It is designed for drying bulk materials with flue gases. It is used in the production of building materials, in various lines for thermal drying of limestone, clay, sand, chalk and other bulk materials with a particle size of up to 60 mm. A dryer with a single drum with a contact area of the heated metal of at least 10 m3 per 1 ton of dried fraction, with an angle of inclination of 1-3 degrees. The angle of inclination is adjustable. Also, using a frequency converter, the speed of rotation of the drum is adjusted. "BSP-7" operates on diesel or natural gas.
The installation works simply: the drying of a specific material is carried out in a drum container, which is constantly rotating. There are blades inside the container - thanks to them, the contents are well mixed. It constantly moves between the blades and loses moisture due to the flame of the burner supplied to the drum container.
The key components of the BSP-7 are the drive mechanism and the drum, fixed on a fixed frame. The drum is made of ST-3 steel and equipped with shelves inside - their features and position inside the structure are determined by the product being dried. The outer part of the drum is equipped with bandages supported by four rollers of the drive mechanism. Due to the location of the rollers, sagging of the drum cavity is excluded. Initially, the product requiring drying enters the drum cavity via a conveyor, into the part of the drum container where the flame is supplied at that moment. In the process of movement inside the drum, the raw product is uniformly dried and then enters the unloading chamber, from which it leaves for the required section of your production dry. The gases processed during the drying process are discharged from the mechanism into the atmosphere. The dry material at the outlet has a temperature of 80-120 0С.
The design features of this model give it the following advantages:
- "BSP-7" consumes less electricity, being 2-3 times more productive in comparison with dryers of the same volume;
-The structure is easily installed and assembled at the required production point and does not require the construction of capital buildings to start work;
- Ensures good quality drying at the output – without sticking or lumps, even if the original product was very wet or mixed with debris.
Considering that the cost of drying sand "BSP-7" is extremely low, this drum dryer is an excellent solution for your production - reliable, simple and productive!
