Fertilizer Lump Chain Crusher for Organic Compost
What Is the Fertilizer Lump Chain Crusher for Organic Compost？
The Fertilizer Lump Chain Crusher for Organic Compost is an impact-type crusher designed for breaking down lumpy materials in organic compost production. In March 2026, we commissioned an LP800 model at a 30,000-ton/year organic fertilizer plant in Henan. The machine processed fermented cattle manure at 48% moisture with feed sizes of 80-100 mm at 900 rpm, achieving a throughput of 6.5 tons per batch with all discharge particles below 3 mm. Fermented compost often forms large agglomerates that cause uneven granulation and low yield.
This equipment uses high-speed rotating chains to impact, tear, and shear agglomerates into fine particles suitable for granulation. Feed size normally does not exceed 100 mm, and discharge size can be controlled within 3 mm, with 70% to 90% meeting this standard. Hourly capacity ranges from 1 to 15 tons. Product-contact parts feature high-strength chains and anti-stick liners, suitable for livestock manure, straw, municipal sludge, distiller's grains, and mushroom residue.
How Does Fertilizer Lump Chain Crusher for Organic Compost Work？
The core component is a rotor with steel ring chains. The motor drives the main shaft at high speed, with chains rotating at 28 to 78 m/s. Material enters the crushing chamber where high-speed chains generate impact forces while particles also collide, breaking down agglomerates. Material meeting size requirements is discharged, while oversize material continues to be impacted.
The equipment is available in vertical single-rotor and horizontal double-rotor configurations. In the double-rotor model, two shafts are driven by independent motors in opposite directions, allowing material to undergo two or more impacts for higher efficiency.
How Does Fertilizer Lump Chain Crusher for Organic Compost Fit in the Production Line？
Fertilizer lump chain crusher for organic compost forms a complete process chain with upstream and downstream equipment. Material is evenly fed via a feeder for primary crushing, where large agglomerates and long fibers are cut. The increased surface area after crushing improves contact between microorganisms and air, accelerating fermentation. Crushed material is mixed uniformly with microbial agents in a horizontal mixer for granulation. If fertilizer re-agglomerates after drying, the product performs secondary light crushing to restore a loose state for screening and packaging.
Fertilizer Lump Chain Crusher for Organic Compost Technical Specifications
The Fertilizer Lump Chain Crusher for Organic Compost is available in multiple models to meet various production requirements.
| Model | Structure | Feed Size | Discharge Size | Motor Power | Capacity |
|---|---|---|---|---|---|
| LP500 | Vertical Single Rotor | ≤60mm | ≤3mm | 11kW | 1-3 t/h |
| LP600 | Vertical Single Rotor | ≤60mm | ≤3mm | 15kW | 2-5 t/h |
| LP800 | Vertical Single Rotor | ≤60mm | ≤3mm | 22kW | 5-8 t/h |
| LP800 II | Horizontal Double Rotor | ≤100mm | ≤3mm | 18.5×2kW | 10-15 t/h |
The body is made of Q235B steel, and chains are manufactured from 25Mn carburized steel with wear-resistant tips, achieving HRC55 hardness. The housing is lined with rubber or polypropylene plates to prevent material adhesion. Speed can be adjusted via a belt drive, with a recommended range of 800 to 1200 rpm. Quick-opening inspection doors are installed for maintenance. Measured noise ranges from 75 to 82 dB.
What Core Advantages Does Fertilizer Lump Chain Crusher for Organic Compost Offer？
The Fertilizer Lump Chain Crusher for Organic Compost delivers high crushing speed, lower energy consumption, effective anti-sticking performance, and low investment cost, making it a cost-effective choice for organic fertilizer production.
High crushing speed. High-speed chains produce uniform discharge with 70% to 90% below 3 mm. Single-batch time ranges from 5 to 10 minutes
Lower energy consumption. Under specific conditions, energy consumption is reduced by 15% to 20% compared to hammer crushers
Anti-sticking design. Centrifugal force prevents material adhesion. The screenless design eliminates clogging, and anti-stick liners form a physical barrier
Low investment cost. Chains are the only wear parts. Investment cost is approximately 60% of comparable hammer crushers
What Materials Is Fertilizer Lump Chain Crusher for Organic Compost Suitable For？
For livestock manure such as chicken, pig, cattle, and sheep manure that has formed agglomerates, the Fertilizer Lump Chain Crusher for Organic Compost handles sticky materials with moisture up to 50%.
For straw and agricultural residues, high-speed chains produce shearing and tearing effects on fibers, eliminating fiber entanglement issues common in hammer crushers. For industrial and municipal wastes such as sugar filter mud, distiller's grains, vinegar residue, and mushroom residue, magnetic separators and bar screens should be installed before feeding if stones or metals are present. For fermented compost, this equipment breaks down agglomerates into the particle size required for granulation, serving as a key link between fermentation and granulation.
How Does the Fertilizer Lump Chain Crusher for Organic Compost Differ from Other Crushers？
The Fertilizer Lump Chain Crusher for Organic Compost stands apart from semi-wet crushers and hammer crushers in its ability to handle fermented agglomerates with moderate moisture and high-fiber materials without clogging, making it the preferred choice for specific organic fertilizer applications.
Semi-wet crusher handles sticky materials with 30% to 60% moisture using a double-rotor impact principle
Chain crusher is better suited for fermented agglomerates with moisture up to 50%
Hammer crushers are prone to fiber entanglement and screen clogging when processing fibrous materials
Chain crusher produces shearing effects on fibers, avoiding entanglement and offering advantages when processing high-fiber materials like straw
Selection Recommendations
| Material Type | Moisture | Recommended Model | Notes |
|---|---|---|---|
| Fermented Cattle/Pig Manure | 40% to 50% | LP800 | For large-scale plants |
| Fermented Chicken/Sheep Manure | 35% to 45% | LP600 | For small to medium farms |
| Straw and Fiber Materials | Any | LP600 or LP800 | Requires pre-cutting |
| High-Moisture Sticky Materials | 30% to 60% | Semi-Wet Crusher | Chain crusher not suitable |
What Boundary Conditions Should Be Considered？
The Fertilizer Lump Chain Crusher for Organic Compost performs optimally below 20% moisture. At 20% to 50% moisture, efficiency decreases. Above 60%, efficiency drops significantly, and drying is recommended. For dry, hard inorganic materials, efficiency is lower than hammer crushers. Stones and metals may cause chain breakage, so magnetic separators and screens should be installed at the feed inlet. Using 25Mn carburized steel chains with wear-resistant tips extends service life, with replacement intervals of 800 to 1,200 operating hours. Actual life depends on material hardness, moisture, and operating duration.
