What are the Sieve Techniques of Linear Vibrating Screen?

 

 

The linear vibrating screen utilizes a vibrating motor as the resource of vibration, to ensure that the material is thrown up on the screen while moving forward in a straight line. The material gets in the inlet of the screening machine evenly from the feeder, as well as creates data via the multi-layer screen. The oversieve as well as undersieve of various specs are released from their particular electrical outlets. It has low power consumption, high outcome, simple structure, simple maintenance, completely confined framework, no dust spillage, automated discharge, and is better for production line procedures. So do you know what are the sieving approaches of the linear vibrating screen? Let me describe it to you next. In the sieving process of materials, the powder example is gone through a series of standard filters with different filter holes, separated into several fragment grades, and also evaluated individually. The bit size distribution expressed as a mass percentage is called the screen analysis technique That is, screen analysis, the objective of which is to determine the particle size structure of the material. There are three common screening approaches; these three screening approaches can approximately meet the screening needs of users for different materials. The linear vibrating sieve analysis approach can be split into several kinds, such as dry sieving, wet sieving, hand sieving, dry and also wet mixing, mechanical sieving, air jet sieving, acoustic sieving, panning sieving and self-organizing sieving. And so forth, the outcomes of screen analysis commonly use frequency distribution as well as collective circulation to share the bit size distribution. There are numerous techniques pointed out above, it depends on which material the customer screens, so as to pick the suitable screening method, but the more generally used are the initial three, let's take a look together next.

 

1. Dry sieving technique

The so-called dry sieving approach, as the name indicates, is to determine the difference between the amount of the sieving balance and also the bottom stock of each sieving meter as well as the complete dry mass m0 of the example prior to sieving, as the loss during sieving, as well as determine the loss price. A particular weight of powder sample in the filter is used to make the fine powder pass through the filter with the help of mechanical vibration or hands-on tapping till the sieving is finished. The filter residue of the powder sample is determined according to the weight of the residue on the screen and also the weight of the sample. When establishing the particle size circulation, dry sieving is generally used.

 

2. Wet screen technique

Place a particular weight of powder sample in the sieve and clean it for a specific time period with a suitable diffusion water stream (with a specific water pressure), and afterwards the sieving is complete. According to the weight of the sieve deposit as well as the weight of the sample, the wet filter method is used to obtain the filter deposit of the powder example. If the sample consists of a lot more water and the particles have solid cohesiveness, wet sieving must be used (the accuracy is more than that of dry sieving), especially for materials with finer particles. If it is enabled to blend with water, it is best to make use of wet sieving. Due to the fact that the wet approach can protect against really great bits from sticking to the sieve holes as well as obstructing the sieve openings. In addition, the wet approach is not affected by the material temperature and atmospheric humidity, and also the wet technique can also improve the operating problems. Therefore, the wet approach and the thousand approach have been provided as the nationwide standard approach for the resolution of the fineness of concrete and also resources.

 

3. Integrated screen evaluation of wet and also dry

Integrated dry-wet filter evaluation is to integrate the two methods and also select the best. When the material has a lot more water as well as mud, and also the materials are adhered to each other, the combined dry-wet filter evaluation method ought to be used, and the outcomes acquired by the sieve evaluation are a lot more accurate. The specific method is to pour the example right into a fine-hole sieve and screen it in a basin having water. Modification the water in the basin every 1 to 2 minutes till the water in the basin is no longer turbid. The material on the screen is dried out and also evaluated, as well as the top quality of the washed penalty mud is determined based on the difference between the evaluated mass and also the mass of the initial sample.

 

The three screening techniques pointed out above usage basic equipment and also very easy operation, yet the screening results are easily affected by the shape of the particles. The size of the particle size circulation is fairly rugged. When the lower limit of the examination exceeds a specific value, the screening time will certainly be decreased. Expanding, it is simple to block the screen. For that reason, when screening, the bit size of the material need to be changed as much as feasible to stay clear of the material from blocking the screen.
