Tongda Heavy Industry Organic Fertilizer Crusher Equipment Advantages

The decomposition of fermented materials in organic fertilizer equipment mainly occurs on the surface of the particles or near the surface of the particles. Since oxygen can diffuse into the water film that wraps the particles, there is enough oxygen in these places to ensure the needs of aerobic metabolism.
Small particles have a larger surface area than larger particles for the same volume or mass. Therefore, if the oxygen supply is sufficient, the small particle material generally degrades faster. Experiments have shown that the degradation rate can be increased by 2 times after the fermented material is pulverized
above. The general recommended particle size is 1.3 ~ 7.6mm, the lower limit of this range is suitable for aeration or continuous turning fermentation systems, and the upper limit is suitable for static stacking or other static ventilation fermentation systems.
The effect of particle size of organic fertilizer equipment on fermentation:
The particle size of the conditioning agent also plays a very important role in the structural adjustment of the wet matrix. If the particle size of the conditioning agent is too small, it will lead to difficulty in achieving the desired free air porosity, and may make it difficult to achieve the desired volume of the solid phase of the mixed matrix. For example, some fermentation systems use wood chips or straw powder with small particle size called powder, resulting in a saturated mud-like mixed substrate, which is prone to anaerobic reactions due to the lack of voids.
In order to standardize the use of conditioners, we usually stipulate that sawdust and straw should not be less than 65% of the total solid phase in some places, 95% of which can pass through a 12mm sieve, and less than 50% of those that pass through a 2.23mm sieve; some specify the particle diameter. 50% of the solid phase ~
70% and 95% can pass through the 12.5mm sieve, and the pass through 4.75mm should be less than 20%. At the same time, the restriction on particles with large particle size is to avoid the need to sieve the processed granular product too large. If fermented products are used in horticulture or applied to lawns, gardens
When used, the particle size is generally not larger than 10mm.
Since the particle size of the organic fertilizer equipment affects the fermentation of organic fertilizer, it is easy to cause anaerobic reaction and other conditions that are not conducive to the fermentation of organic fertilizer. Therefore, there is a requirement that the particle size of the material is not less than 1mm and not more than 10mm. The pretreatment and crushing process of the organic fertilizer pulverizer is to make the particle size of the material suitable for the requirement of not more than 10mm. Common organic fertilizer material pulverizers on the market include high-moisture material pulverizers, semi-wet material pulverizers, cage pulverizers, vertical pulverizers, double-shaft pulverizers, etc.
The crushing effects of several common types of organic fertilizer crushers are relatively good. We compare the particle sizes of several types of crushers after crushing:
High-moisture material pulverizer and semi-moist material pulverizer pulverized material particle size: the average particle size is 3-5mm; it is very suitable for processing organic fertilizer straw and sawdust.
The particle size of the crushed material: 0.1mm- -0.7mm, obviously the crushed particle size is too small, and it is mostly used for the particle size requirements of organic fertilizer and compound fertilizer post-processing fertilizer particles.
The particle size of the material after being crushed by the vertical crusher is 3-5mm, which is also more suitable for the pretreatment and crushing process of organic fertilizer raw materials.
Tongda Heavy Work is an organic fertilizer equipment manufacturer, and the processed organic fertilizer pulverizer equipment has the following advantages:
