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.

(10)The asphalt should be with well wrapping capability, during standard mixing circle, the aggregate 

should be completely wrapped by asphalt; the asphalt temperature should be controlled within the

 scope of 150℃±5℃. 

 

2. The requirements for fuel:

A. Light oil: diesel oil,heat calorific power is no small than 46055kJ/kg; 

B. The heavy oil model is determined according to the selected main burner, heat calorific power 

is no small than 46055kJ/kg The customer needs to purchase heavy oil according the oil quality

 standard, and require the oil supplier to provide oil quality essay or the correlative certificates. 

The using fuel must have well burning and pulverization capability. Forbid using kinds of causticity 

fuel or the products from unqualified oil producing factory. (All the burner damage or failure that 

caused by diesel or heavy oil quality problem, the correlative damaged spare parts and customer 

oneself should afford the repair expense.

3. Items of the customer equipped himself

(1) The transformer, and also the cables from operation platform to transformer 

should be equipped by customers supplier can provide the type and requirement of the cable for

 reference. Calbes from operation platfrom to the plant will be supplied by Longda. 

(2) The customer should build the foundation according to the load requirements and the foundation 

drawing provided by the supplier. The customer can increase or deepen the foundation concrete or

 redesign the plant installation foundation and accessory establishments.

(3) The crane, power supply, electric welding equipment and other necessary instruments, material

 used for installation; the lube and grease for the equipment, the material used for foundation.

(4) The required material during debugging and producing, sand, stone material, asphalt, fuel oil, 

heat transmitting oil, dumping car, loader and operator etc. the necessary test and assay.

(5) The power supply system should adopt AC380v, 50Hz and single loop three- phase four-wire type, if there is any special requirement, it should indicate in the contract.

(6) The other required equipment, instrument and work not mentioned in this configuration and 

specification.

(7) According to the actual situation, the customer should be responsible for the anti-thunder device and earthing equipment himself.

 

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;
