With the continuous development of river pebble resources, river pebble mine sieve plays an increasingly important role in the process of river pebble processing, as an important screening equipment. This article will introduce in detail the structure, working principle, classification and common problems and solutions in the process of use of river pebble mine screen.
First, the structure of the sieve for river pebble mine.
The river pebble mine screen is usually composed of a screen box, a screen, a vibrator, a shock absorber and a motor. The screen box is the main structure of the whole sieve, which is usually made of high-quality steel with good strength and durability. The screen is the core component of material screening, which is generally made of high-strength and wear-resistant steel wire, and can be selected with different mesh screens according to different screening needs. The function of the vibrator is to make the screen vibrate, so that the material moves on the screen and completes the screening. The shock absorber is designed to reduce the impact of vibration on the entire screen and ensure the stability and accuracy of the screening. The motor is the power source of the whole sieve, and explosion-proof and low-noise motors are usually selected to ensure safety and environmental protection.
Second, the working principle of the sieve for river pebble mine.
The working principle of the river pebble mine screen is mainly to use a vibrator and a motor to drive the screen to produce a certain frequency of vibration, so that the material moves on the screen and completes the screening. In the screening process, screens with different mesh numbers can separate materials with different particle sizes, so as to achieve the classification of materials. At the same time, the presence of shock absorbers can reduce the impact of vibration on the whole sieve and ensure the stability and accuracy of screening.
3. Classification of sieves for river pebble mines.
According to different classification criteria, river pebble mine sieves can be divided into many types. According to the screening method, it can be divided into linear vibrating screen and circular vibrating screen; According to the screening object, it can be divided into wet screening and dry screening; According to the structural characteristics, it can be divided into hanging screen and seat screen. Different types of river pebble mine screens have different characteristics and scope of use, and users can choose the screening equipment that suits them according to their actual needs.
Fourth, the common problems and solutions in the use of river pebble mine screens.
In the process of using river pebble mine screens, there may be some common problems, such as screen blockage, material stuckness, excessive noise, etc. In response to these problems, corresponding solutions can be taken. For the problem of screen blockage, the screen can be checked and cleaned regularly to avoid the influence of debris and accumulated materials on the screening effect; For the problem of material stuckness, the feeding method and flow rate can be adjusted to ensure the smooth flow of materials; For the problem of excessive noise, low-noise motors and shock absorbers can be selected to reduce the impact of vibration and noise on the surrounding environment.
