There are many kinds of chemical fertilizers, the materials have different characteristics, the particles are large and small, the powder is thick and thin, sticky, non-sticky, etc., so there are many kinds of vibrating screen machines for screening fertilizers. For example, the large-grain urea sieve is not only a plane rotary screen, but also a rotary grading sieve, a swing sieve, a fertilizer grading sieve, etc., and the sieve sieving machine of the general sieve differentiation fertilizer is most commonly used with a plane rotary screen, a drum screen, an in-line vibrating screen, etc. For another example: most of the fertilizer in the field is screened by a flat screen, and the screen is screened and classified, but a large part is granular. In the case of powdered fertilizers, for example, the fertilizer used in vegetable greenhouses is screened and classified by a straight sieve, and the most commonly used compound fertilizer is a drum screen, which is also useful for a flat rotary screen. In fact, sometimes the material selection can have a variety of choices, the same material, but the precision requirements of the screening materials are not the same, or the processing volume is not the same, etc., you can use different sieve sorting.
Plane rotary screen, swing screen is mainly used for the screening and grading of chemical large grain urea, feed mill powder material or pellet feed, and also can be used for the primary clearing of raw materials in feed mills and the classification of intermediate products after secondary crushing of large and medium-sized feed mills. . In addition, it can be widely used in the screening and grading of raw materials and finished products in various industries such as food, food, chemical, sugar, mining, and paper.
The applicable occasions of the drum screen are as follows: 1. The stone yard is used for grading of large and small stones, and the soil and stone powder can be separated. 2. The sand field is used for sand and stone separation. 3. The coal industry is used for separation of lump coal and coal powder and coal washing. (Composition of coal washing machinery) 4. Chemical industry dressing industry for the classification of large and small blocks and separation of powdery materials, direct sieving, mostly used for flour, starch, washing powder, metal powder, additives, chemical, non-mineral and other industries The coarse screening of the powder, fine screening, large processing capacity, easy to combine with the production line, the choice range is between 600mm and 1800mm. Therefore, when you choose the sieve machine, you must choose according to the characteristics of your own fertilizer and your own requirements. A suitable vibratory screening machine.

Purgative Extract
Purgative extract refers to a type of substance or medication that is used to stimulate bowel movements or relieve constipation. These substances are often derived from certain plants or herbs and are used in traditional medicine. They work by irritating the lining of the bowel, causing a laxative effect. Examples of purgative extracts include senna, cascara, and aloe.
