Spiral Jet Mill for Pine Wood Pellets As a smashing main device, the role is also growing, in the industrial sector of metallurgy, mine, chemical, cement, has a large number of raw materials and reuse waste every year. It is necessary to use a classifier to process processing. In the coking plant, sintering plants, ceramics factories, glass industries, powder metallurgy, etc., need to break the raw materials to the particle size required for the next job. In the chemical, power sector, the hierarchy, the raw material is broken, grind, increase the surface area of \u200b\u200bthe material, has created favorable conditions to shorten the chemical reaction of the material.
Spiral Jet Mill for Pine Wood Pellets is mainly used for more refined materials. The graded particle diameter is 1.5 to 0.005 mm, and the crude material is sieved. The principle of pulverization is substantially the same as the hydraulic level, and the above settlement theory can also be used for airflow classification. However, in the airflow classification, since the density and viscosity of the air are much smaller than the density and viscosity of water, the same particles are more settle more in the air than in the water. Moreover, the density and viscosity of the air varies with temperature and pressure.
In order to cause air flow, wind grading equipment typically requires an appropriate fan (exhaust or blast).
When the airflow is classified, the fine particles are typically taken away by the airflow. In some cases, the feedstock is sent together with the airflow into a grading device. It is well known that the load of solid particles in the air under normal pressure does not exceed 500 g / m3 air. When it reaches 1 kg / m3, the particles fall from the airflow. The load is related to the density and particle size of the particles. When the fine particle material is treated, the load generally does not exceed 200 to 300 g / 3 air. According to this calculation, the volume concentration of the solid in the gas stream is much smaller than 0.03. Therefore, when the airflow is classified, in most cases, it belongs to the free settlement.
The speed required to move the particulate material in the horizontal and vertical directions is relatively large, and the speed required in the horizontal direction is relatively large, and as the particle density increases, for example, for the density 1.5 of the pulverization coal per centimeter. The minimum wind speed is 2 m / sec; a powder material having a density of 2.5 g / cm, the speed is not less than 3.5 m / sec; a powder having a density of 4 g / cm 3, a minimum speed of 4 meters per second. Due to the complexity of the situation, the appropriate airflow rate in each particular situation should be determined by experiments.
In the rising airflow, the gas flow rate required to suspend the particles having a certain density and particle size is greater than the calculated value of the free settling, which is due to the uneven distribution of the airflow along the hierarchical chamber portion.
The spiral Jet Mill for Pine Wood Pellets has special grading range, high grading efficiency, high level precision, accurate cut particle size, and good stability.point.
In the conventional dispersion pulverization process, it is difficult to overcome the phenomenon of heating, viscosity. The machine uses a swirling high-speed rotational movement to produce a strong airflow in the mill. The material enters the crushing room under the negative pressure of the feed port. The vortex vibration generated by the strong gas flow between the blade and the module is generated by impact, shearing and grinding. The heat of the crushing room is taken away by the airflow, and the heat generated during the crushing process does not accumulate. The finished powder from the screen stream, improves the weight of the mill can be adjusted by the screen production efficiency, and the fineness is uniform.
Spiral Jet Mill for Pine Wood Pellets is important, you need to pay attention to the following:
1, check all the lines, electrical components, etc. of the pulverizer, whether it can work properly. Whether the machine is grounded, so that the housing is powered by electric shock. Whether the machine spindle has a card death, if it should be handled in time. Whether the machine has an abnormal situation during operation, if there is a stop check. 2, check the blade, is tightened, whether the blade gap can reach the specified standard. Before using the pulverizer, check the working room is enough or slidable, if it should be removed in time.
3, after the offset is running, it can begin to start the feed. The pulverizer should stop the feed before stopping. Wait until the machine is completely discharged, it can be stopped.
4, the feed should be uniform, not over, so as not to increase the burden on the machine. The pulverizer cannot be cleaned, maintenance, etc. during operation.
