Animal Manure Pellet Mill
Manufactured by RICHI, the MZLH series is a horizontal ring die biomass pellet mill specially designed for high crude fiber and low adhesion raw materials, including wood chips, crop straw and animal manure. With growing global environmental awareness, the animal manure pellet mill produces eco-friendly biomass pellets with higher calorific value than traditional coal. It is also widely applicable to livestock breeding and pet feeding industries.
According to different customer needs, RICHI designs different equipment models.
Manure Pellet Machine
Manure pelleting is one of the most mainstream applications of the MZLH series.
Animal Manure Pellet Production
Rich in crude fiber and low in viscosity, animal manure perfectly matches the structural characteristics of horizontal ring die biomass pellet mills. RICHI provides multiple models with hourly output ranging from 0.5t/h to 3.5t/h to meet diverse production demands.
The MZLH manure pellet machine converts chicken manure, cow dung, pig manure and other livestock waste into organic fertilizer or eco-friendly biomass fuel. The finished 3–6mm pellets feature moderate hardness and solid structure without loosening, making it an ideal solution for waste recycling. For manure processing, MZLH420 and MZLH520 are highly recommended.
Finished Pellet Diameter:4.0-12.0 mm

Equipment Structure
Manure pelletizer’s outstanding material compatibility and high output stem from professional optimized design, consisting of six core components
Forced Feeding System
Equipped with a material hopper and anti-bridging device to prevent arching and blockage caused by fluffy manure materials. The variable-frequency feeding screw operates with high torque and low speed, suitable for conveying wet and sticky powder. The manure pellet mill is professionally customized for light and bulky raw materials such as wood chips, rice husks and manure.
Conditioning System
When producing high-calorie biomass fuel pellets from manure, an optional conditioner can be installed for auxiliary heating and dehydration. It softens lignin to improve material forming performance, delivering high-density, drop-resistant and easy-to-store fuel pellets. No conditioner is required for organic fertilizer production.
Pelleting System
The MZLH series adopts large-diameter ring dies. The recommended MZLH420 and MZLH520 are equipped with 420mm and 520mm ring dies respectively. Numerous die holes and strong extrusion pressure realize binder-free forming for manure.
Wear-resistant wide-face press rollers offer powerful material grabbing force, ideal for manure, straw and fermented materials. The adjustable cutter enables pellet length control from 3mm to 12mm. The quick-open door with safety interlock ensures easy maintenance and automatic power-off for operational safety.
Transmission System
Fitted with heavy-duty hard tooth surface gearbox, the manure pelletizer delivers high torque and high transmission efficiency for non-stop continuous pelleting.
MZLH420 Main Motor: 90kW
MZLH520 Main Motor: 132kW
Built-in safety pin and hydraulic overload protection automatically shut down the machine in case of material jamming, protecting the motor and gearbox from damage.
Lubrication & Sealing System
An optional automatic oil injection system is available for simple daily operation. Multiple sealing structures for press rollers and main shafts effectively isolate manure dust and moisture, extending bearing service life.
Frame & Discharging System
The frame is welded with thick steel plates for effective shock absorption, low vibration and low noise. The discharge chute can be directly connected with coolers and conveying lines to support automated follow-up procedures.

RICHI Crafted, Fully Trusted.
Application Scenario
MZLH420: Best cost-performance for daily manure treatment of 50–80 tons.
MZLH520: Suitable for daily capacity over 80 tons and large-scale ten-thousand-ton annual output organic fertilizer plants, connectable with complete pre-processing, drying and cooling equipment to form integrated production lines.
Manure Treatment for Large-Scale Pig & Poultry Farms
Fermented pig manure and chicken manure are processed into organic fertilizer pellets, eliminating environmental pollution from waste discharge and creating extra profit from fertilizer sales.
Small & Medium-Sized Organic Fertilizer Enterprises
Take livestock and poultry manure as raw materials to mass-produce standardized pellet fertilizer. High-quality finished pellets greatly enhance market competitiveness.
Biomass Energy Projects
Process dried manure into clean fuel for boilers and power plants, achieving carbon emission reduction and comprehensive energy recycling.
Complete MZLH Production Line
Raw manure is centrally stored after collection, followed by fermentation, deodorization and sterilization. After pre-treatment, materials are transported to the production line via belt conveyors.
Pre-treatment
Screened raw materials are ground into qualified particle size via water drop hammer mills, vertical grinders and small crushing equipment.
Crushing
Crushed materials are fully blended with multi-type mixers (single-shaft double-layer blade mixers, twin-shaft blade mixers, etc.) per production requirements.
Drying
Raw materials are conveyed by variable-frequency feeders to conditioners for steam humidification and maturation, then pressed into pellets in the pelleting chamber.
Pelleting
Fresh pellets are hot and soft; a counterflow cooler reduces their temperature and hardness increases for safe storage.
Cooling
Fines and unqualified pellets are separated and returned for re-processing, ensuring consistent quality.
Screening & Packing
Finished pellets are weighed and packed using automatic packing machines for storage or sale.

FAQs
Should you have any questions, RICHI will provide you with professional answers.
What is the actual output of MZLH420 and MZLH520 for fermented chicken and cow dung with 28% moisture?
Both models are professional pellet mills for organic fertilizer and manure processing. For fermented livestock manure with 25%–35% moisture:
MZLH420: Stable output of 6–8 t/h
MZLH520: Stable output of 9–12 t/h
Supported by forced feeding and high-torque gear transmission, they operate continuously and stably for high-organic and high-fiber manure materials.
As an EU farm with strict environmental standards, can these two models process massive manure and meet local emission regulations?
Yes. Pelleting reduces manure volume by more than 70% with zero leakage and odor diffusion. The fully enclosed structure is compatible with dust removal systems to meet EU dust and odor control standards. Finished pellets are easy to store, transport and apply on farmland, fully complying with EU manure resource utilization regulations.
Service life and replacement convenience of ring dies and press rollers under manure working conditions?
Ring dies and press rollers are made of 42CrMo alloy with carburizing heat treatment for enhanced wear resistance. Under normal fermented manure working conditions, their service life reaches 500–1000 hours. The hoop-type quick-install ring die allows fast replacement by ordinary workers. RICHI provides global original wearing parts supply with unified specifications and stable delivery cycles.
