回转筛透筛率高，特别适应粘湿物料的筛分，筛孔不易堵塞。因此它广泛应用于电力、矿山、冶金、建材、化工等行业的原煤、沙子、碎石等物料的筛分和分级。 SH型回转筛为复混肥专用筛，可四级筛分，其中成品区有两个区段。SH型回转筛自带料仓，料仓下部有扇形闸门，粗料段有溜槽可以将粗料直接送到运输机械，便于工艺布置，用户如要求成品区只设一个区段，即三级回转筛，应在订货时说明。
Rotary screen through screening rate is high, especially to adapt to the wet material screening, the mesh is not easy to jam.So it is widely used in electric power, mining, metallurgy, building material, chemical industries such as coal, sand, gravel and other material screening and grading.SH type rotary screen for special sieve mixed fertilizer, can be 4 class screening, the finished product area, there are two sections.SH type rotary screen with bin, bin bottom fan gate, coarse material section has chute coarse material can be directly sent to the transport machinery, easy to process arrangement, such as user demands of finished area only a section, the triple rotary screen, should be when ordering.
SH型系列回转筛工作原理:
SH系列回转筛主要有电机、减速机、滚筒装置、机架等机构组成。滚筒装置倾斜布置。电动机经减速机,与滚筒机构连接在一起，驱动滚筒机构绕其轴线转动。当物料进入滚筒装置后，由于滚筒装置的倾角与转动，使合格物料（筛下产品）经滚筒外圆的筛网排出，不合格物料（筛上产品）经滚筒末端排出。SH型系列回转筛滚筒装置通过机体密封盖密封，从而保证设备在工作过程中，有效防止粉尘外逸，杜绝粉尘污染。更换筛网时，只需将机体密封盖打开即可更换，操作方便。
Working principles
SH series rotary screen mainly include motor, reducer, drum gear, rack, etc.Tilt cylinder device layout.Motor through reducer, together with the drum of institutions, drive roller institutions around the axis of rotation.When the materials enter the cylinder device, due to the Angle and the rotation of drum unit, the qualified materials (undersize) by cylindrical drum sieve, unqualified material (product) on the screen by the end of the cylinder.SH series rotary screen roller device through the body cover gasket sealing, to ensure that equipment in the process of work, effectively prevent the dust from outside, prevent dust pollution.Replacing sieve, need to open the body sealing cover can be replaced, easy to operate.
SH系列回转筛产品特点:
1.物料适应性广：回转筛广泛应用于各类物料筛分，无论是劣质煤、煤泥，还是煤烟以及其它类物料，都能顺利筛分。
2.进料方式简单多样：回转筛进料口可根据现场实际设计，无论是皮带、漏斗或其它进料方式，不用采取特殊措施，都可以顺畅进料
3.筛分效率高：设备设有梳型清筛机构，在筛分过程中，不管进入筛分筒的物料多脏、多杂都可以筛分，从而提高了设备的筛分效率
4.筛分量大、易于大型化：在相同尺寸下，圆面积比其它型状的面积都大，因此其筛分有效面积就大，使物料能充分接触筛网，因而单位时间内筛分量就大。又因其结构简单，布置方便，技术新颖而成熟等特点，极易大型化。
5.自身能耗小： 回转筛电机功率小，是其它筛型的二分之一到三分之一，处理相同量物料运行时间仅为其它筛型的二分之一，因此能耗低。
6.工作环境好：整个筛分筒可以用密封隔离罩密封，彻底清除了筛分循环过程中的粉尘飞扬、块状分溅等现象，避免了对工作环境的污染。
7.设备噪音低：回转筛在运行中，由于回转速度小，并且有密封隔离罩与外界隔离，使噪声无法传递到外部，从而降低了设备噪音。
8.使用寿命长，维修量小：回转筛是由若干个圆环状网组成，其总筛分面积远远大于其它筛型的筛分面积，再加上筛分效率高，设备运行时间短，故而使用寿命较长 ，易损件少、维护量小。
9.检修方便：设备密封隔离上罩可以拆开，拆开后不影响机器正常运行，并且使得检修非常方便。
Characteristic
1. Wide adaptability of material: rotary screen is widely used in various types of materials screening, whether it is inferior coal, coal slurry, or soot, and other materials, can be smoothly screening.
2. A variety of feeding way is simple: rotary screen feed port according to the actual design, whether belt, or other means of feeding funnel, don't have to take special measures, can be smooth feeding
3. High screening efficiency: the equipment is equipped with the comb type screen, in the process of screening, no matter how dirty into the sieve tube material, more complex can sieve, thus improve the screening efficiency of the equipment
4. Large quantities of screen, easy to large-scale: under the same size, the area is larger than the area of the other shape, therefore its screening effective area is big, the material can be fully contact screen, thus sieve weight per unit time is large.And because of its simple structure, convenient layout, characteristics of new technology and mature, easy to large-scale.
5. Small energy consumption, small rotary screen motor power, is the other half of the screen type to a third, dealing with the same amount of material running time is only for the other half of the screen type, low energy consumption.
6. Good work environment: the sieve tube can use sealing isolation cover sealing, thoroughly remove the screening cycle process of dust flying and massive splash phenomena, such as to avoid the pollution to the working environment.
7. Equipment noise low: in the operation of the rotary screen in, due to the rotation speed is small, and has the cover sealing isolation isolation with the outside world, make noise cannot pass to the external, which reduces the noise equipment.
8. Long life, small amount of maintenance: rotary screen is composed of a number of circular ring network, its total screening area is greater than that of other type sieve sieve area, plus high screening efficiency, equipment operation time is short, so service life is longer, less wearing parts, small amount of maintenance.
9. Easy maintenance: equipment cover sealing isolation can open it, open after will not affect the normal operation of the machine, and make the maintenance is very convenient.
