Inclined Screen Separator

Inclined screen dewatering machine relies on the gravity and permeability of the material on the inclined screen mesh. As well as the pressure generated by the weight and movement of the material itself, so that the liquid is discharged through the holes of the screen, while the solids move along the screen mesh for dewatering and separation. It can dehydrate 15-40m3 materials in an hour. And it has a wide range of application that is suitable for dehydrating materials with 90% moisture content. And it has a high efficiency of dewatering of 95%. therefore, if you have high demand of dewatering, then the inclined screen separator suits you best.

Multi-Plate Screw Press – Clean Separation & Strong Anti-Clogging

The multi-plate screw press uses a screw and moving plates to squeeze water from raw manure. Its self-cleaning plate structure prevents clogging and ensures stable operation. It can handle materials with 60%–98% moisture, especially manure mixed with sand, bedding, or fine fibers. The machine processes 8–25 m³/h depending on model size. And the final solid moisture rate remains around 30%–45%. Its biggest advantages are automatic cleaning, low washing-water demand, and long running cycles. The multi-plate screw press costs $3,000–$12,000. So it is suitable for farms that need continuous 24h dewatering.

Rotary Drum Dewatering Machine – Stable Output for Large Volumes

The rotary drum separator relies on a rotating perforated drum and internal scraper blades. As raw manure enters the drum, rotation spreads the material evenly. It works well with manure slurries containing 70%–95% moisture. The rotary drum separation equipment can handle 20–60 m³/h, ideal for large dairy farms, pig farms, and biogas plants. After separation, solids usually reach 35%–45% moisture, depending on the raw manure. Moreover, this equipment offers strong durability, easy maintenance, and high-capacity operation with fewer blockages. The price ranges from $4,000–$10,000, depending on drum size and power configuration.

What Raw Materials Can Be Processed With a Manure Dewatering Machine?

A manure dewatering machine handles a wide range of organic waste from farms, biogas plants, and fertilizer production lines. Different raw materials show different fiber levels, moisture content, and viscosity, but they all can be efficiently separated after matching the right type of separator.

Animal manure is the most common material processed by dewatering machines. Cow and pig manure have moderate viscosity and dewater easily through screw press separators. Chicken and duck manure contain finer fibers and higher moisture, so inclined screen or multi-plate separators achieve better separation. After dewatering, the solids become suitable for composting, pelletizing, or direct sale as organic fertilizer.

Biogas digestate contains a high amount of liquid and small suspended solids. A manure dewatering machine helps separate these fine particles to produce thicker solid fertilizer. The treated liquid can be reused or discharged after further processing, improving the efficiency of biogas plants.

When crop waste or silage becomes wet, it often contains long fibers. Drum and screw separators help remove excess water and produce fiber-rich solids suitable for fermentation or feed use. Dewatering improves storage stability and reduces transportation cost.

In industries such as brewing, papermaking, or starch processing, organic sludge has fine particles and high water content. Dewatering machines reduce moisture levels and help factories lower sludge treatment costs and meet environmental requirements.

How does the manure dewatering machine work?

Manure dewatering machine is a kind of machine that used for manure dehydration. Its main purpose is to separate solids and liquids in manure, thus facilitating further treatment and utilization of manure. The following is the basic process of manure dehydrator work.

Pretreatment Of Raw Materials.

First, putting fresh manure into a pump or let the manure flow into the pre-treatment device of the dehydrator. The pretreatment device usually contains screens to remove large particles of impurities in the manure, such as straw and stones. This allows for smooth subsequent dewatering. And then, using the mixing device to mix the manure evenly, which can reach a suitable solid-liquid ratio and more efficient separation.

Dehydrating Manure.

The prepared manure is placed into the extrusion device, which is accomplished by the screw driver. Under the double action of the gradual reduction of the spiral shaft and the blocking of the back pressure plate at the discharge end, the material is squeezed during the movement and the water is discharged through the screen. At the same time, the solid manures are squeezed out of the machine through the fine holes of the screen under the action of external forces, and the liquid part is drained through the screen to achieve solid-liquid separation.

Discharge Handing.

Solid manures are extruded into cakes or bars and discharged from the discharge port. You can use them as organic fertilizer or for further fermentation. And yuo can use the liquid parts to water crops or into the bioreactor for an aerobic digestion, generating biogas.
