Ultrasonic Vibrating Sieve for Pigment Powder

Pigment powder is also one of the main application industries of vibrating sieve. For the selection of vibrating sieve for sieving pigment powder, Dahan Machinery recommends to use ultrasonic vibrating sieve for the process of sieving and grading. The experimental data show that for common pigment powders with mesh numbers in the range of 100-150 mesh, the screening output of ordinary vibrating sieve is 190kg/h, while the data measured by ultrasonic vibrating sieve is 900kg. /h. Judging from the experimental data and screening effect, ultrasonic vibrating screen is more suitable for screening pigment powder, which is mainly determined by the special physical properties of pigment powder. The details are as follows:

Sieving difficulties of pigment powders

The fineness and fineness of powder pigments are important factors affecting their quality and market value. Therefore, in the pigment production process, the screening process is a very important link. However, due to the characteristics of easy adhesion, small particle size, light weight, and easy suspension of pigment powder materials, it is very easy to form material clumping and blocking of mesh holes due to these factors during the screening process, which seriously affects the normal operation. Screening output, the output per hour of ordinary vibrating sieve is less than 200kg.

In order to improve the screening accuracy and screening efficiency of pigment powder, it is necessary to find a vibrating screening equipment that can quickly break the materials that have been clumped together and prevent the suspension of materials. At the same time, there must be a complete sealing device to prevent the problems of dust flying on the process site, environmental pollution, and loss of raw materials in the process of high-speed screening of pigment powders with too light specific gravity.

It is precisely because the pigment powder has various special shapes described above, so Dahan vibrating sieve manufacturers recommend using ultrasonic vibrating sieve to complete the industrial pigment screening process. The ultrasonic fine powder vibrating screen machine developed and produced by Jinhe Machinery uses an intelligent vibration ultrasonic exciter to convert 220V, 50Hz or 110V, 60Hz electrical energy into 18KHz high-frequency electrical energy, input the ultrasonic transducer, and turn it into 18KHz mechanical vibration , thus successfully changing a single frequency to bring incompatibility and unadjustability.

It is precisely because the ultrasonic vibrating sieve has high vibration frequency, low amplitude and adjustable exciting force that the ordinary vibrating sieve does not have, it can effectively improve the leveling of the low-density powder in the gravity settlement (light contact between the powder and the mesh port). ), slip effect, improve the retention or wedging of high-density metal at the mesh port, and improve the adhesion effect of electrostatic powder, thereby improving the screening efficiency and screening quality. Expressed in terms of sieving pass rate, in general, the pass rate is increased by 50%-400% compared with no ultrasonic vibrating sieve, especially suitable for users of high value-added fine separation such as pigment powder.

Features of ultrasonic vibrating sieve for pigment powder

1. While achieving high-precision and high-mesh sieving, it can control a narrow particle size range.

2. It can be used in single-layer and multi-layer, and a set of intelligent ultrasonic generator uses three transducers at the same time.

3. Complete self-cleaning function of screen mesh: more than 500 mesh screening, no mesh blockage, no screening efficiency attenuation.

4. Really solve the screening problems such as strong adsorption, easy agglomeration, high static electricity, high precision, high density and light specific gravity.

5. Ensure that the characteristics of the processed materials remain unchanged.
