Vacuum drying of industrial dehumidifiers has also entered the field of plastics processing. For example, vacuum drying equipment developed by Maguire in the United States has been applied to plastics processing. This continuous operation type machine consists of three chambers mounted on a rotating conveyor. At the first cavity, when the colloidal particles are filled, a gas heated to a drying temperature is passed to heat the colloidal particles. At the gas outlet, when the material reaches the drying temperature, it is moved into the second evacuated cavity.

Since the vacuum lowers the boiling point of the water, moisture is more likely to become vaporized out of the water vapor, and therefore, the moisture diffusion process is accelerated. Due to the presence of the vacuum, a greater pressure difference is created between the interior of the rubber particles and the surrounding air. Under normal circumstances, the residence time of the material in the second cavity is 20min to 40min, and for some materials with strong hygroscopicity, it needs to stay at most 60min. Finally, the industrial dehumidifier material is sent to the third chamber and is thus removed from the dryer.

Industrial dehumidifier adopts the principle of dehumidification, simple operation, low energy consumption, low cost, complete functions, convenient maintenance, adopts full computer control system, and is simple and reliable to use. Industrial dehumidifiers use scroll compressors: Japan Daikin (international brands, high energy efficiency ratio); Humidity sensor: Japan Shinsei (import); Fan: The use of industrial ventilation professional external rotor fan (long life, low noise, A large amount of air.)

Industrial dehumidifiers use the same energy for heating plastics in dehumidified gas drying and vacuum drying. Both methods are performed at the same temperature. However, in the vacuum drying of industrial dehumidifiers, gas drying itself does not require energy consumption, but it requires the use of energy to create a vacuum. The energy consumption needed to create a vacuum is related to the amount of dried material and the amount of moisture.

Gravitational Gold Concentrator

It is suitable for the recovery of single gold in placer gold, vein gold mines and polymetallic mines, instead of mercury plate operations. The addition of large single gold particles in the collected ore before flotation can further increase the recovery rate of gold mines, and it can also be used from gold-bearing mines. Separate single gold from flotation gold-copper concentrate and flotation gold concentrate.The device has the following characteristics:

1.Wide application field: the device can regenate various types of activated carbonon by adjusting the angle and rotational speed of furnace pipe.

2.Regeneration activated carbon in the oven retention time 40 minutes, which is applicable to the regeneration levelofall kinds of grain particles, for coal activated carbon also has good regeneration effect.

3.High degree of automation:the device operation achieves automatic control,with man-machine interface+Intelligent instrument control,reduces the operating workers and the labor intensity is low.

4.High recovery rate of Iodine value:basically returned to a new carbon levels above 90%.

5.Low carbon loss:≤1-2%(Coal carbon)But slightly higher than the JHR-O series activated carbon fuel diesel reclamation equipment

6.Easy installation, covers an area slightly larger, but the small space height requirements, large installed power.

Long service life:The core components furnace tube using thick wall (10 mm thick) 1200 ℃ high temperature resistance, corrosion resistant special stainless steel pipe.
