How to choose the length and width of the vibrating screen?

When we choose a vibrating screen, we generally pay attention to its model size. If it is used in different industries, the selected model size is also different. For example, if it is used in the mining production industry, then the vibrating screen must be of the heavy-duty type. Relatively speaking, the size of the model is relatively large, and the parameters that determine the size of the vibrating screen to a certain extent are the length and width of the vibrating screen, so how to choose the length and width of the vibrating screen?

1. Selection of the length of the vibrating screen

The selection of the length of the vibrating screen should be appropriate, because the screening efficiency of the linear vibrating screen is directly related to the length of the linear vibrating screen. If the length is too long, the screened materials will not be able to quickly leave the screen surface and affect the linear vibration. Screening effect. If the length is too short, the residence time of the material on the screen surface is too short, and it cannot be sufficiently screened. It is also unreasonable to increase the screening efficiency by using a longer screen surface to increase the screening time, so the length of the screen surface must be selected appropriately.

2. Selection of the width of the vibrating screen

At present, the width of the vibrating screen is at most 3.6m, and the width of the screen surface of the light-duty linear vibrating screen cannot exceed 1.5m. If the screen surface is too wide, it is difficult to ensure the uniformity of the material on the screen surface. In order to ensure the ability of the linear vibrating screen screening equipment, the material on the screen surface of the linear vibrating screen needs to have a certain thickness. When the thickness of the material on the screen surface reaches a certain level, the amount of the screen surface passing through it mainly depends on the linear vibrating screen. width. Therefore, the larger the production capacity, the wider the screen surface needs to be, but the width of the linear vibrating screen also has a certain limit.

1. Length affects the screening efficiency

As mentioned above, the length of the screen surface of the vibrating screen directly affects the screening efficiency of the screen machine, because the length of the screen surface affects the residence time of the screened material on the screen surface. The sieving test shows that when the sieving time is slightly increased, there are many particles smaller than the sieve hole, which pass through the sieve hole and pass through the sieve, so the sieving efficiency increases rapidly. However, as the sieving time increases, the easy-to-screen particles on the screen surface become less and less, and most of the remaining particles are difficult-to-screen particles, that is, the particle size of the material is close to the size of the sieve hole. It takes a long time to sieve these difficult-to-screen particles, and the increase of sieving efficiency is getting slower and slower. Therefore, the length of the screen surface is only within a certain range, which plays a role in improving the screening efficiency. The length of the screen surface cannot be excessively lengthened, otherwise the structure of the screening machine will be cumbersome and the expected effect will not be achieved.

2. Width affects processing power

The width of the vibrating screen determines the processing capacity. The width of the vibrating screen is not only affected by the processing capacity of the screening machine, but also by the structural strength of the screening machine. The larger the width, the larger the size of the vibrating screen, the more and more difficult the problem needs to be solved in the structural strength of the screening machine, so the width of the screen surface cannot be increased arbitrarily.

Relationship between length and width of vibrating screen

The relationship between the length and width of the vibrating screen is a mutual restriction and mutual influence. The length and width of the screen surface of the mining vibrating screen should maintain a certain proportional relationship, usually 2.5:1-3:1. Generally speaking, after the thickness of the material is given, the width of the screen surface of the mining vibrating screen affects the productivity of the screening machine, but the length of the screen surface directly affects the sorting efficiency of the screening machine, so the selection of the two should also be combined. In order to choose the parameters suitable for your own production conditions, that is to say, the length and width of the screen surface of the vibrating screen can be determined according to the comprehensive indicators of productivity and screening efficiency required by the use site.

The above is an introduction to how to choose the length and width of the vibrating screen. In general, the width should be at most 3.6m, and the length should be appropriately selected. The length and width affect the screening efficiency and processing capacity of the vibrating screen respectively, and there is a relationship between the two that restricts and affects each other, so the selection should be based on the specific working conditions.
