The invention relates to a burner pipe for a rotary kiln for producing activated carbon and to a rotary kiln comprising said burner pipe.

The rotatable tube assembly comprises an outer tube and a second motor.

A plectrum extending from the rotation pipe is provided.

The invention further relates to the use of the burner pipe or rotary kiln for producing activated carbon.

The rotary shield or tube shutter on a first electrode (1) is open and said rotary shield or tube shutter (4) on a second electrode (2) is closed.

The tracking system includes a tube rotatable around its end-to-end axis.

The rotatable tube assembly comprises an outer tube comprising an upper portion configured to remain stationary and a lower portion configured to rotate.

The apparatus has a rotatable tube (5) for receiving biomass (108), an electromagnetic generator (7).

The chamber communicates with an interior passage (15) of a rotating tube (14) on which the tool is mounted.

In a second embodiment, a material sampling device comprises an auger, and a rotatable tube assembly.

A material sampling device comprises an auger, a first motor, and a rotatable tube assembly.

As well, a rotating pipe (50), having a slot (53) and a head part (52), is coupled to an end of the inner pipe (30), which reaches the head part (22) of the outer pipe (20).

A support tube (i) anchored in the ground, particularly removable in a foundation tube (k), is covered with a rotary tube (g) carrying in cantilever a support frame (B) of the paling screen made of planks (c).

We would also be very happy to supply you with rotary tubes in trial dimensions.
