　　The features and applied range of type LS screw conveyor

　　Type LS screw conveyor is characterized by update structure, advance technology purpose, head and tail bearing outside shell. Middle hanging bearing is used rolling or sliding changeable structure. It has dust against sealing device. Outlet device is designed clean device which is characterized by low noise, strong applicability, convenient maintenance, smooth inlet and outlet arrangement.

　　应用范围

　　江苏中矿生产的螺旋输送机，广泛应用于化工、建材、粮油、饲料、食品、冶金、矿山、塑料、医药等行业;适用于水平或小于20度倾角，输送粉状、粒状和小块状物料，如水泥、煤粉、粮食、化肥、灰渣、砂子等，物料温度200度以下。

　　LS型螺旋输送机不宜输送易变质、粘性大、易结块的物料，因为这些物料在输送时会粘结帐螺旋上，并随之旋转而不向前移动或者在吊轴承处形成物料的积塞，而使螺旋机不能正常工作。

　　LS型螺旋输送机螺旋直径从200毫米到500毫米，共有五种规格，长度从4米到70米，每隔0.5米一档，选型时应符合标准公称长度，特殊需要可在选配时另行提出。

　　Application range

　　Screw conveyor is widely used in all kinds of industry department, For example: building material, electric power, chemical industry, metallurgical, coal, Al and Mg, machinery, light industry and food stuffs etc. industry. It is used to convey powder material, grain material and small lump material such as cement, coal powder, fertilizer, dust slag and sand etc. in horizontal or less than 20 degree slope. The material temperature is below 200 centigrade.

　　Screw conveyor can7 t convey transmutative easily, big clay and easily lump material. When conveying these materials, they will clay in the screw. Move toward with the rotation or block material at the position of hanging bearing and make screw conveyor not work usually.

　　The diameter of type LS screw conveyor is from 200mm to 500mm.They are five specifications which length is 4m to 70m. There will be a shift every 0.5m. When selecting, comply with standard nominal length. If it is special need, mark it in selecting assemble part.

　　Two ways of screw conveyor accord to driving way.

　　C1 way—When the length of screw conveyor is less than 35m, use single side driving.

　　C2 way—When the length of screw conveyor is more than 35m, use double sides driving.

　　Type of middle hanging bearing for screw conveyor:

　　M1—Rolling and hanging bearing, Use type 80000 sealing bearing. There is a dust againt sealing structure. It is usually used in easy adding oil, no oil or oil pollution place. The sealing effect is good and the life of hanging bearing is long. The temperature of conveying material is less than 80 centigrade.(When placing an order, it may not be marked.)

　　M2—Sliding and hanging bearing. It is designed sealing device. It is usually used in higher temperature(over 80 or convey hydraulic material.

　　一台螺旋机通常按驱动装置、头节、若干标准中部节，选配中间节，尾节顺序组成，除头节 机壳和选配节外，各节螺旋及机壳均具有互换性，在出料端螺旋有清料装置，安装时注意位置。

　　驱动装置由一台行星摆线针轮减速电机(或JTC减速电机)或选JZQ型减速机承担，在头节前部 装有止推轴承，可承受移动物料时而产生的轴向力，头节机壳内设吊轴承及底座，每一中间节安 有一只吊轴承用以支撑螺旋轴，吊轴承内装有向心球轴承(或整体滑动轴承)，在尾节后部装有滚动(滑动)轴承用以支撑螺旋轴和补充螺旋长度的误差，安装时应从头部开始，顺序进行。

　　Screw conveyor is made up of driving device, head node, many standard middle parts, selection middle part and tail part. Except screw and machine shell，screws and shell can be changeable. Outlet screw has clean device and note the position when installation.

　　Driving device is burdened with planet cycloid needle wheel reducer(or JTC reduced motor) or select JZQ reducer. There is a thrust bearing in front of head node and can bear shaft power because of moving material. Head shell is arranged hanging bearing and pedestal. Every middle node is installed a hanging bearing to support screw shaft. Hanging bearing is installed centripetal ball bearing(or whole sliding bearing),There is rolling(sliding)bearing to support screw shaft and make up of the error of screw length at the back of tail node. When installation, start from head in turn.

　　Note to arrange pedestal and outlet which can; t be on the connection of shell flange. Inlet E1 should not be arranged on the top of hanging bearing. If it can; t comply with the regulation, the customer should provide general drawing of screw conveyor.

　　2、进出料口

　　螺旋机进料口、卸料口由用户现场开，一般应从尾部进料，端部出料，也可从端部进料、由尾 部出料;若需从中部加料，两端卸料，或从两端加料，中部卸料、订货时需来简图。

　　(1)进料口

　　进料口的结构表示如下图，进料口是用以连接螺旋机和进料漏斗的部件，其由盖扣夹紧在机盖 上，也可用焊接的方法与机盖相联，装置进料口时应在所装的机盖上按进料口内孔尺寸开孔。

　　2. Inlet and Outlet

　　The structure of inlet is as the following drawing. Inlet is to connect screw conveyor and inlet funnel. The cover is clamped on the machine cover. Or connect with welding. Open the hole according to inlet inside hole on machine cover when installing inlet.

　　在总体布置时还应注意，不要使机座和出料口布置在机壳接头的法兰处，进料口也不应布置 在吊轴承的上方，如果因为开出料口影响机座的安排而不能遵循本原则时，使用单位应绘制螺旋机总图。
