Since the 1980s, with the development of the national economy, more and more industries need to do dry ultra -fine powder grinding of materials. The airflow crusher is one of the most effective equipment for powder ultra -fine powder grinding. Essence In my country, after 20 years of development, the airflow crushing machine industry has been widely used in pesticides, food, medicine, fine chemicals, electronic battery materials and other fields.
The airflow crushing machine is reasonable, run stable, low energy consumption, large crushing capacity, small volume, no failure, convenient cleaning and maintenance. Generally, the shell uses water cooling and the air volume generated by itself, transports powder materials, has a low temperature, and thermoltage material can also be crushed. By using a large amount of ultrasonic vortex caused by the back of the blade back and high -frequency pressure to reduce the wear of the blades. The structure is compact and there is no dust overflow.
The principle and characteristics of air flow crusher: When the compressed gas enters the crushing room through the feeding sprayer, crushed the raw material into the crushing room, there are multiple crushing nozzles on the periphery of the crushing outdoor, and the spray supersonic airflow is Crossing each other, crushing and crushing, the crushing tube separates the thick particles, and the thick particles circulate return to the crushing room to continue crushing. After the internal axic circulation is crushed, the uniform super fine powder can be obtained at the outlet. 1. Suitable for dry super micro -process. Due to the high impact speed, it can reach Mach 2.5 or more. Generally, it is easy to get 1-10 microns particles. According to the nature of the material, you can also get less than 1 micron particle. 2. Due to the inner closed-circuit crushing mechanism inside the crusher machine, the thickness in the product is rough in the product The particles are constantly looping and crushing, so they can obtain products with uniform particles and small particle size distribution range. 3. The device has the advantages of short crushing time, simple structure, convenient operation and maintenance, small area, low noise (72 decibels) and no vibration. 4. High efficiency when crushing, continuous crushing, and the purity of crushing products.
Case Sharing of the Powder Flow Character of the Powder Powder of Youmingke: a mechanical equipment company, the company mainly produces pharmaceutical equipment and powder automation equipment, and represents imported related equipment in the United States and Germany. The cohesion of the team has developed rapidly and broke the monopoly of foreign equipment in the industry. Case parameter: product particle size: D90: 2-80um Hours: 50-80kg
During the production process At the time, the operating parts drive the air to produce a \"whistle\" call: (2) the device is running. The sound of vibration; (3), the friction between the turntable or the hammer and the drug; the friction sound of the rotating part itself. For the reasons for noise, the main solutions are as follows: (1) Add lubricating oil to each rotating part. If the bearings and axis are dislocated, adjust the bearing wear and replace the bearings; , And cool through the crushing room water cooler, the intake port of the muffler is installed in the crushing room; (3) the vibration reduction of the equipment and other equipment.
Breakthroughs in key technologies such as crushing machines, classifiers, and key technologies independently developed by Youmingke, as well as key technologies such as plastic surgery, covering, and modification, breaking the barriers of foreign technology, filling the gap in the domestic industry, and greatly promoting medicine and food, Chemical, minerals, new materials, solid waste treatment and other fields of technological progress and industrial upgrading.He has won honorary titles such as the Ministry of Science and Technology's \"Technology Innovation Fund for Science and Technology SMEs\", \"First Batch of Gazelle Enterprises in Shandong Province\", \"Shandong Provincial Hidden Champions Enterprise\", \"High -tech Enterprise\", \"China Patent Shandong Star Enterprise\" and other honorary titles.
