III technical specifications

1.  The technique request about productivity

It can be made clear that the productivity of asphalt mixing plant is that under

 the standard conditions, it must fulfill the requirements as below simultaneously:

(1) Environment temperature:20℃, standard atmospheric pressure;

 (2) The average humidity of Cold aggregate<5%;

(3) The temperature of the hot mixture<160℃;

(4) The mixture is of middle size, the density of stone material≥ 1600kg/m3

(5) The content of sand material in mixture<35%; 

(6) The product capability includes asphalt; 

(7) The stone aggregate must accord with the proportion requirements of

 national technical specifications.

(8) The cold aggregate must be clean, and it shouldn't include more soil and

 sundries. The cold aggregate supply should be continuous.

(9) The cold aggregate shouldn't include large quantity of oversize grain; 

otherwise it will cause jam and reduce the aggregate supply capability.

IV. Attention contents

1. Because of the continuous creation and improvement on the technology and 

manufacturing techniques, our company has rights to change this configuration 

and specification before the customer choosing model and ordering, and without

 notifying the customer who had gotten this configuration and specification but 

haven't ordered. Please consult our company before ordering. At the premise 

of guaranteeing the plant's funciton and capability, some 

specificaiton or power maybe changed in above specificaiton with 

the continous improvement of the product, and we will not infrom

 the clients about this change again. 

2.  The dust collector equipped can only be applied in the area where there is no 

strictly restriction for the dust collector; we should choose bag dust catcher if higher

 environmental standard is required.

3. in view of asphalt will be solidified under low temperature, the 

clients are suggested to clean the asphalt pipes with diesel repeatedly

 after production to prevent remaining asphalts in them; asphalt pipes 

could be used only after being heated if there is remained asphalts in them.
