Abstract
Computer-aided design is now the primary design tool, providing opportunities for improving project quality, allowing for in-depth analysis of the specific features of the solution. In the methodology, computer simulation applications were used. Computer simulation aims to reconstruct the course of the studied process from its mathematical model using a computer and to examine the influence of the environment (input signals) and the internal properties of the object (process parameters) on the characteristics of the object. In designing the shredder, in addition to the selection of structural features, it is also possible to perform strength and kinematic simulations, resulting in a higher quality of the target solution. The results of the simulation work presented in the paper indicate a wide range of possible applications - also in the field of food engineering and processing of polymers - eg shredder mechanisms. Particular attention has been paid to the reduction of energy consumed by the deformation of samples, eg by pre-compaction of sample before introduction to the working area of the shredder. It has been estimated that the gap between the rotating discs should be minimized. Establishing design guidelines has resulted in a number of concept designs.
Highlights
The grinding is an important step in the preparation of the product, including food processing and plastics technology
In order to improve the efficiency of crushing undertaken numerous structural modifications and mechatronic implementations. They base on the use of modern systems of measurement and control in a chopper. With such implementations we can improve parameters using CAD tools as well as monitor parallel the grinding process, energy requirements as a measure of the energy required for grinding weight of 1 kg material [7, 8]
The experimental results expand the knowledge of the shredding and provide the material to the created and the staging database for the construction and the grinding process. These data were used in an integrated expert system in order to facilitate the selection of design shredder suitable materials
Summary
The grinding is an important step in the preparation of the product, including food processing and plastics technology. In order to improve the efficiency of crushing undertaken numerous structural modifications and mechatronic implementations They base on the use of modern systems of measurement and control in a chopper. The research includes implementation of CAD tools, especially in relations with geometric relations and some simulations and mechatronic modules in laboratory/test stand in which the grinding process is employed to separate successive pieces of polymer materials as feed, by working the edge of the holes in the disks or drums [11]. The experimental results expand the knowledge of the shredding and provide the material to the created and the staging database for the construction and the grinding process These data were used in an integrated expert system in order to facilitate the selection of design shredder suitable materials.
