A defoamer or an anti-foaming agent is a chemical additive that reduces and hinders the formation of foam in industrial process liquids. The terms anti-foam agent and defoamer are often used interchangeably. Strictly speaking, defoamers eliminate existing foam and anti-foamers prevent the formation of further foam. Commonly used agents are insoluble oils, polydimethylsiloxanes and other silicones, certain alcohols, stearates and glycols. The additive is used to prevent formation of foam or is added to break a foam already formed.

Where q 0 - the amount of processing per unit area of ​​the curved screen, m 3 / (m 2 · h);
Selection and application of curved screen
It is generally used for wet grading, dewatering, and dematerialization of heavy medium dressing . The utility model has the advantages of simple structure, light weight, small occupation area, no moving parts, large processing capacity, high separation precision, and meshing holes are not easy to be blocked, but the product on the screen has high moisture, the screen strip wears fast, the ore requirement is uniform and a certain pressure is required. The relationship between the size of the curved sieve mesh and the calculated particle size of the undersize product is shown in the table below.

Calculation of the amount of curved screen processing
q=160φAυ (1)
Where q - the amount of curved sieve treatment, m 3 / h;
A - screen area, m 3 ;
Φ——the effective area coefficient of the screen, generally taking φ=0.3~0.4;
υ——The feed rate of the slurry, when the slurry is fed in, υ=0.3~3m/s; when the slurry is pumped in, the υ can reach 6m/s.
The curved screen can also be used to calculate the throughput per unit area.
D——mesh size, mm.
