VLJ型盘塔式机械立窑 Mechanical Tower Shaft Kiln

立窑是水泥行业用来将水泥生料煅烧成水泥熟料的主要设备。

Shaft kilns are the main equipment used in cement industry to burn cement raw material into cement clinker.

机械立窑是指采用机械加料和机械卸料的立窑。入窑物料由成球机制成直径为5~10mm，水分在12~14%的料球，由加料装置从顶部喂入窑内，窑内整个空间充满着物料，物料自上而下运动，而气流则从底部吹入，自下而上地通过物料层。物料在窑内经过干燥、预热、分解，烧成和冷却等过程。烧成后的物料经过窑体底部卸料篦子的破碎作用，破碎成小块经卸料密封装置，排出窑外

Mechanical shaft kilns are shaft kilns which adopt mechanical loading and mechanical unloading. The materials entering the kiln are made through ball forming mills whose diameter is 5 to 10mm. The pellets whose moisture content is 12% to 14% are fed into the kiln by the feeding device from the top. The whole kiln is filled with materials. The materials move from top to bottom while the air flow blows from the bottom and passes through the material layer. In the kiln, the materials undergo processes such as drying, preheating, decomposing, sintering, and cooling. Under the crushing action of the discharge grate at the bottom of kiln, the sintered materials are crushed into small pieces which are discharged out of the kiln through the discharging sealing device.

机械立窑的优点是：由于在窑内物料与热气体直接接触，热效率高，可达45%，热耗低，一般为3550~4000千焦/千克燃料。

The advantages of mechanical shaft kiln are: Due to direct contact of materials in the kiln and hot gas, its thermal efficiency is high, as high as 45%. Its heat consumption is low, normally consuming 3,550~4,000 KJ/Kg of fuel.

盘塔式机械立窑是我厂经广泛收集国内现有窑型的特点，于1986年在原有塔式立窑的基础上开发的新型立窑。

Mechanical tower shaft kilns are a new type of kiln developed by our factory on the basis of the original tower shaft kilns in 1986, after extensively gathering information about the existing kiln type in China .

该窑煅烧质量好，一般可达500号以上，而且产量较高。

Such kiln features high burning quality, usually reaching 500. Besides, it has large productive capacity.

盘塔式立窑由喂料部、窑体、盘塔式卸料装置、传动部等部分组成。

Tower shaft kiln is composed of feeding part, kiln body, tower discharge mechanism, driving part, etc.
