A salt deposit mostly consists of a mixture of chlorides and sulphates of potassium, magnesium and sodium, and calcium. In the raw materials Crystals of slightly soluble potassium chloride and magnesium sulfate (Epsom salt) can be found, as well as the accompanying salts magnesium chloride (hygroscopic) and sodium chloride (table salt), and the poorly soluble calcium sulfate (gypsum).
Our filter systems work underground mostly at belt transfers, belt airdrops, bunkers and screening stations. These top filters are manufactured for the use underground in a compact, pre-assembled design. With a supporting frame, the system is suspended below the mining ridge. By positioning it directly over the belt conveyors it is possible, to feed the product directly back after the separation of the dust from the air stream.
Of course belt conveyors acan be used overground for the loading of bulk goods by sea, by rail or trucks, too. Since there may be a variety of products which are loaded sequentially, mixing must be ruled out frequently. A specifically timed overrun of the jet cleaning prevents this, which all our top filters are equipped with. The principle of the direct product return to the conveyor system remains the same. To avoid caking on the housing by occurring humidity, these systems can also be equipped with an electric heating.
