產品概述
新型立式超細磨是我公司在消化吸收日本、臺灣、德國先進技術的基礎上設計的新型設備，它通過帶有旋轉、壓力的磨輥滾壓在旋轉磨盤上的物料（0-4mm）進行碾磨達到相應的細度（325—6000目）。主要技術體現在磨輥、磨盤與物料的充分接觸及分級系統的分級精度。適用于冶金、電力、化工、耐火材料、特別是非金屬如重質碳酸鈣、石頭造紙等超細粉體材料粉磨。
結構特征
具有液壓提升與液壓加載的主動式磨輥系統；給料機、磨輥、分析機采用變頻調速；主電機帶有耦合裝置。
Structure Characteristics:
Active grinding roller system with hydraulic listing and hydraulic loading; the feeder, grinding roller and the separator adopts frequency conversion adjusting speed; the main motor with coupling.
應用范圍
新型立式超細磨可用于生產粉磨和破碎的材料主要包含：方解石、石灰石、葉蠟石、重晶石、螢石、上釉、夾渣、硅灰石、高嶺土、蛭石、云母、長石、水鎂石、孢子、鉀鹽渣、石榴石、石英、鈦鐵礦、氧化鎂、氫氧化鎂、白云石等行業。
Application:
The main materials, that the new type vertical superfine grinder is applied to crush and grind mainly contain calcite, limestone, pyrophyllite, barite, fluorite, glaze, slag, wollastonite, kaolin, vermiculite, mica, feldspar, brucite, spores, potassium salt slag, garnet, quartz, ilmenite, magnesium oxide, magnesium hydroxide, dolomite, etc. And the vertical roller mill can also be used to the non-metal mining areas with the Mohs hardness of less than 7degree, such as mining metallurgy, chemical industry, electronics, medicine, food, daily chemical, agriculture, building, and so on.
工作原理
新型立式超細磨粉機系統由螺旋給料機、主機、風機、分析機、旋風收粉機、布袋收粉機、管道系統及變頻電控高配置PLC控制系統組成。其中，主機由上下機體、磨輥、磨盤、液壓加載及提升系統、氣流分配風道、主電機、減速器等部分組成。工作時，將需要粉碎的物料由主機側上方的螺旋給料機均勻、連續的送入主機內，在快速旋轉的磨盤離心力作用下，物料被拋向磨盤內側壁并被帶入磨輥與磨盤嚙合區域。通過液壓系統對磨輥加載，同時由于磨輥和磨盤的差動，物料在捏合區收到強烈剪切與擠壓而粉碎。風機產生的高壓大流量氣流通過閉路循環送風系統與已粉碎的粉體混合，形成高濃度氣流，進入主機上部的分析機進行分選，達不到細度的微粒回落到磨盤內重磨，合格微粉則隨氣流通過分析機進入旋風收粉機。在收粉機內，微粉與空氣分離后從卸料口排出即為成品。在氣流循環過程中，少量的多余氣體連同成品中的較輕的雜質被系統中的支路收塵器收集作低檔產品處理。從而形成了一個相當科學先進的工藝過程。
Working Principle:
The new type vertical superfine grinder consists of screw feeder, main unit, blower, separator, cyclone powder collector, bag powder collector, piping system, and PLC electric control system with frequency conversion and high configuration. The main unit is composed of upper and lower body, grinding roller, grinding table, hydraulic loading and hoisting system, air distributing channel, main motor, speed reducer, etc. When working, the raw materials is fed into the main unit evenly and continuously by the screw feeder on the side of the above of the main body. Under the action of the centrifugal force caused by the rapidly rotating grinding table, the materials are throw to the inside wall of the grinding table and brought to the zone of action of grinding rollers and the grinding table. Through the hydraulic loading to the grinding rollers, and the differential transformer of the grinding rollers and the grinding table, the materials are pulverized after being sheared and crimpedstrongly in the zone of action. The high pressure and big flow air currents caused by the blower will be combined with the crushed powder through the closed cycle air supply system, to form high concentration ones, and then go to the separator above the main unit to classify the powder. The unqualified fine particles will fall back to the grinding table and be grinded once again. The qualified micro-powder will go through the separator with the air currents and then go into the cyclone powder collector. In the powder collector, Themicro-powder separated with the air will be out from the discharge port to be the finished product. In the air cycle process, the little spare air together with the light impurity in the finished products will be collected by the branch dust collector to be processed as low-grade products. Then it forms a scientific and advanced process.
1運行成本低 low operation cost
磨粉效率高，電耗低，和球磨機雷蒙等其他粉磨設備相比減少了40-50%的耗電量。磨耗 小，輥套、 襯板用特殊材質，使用壽命長，減少了產品的金屬污染，降低了運行成本。可裝備有外部循環裝置， 能進一步降低電力消耗，提高產品精度。
It can high efficiently crush the materials by grinding rollers and material bed. So the power consumption system is 40-50% less than the ball mills system. And its energy-saving effect will be more prominent with the increase of the materials’humidity.
2建設費用低 low installation cost
立式磨和球磨系統相比占地面積可減少約50%，建設費用減少約70%。由于集破碎、干燥、粉磨、 分級輸送于一體，系統簡單，因此建設費用低廉。
(a) Compared with the ball mill, it has a simple crafts process and covers an small construction area, with the covering area less than 50% and construction cost less than 70%.
(b) This machine merges the crushing, drying, grinding, and classifying into a single whole. With a simple structure and compact layouts, it is suitable for the outdoor design, which ensures a low construction cost.
3運轉容易可靠 Reliable Function
裝備有自動控制裝置，可實現遠程控制，操作簡單容易。裝備有防止輥套和磨輥襯板之間直接接觸 裝置，不會出現破壞性劇烈震動。
(a) Equipped with the automatic controlling equipment, it has realized the remote control, which makes a convenient operation.
(b) It has the equipment which can prevent the direct touch between the roller sleeve and grinding plate, which can avoid the crushing intense shaking.
4維修方便 Easy to Repair
通過檢修油缸翻動轉臂，輥套、襯板在很短時間就能更換。
