Efficient Processing of Livestock Manure Fermentation Liquid
LW450x1845B Decanter Centrifuge Delivers Reliable Performance for Livestock Farm Waste Management Operations
Project Background
A livestock farm specializing in pig and chicken production needed an effective solution for processing mixed manure fermentation liquid. Their existing waste management system struggled with the varying characteristics of combined pig and chicken manure after fermentation, requiring equipment that could handle these challenging materials consistently.
Operational Challenges
- Separation quality varied unpredictably as manure characteristics changed between production cycles
- Wet sludge discharge meant higher disposal costs and more difficult material handling
- Frequent equipment breakdowns interrupted daily operations and affected production schedules
- Processing bottlenecks occurred during peak periods when manure volumes surged
- Environmental regulations required better solid-liquid separation than existing equipment could deliver
- Corrosive fermented manure was damaging equipment components and shortening service life
Our Solution
After analyzing the farm's waste characteristics and processing requirements, we recommended the LW450x1845B decanter centrifuge. This two-phase centrifuge configuration was selected for its ability to handle the specific properties of fermented livestock manure while providing consistent separation performance.
Equipment Design Features
-
Material Selection
Scroll and bowl constructed from duplex stainless steel with enhanced acid resistance. Wear-resistant tungsten carbide tiles protect high-wear areas from abrasive particles in fermented manure
-
Separation Technology
Two-phase decanter design optimized for high-solids organic slurries. Adjustable pond depth and scroll pitch provide precise control over residence time and cake dryness
-
Control System
PLC-based automation with variable frequency drives for both main and auxiliary motors. Torque monitoring prevents overload conditions during feed variations
-
Installation Requirements
Skid-mounted design for simplified installation. Vibration isolation and enclosed housing minimize noise and environmental impact for farm applications
Project Overview
- Customer Industry Livestock Agriculture
- Equipment Model LW450x1845B
- Actual Capacity 6m³/h
- Maximum G-Force 2913G
- Operating Speed 3400 RPM
- Installed Power 30kW
Installation Results
Since commissioning, the equipment has been handling the farm's daily waste processing needs. The installation includes three key project photos showing the centrifuge setup, operation, and separation results achieved on-site.
Operating Results
- Processing Throughput: Equipment runs steadily at 6m³/h, well within its 5-30m³/h design capacity and meeting daily farm requirements without strain
- Separation Quality: Liquid discharge shows noticeably clearer results with fewer suspended solids, helping meet environmental standards
- Solid Handling: Dewatered cake is drier and easier to transport, cutting disposal volumes and trucking costs significantly
- Uptime Performance: Equipment runs reliably through extended periods with routine maintenance keeping it operational
- Energy Consumption: Power usage stays within normal range for this type of equipment and application
- Regulatory Support: Better separation quality helps the farm stay compliant with waste discharge regulations
Customer Feedback
"This centrifuge has been running well for us since we got it installed. It does a good job with our pig and chicken manure mix, and we're seeing much better separation than before. The daily operation fits our schedule, and the stuff that comes out is much easier for us to work with when we're making compost. Took us a few weeks to get the settings right, but now it's doing what we need it to do."

Why This Equipment Works
Built for Farm Conditions
This centrifuge uses materials that can handle the harsh conditions of fermented manure. The design helps it last longer in the tough environment that farm waste processing creates.
Adjustable Operation
Operators can adjust the machine's speed and settings to match different manure conditions throughout the year. This flexibility helps get better results when feed characteristics change.
Right-Sized Equipment
The equipment size and capabilities match what most livestock farms actually need, giving effective separation without being overly complex or expensive.
Support When You Need It
We help with installation, train your operators, and provide maintenance support for farm applications. Our team knows the specific challenges of livestock waste processing.
Environmental Benefits
Better separation helps farms meet environmental regulations while reducing waste handling costs and making the whole process more manageable.
