The basic working principle of the ultrafine powder dryer is the high crushing ability of the high-speed stirrer, and the classifier's control over the particle size of the material and the re-crushing effect on the secondary agglomeration. The relative flow between the swirling airflow and the material particles is greatly opposed. Movement, thereby strengthening the principle of heat and mass transfer to complete the drying of the material. Its unique advantages are the bottom-mounted high-speed crushing device and the top adjustable grading device, which can easily control the product's particle size; its structure is more advanced and maintenance and maintenance are more convenient. So that the ultrafine powder dryer has a stronger crushing and dispersing ability, which is very suitable for the drying of ultrafine materials.
Ultra-fine powder dryers can be used for bulky or less viscous materials, especially those with secondary agglomeration. Ultrafine powder dryers work better when applied to these materials. Through the modification of the rotor structure and the control of the drying air flow, nano-ultrafine powder dryers can be applied to the drying of organic materials such as nitrile rubber.
The ultrafine powder dryer has been successfully applied to the drying of materials such as nano calcium carbonate, nano aluminum hydroxide, micro powder aluminum hydroxide and nano magnesium hydroxide. As the nano-materials are in the wet state, the strong surface binding force makes the materials have a great viscosity, resulting in the material agglomeration, poor fluidity, difficulty in transportation, and difficulties in drying. In the drying process, this binding force causes the material to agglomerate, affecting the product performance. Therefore, during the drying process, materials should be prevented from bridging and the agglomerated materials should be effectively dispelled. In addition, nanomaterials generally contain modifiers, whether organic or inorganic, easily decomposed by heat. Therefore, the thermal sensitivity of the material must be taken into account when drying nanomaterials. Ultrafine powder dryers are able to adapt to the drying characteristics of nanomaterials and have a very good drying effect.
Drilling machine is a complex machine consisting of a machines, units and mechanisms, it is a mechanical equipment in the development of exploration or mineral resources (including solid, liquid, gas, etc.) to drive Drilling Tools into underground and obtain physical geological data. Drilling machine is also called drilling rig. The main function is to drive the Drill Pipe to break bottom rock and to drill down or put in the hole. Drilling machine can be used to drill cores, ore cores, cuttings, gaseous samples and liquid samples, so as to identify underground geology and mineral resources. And also used to drilling water wells.
