Since the 1980s, with the development of the national economy, more and more industries need to dry ultra-fine powder on materials, PIN Grinder of ammonium phosphate is the most effective equipment for achieving ultrafine powder mills. one. In my country, after 20 years of development, the Pin Grinder of Ammonium Phosphate industry has been widely used in pesticides, food, medicine, fine chemical, electronic battery materials and other fields.
PIN Grinder of ammonium phosphate is mainly used for more refined materials. The pulverized 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 pulverization 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 raw material is sent to the gas stream into a pulverized device.
It is well known that the load of solid particles in 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 airflow speed 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 grinder of ammonium phosphate has the characteristics of high pulverization, high pulverization efficiency, high pulverization precision, and good cutting particle size and good stability.

The quality of different manufacturers, the quality of the equipment will be different, determine PIN Grinder of ammonium phosphate different prices. When we purchase goods, we will pay attention to quality and prices, but when buying equipment, it is not easy to find high cost-effective factories. There are two reasons for causing price differences. Some manufacturers blindly cut prices, but in terms of material consumption, they will choose inferior materials to save costs and fees, which will not only harm the customer's interests, but will have a negative impact on the entire industry. Another situation is that some large manufacturers have raised the price of equipment, equipment and general quality, resulting in high equipment prices to give the equipment. Through the above analysis, customers are required to conduct field inspections when purchasing a crusher, from equipment quality, plant scale and after-sales service, etc., to find the right equipment.
