Wood briquette machine from China

A screw briquette press forms sawdust into a hollow log by friction and heat, and the screw tip wears fast doing it, so cost per tonne sits in screws, not the machine price.

What you are actually comparing.

Two quotes, one machine name

What hides inside the price

Screw extruder, piston or roller press

One name covers screw extruders, hydraulic piston presses and roller or ball presses for charcoal powder. Each makes a different product.

Screw material and hardfacing

Ask for screw steel, hardfacing method and the tonnes per screw the factory expects, then price spare screws.

Heating ring

The heated barrel softens lignin so the log binds. Ask heater rating and control.

Log shape and size

Hollow hexagon or square logs suit stoves and carbonising. Your buyer's stove or kiln decides the size.

Dryer and crusher upstream

The press needs dry, fine sawdust. Ask whether dryer and crusher are priced.

Before you ask for a price.

Send these with the enquiry. Without them, any number a factory gives you is a guess dressed as a quotation.

Raw material: sawdust, shavings or chips.
Measured moisture as it arrives.
Tonnes per shift.
End use: heating logs or charcoal feedstock.
Power supply and electricity cost.

Require this	A pass looks like
Run your sawdust for a counted hour and weigh output.	Output inside the stated kg per hour; logs do not crumble when dropped.
Measure screw tip dimensions before and after the run.	Wear per tonne recorded and consistent with the screw life written in the offer.
Log motor current and heater temperature during the run.	Both steady with no overload trips over the counted hour.

The documents that must arrive with it.

EU Declaration of Conformity, 2006/42/EC until 19 January 2027, then Regulation (EU) 2023/1230.
Wiring diagram and 2014/35/EU and 2014/30/EU references.
Wear part list with screw and sleeve drawings, so spares can be made locally.

The one people forget. Guarding for the screw and hot barrel. Buyers of your briquettes may ask for EN ISO 17225-3 grading, which tests the product, not the press.

When this is the wrong machine.

Buy something else if

Named, not hedged

You sell fuel for automatic boilers and pellet stoves.

A wood pellet mill. Automatic feeders take pellets, not logs.

Your sawdust arrives wet from a green sawmill.

A dryer first. A screw press without dry feed makes cracked logs and steam.

Where the numbers come from.

We name the kind of source, how many and when, and never the factory. Listed prices are asking prices, not landed cost. Where we do not hold a fact we say so: that is a GAP, not an estimate.
