The fluidized bed air flow crusher is to reduce the air through the Rawar spraying peak into the supersonic airflow and shoot into the crushed area to make the materials become darling (the airflow expansion is a darning bed suspended and boiling and collide with each other), so every every) A particle has the same motion state.
Qi source. This is the driving force for the crushing process of the airflow crusher. The requirements for compressed air can be kept stable between 0.7-10.8MPa. Even if there is fluctuations, the frequency should not be too high, otherwise it will affect the quality of the product. Secondly, the quality of the gas is required to clean and dry, and the compressed air should be purified, remove the water, oil mist, and dust in the gas, so that the crushed mineral materials are not polluted. The crushing requirements are higher. Supply of raw materials. In order to use the enhancer to increase the raw material in the raw material warehouse, and then send the raw material to the crushing room of the airflow crusher by the infusion valve. The machine has a strong granularity to the material. Generally, we require 325 destination raw materials. However, in practice, we have made good results from 80 meters to 325 destination mineral materials for processing. The speed of the raw material conveyor transportation raw materials is relatively stable with the concentration of automatic control to maintain the concentration of raw materials and air mixing of the crushed chamber. We use this method to achieve the super fine powder output ZUI when crushing. Smash and classify. There are two pairs of nozzles in the interior of the crushed indoor. When compressed the air, the supersonic air currents are formed when the nozzle is used to accelerate the raw materials, colliding with each other in the space, crushing the raw materials into ultra -fine powder, the crushing effect and the shape, distance, symmetry and raw materials of the nozzle, the symmetry, and raw materials It is related to the mixed concentration of air. The inner diameter shape of the nozzle determines the speed and distance of ZUI with the speed of the sound speed, and determines the acceleration of the raw material. Whether the speed is ideal. The mixed concentration of raw materials and air also affects product particle size and output. The classification of the air flow crusher is performed by a high -speed rotation. The hierarchical wheel is like a circle \u0026 ldquo; iron barrel \u0026 rdquo; the center of the bottom is fixed on the main axis of the direct -connected motor. The unprooped coarse powder enters the pipeline of the microfinage collection system from the gap, which affects the quality of the product. In order to prevent such incidents, gas sealing is performed at the gap. The leaf is installed with the side wheel, and the gap between the leaves is the channel for the sorting microfim. The crushed micro powder floats with the air flow. Due to the small particle size, the super fine powder is convenient for the gap between the leaves to enter the microfin dust collector. The larger particles are splashed behind the outer wall under the centrifugal force of the hierarchical wheel. Essence Adjust the speed of the hierarchical wheel, you can get products of different particle size. For the crushing chamber of the airflow crusher, the control of the mixed concentration of raw materials and air can control the switch or sensor control with a capacitive material density. This machine is controlled by the current of the hierarchical driver motor. This control method is simple, feasible, and easy to control. When the mixed concentration of materials and air increases, the density of dust floating in the air increases, and the pink of the hierarchical wheelIncreased dust, increased the current of the driving motor, and the current of the driving motor decreased. Using the size of the motor current to control the amount of transmitting raw materials, the mixed concentration of materials and air can be adjusted to ZUI. It is expected to achieve dynamic balance of powder and infusion to ensure the stability of product quality. The airflow crusher collection system consists of a whirlwind separator and dust collection. The ultra -fine powder enters the whirlwind separator through the sealing pipe. The airflow rotates in the whirlwind separator, throwing the ultra -fine powder out of the landing, and the packaging system is discharged by the excreted system. The whirlwind separator can use first or two. From the airflow of the whirlwind separator, there are also some dust entering the dust collector. Through the dust on the bag, the exhaust gas is pulled out under the influence of the campaign. The dust content is very small. We also added a set of dust filters to recover dust, and the exhaust ZUI was rowed into the atmosphere. After many testing by the environmental protection department, the amount of dust in its defense was greatly lower than the dust emission standards stipulated by the national environmental protection department. The entire production process is automatically controlled by the control cabinet. The control cabinet supplys the entire production motor (excluding gas source power). It can also control parameter adjustment, automatic start and stop, automatic protection, fault alarm and automatic stop. Guarantee the safe operation of the equipment and the stability of product quality.
