Briefly speaking, the airflow pulverizer and similar models of Shandong Erman production are.
Ultra-micro gas flow grinding is to overcome the internal cohesive force of the solids in the internal cohesion of the solids by mechanical or fluid power, thereby pulping 3 mm or more of the material particles to 10-25 microns. It was a high-tech of a material processing that was generated by the development of modern high-tech after the 1970s.
Many cheap mineral products, chemical products have increased with ultrafine crushing, and its value increases with the application range, and the added value is less than a few times even more than ten times. At present, there are many equipment capable of ultrafine pulverization, including airflow pulverizing machine, mechanical impact mill, ball mill, Raymond mill, and glow machine, and airflow pulverizer is recognized to effectively obtain minimum particle size ultrafine powder. Equipment, is also the most commonly used equipment in powder processing.
The airflow pulverizer is an indispensable means of modern powder processing industries. It not only makes ultrafine powder, but also the particle size distribution of the product is narrow, and the product dispersibility is good. Advantages of high activity, no metal pollution. Welcome range of airflow pulverizer:
can be widely used in chemical, metallurgy, mining, energy, electronics, pharmaceutical, pesticide, plastic, paper, pigment, paint, dye , Abrasive, food, cosmetics and other industries, as well as some special materials such as: polymer materials, advanced electric porcelain materials, magnetic materials, semiconductor materials, fine chemical powder products, catalysts, reagents and chemicals, propellants, etc. High purity powder Ultrafine pulverization of the product.
Working principle of the airflow pulverizer:
The material is fed into the chain tube through the screw feeder, and the medium cylinder is sent to the pulverizing chamber, and the compressed air is generated by pulverizing the nozzle. The supersonic jet flows in the lower portion of the pulverizer to the heart inverse spray flow field, under the action of the differential pressure, so that the bottom material of the mill is fluidized, the accelerated material is integrated in the intersection of the multi-nozzle, producing a dramatic impact Collision, friction and pulverize. The pulverized material moves with the rising airflow to a certain height of the upper portion of the pulverizer, and the thickness of the crude particles falls under the action of gravity, and falls back to the lower portion of the mill in the mill, and the fine powder is moved to the upper turbine classifier. In the forced flow field generated by the high speed turbine, the crude particles are throwing near the wall under centrifugal force, and falling into the lower portion of the mill with the stall coarse powder, and the requirements of the fine powder are gradedThe film flow path is delivered to the cyclone via exhaust pipe as a product collection, and a small amount of fine powder is further separated by the bag trap, and the purification air is exhausted by the ventilator. The pulverized ventricular position is automatically controlled by the grading wheel dynamic current inverter, so that the pulverization is always optimal.
The airflow pulverizer produced by Yeli, Shandong is different from the same type of airflow pulverizer. It is designed with a special air seal structure at the moving gap between the turboxers and exhaust pipes. The thick particles do not The gap is mixed into the fine powder, thereby ensuring that the product particle size is controlled entirely by the rotation speed of the turbine, and the rotation speed of the turbine is controlled by the inverter, so the particle size of the product can be arbitrarily adjusted within the maximum amount, ensuring ultra-fine division precision and accurate Sex. At the same time, a special air seal isolation device is designed on the turbine grading machine transmission, which is extremely reliably preventing the fine powder from entering the bearing, thereby ensuring the normal operation of the high-speed bearing.
Since the reform and opening up, China has adhered to the basic national policy of opening up to the outside world. Open the national door to engage in construction, and gradually form an external open pattern in the whole multi-level wide area. The relevant leaders of the state have also said: "Comprehensive development of the world's development trend, economic globalization is the trend of the era of irreversible." Shandong Alpa Powder Technology Co., Ltd. As a professional powder equipment manufacturing enterprise, the Dongfeng of the policy is formed. Sales network throughout the world, with a number of overseas companies, products are exported to Australia, South Africa, Indonesia, Arab, Thailand and other regions.
