1. Purpose of the storage bin.
When fracturing more than 150 tons, storage bunkers (BIN) are used for proppant. BIN is a vertical container of round or square section, up to 33 m3.
2. The composition of the storage bin.
Inside the container is divided by a blind partition, for the possibility of using proppant of different fractions. The bottom of the tank is raised above the ground to a height of more than 1 meter and has a large slope, for fast falling asleep proppant. As a locking device used in the damper with manual drive. To direct the flow of proppant into the hopper or sand belt, removable troughs are installed on the hopper. With a volume of 33 m3, the hopper capacity is about 50 tons of proppant, depending on the fraction.
