立式薄膜干燥器由一个内部带有加热套的圆柱形垂直布置的主体和一个转子构成。转子在整个干燥器的长度上配备有数排摆叶片。铰接的叶片将湿进料产品在加热的壁上以一层薄薄的产品层展开，并将产品层材料强烈地混合。因此，挥发性组分从蒸发速度高的物料层中连续蒸发。 铰链叶片设计有最小的间隙，以防止加热面被产品脏污，但同时又不会与加热壁相接触。 产品进入干燥器顶部。加热至沸点后蒸发便开始。初始固体会在浆料区形成，并随着挥发物的蒸发以及铰接叶片的继续剪切，糊状物料继续分解成粉末。 最终的固体产品通过重力、由合适的气闸在干燥器的底部排出。 立式薄膜干燥器的独特优点是： 从液体到固体一步完成 产品滞留少 停留时间短，对产品退化的影响最小 快速启动和停机 比例缩放后相同的高性能 典型应用 立式薄膜干燥机用于许多应用： 氯化物、溴化物、硫酸盐 甘油回收 碳酸盐、磷酸盐 硅烷回收 硅、碳化硅 甲酸钠（盐） 农药（莠去津等） 废水和饮料 苯磺酸 从废物中回收溶剂 黄原酸盐 染料和颜料 冶金碳化硼、氮化硼 食品、咖啡因、调味品

Alloy Cast Steel Roll materials are eutectoid steel and hypereutectoid steel. Adding alloy content such as Cr, Ni, Mo, and V up to more than 0.8%, carbon content 0.4~1.3%. The matrix structure, after heat treatment of normalizing and tempering, becomes sorbite and tempered sorbite. This type of steel mill roll possesses high strength, good toughness, good resistance to hot cracking, and strong impact resistance. The cast steel roll employs monoblock casting process (single pour): Melting-Casting-Heat Treatment-Machining-Flaw Detection-Finished Products. It can be work rolls for blooming and slab mills, section roughing mill rolls, as well as backup rolls for hot-strip steel rolling mills. TINVO's alloy cast steel mill rolls conform to international standards, including ISO, GB, ASTM, DIN, and JIS.

Bainitic Nodular Cast Iron Roll Introduction Bainitic nodular cast iron roll is a kind of spheroidal graphite iron roll, which is known as ductile iron roll and is a roll made by spheroidizing the molten iron with magnesium and pouring it into the sand-lined cold type. Due to the spheroidizing treatment, the graphite carbon inside the cast iron is changed from flake to spheroid, which eliminates the phenomenon of graphite tip stress concentration caused by flake graphite, which significantly improves the strength of cast iron, similar to the cast steel roll, but the abrasion resistance is much higher than the cast steel roll. There are three types of nodules of magnesium, cerium, and calcium, and magnesium is commonly used. Spheroidal graphite iron roll can be applied in open-rolling mills, roughing mills and rolling mills before finishing rolling on various sections and plates. When the finished roll bears a large load, it is best to use a ductile iron roll with a casting groove,

HSS Roll High speed steel roll known as HSS roll are a kind of hot roll material with excellent performance. The application of high speed steel roll is an important component of the development of modern steel rolling production and another major technological change in the development of the steel industry. High speed steel rollers have higher hardness and wear resistance than traditional rollers. The centrifugal casting high-speed steel rollers have been widely used in the production of hot-rolled narrow strip steel, sheet steel, section steel, rebar, spring flat steel, high-speed wire and other fields. They are not only used for working rolls, but also for the back-up rolls.
