How to choose the chain conveyor correctly and reasonably?

The correct selection and maintenance of the chain conveyor can give full play to the best performance of advanced equipment. Therefore, when selecting a chain conveyor, the following important parameters should be paid attention to: 1. Selection of chain conveyor model: After the chain speed is determined, the best model can be selected according to the conveying amount. Each model has a basic conveying capacity. In the model selection table also lists the maximum conveying length and power of the choice, it must be pointed out that under the same amount of transportation, the selection of slightly larger models can reduce the chain speed, thereby prolonging the service life, but the conveying amount should not be too small, such as the actual conveying amount is lower than the rated conveying capacity of the machine more than 30%, the use of the material layer will be too thin, the internal pressure is too small, resulting in idling, but increase wear. 2. Select the chain speed: the user should first choose according to the performance and state of the material being transported (such as grindability, material temperature, material particle size) and other factors. The optimal chain speed for conveying raw cement clinker and finished powder. 3. Select the inlet and outlet: the size of each inlet, the user needs to select, in the selection must be noted. A. For materials with poor fluidity or high humidity, it is generally not appropriate to use the upper inlet to avoid poor feeding, and the inlets on both sides should be used as much as possible. B. When the first inlet is close to the tail shaft (when the minimum distance cannot be guaranteed), it is generally not appropriate to use the upper time mouth. C. When the first inlet is close to the tail shaft (when the minimum distance cannot be proved), it is generally not appropriate to use the upper time mouth. D. The machine can use multiple inlet ports and multiple outlets, in addition to providing outlets with gates according to user needs. E. When the two chain conveyors are cross-connected up and down, the lower chain conveyor should use both sides of the inlet as much as possible. 4. Reduction rati

A belt conveyor is a mechanical tool that uses friction to drive materials in a continuous manner. It is generally composed of various parts such as frame, conveyor belt, roller, roller, elastic device, transmission device and so on. It completes a conveying process that transports the material from the initial feeding point to the final discharge point. It is possible to transport bulk materials or to transport complete items. Not only can the transportation of materials be carried out, but also the requirements of the process in the production process of various industrial enterprises can be cooperated with the assembly line work. Belt conveyors are generally composed of two end rollers and a closed belt on which they are tightly covered. The roller that drives the conveyor belt is called the driving roller; there is also a roller used to change the direction of the belt movement, which is called the reversed roller. The drive drum is driven by an electric motor through a reducer, and the conveyor belt is dragged by the friction between the drive drum and the conveyor belt. Belt conveyor is often used for coal transportation, can also be said to be the ideal efficient continuous transportation equipment of coal mines, different from other equipment, with long transmission distance, large transportation volume, can be continuous transportation and other advantages, in the process of operation is very stable, can be automated and centralized control, especially suitable for high-yield and efficient mines, belt conveyor has become the key equipment of coal mining mechatronics technology and equipment. The main feature of the belt conveyor is that the fuselage can be easily retracted, with a storage belt warehouse, the tail can be extended or shortened with the needs of the coal mining working surface, the structure is compact, and it does not need a strong foundation, which is laid directly on the roadway floor, light and dexterous, and it is also very convenient to load and unload. When the conveying capacity and distance are large, it can be equipped with an intermediate drive device to complete the requirements. According to different conveying requirements, it can be conveyed
