Roller conveyor operates via motor gearbox to activate sprocket steady conveys materials. It composed by roller, frame, support leg and drive units.
Working Principle and Structure
Roller conveyor (or called spiral pipe conveyor) is a new type of conveying equipment, used for conveying the material by horizontal. Its working principle is in the cylinder roller body is welded with continuous spiral blades, after the material is lifted by the effecting from the rotation of rollers and friction force between material and rollers, and under the action of material?s gravity, the material is scroll down along the screw blade surface and doing the axial movement. When the material is entering from the inlet, means the material import to the main body by the screw in the inlet, with the roller?s rotation, then to be conveyed to the outlet.
Roller conveyor is composing of the roller, gyro wheel, riding wheel, inlet &outlet, gear reducer motor. Not only for the ends of roller have inlet &outlet, can be set up couple inlet or outlet in the central roller also, there are sealing device for each inlet or outlet, to prevent the material leakage. In order to prevent the dust will overflow caused by the pressure when to add the material, can be set up the inlet seal or vacuuming in the inlet according to requirement.
Central inlet device is composing of Up and down fixed shell and curved blade feed plate which is installed on the roller and rotating along with the roller. Since the material comes from the shell side inlet, imported the material to the roller by rotating feed plate and conveying the material. The end of the central inlet is equipped with the valve, input quantity to be controlled. Due to the guide vane of the inlet is made to arc-shaped, so when the inlet valve of the central inlet is closed and stop to feed, the material cannot be overflow from the inlet, what is conveying in the roller, thus the central inlet only can be the inlet and cannot be the outlet.
Central outlet device, not only including the fixed shell, and there are two relative arc-shaped door on the roller, which rotating along with roller. There is a rotating shaft leads from the door, it?s for operation on the outside of the shell. And there is a fixed positioning device, can be selected outlet for discharging optionally.
Conveying length of roller conveyor (means the center distance between inlet and outlet of both ends.) Usually, it?s in 3-40m, each 0.5m cab be selected optionally, the complete machine is comprised of piecewise rollers. Gyro wheel was set up between rollers and connecting flange, bottom of gyro wheel there is the riding wheel for bearing the rotation, and to be the drive by gear reducer motor on the end (end of inlet or outlet)
The riding wheel is composed of base, frame, wheel shaft, the wheel and rolling bearing. After heat treatment, the surface hardness of wheel excircle is high and improves the wear resistance. There is oil groove under the frame, it?s for lubricating the wheel, when is conveying the materials in high temperature, the rolling bearing should be adopted the high temperature lubricating grease, such as molybdenum disulphide grease. On both ends of the base, there installed the adjusting bolt, as moving the wheel for adjust the up and down or left and right deviation of the roller. When the conveying material with high temperature or roller is long, it?s must be used the wheel with an extended pressure surface, so that can be meet the request of bigger telescopic scope.
Range of Application
The roller conveyor has the following characteristics:
1)Compact structure, easy operation.?
2)Good leakproofness due to the conveying is closed, thus can avoid dust pollution, to improve the working condition.?
3)Can be conveying material in high temperature, because there is no bearing with oil lubrication and characteristics of roller is can be Axial expansing.?
4)During the roller is running process, due to its rotating is on the wheel which is installed rolling bearing, in the meantime the material is move forward with drop condition by its own weight, and the spirochete in the roller is continuous blade, no hinder of intermediate bearing, thus resistance is small during conveying process. Power consumption is about 50% less than other type of conveyor, it?s a good energy saving transportation equipment.?
5)Due to the material is rolling along with the material surface during conveying, there is less sliding happened with roller and inner spiral blade, thus it?s less abrasion to roller and spiral blade, long using time and low maintenance cost.?
6)Can be realize variety process as conveying, stirring, mixing etc. in the meanwhile.?
7)Can be more feeding and more output.?
8)When feeding at the end, it can adapt to the uneven feeding requirements, and there will not jam happened if feeding material is too much.
Due to the characteristics of roller conveyor as above mentioned, therefore, there is a wide range for adapt conveyed material, not only can transport powder, granular, block and fluid materials, also has good adaptability for high temperature, uneven feeding, and requirement of shatterproof, pollution prevention and more feeding and more output. So the roller conveyor is widely used in building material, chemical, mining and metallurgy, electric power, food and other industrial sectors. Practice has proved that it has obtained good effect in transport of material as cement clinker, dried limestone, rock phosphate, ilmenite powder, coal, slag etc.
The roller conveyor is not adapt to transport the wet powder with stickiness or high moisture and difficult to flow, because the roller conveyor is depend on the material will move forward with drop condition by its own weight. The particle size of material comes from the inlet in end cannot bigger than 1/4 screw diameter; The particle size of material comes from the middle inlet cannot bigger than 30mm; In order to avoid the roller will be deformation by high temperature, have to control the temperature of feeding material must be controlled under 300?.
