In the process of industrial pigment production, the whole set of production equipment system is strict and the equipment is sophisticated and advanced, but the products produced are directly put into the packaging machine, which often directly affects the product quality due to the presence of industrial impurities in the products, and customers demand compensation when exporting. How to ensure the quality of the products?

Purchasing and selecting reasonable equipment is the fundamental condition to ensure the product, so the products need to be screened before packaging, but the pigments are generally nano-level fineness, sticky and light, and agglomerated into particles, sometimes with large dust, which wastes raw materials and pollutes the environment. General screening machines cannot solve the screening problem. Using a special airflow screen for pigments to remove impurities is a foolproof solution. After being used by Hangzhou Lily Clariant Pigments Co., Ltd., Tianjin Organic First Chemical, Jinchuan Group and other companies, the effect is very good. Customers say: "It's like adding another lung to the system to purify the foreign matter of the raw materials." The specific operation method is very simple. Adding a matching airflow screen to the air path of airflow drying, airflow grinding, airflow air selection, and air selection crushing can achieve the purpose of filtering and removing impurities. Of course, an airflow screen system can also be added separately.

Pigment screening problem

The fineness of powdered pigments is an important factor affecting their quality and market value. Therefore, screening is an important step in the pigment production process. However, due to the high viscosity and easy agglomeration of pigments, the phenomenon of pigment agglomeration and screen blocking is particularly serious during the screening process. At the same time, the use of traditional screening technology has always been a major problem in pigment production, such as dust flying on site, environmental pollution, and loss of raw materials.
