1. The product design conditions and use control matters

Production capacity refers to the production capacity of the equipment under standard conditions, that is, the following conditions are met at the same time:

A. The ambient temperature is 20°C; the standard atmospheric pressure; the altitude is not more than 1000m; the altitude of the fan is not more than 1000m, if it is higher than this requirement, please notify our company for redesign;

B. The average moisture content of cold aggregates is less than 5%;

C. Hot aggregate temperature <160℃;

D. The finished material is medium grain type, that is, the bulk density of the stone is ≥1600kg/m3;

E. Sand content <35%;

F. The aggregate in the stockyard should meet the proportional requirements of the relevant national technical specifications. Cold aggregate dust content ≤ 3%;

G. The cold aggregate must be clean and free from excessive soil and debris. The gradation of cold aggregate should be continuous;

H. The cold aggregate must not contain a large amount of over-spec material, otherwise it will cause the channel to be blocked and the feeding capacity will decrease accordingly;

I. The moisture content of the powder must be less than 0.5%, and there should be no agglomeration and arching, otherwise the phenomenon of material breakage and waiting will be formed, thereby affecting the output;

J. Asphalt should have good coating properties. During the standard mixing cycle, the aggregate should be completely and evenly coated with asphalt, and the asphalt temperature should be controlled within the range of 150℃±5℃ (ordinary asphalt).

K. Other aspects that affect production capacity:

a. Different environmental conditions or characteristics of aggregates in a specific environment will also lead to significant changes in yield;

b. The output of the drying drum must be calculated by the amount of material flow at the outlet of the drum and the amount of recovered dust;

c. When a screen is used, the output may be reduced due to the size of the screen used, the gradation of the aggregate and the formula used;

d. The output of the mixing pot will vary due to many parameters, such as the aggregate gradation, the nature and size of the aggregate, the affinity of the aggregate and the asphalt, the amount of powder and asphalt, the mixing temperature, the addition of additives and the asphalt in the formulation. The proportion of recycled materials, etc.

E. If there is a heat-conducting oil furnace in the equipment, the heat-conducting oil should be prepared by the user. The temperature class is 320℃. The control cabinet of the heat-conducting oil furnace and the transformer cable should be prepared by the user.

F. The power system adopts AC three-phase 380V, 50Hz, and is powered by a single-circuit three-phase four-wire system. If there are special requirements, it should be specified in the contract.

G. Other required equipment, tools and work not described in this specification.

H. According to the regional conditions, the lightning protection grounding facilities are the responsibility of the user unit.

Ⅳ.Special instructions
