What type of lab sieve sheker is appropriate?
In the process of scientific research institutions, universities, the analysis and determination of the composition of raw materials is the important data that influences the accuracy of scientific research data.Therefore, it is very important to choose which laboratory vibrating screen to screen raw materials in laboratory research equipment.Our technical personnel will explain the various situations that may appear, and help users choose the right type according to the actual usage.
Generally speaking, it is divided into two aspects, one is the selection of vibrating screen type, and the other is the type selection of the sieve.From the screen machine, analysis of particle size of the raw materials used in the laboratory have a variety of specifications, such as the most common standard models, swing, ultrasonic, etc., with their own advantages and disadvantages.We explain the main ones of these.Here we first from the user's raw materials to explain,the standard model of Lab sieve is one of the most widely used shakers. the main factor is its screen size, cost and operability.However, in response to 300 mesh of fine material powder, there will be problems,such as network, static electricity, adsorption and so on.These problems affect the accuracy of analyzing data.Therefore, in the selection of raw material powder in this kind of scope, the usually selected vibrating screen will have a certain cleaning device or have the effect of self-cleaning network to obtain the most accurate analysis data.
Ultrasonic lab sieve is a self-cleaning function of the laboratory vibrating screen,not only cost-effective, but also according to the user's different size of the raw material with different types of sieve, the wave can be passed on the screen can play a self-cleaning effect.In the easy to produce static electricity, with a certain viscosity of the raw material has a better sieve effect, better to ensure the accuracy of screening data.In contrast to the standard comparison, this type of vibrating screen can only place 8 sieves at the same time, and the raw materials of 9 different particle sizes can be obtained.
Laboratory selection of vibrating screen points lies mainly in the following two aspects: 1, the material characteristics, viscosity, moisture content, particle size, etc., according to these features to choose appropriate experimental sieve and clear way. 2. The size of the sieve shall be selected (size of sieve hole).
