            TD系列斗式提升機(jī)主要特點(diǎn)

            1.提升范圍廣,這類提升機(jī)對(duì)物料的種類、特性要求少,不但能提升一般粉狀、小顆粒狀物料,而且可提升磨琢性較大的物料.密封性好,環(huán)境污染少。
            2. 驅(qū)動(dòng)功率小,采用流入式喂料、誘導(dǎo)式卸料、大容量的料斗密集型布置.在物料提升時(shí)幾乎無回料和挖料現(xiàn)象,因此無效功率少。
            3.使用壽命長(zhǎng),提升機(jī)的喂料采取流入式,無需用斗挖料,材料之間很少發(fā)生擠壓和碰撞現(xiàn)象。本機(jī)在設(shè)計(jì)時(shí)保證物料在喂料、卸料時(shí)少有撒落,減少了機(jī)械磨損。
            4. 運(yùn)行可靠性好,先進(jìn)的設(shè)計(jì)原理和加工方法,保證了整機(jī)運(yùn)行的可靠性,無故障時(shí)間超過2萬(wàn)小時(shí)。提升高度高.提升機(jī)運(yùn)行平穩(wěn),因此可達(dá)到較高的提升高度。

            Features
            1. Ascension is wide, this kind of elevator less kinds, characteristics of the material requirements, not only can improve the general powder, small granular materials, and can improve grinding cut larger material. Good sealing, less environmental pollution.
            2. Driving power is small, use of feeding, induction of inflow discharge, large capacity of hopper intensive layout. In material ascends almost no back and dig material phenomenon, therefore less reactive power.
            3. The service life is long, hoist feed take into the type, without using bucket digging of material, the material between the extrusion and collision occur rarely.The machine when the design to ensure material few scattered when feeding, discharging, reduce the mechanical wear and tear.
            4. Good reliability, advanced design principle and processing method, ensure the reliability of the machine running, trouble-free time more than 20000 hours.High hoisting height. Hoist running smoothly, thus can achieve high hoisting height.
