The High-performance Carbon Steel Dual Electric Engine Animal Manure Compost Grinder is a heavy-duty grinding device tailored for pre-processing animal manure and mature compost in organic fertilizer production. Its dual-electric-engine design (15 kW + 11 kW) delivers strong torque to break down clumpy manure (e.g., cow, chicken, pig manure) and semi-decomposed compost into fine particles (≤3 mm), solving the problem of uneven material mixing in subsequent granulation steps. Made of Q235 high-carbon steel (surface quenched to HRC 45), it withstands abrasion from fibrous manure components (e.g., straw in chicken manure) and supports continuous operation in harsh workshop environments. It is especially suitable for small to medium organic fertilizer plants that process fresh manure with high moisture content.
Product Features
Dual-Engine Power System: Two synchronized motors provide combined torque of 850 N·m, enabling efficient grinding of clumpy manure (up to 300 mm in diameter) with a processing capacity of 2-6 tons per hour.
Uniform Particle Size: The multi-layered blade system (12 movable blades + 8 fixed blades) ensures ≥95% of output particles are ≤3 mm, meeting the raw material requirement for organic fertilizer granulation.
Moisture Adaptability: Handles raw materials with 40-70% moisture content (common for fresh manure), thanks to the anti-clogging feed hopper (equipped with a vibrating device to prevent material bridging).
Durable Structure: High-carbon steel body (thickness 12 mm) and wear-resistant blade material (SKD11 alloy steel) reduce blade replacement frequency—blades last 1500 working hours for chicken manure, 2000 hours for cow manure.
Low Noise Operation: Equipped with a sound insulation cover and shock-absorbing rubber pads, the operating noise is ≤82 dB (measured 1m from the machine), complying with industrial workplace noise standards.
Applications
Pre-processing of fresh animal manure: Grinds cow/pig manure (mixed with straw) into fine material for aerobic fermentation, accelerating microbial decomposition.
Refining mature compost: Breaks down large compost clumps (formed during fermentation) into uniform particles, ensuring smooth feeding into granulators.
Soil improvement material production: Grinds decomposed garden waste (e.g., leaf compost) into fine powder for blending with organic fertilizer to enhance soil structure.
Small-scale biogas plant residue processing: Crushes biogas residue (high moisture, fibrous) into usable material for organic fertilizer, realizing waste recycling.
FAQ
Q: Can it grind manure with foreign objects (e.g., stones, wire)?
A: The machine is equipped with a magnetic separator at the feed inlet to remove metal fragments; however, stones ≥50 mm may damage blades—we recommend installing a pre-screening conveyor (optional) to filter large impurities.
Q: How to adjust the grinding gap for different materials?
A: The gap between movable and fixed blades can be adjusted via the side adjustment bolts (range: 0.5-5 mm). For fresh manure, set the gap to 2-3 mm; for dry compost, set to 0.5-1 mm for finer particles.
Q: Does it require a fixed installation?
A: Two installation options are available: fixed (anchored to the ground) for long-term workshop use, or mobile (mounted on a trailer with wheels) for on-site manure processing (e.g., at livestock farms).
Q: What is the power consumption per ton of material?
A: Average power consumption is 8-12 kWh/ton, depending on material moisture—lower moisture (40-50%) consumes 8 kWh/ton, higher moisture (60-70%) consumes 12 kWh/ton.

High-Moisture Adaptability & Anti-Clogging Design
Processing fresh manure often leads to severe machine clogging and frustrating downtime. This equipment is specifically engineered to handle raw materials with a staggering 40-70% moisture content. We have completely eradicated the issue of wet, sticky materials (like fresh chicken or cow manure) caking inside the machine.
Screenless bottom chassis design prevents wet material accumulation.
Active vibrating feed hopper breaks up material bridges before they form.
Ensures continuous, stable operation without the need for manual scraping or frequent halting.
Crushing Efficiency & Pre-Granulation Standards
The physical texture of your crushed material directly dictates the success rate and aesthetic quality of your final fertilizer pellets. Relying on the massive 850 N·m torque generated by the dual motors, this grinder pulverizes large, hardened compost clumps in milliseconds.
Animal manure is rarely pure; it is frequently mixed with highly abrasive straw, sand, and bedding materials. To combat this aggressive wear and tear, the machine's housing is forged from 12mm thick Q235 high-carbon steel, while the cutting blades are machined from premium SKD11 alloy steel.
Blade lifespan reaches an impressive 1500 hours for chicken manure and 2000 hours for cow manure.
Dramatically reduces the frequency of replacing wearing parts.
Minimizes maintenance downtime, significantly boosting the overall lifecycle return on your equipment investment.

Frequently Asked Questions (FAQ)
Can the machine safely process manure that contains foreign objects like stones or wire?
Yes, the grinder is equipped with an integrated magnetic separator at the feed inlet specifically designed to extract metal fragments such as wire and nails. However, to prevent damage to the SKD11 alloy blades from large stones (≥50 mm), we highly recommend installing our optional pre-screening conveyor to filter out heavy, non-metallic impurities before they reach the crushing chamber.
How difficult is it to adjust the grinding gap for different types of materials?
Adjustment is straightforward and external. Operators can modify the clearance between the movable and fixed blades using the heavy-duty adjustment bolts located on the side of the machine. The gap can be finely tuned anywhere from 0.5 mm to 5 mm. We recommend a 2-3 mm gap for wet, fresh manure and a tighter 0.5-1 mm gap for dry, mature compost.
Does this equipment require a permanent, fixed installation in a facility?
Not necessarily. We offer two distinct installation configurations to suit your operational model. For centralized, long-term processing plants, the fixed version is securely anchored to the concrete floor. For operators who need to process manure directly at various livestock farms, we provide a mobile version securely mounted on a heavy-duty trailer chassis with wheels.
What is the expected power consumption, and how does material moisture affect it?
The machine is highly energy-efficient, averaging between 8 and 12 kWh per ton of processed material. The exact consumption depends on the resistance offered by the material's moisture content. Drier materials (40-50% moisture) require less shearing force, consuming around 8 kWh/ton, while heavier, wetter materials (60-70% moisture) will utilize the full torque capacity, consuming closer to 12 kWh/ton.
How does the machine prevent clogging when handling 70% moisture fresh manure?
High-moisture materials typically cause bridging and caking in standard grinders. We solved this by implementing a screenless bottom discharge design, eliminating the mesh where wet materials usually get trapped. Additionally, the feed hopper is equipped with an active vibrating device that constantly agitates the sticky manure, ensuring a smooth, continuous drop into the cutting blades.
