Linear vibrating screen screen sequence classification
-
Linear vibrating screen has a certain order and attention to details in the process of installation and replacement of screen, incorrect installation method can not only be installed, but also damage the screen. Today we will tell you how to install the screen correctly. Linear vibrating screen is a kind of vibrating screen, relying on vibration motor as a vibration source, so that the screening material on the screen is thrown up at the same time forward linear motion. Common linear screen including DZSF series linear vibrating screen, ZSG series high efficiency heavy screen, ZSK mining linear screen. Linear screen screening process generally speaking is the material through the feeding mouth evenly into the linear screen, through the different levels of screen screening a variety of specifications of the screen, screen, and from different discharge mouth discharge, to achieve the purpose of screening. Linear vibrating screen with high output, low energy consumption, simple structure, easy maintenance, fully closed structure, no dust overflow, automatic discharge and other characteristics, more suitable for assembly line operation.
When the granularity level of the screening products of broken and scattered materials is more than two kinds, the problem of the screening order appears. The vibrating screening order has the following three kinds:
1. Overlap method
Sieve from coarse to fine. In the coarse to fine screen shunt process, the screen surface overlaps one by one, the upper screen surface mesh is larger, the following layers of screen surface mesh gradually reduced.
(1), the screen surface wear is small, although all the material and the largest chunk of the screen is added to the screen surface, but the screen surface is often composed of steel rod is not easy to wear, and to protect the following fine hole screen surface;
(2), fine level of material screening efficiency is higher, because the amount of material added to the fine hole screen surface is less;
(3), coarse level of material in the process of screen surface crushing phenomenon is less, because coarse level of material can be quickly separated from the screening process, which is of great significance to the screening of coal mines;
(4) because the screen surface is multi-layer overlapping, the arrangement of the screening device is relatively compact.
2. Sequence method
Sift from fine to coarse. In the screen shunt from fine to coarse, the screen faces are arranged in the order of increasing sieve holes.
Easy maintenance, easy to observe the working condition of each layer of screen surface, in addition, the screen can be discharged along the length of the screen surface.
3, combined method (mixed screening)
In the combined process, one part of the screen surface is arranged from coarse to fine, and the other part is arranged from fine to coarse. In manufacturing practice, coarse - to - fine or combined screens are usually used.
