Reliable Conveyor Equipment Manufacturers China
Tongxiang is one of the conveyor equipment manufacturers china.
1.Belt conveyor, as the carrier of bulk material, is widely used in the field of bulk material transportation because of its stability, large transportation, long transport distance, safe and reliable logistics, strong environmental adaptability, low production equipment and delivery cost. For a long time, the transmission mechanism, running characteristics and production skills of the belt conveyor have been discussed, but the cost and cost of its planning and production are seldom discussed. With the rapid development of the enterprise production to the modern scale, the strong belt conveyor with long transport distance is used throughout the selection, and the production and operation cost of the conveyor is also being paid more and more attention. How to reduce the cost of conveyor production and operation is the key to carry out the application of large belt conveyor. In this paper, from the analysis of the factors that affect the skill economic function of the belt conveyor, this paper discusses the principle of reasonably determining the speed of the belt, and puts forward an effective way to reduce the production and operation cost of the conveyor.
The main factors that affect the production and operation of the conveyor are bandwidth, strength, drive equipment, belt conveyor idler roller, roller and various supports under the condition of the transportation and production skills. The difference of the driving power varies between these factors, and all the factors are closely linked with speed. In the belt conveyor planning, only the parameters that can be determined unilaterally is the belt speed, the speed of the determination is reasonable, directly affect the skill and economic function of the conveyor.
(1) the link between speed and bandwidth of belt conveyor
The calculation indicates that the price of the conveyor belt is about 40% of the total investment in the belt conveyor, so reducing the bandwidth is very advantageous for the investment in the down conveyor equipment.
(2) the relationship between belt conveyor belt speed and strength
The higher the belt speed is, the smaller the conveyor's running resistance is, and the maximum tension of the conveyor belt decreases, so the strength of the conveyor belt also decreases. All the supporting standards set up are reduced, and the economic functions have been significantly improved.
(3) the connection between belt conveyor belt speed and driving equipment
Because of the speed progress, the running resistance of the conveyor belt is reduced, so the output torque and the speed reduction ratio of the reducer are decreased, the mechanical input power and the heat transmission power of the reducer are progressed relatively, and the type selection standard of the reducer is reduced, and the investment of the conveying equipment is reduced.
(4) the relationship between belt conveyor belt speed and roller speed
Belt conveyor planning standard rules, roller roller application speed should not exceed 750r/min, for progressive transmission equipment reliability and service life, most belt conveyor Planning Manual recommends the roller speed should not exceed the 600r/min, so when a diameter of the roller speed beyond 600r/min, the selection of higher level other rollers, resulting in the transport equipment and operation resistance increase. Nowadays, there are 6 rolls of product standard, namely, 89mm, 108mm, 133mm, 159mm, 194mm and 219mm.
(5) connection between belt conveyor belt speed and roller
With the progress of belt speed, the width and intensity of conveyor belt will be reduced, and the matching standard of drum will be reduced, which will be very beneficial for reducing investment.
Of course, the factors that affect the speed selection are not only the transport volume and the transport distance, but also the material particle size, the carrier angle, the ambient wind speed, the soft start and the soft parking equipment, which have a direct influence on the selection of the belt speed. As the material is with the conveyor belt between the two rollers, the acceleration of the vertical conveyor belt and the speed of the conveyor belt will occur during the change of the material with the sag periodically. The higher the material, the greater the material acceleration. When the acceleration direction of the conveyor belt and the material is opposite, the material is ejected. When the material inertia force is greater than the weight of the self weight and the adhesive force, the material is out of the conveyor belt. The material roll phenomenon becomes more severe with the increase of the material size and the inclination angle of the carrier. When the friction between the materials is less than the wind resistance, the material will float up and cause environmental pollution. Therefore, when the wind speed is reversed with the carrier, the higher the wind speed, the speed of the belt should be reduced properly.
We discuss the important position and function of belt speed in the planning of belt conveyor. From the viewpoint of theoretical calculation, we qualitatively analyze the relationship between the belt speed and the skill economic function of belt conveyor, and get the trend of changing the speed of the skill economy with the speed of the belt. In the detailed planning, it is necessary to determine the speed of the belt in a reasonable way, and to sum up the skill and economic function of the belt conveyor, to choose the multi band speed plan, and to screen out the best economic speed.
