Hydraulic Type Groove Turning Machine
Introduction:
This hydraulic type groove turning machine is used for fermenting and dumping of animal manure and other organic wastes, such as livestock manure, sludge garbage, sugar factory filter mud, dregs cake,etc
Introduction:
The hydraulic compost turner is the core piece of equipment for achieving "deep-layer turning and comprehensive oxygenation" in aerobic composting processes. Powered by a hydraulic drive system and equipped with either a trough-based or crawler-type travel mechanism, it performs turning, crushing, oxygenation, and displacement of organic materials—whether in fermentation troughs or windrows. The equipment offers significant turning depth, deep oxygen penetration, and uniform fermentation, while ensuring the smooth, steady movement of material within the trough.
During aerobic fermentation, the hydraulic compost turner serves not merely as a tool for mixing, but as the "operational brain" of the process; by precisely controlling turning depth, frequency, and displacement speed, it creates the optimal growth environment for aerobic microorganisms. It can rapidly raise the temperature of the compost mass to over 70°C within 48 hours—effectively eliminating pathogens, insect eggs, and weed seeds—and significantly shorten the fermentation cycle to just 7–20 days. Positioned between the solid-liquid separation and the maturation/screening stages, the equipment acts as the "primary arena" for the aerobic biochemical reaction.

Detailed Explanation of the Aerobic Fermentation Process
From the perspective of the fermentation process, the hydraulic compost turner can be categorized into the following functional units:
(I) Turning and Aeration Unit: Composed of a turning drum (or chain plate/auger shaft) driven by a hydraulic motor and fitted with alloy mixing tines arranged in a spiral pattern. It is responsible for deeply scooping, loosening, breaking up, and throwing the material.
(II) Oxygen Supply and Aeration Unit: Achieves natural oxygenation through thorough contact between the material and the air during the turning process. The turning action extends the material's exposure time to the air, eliminating the need for an additional high-pressure forced aeration system.
(III) Displacement and Conveying Unit: Uses spirally arranged paddles on the drum to push the material forward while turning it, enabling continuous lateral movement of the material within the fermentation channel or facilitating its discharge.
(IV) Depth Adjustment Unit: Controls the operating depth of the turning drum via a hydraulic lifting mechanism.
(V) Travel and Positioning Unit: A travel system that moves along the fermentation channel rails, ensuring the turning operation covers the entire length of the channel.
The hydraulic compost turner plays a central role in the fermentation stage of an organic fertilizer production line. The complete production process flows as follows: raw material pretreatment (proportioning and mixing) → aerobic fermentation (hydraulic turning) → discharge → crushing → granulation → drying → cooling → screening → packaging.
During the fermentation stage, the hydraulic compost turner performs several critical tasks: it facilitates thorough mixing of materials between the upper and lower layers of the compost pile through deep turning; it ensures full contact between the material and the air through a throwing action, rapidly replenishing oxygen while expelling water vapor and exhaust gases; it breaks up compacted material; and it gradually advances the material from the feed end to the discharge end. When used in conjunction with a transfer carriage, a single machine can service multiple fermentation bays.
The aerobic fermentation process facilitated by hydraulic compost turners represents the core technical stage of organic fertilizer production.
Fermentation temperature management: The aerobic fermentation process typically comprises three phases—a heating-up phase, a high-temperature phase, and a cooling-down phase. The hydraulic compost turner achieves temperature uniformity throughout the pile by deeply turning and mixing the materials: oxygen-deprived "cold material" from the bottom is moved to the surface, while dry "hot material" from the surface is buried within the pile. In conjunction with the ventilation system at the bottom of the fermentation channel, the pile temperature can rapidly rise above 70°C within 48 hours and be maintained at a uniform, high-temperature maturation range of 55–65°C.
Oxygen supply mechanism: During the turning process, the hydraulic compost turner uses a high-speed rotating drum to toss materials into the air, ensuring extensive contact between the material and the atmosphere. This process replenishes oxygen evenly and without "dead zones," providing strong oxygen penetration throughout the material layers. This method eliminates the need for additional high-pressure forced-air supply systems.
Fermentation cycle control: Traditional fermentation cycles typically exceed 30 days. With the use of a hydraulic compost turner, the fermentation cycle can be shortened to 7–15 days. The material is turned 1–2 times daily at a speed of 2–5 meters per minute.
Operational Guidelines and Key Control Points
Proper operation of the hydraulic compost turner is crucial for ensuring fermentation quality and equipment longevity:
Pre-start preparation: Check that the hydraulic oil level meets the standard requirement. Inspect for loose bolts or broken welds. Verify that the electrical control buttons operate smoothly and reliably. Ensure the area around the equipment is clear of personnel and obstacles.
No-load test run: Start the machine without a load; starting it while loaded is strictly prohibited. Check the direction of rotation during the no-load run; the motor must rotate in the direction indicated by the arrow on the nameplate.
Loaded operation: Start the main motor and adjust the turning depth and travel speed according to the material characteristics. Ensure the material is free of entangling objects such as wire. Stop the machine for inspection if any abnormalities occur during operation.
Shutdown procedure: Stop forward movement before shutting down the machine; stopping while loaded is strictly prohibited.
Requirements for Material Pre-treatment and Proportioning
Requirements for Material Pre-treatment and Proportioning
Hydraulic compost turners have specific requirements regarding the input materials. Moisture content control: The moisture level must be maintained within an optimal range (typically 50%–65%), as levels that are too high or too low will impair the fermentation process. Carbon-to-nitrogen (C/N) ratio adjustment: The C/N ratio of the raw materials must be adjusted during fertilizer production, requiring the addition of a certain proportion of auxiliary materials. Inoculation for fermentation: Livestock and poultry manure can be mixed with microbial fermentation agents or previously fermented compost material.
