Vertical Hydraulic Oil Sludge Press

60–75 MPa recovery press for viscous sludge

A vertical static high-pressure press built for viscous oil sludge, paste and settled residues that screw presses cannot handle. 60–75 MPa squeezes out recoverable oil and leaves a dry, disposable cake.

Pressing Force
60–75 MPa
Model
HN-Series

Product Overview

The oil sludge press is a vertical hydraulic machine for materials a screw expeller simply cannot process — sticky sludge, paste and settled residues that slip on the screw instead of being pressed. It works by static, low-temperature high-pressure extrusion at 60–75 MPa, which drives the oil out without friction heat or oxidation.

Recovered oil can be sold or re-refined, and the dry cake is far lighter to dispose of — it can often go to animal feed or fertiliser. A large barrel and multi-layer precision filtration handle the difficult consistency without blocking.

Structure & Build

Large barrel with multi-layer precision filtration

The oversized barrel and layered filter structure cope with thick, sticky material without clogging or material slippage — the two failures common on screw machines handling sludge.

Vertical static high-pressure hydraulics

Pressure is applied straight down and held, giving an even squeeze through the whole batch and a dry, uniform cake.

Key Performance Features

Handles the materials others reject

Built for viscous sludge, paste and settled residues that block or slip in screw presses.

Low-temperature static pressing protects oil quality

No friction heat means no oxidation or scorching; the recovered oil keeps better quality and value.

60–75 MPa for ultra-low residual cake

Thorough pressing removes the maximum recoverable oil and leaves a dry cake.

Cuts waste volume and cost

Recovered oil is resold or reused, and dry cake can become feed or fertiliser — a waste-handling cost turns into two saleable outputs.

One key, one operator

Feeding, holding, releasing and discharging are one-key automatic on a stable, durable frame; one worker runs the cycle.

Why Buyers Choose This Machine

This machine pays for itself from both ends: oil that used to be thrown away is recovered and sold, while the waste leaving the plant is a dry cake with a fraction of the original weight and disposal cost — often usable as feed or fertiliser. It is a four-in-one answer: oil recovery, waste reduction, cost saving and environmental compliance.

Questions About This Machine?

What is the price of the Oil Sludge Press?
Price depends on your configuration — for example single or dual barrel, motor and voltage, barrel size and optional accessories. Send us your raw material and your target daily output, and we will reply with a detailed quotation, usually within 2 working hours.
Can the Oil Sludge Press process my material?
This machine is designed for: Vegetable oil sludge (refining bottom sludge, crude sediment, frying waste, rapeseed/peanut/camellia residual sludge), animal grease residue (lard, beef tallow, slaughter and viscera sludge, catering waste), industrial oily sludge (mechanical sludge, waste engine-oil sediment, refining edge sludge), and kitchen/sewage oily waste.. If your material is not listed, send us a sample description or photo — the barrel and filter setup can often be adapted to it.
How long is production and how is the machine shipped?
Standard models are usually ready in 7–15 working days. Machines are packed in seaworthy wooden or plywood cases and ship from Qingdao port. We quote FOB Qingdao by default and can also arrange CIF or DDP to your nearest port.
Do you provide installation and after-sales support?
Yes. Most machines arrive fully assembled and need only power connection. We supply an English manual, online video guidance and spare-part support, and our engineers are available for overseas installation on request.
