Comparison between trough compost turners and crawler compost turners

Written by fertilizer production line on . Leave a comment

In the composting equipment of organic fertilizer production lines, compost turning machine and windrow compost turning machine have their own advantages. Choosing suitable equipment can make production efficiency more efficient.

In terms of application scenarios,compost turning machines are suitable for fixed-site operations and need to be used in conjunction with fermentation tanks. The width of a single tank is usually 3-5 meters and the depth is 1-1.5 meters. They are suitable for large-scale and standardized production bases, especially in the continuous fermentation line of organic fertilizer plants. Windrow compost turning machines are experts in mobile operations. The crawler design enables them to shuttle freely in muddy sites without the need for preset fermentation tanks. The pile height can reach more than 1.5 meters.

Each has its own focus on operating efficiency. The compost turning machine relies on chain transmission to drive the turning and throwing teeth. The hourly processing capacity can reach 50-100 tons. The turning and throwing depth is uniform, the material is highly broken, and oxygen can be fully integrated. The fermentation cycle can be shortened to 7-10 days. Windrow compost turning machines rely on hydraulically driven rotating blades to process 30-80 tons per hour. Although the efficiency per hour is slightly lower, they can adapt to irregular piles and have a small turning radius. Their flexibility in operation on complex sites far exceeds that of trough compost turners.

There are obvious differences in operation and maintenance. Compost turning machines require regular adjustment of chain tension and monthly lubrication of sprocket bearings. Due to fixed operations, the replacement cycle of wear parts is relatively long. Windrow compost turning machines require weekly inspection of track tightness and grease of blade bearings every 100 hours, but their modular design makes replacement of wearing parts more convenient and less time-consuming for daily maintenance.

In terms of energy consumption and cost, compost turning machines have 15%-20% lower energy consumption per unit of processing capacity, but they need to invest in fermentation tank construction in the early stage. Windrow compost turning machines have low initial investment, and mobile operations save site renovation costs, making them suitable for small and medium-sized enterprises.

Both can meet the requirements of harmless compost treatment. The compost turning machine is suitable for large-scale and standardized production, while the windrow compost turning machine is suitable for flexible and changeable operation scenarios. Only by choosing according to your own production needs can you make compost treatment efficient and economical, and help the development of green industry.

Fermentation Mode of Chicken Manure Organic Fertilizer Manufacturing Process

Written by fertilizer production line on .

Organic fertilizer, commonly known as farm manure, consists of various animal, plant residues or metabolites, such as human and animal manure, straw, animal residues, slaughterhouse waste, etc. Carbon-containing materials, mainly from plants and animals, are applied to the soil to provide plant nutrition as its main function. It not only provides comprehensive nutrition for crops, but also has long fertilizer efficiency. It can increase and renew soil organic matter, promote microbial reproduction, improve soil physical and chemical properties and biological activity. It is the main nutrient in green food production.

The production of organic fertilizer must go through composting fermentation process. Composting is a process in which organic matter is continuously degraded and stabilized by microorganisms under certain conditions, and a product suitable for land use is produced.

Site selection

The site should be flat, near the water source and sunny from the leeward. It does not pollute the environment and is easy to provide water. 

Chicken Manure Organic Fertilizer Fermentation Mode

1. Store the materials and add the bacteria proportionally. Water content should be controlled at 60%-70%. Fermentation of less water is slow and aeration of more water is poor. Oxygen deficiency will corrupt and produce odor.

2. The start-up temperature is better than 15℃ (can be operated in four seasons, not affected by season, fermentation in indoor or greenhouse in winter as far as possible), and the fermentation temperature should be controlled between 60 ~65℃.

3. Fermentation of organic fertilizer needs oxygen consumption fermentation. In the process of operation, oxygen supply measures should be increased so as to mix well, turn over frequently and ventilate properly. The windrow turner can work accurately to meet the requirements, it’s an important equipment of fertilizer fermention. Windrow compost turning machine has the advantage of high efficiency, smooth operation, strong and durable, even turning throw.

4. Fermentation

Warming-up stage: generally only one day is needed from room temperature to 50℃.

High temperature stage: generally only 2 days from 50-70℃.

Cooling stage: from high temperature to below 50℃, generally about two weeks. The temperature began to drop to normal temperature, indicating that the fermentation was completed.

FAQ of Organic Fertilizer Fermentation:

1. Slow warming: no or slow warming of the reactor

Material is too wet, too dry, there is not enough nitrogen source, and the pH is too low.

2. Heap temperature is too high: during fermentation, the heap temperature is more than 65℃.

Poor permeability.

3. Odor: The odor of rotten eggs or rotten eggs is emitted from the stack.

Ammonia content is too high, material stacking is too dense.

After being processed by the chicken manure organic fertilizer production equipment, these organic fertilizers can be sold. Huaqiang fertilizer machine manufacturer supply professional organic fertilizer production line, and a series comprehensive service.
