantly the dried products once these drips contact with hot air. This process has advantages such as dry at high speed, high efficiency, easy operation, the output products keep the original quality, good fluidity, good solubility, high purity and environment friendly.





Spray Dryer Atomizer Features

Pneumatic type atomizer

A turbine wheel is arranged on the main shaft, and drive the turbine wheel through the compressed air to drive the main shaft to rotate, so as to make the atomizing disc high-speed rotation.

The atomizer by adjusting the compressed air pressure and air volume to achieve stepless speed change, it has features with small mechanical wear, simple structure, convenient maintenance. Compressed air pressure in the 0.2 ~ 0.6Mpa, suitable for evaporation capacity is less than 5kg/h

Electric type atomizer

Electric high speed centrifugal atomizer is my company's own design, manufacture of mechanical and electrical products, power 250W-30KW, speed in 8000-40000 / min stepless speed regulation
1,Stepless speed control, according to the characteristics of the raw material, and choose the best speed
2,High speed motor directly driving spray disk, small vibration, uniform spray, low noise.
3,Power with the load on its own regulation, energy saving, low temperature rise, stable performance.
4,Compact in structure, small in size, light in weight, easy to operate, clean and maintain
5,Compound electric spray nozzle adopts water cooling, air cooling at the same time, and according to the need to choose the grease lubrication and oil lubrication, more

Suitable for high temperature environment, at the same time with the water, gas, over-current, over temperature alarm and other functions, more stable performance.

Mechanical type atomizer

Mechanical centrifugal atomizer is centrifugal atomizer is the most widely used structure form, is divided into specific gear and gear belt transmission. Transmission gear is a gear driven by the. Gear ratio is different, the rotational speed of the spindle is also different, in material feeding quantity fluctuation, constant speed, higher mechanical efficiency for for a long time continuous, large-scale spray drying.

In order to ensure the normal use of the atomizer, large and medium-sized mechanical centrifugal atomizer is provided:

1. Oil security system: once appear to lack of oil or oil fault, safety system automatically start, and disconnect the main motor, protect the atomizer.

2. Digital monitoring system of atomizer operation (oil pressure, oil temperature, oil level detection) real time digital data.

3. Cooling system: in order to discharge the atomizer as a mechanical transmission and drying process of incoming heat. Large and medium-sized atomizer are installed cooling system, cooling methods mainly water and gas cooled. Water cooled requirements has good tightness.
