A NEW ERA. It is the most widely chosen separation platform in the world. High through-put dewatering system delivering maximum dry matter recovery and trouble-free operation.
Manure separation is the most consequential and widely adopted dewatering decision in modern livestock management. The EYS Screw Press Separator range delivers the combination of high throughput and maximum dry matter recovery that defines class-leading separation performance. Standard models serve high-volume throughput requirements. HD models achieve the driest possible solids for bedding and composting applications. AISI 304 stainless steel screens and augers, user-friendly maintenance design, and thousands of proven installations worldwide make EYS the first choice for operations that think ahead.
As a global leader in dewatering technology, EYS has thousands of active installations performing reliably under extreme operational conditions. The EYS Screw Press Separators specialised design and construction handles all types of livestock manure slurries and biogas digestate with ease, yielding a high output rate of and consistently achieving high-percentage dry matter recovery. This results in a stackable solid fraction and a clarified liquid filtrate with significantly reduced total suspended solids (TSS).
Manure separation is not a peripheral management decision in modern livestock operations — it is the central dewatering process that determines storage efficiency, nutrient management capability, bedding material quality, environmental compliance, and the operational cost of handling the single largest waste stream any livestock enterprise generates. The EYS Screw Press Separator range is built on over two decades of separation engineering expertise, with thousands of units operating reliably under demanding conditions across global dairy, pig, poultry, and biogas operations. It is the most widely chosen separation platform in the world for one reason: it consistently delivers the combination of high throughput and maximum dry matter recovery that every separation application demands.
Standard vs HD: Matched to the Application
The EYS range addresses the two primary separation requirements that livestock and biogas operations present. Standard models — equipped with 0.65mm screens — are engineered for high-throughput separation of cattle and pig manure at the dry matter percentages common in working dairy and intensive livestock operations. They deliver drip-free separated solids at the throughput rates that high-volume operations require, with the operational reliability that continuous-use separation demands. Solids dry matter in the separated fraction consistently reaches 25–30% DM across standard cattle manure applications.
HD models are a fundamentally different engineering specification. Equipped with 1.0mm screens, HD-specification augers, and HD gearboxes, they are designed around a single performance objective: the driest possible separated solids for the most demanding applications. HD separation consistently achieves 35–40% DM in the separated solid fraction — the dry matter level required for effective bedding material production, for fast fermentation in composting applications, and for the solid handling and transport requirements that high-DM output enables. HD separators are the preferred specification for EYS Bedding Composter™ installations, where maximum solid dryness is the critical input parameter for fermentation process performance.
Screen and Auger Engineering: The Durability Advantage
The EYS performance reputation rests on two components that competing systems consistently compromise on: screen longevity and auger durability. EYS screens are manufactured from specially reinforced AISI 304 stainless steel — a material and construction specification that delivers the longest operational service life between screen replacements available in the separation market. The auger is manufactured from stainless steel with a special hard coating applied to the wear surfaces — providing resistance to the abrasive contact with the screen that determines auger service life under sustained operational loading. The practical consequence is fewer screen replacements, fewer planned maintenance interventions, less unplanned downtime, and a lower total cost of ownership across the operational life of the separator. Screen size selection from 0.3mm to 1.0mm provides the configuration flexibility to match separation performance to the specific manure characteristics, dry matter content, and output quality requirements of each application — without equipment substitution.
Maintenance Engineering: Designed for the Operator
EYS’s signature solid discharge mechanism — a slotted design specifically engineered for fast and easy service access — reduces the maintenance effort and downtime that conventional discharge mechanisms impose. The mechanism can be accessed and serviced rapidly without specialist tooling or extensive disassembly. Dual observation windows on both sides of the separator body provide continuous visual access to the separation process during operation — allowing operators to monitor performance, identify changes in solid discharge quality, and schedule maintenance interventions before performance degradation becomes operational disruption. The optional solid plug sensor adds an electronic monitoring layer to the visual observation capability — detecting solid plug formation in real time and providing the operational intelligence to prevent the blockages that cause unplanned downtime and component damage in high-throughput separation applications.
Application Versatility
EYS screw press separators handle all types of livestock manure — cattle, pig, and mixed — and biogas digestate across the full range of dry matter percentages encountered in commercial operations. The robust design manages the fibre structure variation, dissolved solid content variation, and consistency variation that different feed rations, retention times, and livestock species produce — delivering consistent separation performance across the conditions that real operations present rather than only the ideal conditions that laboratory specifications assume.
Beyond agriculture, the EYS platform serves biogas facilities, food processing operations, breweries, and pulp and paper industry applications — evidence of a separation engineering platform robust and versatile enough to perform across the most demanding industrial dewatering requirements. The optional full stainless steel body specification makes the system appropriate for the most hygiene-critical and corrosion-demanding of those environments.
Platform, Support, and Installation
EYS designs and manufactures custom separator platforms — including the SP400 self-contained platform and modular galvanised platforms for SP600 and larger models — to simplify installation, safe operation, and solid fraction handling at the separation point. Platforms incorporate built-in staircases for operator safety, and modular bolted construction for straightforward on-site assembly and future reconfiguration. Buffer tank options, air valve accessories, and configurable installation accessories allow the system to be integrated into new or existing manure management infrastructure with minimal site modification.
