Coal is a fuel and coal slime can also be burned at high temperature. Dajia developed H serise rotary coal slime dryer which adopts 4 stage drying process. In the first stage, coal slime is fed and impacted at the temperature of 600℃, most of the moisture is removed; in the 2nd stage, coal slime is repeatly scattered to avoid sticking on the wall at the temperature of 450℃, the coal slime won’t coking during this phase; in the 3rd stage, the coal slime is repeatly lift up, broken and falling down by the breaking device at the temperature of 300-400℃; in the 4th stage, forming negative pressure high-temperature hot air drainage area by the induced draft fan at a temperature of 150-250℃. The temperature at discharging port is 60-80℃. The calorific value will increase 1400kcal with water content 10% after drying process.
The slime dryer is composed of heat part, breaking part, belt feeder, feeding part, rotary drum, belt discharging part, fan, unloading part and distribution cabinet.
The slime dryer is mainly used to process the following material:
* Coal industry: slime, coal, flotation coal contrate, mixed coal;
* Construction industry: blast furnace slag, clay, limestone, sand, quartz;
* Or dressing industry: all kinds of metal ore, slag, tailings;
* Chemical industry: non-heat-sensitive materials.
Why select Dajia Slime Dryer?
As we all know, slime dryer is a large drying equipment with large output and energy consumption. With advanced technology as the basis, dajia slime dryer constantly improve its structure, ensure that equipment can bring higher profits. In the production process it no longer spend a lot of time and human resources. Dajia slime dryer become more intelligent, more convenient and simple to operate, get the praise from users.
Dajia slime dryer is capable of turning waste into treasure and can be employed to dry of limestone, slag, clay and other materials, enabling the use value of these materials. Dajia provide customers with the low-energy-consuming and high yield slime dryer to meet the development needs of society.
Large capacity, low fuel consumption, low drying costs;
High thermal efficiency: It adopts downstream drying. Both the heated gas and wet material enter the coal slime dryer from the same side, the high-temperature gas create strong evaporation and outlet temperature is comparatively low;
Operating parameters can be changed depending on the material properties, so that the material in the dryer cylinder body is capable of forming a stable full cut fabric curtain to get full heat exchange;
New feeding and discharging devices to solve the problem of feed clogging, not continuous, uniform and returning materials of the slime drum dryer reducing the load of dust removal system;
New internal structure, and strengthen the function of cleaning and thermal conductivity of the dispersed material, avoid material sticking on the cylinder wall;
It achieves "zero thrust" of this coal slime dryer, which greatly reducing wear of roller block, smooth and reliable operation;
Adopt "self-aligning roller-type device ", make roller and rolling ring linear touch forever, thus greatly reducing the wear and power loss;
The user can control the material particle size and moisture according to requirements, the finished slime moisture is less than 8%, and partical size can be controlled in 8mm.
