pin mill for Modified starch

pin mill for modified starch As a striped main equipment, the role is also growing, in the industrial sector of metallurgy, mine, chemical, cement, requires a large number of raw materials and reuse waste every year. Processing is performed with a classifier. In the coking plant, sintering plants, ceramics factories, glass industries, powder metallurgy, etc., need to break the raw materials to the particle size of the next job requirements. In the chemical, power sector, the hierarchy, the raw material is broken, grind, and increases the surface area of ​​the material, has created favorable conditions to shorten the chemical reaction of the material.

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 settled in the air than in the water. Moreover, the density and viscosity of the air vary with temperature and pressure.

In order to cause air flow, wind pulverization equipment typically requires an appropriate fan (exhaust or blast).

When the airflow is classified, the fine product is usually taken away by the airflow. In some cases, the raw material is sent to a pulverized device from the airflow.

As is well known, 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 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 direction 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 pulverized coal and Western / cubic centimeter. The minimum wind speed is 2 m / sec; the powder material having a density of 2.5 g / cm, the speed is not less than 3.5 m / sec; the powder is 4 g / cm 3 powder, the minimum speed is 4 meters./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 water flow rate required to suspend a certain density and particle size is greater than the calculated value of free settling, which is due to the uneven distribution of the airflow along the pulverizing chamber portion.

The PIN MILL FOR MIDIFIED STARCH has a wide comminuted range, high pulverization efficiency, high pulverization accuracy, accurate cutting particle size, and good stability.
