What are the factors that affect the screening of fertilizer vibrating screen in the NPK fertilizer production? Let’s have a look.

One, the influence of the production conditions of the vibrating screen of compound fertilizer equipment
When the load of the screen is large in the NPK fertilizer manufacturing process, the screening efficiency is low. To a large extent, the flat rate of the circular vibrating sieve depends on the size of the sieve hole and the total screening efficiency; the larger the sieve hole, the lower the required screening efficiency, the higher the productivity. The uniformity of feed is of great significance to the screening process.

Two. The screen surface properties and the influence of structural parameters
The linear screen makes the particles and the screen surface move vertically, so the screening efficiency is high and the production capacity is large. The relative movement of particles and the screen surface is mainly parallel-moving bar screens, plane vibrating screens, drum screens, etc., and their screening efficiency and production capacity are low.
For a certain material, the productivity and screening efficiency of the sieve are determined by the size of the sieve hole. The productivity depends on the width of the screen surface, and the width of the screen surface is high in productivity. The screening efficiency depends on the length of the screen surface, and the long screen surface has a high screening efficiency. Generally, the aspect ratio is 2.
The larger the effective sieve area (that is, the ratio of the sieve area to the entire sieve surface area), the higher the productivity per unit area of ​​the sieve surface and the screening efficiency. The larger the mesh size, the higher the productivity per unit screen surface and the higher the screening efficiency.
