The DEL/DEM type quantitative feeder is the fourth generation of variable frequency speed control quantitative feeder that our company quotes from Germany Schenck technology, fully absorbs and adopts the technical production of German Shenke Company. The indicators exceed the domestic similar products and reach International advanced level. With high precision and reliable performance, it is used to transport bulk materials. The rugged design makes it particularly suitable for use in harsh conditions. For the specific working conditions, the most difficult problems in the feeding can be solved economically with the corresponding structure. Widely used in cement, metallurgy, chemical, coal, ceramics, food, tobacco, pharmaceutical and other industries.

principle:

        The conveyor belt load and speed signals are sent to the microprocessor controlled measurement, control and regulation system for processing, continuously comparing the actual feed rate with the set feed rate, thereby controlling the speed of the conveyor belt to keep the feed rate constant On the level.

System Features:

● High-resolution load cells with a displacement of at least 0.1 mm ensure accurate measurements.

● High resolution digital pulse speed sensor ensures accurate speed values.

● Gravity automatic tensioning device ensures constant belt tension and avoids belt slippage and excessive tension.

●The belt automatic correcting device avoids the production due to belt deviation.

● Pear-shaped scraper clears the debris on the lower belt to one side, avoiding damage to the belt due to debris between the belt and the roll surface.

●The scraper inside and outside the belt avoids belt adhesive and tare changes.

● No need for assistance, belt replacement is convenient, and maintenance is simplified.

●The main and slave rollers are equipped with self-aligning bearings, which is very convenient for installation and adjustment.
