How to choose vibrating screen accessories
The vibrating screen consists of a vibrating motor, a screen, a grid, a bearing, a bouncing ball, etc. Most of which are wearing parts, no matter which damage will affect the screening effect and efficiency of the equipment, these parts are replaced frequently, which requires The user of the vibrating screen selects the appropriate spare vibrating screen accessories. The advent of the vibrating screen greatly saves labor costs and production costs. How to choose the vibrating screen accessories so that the vibrating screen can truly achieve high quality and high efficiency production requirements?
1.Select vibrating screen accessories vibration source - vibration motor
The vibration motor is the core component of the vibratory screening machine, which is the vibration exciter. The magnitude of the exciting force is determined by the size of the vibrating screen, the characteristics of the material, and the amount of processing. The weight of the screening machine and the amount of processing are different, so the size of the vibration motor is also different. If the exciting force is too large, the vibrating screening machine will crack due to excessive excitation force. On the other hand, if the exciting force is too small, the treatment effect will not be achieved, and material accumulation and blocking may occur.
2.How to choose a screen
The screen is an indispensable accessory for the vibrating screen and is the part that is in direct contact with the material. Generally, the material of the vibrating screen is divided into: 316L, 316, and 304. Depending on the material to be screened, different screens should be selected. 316L (316) is used for acid and alkali resistance or for food and medicine screening. If there is no special requirement, the screening material can be selected from 304.
3.Select vibrating screen accessory support equipment--bearing
The bearing is also the support point of the vibration motor or the vibration exciter. It is one of the most critical components in the vibrating screen equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient and the rotation precision during the operation of the vibrating screening machine. Therefore, the following points should be noted when selecting bearings:
1. Check for cracks, impurities and rust inside and outside the bearing;
2. There is no noise when turning, and there is turbid oil stain on the surface;
3. Check the clearance of the bearing, whether the size is within the error range;
4.Select vibrating screen accessories cleaning device - bouncing ball
The bouncing ball acts to clean up the clogged material in the vibrating screen. Bouncing balls are divided into 10, 15, 20, 25, 28, 30, and 40 by size. According to the material: rubber: used for the screening of general materials; silica gel: better than rubber, good wear resistance, not easy to fall off. Usually suitable for screening of food, medicine and other materials.
