Large Wheel Compost Turner

Large Wheel Compost Turner

The large  wheel compost turner is an efficient turning equipment specially designed for large-scale aerobic fermentation processes. It is the core fermentation equipment in the fields of large-scale production of organic fertilizers, municipal sludge treatment and agricultural waste resource utilization. This equipment relies on the mechanical wheel mixing structure and cooperates with the aerobic fermentation process to complete the entire process of turning, stirring, oxygen supply, and shifting of materials to accelerate the decomposition and fermentation of organic materials. The large wheel turner is specially designed for large tank fermentation workshops and is suitable for high-output organic fertilizer production scenarios.

In organic fertilizer production, fermentation and compost turning is a key process that determines product quality and production efficiency. Large wheel compost turners have become the core equipment of 10,000-ton fermentation projects due to their outstanding advantages of ultra-large processing capacity, efficient turning capabilities, and stable operating performance. The equipment can not only realize the uniform turning of the pile, but also ensure the controllable fermentation cycle, helping enterprises to efficiently achieve large-scale production goals. Compared with traditional turning equipment, the large-scale wheel turner has a qualitative leap in turning depth, turning range, turning uniformity and degree of automation. It is a high-end supporting equipment for large-scale harmless treatment of septic waste and standardized mass production of organic fertilizers.

Overall structure and core components
The large-wheel compost turner, with its powerful turning capacity and processing capacity, can efficiently ferment a variety of large-scale organic raw materials, including the following:
Livestock and poultry manure
This includes large-scale manure such as chicken manure, pig manure, and cow manure produced by large-scale livestock farms. The large-wheel compost turner's powerful turning quickly breaks down compacted layers of manure, kills pathogens, parasite eggs, and weed seeds through high-temperature fermentation, and eliminates odor. Its processing capacity can reach hundreds of tons per day, meeting the manure treatment needs of large-scale livestock farms.
Crop straw
This includes straw from large-scale crop production, such as corn straw, wheat straw, and rice straw. The large-wheel compost turner shreds bundles of straw and evenly mixes it with manure and other materials, promoting the degradation of cellulose and hemicellulose in the straw, converting it into organic matter for organic fertilizer, thereby addressing the environmental pollution caused by straw incineration.
Industrial organic waste
This includes large-scale industrial organic waste such as distiller's grains from alcohol plants, sugar residue from sugar refineries, and medicinal residue from traditional Chinese medicine factories. These materials have a high moisture content and are prone to spoilage. Large-wheel compost turning machines, through continuous turning, can quickly reduce moisture content, promote the growth of beneficial microorganisms, and achieve large-scale resource utilization of industrial waste.
Municipal Sludge
Large quantities of sludge generated by municipal sewage treatment plants can be fermented using large-wheel compost turning machines after heavy metal content testing meets standards. The turning process reduces the sludge's moisture content (from approximately 80% to below 60%), stabilizes its properties, eliminates odors, and transforms it into a safe organic fertilizer.
Garden Waste
Landscape waste, such as fallen branches and leaves, and weeds, generated during urban landscaping, can be mixed with other organic materials and fermented in a large-wheel compost turning machine to produce humus-rich organic fertilizer, thus achieving the recycling of urban landscaping waste.

Operating principle and working mechanism

The large wheel compost turner relies on the mechanical  wheel compost mixing structure and cooperates with the aerobic fermentation process to complete the turning, mixing, oxygen supply, and displacement of materials, and accelerate the decomposition and fermentation of organic materials. Its work process can be divided into three core links:

Material mixing and crushing link: The equipment is equipped with a high-strength wear-resistant wheel disc and evenly distributed sets of three-dimensional rake teeth. During operation, the wheel rotates at high speed and penetrates deep into the bottom layer of materials in the fermentation tank to completely break up and break up the compacted livestock and poultry manure, straw auxiliary materials and other materials. This process effectively solves the problem of material hardening and agglomeration, loosens densely packed materials, and creates basic conditions for aerobic fermentation.

Aeration and oxygen supply fermentation link: This is the core working principle of the equipment. The decomposition of organic materials relies on the decomposition of aerobic microorganisms, and the key to microbial activity is sufficient oxygen. During the process of turning materials, the wheel turner drives the materials to continuously roll and throw through the rotation of the wheel, allowing the materials to fully contact the air over a large area and quickly replenishing the oxygen inside the fermentation pile. At the same time, the turning process can reduce the humidity and temperature of the pile, avoid the odor generated by anaerobic fermentation of materials, and greatly activate microbial activity.

Material shifting and cyclic fermentation: The  wheel compost turning machine has a directional shifting function during operation. Each turning will move the material forward a certain distance at a constant speed. As the equipment repeatedly operates back and forth, the material gradually moves from the feed end of the fermentation tank to the discharge end, completing continuous fermentation and ripening throughout the process. The entire process does not require manual transfer of materials, and realizes automated assembly line operations of feeding, turning, fermentation, and discharging, greatly improving production efficiency.

Core advantages and performance highlights
The large  wheel compost pile turner has the following outstanding advantages: high turning depth - the turning depth can reach 1.5-3 meters, and can cover deep piles. Large turning span - the maximum turning width can reach 30 meters, suitable for large-span fermentation workshops. Uniform tossing without dead ends - the  wheel compost plate is turned symmetrically, and with the cooperation of the speed-adjustable shift trolley, no dead ends can be achieved. Low energy consumption for turning and throwing - using a unique energy-saving transmission mechanism, the energy consumption is significantly lower than that of traditional turning and throwing equipment under the same workload. High degree of automation - Equipped with a fully automated electrical control system, no continuous operation by personnel is required during the operation of the equipment. The fermentation cycle is controllable - the temperature of each area of ​​the pile can be stably maintained in a suitable ripening range, and the fermentation cycle can be significantly shorter than traditional equipment.

Production capacity scale and adaptability
The large wheel compost turner has powerful processing capabilities and can meet the large-scale production needs of 10,000-ton fermentation projects. The equipment is designed through multi-wheel collaborative design and wide-width operation coverage, and a single piece of equipment can undertake the continuous turning task of large-scale fermentation projects. The equipment can be adapted to fermentation workshops of different sizes, and the turning span can be customized according to the width of the fermentation tank. The equipment supports 24-hour continuous operation and is an ideal choice for large-scale organic fertilizer production.

Target customer group
The demand groups for large wheel compost compost turners mainly include: production leaders and technical personnel of large-scale organic fertilizer production companies; operation managers of large-scale livestock and poultry farm manure resource utilization projects; investors of municipal sludge treatment and resource utilization projects; equipment purchasers of agricultural waste centralized processing centers; fermentation process leaders of compound fertilizer plants, gardening fields and Agaricus bisporus planting plants; and various large-scale production enterprises that need to carry out aerobic fermentation treatment of 10,000-ton organic waste.
