Vibratory Sifter for Pigment

Pigment introduction

Pigments are substances that can dye objects. Pigments are soluble and insoluble, and there are differences between inorganic and organic. Inorganic pigments are generally mineral substances. Humans have known for a long time that inorganic pigments are used to paint and paint on rock walls using colored soil and ores. Organic pigments are generally derived from plants and marine animals, such as cypress blue, garcinia, and ancient Roman purple extracted from shellfish.

Screening purpose

Adding a matching ultrasonic device to the ordinary vibratory sifter can achieve the purpose of filtering and removing impurities.

Pigment sieving problem

The precision and fineness of powder pigments are important factors that affect their quality and market value. Therefore, in the pigment production process, the screening process is an important link. However, due to the characteristics of high viscosity and easy clumping of the pigment, the phenomenon of pigment clumping and blocking the network during the screening process is particularly serious. At the same time, the traditional screening process is used to fly dust on site. , Environmental pollution, loss of raw materials and other issues have always been a major problem in pigment production.

Introduction of vibratory sifter for pigments

While the ultrasonic vibratory sifter screen is subjected to low-frequency vibration of the vibration motor, ultrasonic high-frequency vibration is superimposed on the surface of the screen, so that the large particles on the screen are suspended on the surface of the screen, and the mesh of the screen is prevented from being blocked. The above solves the technical problems of static electricity, easy agglomeration, strong adsorption, and blocking of the screen mesh that cannot be handled by ordinary vibrating screens. The processing capacity and output of materials that are usually difficult to screen and ultra-fine materials have been significantly improved.

Features of vibratory sifter for pigments

1. The screen has the function of anti-clogging and self-cleaning, which can screen up to 600 meshes, and there is no mesh blockage.

2. In a true sense, the screening phenomenon caused by difficult problems such as static electricity/easy agglomeration/strong adsorption is solved, and it can completely achieve the effective screening of ultra-high mesh.

3. The accuracy of the screening treatment can be increased by 1 to 70% in large steps, and the output can be increased to 1 to 10 times, with excellent performance.

4. The ultrasonic generator can choose two working modes, intermittent or continuous, the voltage adopts integrated circuit board, fully enclosed design, and digital CPU precise control.

5. The power of the power supply can be automatically adjusted between 18K-40K, and the low frequency can be converted to high frequency according to the specific gravity of the material. The transducer can work continuously for 12-24 hours.

6. The equipment does not need to be cooled down, and the connection between the vibrating screen and the ultrasonic power supply adopts advanced aviation fully enclosed joints.

7. It can ensure that the properties of the materials screened and processed will not change.
