How to select a compost turner machine?

During the process of commercial organic fertilizer production, there is a crucial equipment that plays a significant role in organic wastes fermentation stage—compost turner machine, we would introduce some basic knowledge about compost turner, including its functions, types and how to choose a suitable one.


Function of compost turner

Compost turner has become the core equipment of dynamic aerobic composting in virtue of the important effects on compost and fermentation.

♦ Mixing function in tempering of raw materials: in composting, it is necessary to add some minor ingredient in order to adjust the carbon nitrogen ratio, pH value and water content of raw materials. Main raw materials and minor ingredients that are put together according to certain proportion could be mixed uniformly by professional compost turner for better tempering.

♦ Adjust the temperature of raw materials piles: during the working process, compost turner can make raw materials fully contact and mix with air, which can adjust the temperature of piles conveniently. Air helps aerobic microorganisms to produce fermentation heat actively, pile temperature rising. Meanwhile, if piles temperature is high, turning piles can bring the supply of fresh air, which can lower the temperature. And various beneficial microorganisms grow and breed in the adaptive temperature range.

♦ Improving the permeability of ingredient piles: composting system can also crush the stick and ropy raw materials into small mass, making piles fluffy, stretchy and with appropriate porosity, which has been an important standard to measure the performance of compost turner.

♦ Adjusting the moisture of raw materials piles: The water content of raw materials for fermentation should be controlled within 55%. In fermentation, the biochemical reaction will generate new moisture, and the consumption of microorganisms to raw materials will make the moisture lose the carrier and free out. Therefore, with the timely reduction of moisture in the fermentation process, in addition to evaporation formed by heat conduction, the turning of raw materials pile by the compost turner machine will also form a mandatory evaporation of water vapor.

♦ Realizing the special requirement of composting process: for instance, compost turner could realize the requirements of crushing raw materials and continuous turning.

The composting machine makes fermentation simpler, shorter cycles and achieves the expected fermentation effect. The following are several common compost turner machines.


Types of compost turner

Chain plate Compost Turner

This series of compost turner are very well-designed, the chain using high quality and durable parts. Hydraulic system is used for lifting and lowering, and the turnover depth can reach 1.8-3 meters. Material vertical lifting height can reach 2 meters. It

can do the turning job faster, more effectively and with added utility. With the characteristics of compact design, simple operation and saving workplace, this composting machine could be conveniently used in various fields of different raw materials, such as livestock manure, domestic sludge, food waste, agricultural organic waste and so on.

Groove Type Compost Turner

It adopts the chain drive and rolling support plate structure with small turning resistance, energy saving and suitable for deep groove composting operation. Besides, it has crushing ability and the materials pile has a good effect of oxygen filling. Its horizontal and vertical movement can realize the turning operation at any position in the groove, which is flexible. But it also has limitation that it can only work with fermentation tank, so choosing this one need to build the matched fermentation tank.

Crawler type Compost Turner

This crawler type compost turner is specially designed equipment for windrow composting and fermentation technology to produce organic fertilizer. It not only suit for outdoor open area, but also for workshop and greenhouse. It has strong adaptability, safe and reliable performance, and convenient maintenance. According to the principle of aerobic fermentation, this machine provides enough space for zymogeneous bacteria to play its role.

Wheel type Compost Turner

Wheel Type Composting Turner Machine is an automatic composting and fermentation equipment with long span and depths of livestock manure, sludge and garbage, filtration mud, inferior slag cakes and straw sawdust in sugar mills, and is also widely used in fermentation and dehydration in organic fertilizer plants, compound fertilizer plants, sludge and garbage factories, garden farms and bismuth plants.

Tips for choosing a compost turner

Whether you’re just entering the market, or are experienced with composting, questions always arise as to what type of compost turner would be best fit your needs and bottom line. The choices would narrow substantially after considering the factors, conditions and objectives of the composting operation.

When purchasing, ensure the equipment is safe and reliable.

The throughput of a particular compost turner is determined by its working travel speed and the size of the windrow that it can handle.

● Choose the compost turner according to the actual materials piles and turning throughput. Larger and more powerful machines generally have greater throughput rates because they process larger raw materials piles.
● Also consider the space need of the compost turner machine. The crawler type compost turner will need less aisle space then other models.
● Cost and budget, of course, also affect the choice of composting equipment. The machine with larger throughput and capacity would have higher prices, so choose the suitable one.
