Answer: There are two main types of hot air flow in the drying oven:
(1) Natural convection. The natural circulation convection of hot and cold air is used to make the temperature inside the box uniform. After the electric furnace wire is energized, the heat is released, the air at the bottom of the box becomes hot, the hot air rises lightly, the cold air drops, and the air in the box is convected to make the temperature inside the box uniform. If the venting holes at the top of the drying box are properly adjusted, the temperature uniformity is good.
(2) blast convection. By using a small electric blower to increase the circulating convection of the air from the inside of the inside of the drying box, the temperature in the drying box is more uniform, and the general temperature difference does not exceed 0.5 Â°C. Quality coal is used laboratory convection blast drying oven.
It can fit 1~ 8 layers of sieve with a lid and pan.
The Test Equipment can be used to sieve the water content and sticky materials, an ultrasonic set can be added to work together.
Voltage is commonly 220v- 230v / 50 HZ, can be adjustable.
1. Portable sieve, Easy to install and remove, and easy to cleanup
2. Highly control the sieving granularity scale,
3. Excellently improve sieving effect.
4. Screening precision can raise to 1~99%, the timer can be adjusted from to 1 second - 99 mibutes.
5. evenly and consistent aperture, mesh have no wire broken.
6. Durable, have Long use life,
