Today, I talk about the stability of the RTM Turbo Mill device to ensure the quality of the quality. It is well known that RTM Turbo Mill has been widely valued by the industry.
Air supply. This is the driving force of the Jet Mill crushing process.
The requirements of compressed air can be between 0. 7 and 0.8 mA, maintain a stable pressure. Even if there is volatility, the frequency should not be too high, otherwise it will affect product quality. Secondly, the quality of the gas should be cleaned, and the compressed air should be cleaned and treated, remove water, oil mist and dust in the gas, so that the broken mineral material is not contaminated, and the crushing requirements for high purity materials are also high. higher. Raw materials supply. The raw material was placed in a raw material using a lifter and then sent the feedstock to the Jet Mill of the pulverity. This machine has strong adaptability to the particle size, usually from 325 raw materials. However, in actual production, the raw material processing has also achieved good results from 80 to 325. The speed of the raw material conveyor is automatically controlled, and the mixture of the raw materials and air in the pulverizing chamber remains relatively stable. This method can be used for optimal production of ultrafine powder during pulverization. Crush classification. Two pairs of nozzles are symmetrically mounted in the pulverizing chamber.
When the nozzle is formed by the nozzle, the compressed air is accelerated by the supersonic airflow band. The material collides with each other and pulverizes the ultrafine powder. The effect of pulverization is related to the shape, distance, symmetry, and the mixing of the nozzle inner diameter. The inner diameter of the nozzle determines the optimum speed and distance to form a sound speed, and determines the speed of the raw material. Whether it is ideal. The mixture of raw materials and air also affects the particle size and yield. Classification is carried out by a high speed rotation classification wheel. At the bottom of a circular "iron drum", the center of a hierarchy wheel is fixed on the spindle of the direct motor. It is driven by motor high-speed, and its opening is opposite to the fine powder collection system, and the gap cannot be too large. In addition, the coarse powder selected by the gap into the tube of the fine powder collection system, affecting the product quality. In order to prevent such an accident, gas sealing treatment is performed at the gap. The edge of the grading wheel is mounted, and the gap between the blades is a passage for separating fine powder. The powder after pulverization has risen with the gas flow, and the superfine powder passes through the gap between the blades into the dust collector.
The larger particles are splash to the outer wall under the centrifugal force of the graded wheel, and then shred again. By adjusting the speed of the hierarchy, you can get different sizes.Control of the concentration of the raw material and air mixture can be controlled by a capacitance material density control switch or sensor. This machine uses the current dimensional control of the hierarchy wheel drive motor. This control method is simple and feasible, easy to control. When the mixing density of the material and air increases, as the air flow increases, the dust density increases, the dust of the impact grading wheel increases, the current of the drive motor increases, the current of the drive motor is reduced, and the amount of the feedstock can be Co. Control, the mixed concentration of the material and air can be adjusted to optimal. Increase the drive current, stop the feed, maintain the dynamic balance between the powder and the delivery material to ensure the stability of product quality. The fine powder collection system consists of a cyclone separator and a dust collecting device. Ultrafine powder enters the cyclone separator, and the airflow rotates in the cyclone separator, and the ultrafine powder is throwded, and the package is a finished product. The cyclone separator can be used at level 1 or second. The airflow from the cyclone separator and some dust enter the dust collector, through the dust on the bag, discharge the exhaust gas under the action of the fan, and the dust content is small. In order to prevent dust from being discharged into the atmosphere, we also added a dust collector, recycled dust, and the exhaust gas was finally discharged into the air. up in the air. After multiple detection by the environmental protection department, the dust emissions are far below the emissions stipulated by the national environmental protection department.
The entire production process is automatically controlled by the control cabinet. The control cabinet provides the entire production motor (excluding the gas source). It also controls the adjustment of parameters, automatic start and stop, automatic protection, fault alarm, and automatic shutdown. Ensure that the equipment's safe operation and product quality Welcome to choose Shandong AlPa Powder Technology Co., Ltd., company specializing in the production and development and service of RTM Turbo Mill product technology, the company provides customers with safe and reliable RTM Turbo Mill products and services , Solve the worries of our customers.