Mesh Conveyor has two series: Modular plastic belt conveyor and Metal mesh conveyor. The modular plastic belt conveyor can be assembling into any length and width according to users’ needs, it is similar to Modular construction, which is capable for connecting and reconnect various modules.
The belt conveyor is continuity conveying device driven by friction driver. It composed by frame, carrier roller and transmission device etc.
Types and application range
Belt conveyor is a transportation equipment to be widely used in sectors of chemical, coal, metallurgy, mining, building materials, electric power, light industry, food, traffic and transportation etc. it?s suitable for conveying various bulk material such as granular, powder which loose density is in 0.5-2.5t/m3,and pieces of goods also.
Selection of belt speed
1) Should be selected a higher belt speed when it?s a bigger conveying capacity and wider conveyor belt.?
2) Should be selected a higher belt speed when it?s a longer horizontal conveyor; when the conveyor angle is larger, transmission distance is shorter, then the belt speed should be lower.?
3) If the material is easy to scroll, big granularity, strong rubbed, or easy to dust and high demand for environmental health conditions, then to select the lower belt speed will be better.?
4) Commonly, if used in feeding or conveying the material with large dust, the belt speed can used 0.8-1m/s, or decision according the characteristics of material and process requirement.?
5) The belt speed should not be more than 1.25m/s. When the weighing and burdening is by manpower.?
6) The belt speed should not be more than 2.0m/s when the plow discharger is used.?
7) The belt speed should not be more than 2.5m/s when the discharging car is used, and when it?s conveying the material after fine grinding or small pieces, the belt speed can be 3.15 m/s.?
8)The belt speed should be commensurate with the requirements of automatic quantities? scale when there is MWBL.?
9)Commonly, the belt speed should be less than1.25m/s.when it?s conveying pieces of goods?
Selection of conveyor belt
The belt used in the belt conveyor there is rubber belt, plastic belt, steel belt, metal mesh belt and so on, the commonly one is rubber belt. There are many kinds of rubber belt such as cotton core, synthetic fiber core, steel cable core etc. There is layer core and full core difference for the plastic conveyor. The various core materials and different cover gum can be made up to various kinds of smooth or patterned conveyor belt.
Vertical Srew Conveyor
Conveying principle and characteristics
Vertical screw conveyor(also called vertical spiral conveyor or auger), the structure principle is as follows: In picture 15-21, the feeding of the vertical screw conveyor is for mandatory feeding, when its running, screw 2,4 to be doing the rotary motion. The conveying material will be entering from horizontal feeding inlet 1, goes through the running horizontal feeding screw 2 and to be conveyed to the vertical part, then to be push up to the outlet 6 for discharge by vertical screw 4.In picture 15-22, the feeding of vertical screw conveyor is for Auto-flow type, when the conveyor is working, screw 2 to be doing rotary motion, the material to be entered from inlet 1, and to be push up to the outlet 4 for discharge by vertical screw 2.
When the vertical screw doing the rotary with angular velocity ?, the object m as the mass upon surface of the screw blade will be follow the rotation. Meanwhile there is the centrifugal force on objects F=mr?2, the object under the action of centrifugal force F, there will be three possibilities as below:
1)When centrifugal force is less than the friction between the screw surface and object, the object will always be rotary along with the screw; will not close up the shell, thus impossible to be push up.?
2)When centrifugal force is more than the friction between the screw surface and object, the object will close up the shell. But when the friction between object and shell is not enough to overcome the friction between object and surface of screw blade, and cannot overcome the component force, which is caused by its own weight and down along the surface of screw, then object will always be rotary along with the screw too, and impossible to be push up also;?
3)When the friction between object and shell is greater than the friction between object and surface of screw, and the component force caused by its own weight and down along the surface of screw too, object will slide with screw surface and rising along the opposite direction of the spiral trajectory, means that object to be push up by vertical part of screw, thus to achieve the vertical transportation.
Therefore the revolving speed of vertical screw shaft must be higher than a value which is the objects can be push up (called critical speed), otherwise, the conveying operation cannot proceed, it?s the main characteristic of the vertical screw conveyor.
Feeding of vertical screw conveyor must keep the necessary pressure, when a lesser difference for feeding, vertical screw conveyor is all equipped with horizontal screw feeding. Generally, the horizontal feeding screw and the vertical screw will be combining to be 1 completed conveyor, the diameter of the horizontal feeding screw is same as the vertical screw, and the RPM of horizontal screw is lower than the vertical screw.
The advantage of the vertical screw conveyor is: Simple structure, Small spatial location, Easy for airtight transportation, cost is lower. Its disadvantages are: small capacity, conveying height is lower (Normally less than 8M).
1)Vertical screw conveyor is suitable for conveying various powdery and granular materials, such as carbon black, flour, cement, sand, grain and renewable rubber powder, etc.
2)Vertical screw conveyor is not suitable for conveying the materials what is easy to perishable or high viscosity, agglomerate ,corrosive.
3)Range of working temperature is within -20~50, temperature of the conveying material should be lower than 200?.
