The commercial organic fertilizer production process includes: organic material inoculation fermentation (pre-fermentation), main fermentation, crushing, compounding and mixing, drying, granulation, cooling, screening, metering packaging and other processes. The organic fertilizer production equipment mainly includes fermentation tanks, mixers, turning equipment, belt conveyors, drum screens, pulverizers, organic fertilizer granulator machine, etc. Crusher is an important equipment for raw material processing in the early stage.
Organic fertilizer equipment semi-wet material pulverizer is widely used in chemical fertilizer, mining, coal mine and other industries, and plays a very important role in the pulverization process of organic fertilizer raw materials. The target moisture content of this machine is 30%, and the pulverization of 60% wet material ,the effect is particularly remarkable, such as livestock manure, urban sludge, biogas residue, kelp residue, etc, its application effectively solves the problems of high water content and difficult crushing, and it is also a widely used organic fertilizer crushing equipment. How to improve the crushing capacity of fertilizer grinder?
1. Material selection is the core. Hardness needs to be paid attention to when selecting materials. The harder the material to crush, the more serious the damage to the equipment. Due to the damage to the equipment, the crushing speed slows down, and the crushing force is naturally smaller.
2. The humidity of the material is the key. When the moisture content of the material is high, the material is easy to adhere to the inside of the crusher, causing blockage during the material conveying process, thereby reducing the crushing capacity. Therefore, it is very necessary to reduce the moisture content of the material before crushing, so that the crusher can work better.
3. Composition of the material. Materials with more fine powder are not conducive to crushing. Because these fine powders are easy to stick and difficult to transport, materials with more fine powder should be screened in advance.
4. If the fineness of the crushed material is required to be high, that is, the finer the material, the smaller the crushing capacity.
5. The viscosity of the material. The greater the viscosity of the material, the easier it is to adhere.
6. The wear resistance of the crushing part of the crusher determines the crushing capacity.
