The investment estimation of the whole process of vibrating screen screening in Henan asphalt mixing plant is screening efficiency and productivity. The former is a quality standard and the latter is a quantitative indicator. There is a certain correlation among them, in addition to many other factors, the result of this factor decision screening. The elements that endanger the whole process of screening can be roughly divided into three categories. The following Henan asphalt mixing station vibrating screen manufacturer will give you a detailed introduction:

The investment estimation of the whole process of vibrating screen screening in Henan asphalt mixing plant is screening efficiency and productivity. The former is a quality standard and the latter is a quantitative indicator. There is a certain correlation among them, in addition to many other factors, the result of this factor decision screening. The elements that endanger the whole process of screening can be roughly divided into three categories. The following Henan asphalt mixing station vibrating screen manufacturer will give you a detailed introduction:

 

 

Chemical properties of 1. sieved raw materials

Including the composition of the particle size distribution of the raw material itself, environmental humidity, mud content and the appearance of the object.

When the raw material fine sand has a large water content, the productivity of the sieve is also large. When the ambient humidity of the raw material is very large, the screening efficiency is generally reduced. However, the larger the mesh size, the smaller the water hazard. Therefore, for wet raw materials with large moisture content, in order to improve the whole screening process, the method of increasing the mesh can generally be selected, or wet test screening can be selected. The raw material contains large amount of mud (when the mud content exceeds 8%), wet test screening should be selected, or ore washing in advance.

2. the characteristics of the screen surface and the hazards of the main parameters of the structure.

Vibrating screen is to make the object and screen surface for vertical fitness exercise, so the screening efficiency is high, the production volume is large. The key to the relative speed of the object and the screen surface is the bar screen, the plane view vibrating screen, the barrel screen, etc. of the parallel surface fitness exercise, and its screening efficiency and production are low.

For certain raw materials, the productivity and screening efficiency of the sieve are decided by the size of the sieve. The productivity lies in the total screen surface width, and the screen surface width productivity is high. The screening efficiency lies in the length of the screen surface, and the long screening efficiency is high. General aspect ratio is 2.

The larger the reasonable total area of the sieve (I. e. the proportion of the total area of the sieve hole to the total area of the sieve surface), the higher the total area productivity and screening efficiency of the enterprise.

The larger the mesh size, the greater the productivity of the enterprise screen surface, the higher the screening efficiency.

Hazards of 3. Manufacturing Standards

When the load of the sieve is large, the screening efficiency is low. At a very large level, the friendship rate of a sieve lies in the size of the sieve holes and the total screening efficiency; the larger the sieve holes, the lower the specified screening efficiency, the higher the productivity.

The uniformity of the feeder is of great practical significance to the whole process of screening.

The inclination angle of the sieve should be suitable, which is generally clear according to the experiment. Furthermore, the amplitude and vibration of the sieve are related to the structural physical properties of the sieve. Within a certain range, the vibration can improve the screening index value.
