Application Of Ribber Belt In Chemical Fertilizer Production

Application of Ribber Belt in Chemical Fertilizer Production
Equipment for the production of compound fertilizer, such as conveyor belts on conveyor, perimeter, bumper, drum granulator, dryer, cooler, rubber lining in the coating machine, rubber barrels in the lower part of the crusher are rubber But it is not easy to use it reasonably. Now the author in the fertilizer production of rubber products on the understanding and use described below. Belt Conveyor How to use the conveyor belt Most companies tend to use the belt conveyor material. It is characterized by simple structure, easy maintenance, low noise, large amount of delivery, not easy to plug. But if the conveyor belt selection is not good will play a role in restricting production. Poor quality conveyor belt due to the low proportion of natural rubber, the middle of the skeleton layer and the production process can not meet the requirements, resulting in belt degumming, blistering, fracture and joint strength and other issues, easily affect the production and lead to maintenance costs, 1 60m belt costs about 5000 ~ 10000 yuan.
Regular manufacturers belt operating cycle ≥ 12 months. The conveyor belt used in the production of compound fertilizer is generally divided into polyester tape (EP), nylon belt (NN), cotton belt. Polyester conveyor belt with high modulus, low shrinkage characteristics, so the conveyor belt has a very high dimensional stability, belt body elongation is very small, start smooth, suitable for long-distance transport of materials, and its own temperature characteristics. Its technical indicators: the longitudinal tensile strength of each layer ≥ 150N / mm, elongation ≤ 1.2%, wear ≤ 180mm3. In order to standardize the rational use of Ribber Belts in compound fertilizer production equipment, the characteristics and technical indexes of the rubber band used in the Ribber Belt of the belt conveyor, the dryer and the drum granulator and the rubber barrel of the crusher are expounded. , And focus on its installation, use should pay attention to the problem, in order to facilitate the extension of equipment life, reduce maintenance costs, give full play to the production capacity of the device.
 The typical Ribber Belts for automobiles are rubber-metal composite structures, which tend to exhibit large deformation bearing during the loading process. In the process of stress analysis of the rubber band, the deformation of the rubber unit is too large, the rubber unit will be a serious distortion, so that the solution of the finite element analysis can not be carried out, in order to effectively solve the problem of large deformation of rubber, for the structure and load Are analyzed by the axisymmetric characteristics, which can be reworked using a grid so that the analysis can be carried out again so that the engineering analyst can obtain the required deformation results and the overall load and displacement curves. Mesh planning is an important idea and an effective way to deal with the large deformation finite element analysis of rubber. At present, the software versions such as ANSYS and ABAQUS have the functions of grid re-marking for rubber analysis. But what is the problem?
It is not clear that, therefore, this paper will be a typical rubber components in the rubber pile of large deformation analysis as an example, the grid re-planning. The basic process is as follows: Firstly, modeling and grid processing are carried out, and a suitable load is applied. The results of the preliminary analysis are extracted by the deformation model. In this paper, Such as the success of the model after the extraction, and then the second analysis; such as the second analysis of the grid before and after the re-leveling point of the basic coincidence, then the secondary analysis is completed; such as the stiffness point of a large offset, then the initial analysis of the unit Excessive grid distortion, the need to apply a smaller In the automotive rubber band - metal composite products carried by the finite element analysis process, due to excessive deformation of the grid and produce serious grid distortion, in order to make the analysis can be carried out Go, need to re-grid grid. For rubber analysis, grid re-planning needs to be experienced: initial analysis → extraction deformation model → quadratic analysis of such one or more grid re-draw process. Experience shows that for larger deformation of the rubber band analysis, 3 to 6 times the grid re-planning is a reasonable choice.
