Therefore, the effective conditioning length for a single-layer conditioner is surely shorter than the
total length of the conditioner body.
However in a triple-shaft conditioner, since materials have been blended uniformly in the upper
layer before they enter the lower-layer conditioner, the effective conditioning length is equal to the
total length of this conditioner.
In summary, compared with the effective conditioning of a DDC, the triple-shaft conditioner:
Has one more conditioning layer offering extended conditioning time.
Utilizes the blending space of the DDC to hold more materials so as to promote the filling degree
and extend the conditioning time;
Extends the effective conditioning length to the total body length of the conditioner, thus
increasing the effective conditioning time.
It is due to the above reasons that the triple-shaft conditioner is superior to a DDC.
Compared with a large-diameter and slow-speed single-cylinder conditioner for extended
conditioning time, the triple-shaft conditioner can effectively make uniform blending and avoid the
material conglomeration and uneven material curing due to slow-speed push.
See Table 2-2 for the technical parameters of the triple-shaft conditioner.

Advantages of conditioning process:
(1)Promotion of production capacity
Since materials are partly cooked by the steam, the mechanical energy required to warm up the
products to the maximum temperature is much less. Therefore, its production capacity is much higher
than that of a dry-type in terms of a given power to the equipment.
