The simple compost turning machine is a lightweight piece of equipment designed specifically for the fermentation of organic fertilizer and the treatment of livestock manure at small-to-medium-sized facilities; its core design philosophy emphasizes simplicity, practicality, low cost, and ease of operation. The unit straddles the guide rails on both sides of the fermentation trough; a motor drives the travel wheels to move the machine longitudinally along the trough, while rotating rake tines turn and aerate the organic material inside.
The machine features a simple, compact structure, consisting primarily of a turning mechanism, a travel system, a drive system, a frame, and a basic control unit. Constructed from high-quality carbon steel that has undergone rust-proofing and anti-corrosion treatment, the body effectively withstands corrosion from the fermentation materials. Compared to large-scale trough turners, this model eliminates complex hydraulic systems, PLC controls, and transfer carriage mechanisms, thereby significantly lowering both the initial investment cost and the complexity of operation and maintenance.
The working principle of the simple compost turning machine can be summarized as the synergistic action of mechanical travel and forced turning.
Once the equipment is started, the motor drives the turning drum to rotate at a low speed, allowing high-strength alloy rake teeth to penetrate the organic material within the fermentation channel. These teeth continuously excavate, scatter, break up, and shift the anaerobic material from the bottom layer toward the rear; this action brings bottom-layer material to the surface while sinking surface material to the bottom, ensuring thorough contact between the material and the air. This process maintains the compost pile at an optimal fermentation temperature of 55-70℃, rapidly eliminating pathogens and insect eggs.
The equipment features an adjustable travel speed of 5-0 m/min and a turning frequency of 3-8 passes per hour, allowing users to make flexible adjustments based on the specific fermentation stage of the material. When used in conjunction with a transfer carriage, a single unit can operate across multiple parallel fermentation channels, enabling one machine to service multiple channels.
This simple compost turning machine is compatible with the vast majority of solid agricultural and livestock waste materials. It can process various types of livestock and poultry manure——such as chicken, cattle, pig, and sheep manure——while also handling mixed fermentation with agricultural and forestry waste, including crop stalks, spent mushroom substrate, sawdust, and oilseed cake.
The equipment is widely used in the following scenarios:
Organic fertilizer plants——for the fermentation, decomposition, and moisture reduction of raw materials like livestock manure and sludge.
Livestock farm——for the centralized fermentation and treatment of manure, turning waste into a valuable resource and alleviating environmental compliance pressure.
Family farms and agricultural cooperatives——for producing organic fertilizer for on-site application, thereby reducing crop cultivation costs.
Horticultural nurseries and button mushroom farms——for the fermentation and preparation of growing substrates.
The equipment can be paired with solar fermentation chambers and transfer carriages to enable multi-channel operations with a single machine; the fermentation channels support both continuous and batch discharge.
Equipped with a simple control cabinet, push-button control, and supports manual start and stop and speed adjustment. Ordinary workers can operate it skillfully with simple guidance, and there is no need for professional technicians to be on duty.
Compared with manual turning of piles, a single machine can process 5-20 tons per hour, which can replace 8-10 strong laborers. The fermentation cycle is shortened from the traditional 30 days to 7-15 days, the fermentation efficiency is increased by more than 35%, and the uniformity of material decomposition reaches more than 90%.
The structure is simple, there are no wearing parts, and the failure rate is less than 0.5%. Routine maintenance only requires regular inspection of the wear of the turning and polishing teeth and cleaning of residual materials. A single maintenance should not exceed 40 minutes.
Strong adaptability and wide material compatibility
It can handle various organic fermentation raw materials with different humidity (38%-58%), and can flexibly switch materials without modifying the equipment. The tossing speed and depth can be flexibly adjusted according to the fermentation stage.
The frame is made of high-quality carbon steel, which has been treated for rust removal and anti-corrosion, and the flipping teeth are made of high-manganese steel wear-resistant material. The service life of the whole machine can reach 5-8 years.

The chain-type turning machine is a core equipment widely used in the fields of organic fertilizer fermentation, solid waste treatment, etc. Its core function is to achieve uniform turning of materials, ventilation and oxygen supply, and accelerated composting through chain conveying and turning operations.
The large wheel compost turner is a key equipment in the fields of agricultural environmental protection and organic fertilizer production. Its core function is to efficiently turn, stir and aerate the piled organic waste (such as livestock and poultry manure, straw, mushroom residue, sludge, etc.), accelerate the composting process of the materials, and at the same time achieve deodorization, sterilization and moisture content adjustment, and finally convert it into high-quality organic fertilizer.
The double-screws turning machine is used for fermenting and dump of organic wastes such as livestock manure, sludge garbage, sugar factory filter mud, dregs cake and straw sawdust.
