To ensure high productivity of grain cultivation, it is necessary to use energy-efficient equipment at all stages of the technological process and to have high-quality seed material. After growing the crop, it must be processed and delivered to the consumer. The quality of the material, in particular the seed, depends on many factors, one of the main ones being its injury.

In order to solve this problem, it is necessary to determine the sources of injuries, their causes, as well as to develop and implement organizational, technological and technical measures to eliminate them. Most of the consequences of grain injury are hidden and do not appear immediately. most occurs during its contact with the metal working bodies of machines. 

Operations aimed at preliminary processing and subsequent storage of grain are important stages of the entire technological process of post-harvest processing, because the suitability of grain for storage and, accordingly, the supply of consumers with seed and food material depend on them.

The technological scheme, in accordance with which the grain will be brought to a state that will ensure its quality storage, depends on many factors, such as natural and climatic conditions, the provision of the farm with appropriate means, etc.

All technological operations are accompanied by the movement of grain by various means of transport, sometimes these means perform the role of cleaning machines. In addition, it is important to use grain throwers, which, in addition to transport functions, partially carry out the separation and drying of grain.

The scale of seed damage depends on the design and operational parameters of the machine, the state of the seed mass, as well as the characteristics of the grain variety. Belt grain throwers without appropriate design are only suitable for processing feed grain. As for work with seed material, they need to be modernized to eliminate existing shortcomings.
