General comment Typical mechanized vertical kiln cement plant.The production process of the vertical kiln is relatively simple. One of the raw materials, limestone, enters the crushed stone storage after crushing. The raw clay and iron powder enter the dry clay storage and iron powder storage respectively after drying. Fuel anthracite is crushed by the coal crusher (sometimes also dried) to enter the raw material storage, at the bottom of the storage by the downstream, metering equipment in proportion to the exact match and sent to the raw material mill grinding. After the qualified grinding, the raw material enters the raw material storage for homogenization and storage. The homogenized raw meal is combined with a suitable amount of water after metering, forming balls in the raw meal ball-making system, and then sent to the upper part of the vertical kiln, sprinkled into the kiln through the material distributor, and clinkered. The clinker from the kiln is stored in the clinic storage; the mixed material is also stored in the storage after baking in the drier; the gypsum is crushed and entered the gypsum storage. After being metered, the clinker, mixed materials, and a suitable amount of gypsum are sent to the cement plant for proportionate grinding. The ground cement is sent to the cement warehouse for inspection and final packaging or bulk delivery. |
