What organic fertilizer raw materials are suitable for organic fertilizer disc mixers?
They are primarily suitable for processing organic fertilizer raw materials after fermentation or in the pre-processing stage, such as composted livestock and poultry manure, straw powder, mushroom residue, humus, and peat. They are particularly suitable for powdered or granular materials with a moisture content of 10%-20% and no large lumps. Micronutrients and microbial agents can be added to the materials.
Will composted wet materials stick to the mixer? How can this be avoided?
If the moisture content of the material exceeds 20% (slightly sticky), slight sticking may occur. This can be alleviated by: ① Select a model with a wear-resistant rubber scraper, which should adhere closely to the inner surface of the disc to promptly remove sticking materials; ② Reduce the single feed volume to avoid material accumulation; ③ Apply an anti-stick coating to the inner surface of the disc if necessary.
Is the equipment prone to wear? What is the lifespan of core components (such as the scraper and disc)?
When the material contains a high level of sand or coarse fiber, the scraper and disc bottom are prone to wear. The scraper is made of 65Mn wear-resistant steel or rubber and has a lifespan of approximately 3-6 months. The inner wall of the disc can be fitted with a wear-resistant lining, extending its lifespan to 1-2 years. Wear can be replaced individually, reducing maintenance costs.
Will the mixing process destroy the beneficial bacteria in the organic fertilizer?
The disc mixer uses physical mixing, without high temperatures or strong shear forces, and will not damage the activity of the inoculant. However, it is important to note that when mixing materials containing inoculants, avoid operating in high temperatures (>40°C) and limit the mixing time to 5-10 minutes. (Excessive mixing may cause slight temperature increases due to frictional heat.)
