Ama-granule enjoloba amnyama ayizinhlayiya ezincane, eziyindilinga ezenziwe ngezinto zerabha eziphinde zasetshenziswa, ikakhulukazi ezithathwe kumathayi asetshenzisiwe. Lawa ma-granule asetshenziswa kabanzi ezimbonini ezahlukahlukene ngenxa yokuqina kwawo, ukuguquguquka kwawo, kanye nokusebenza kahle kwezindleko.

Embonini yezemidlalo, ama-granule enjoloba amnyama ayisici esibalulekile ekwakhiweni kwamasimu otshani bokwenziwa. Ahlinzeka ngesendlalelo esiqinile esithuthukisa ukumuncwa kokushaqeka kanye nezakhiwo zokuvikela utshani, kunciphisa ingozi yokulimala kwabadlali. Ngaphezu kwalokho, umbala omnyama wama-granule usiza ekumunceni ukushisa, okungathuthukisa iphuzu lokuncibilika kotshani futhi kwandise isikhathi sokuphila kwalo.

Ngaphandle kwezemidlalo, ama-granule enjoloba amnyama asetshenziswa nasekufakeni i-playground surface, ekumbozeni i-landscape, ngisho nanjengezinto zokusetshenziswa zokukhiqiza imikhiqizo emisha yenjoloba. Amandla azo okumelana nokuguga nokuguguleka azenza zibe ukukhetha okuhle ezindaweni ezinabantu abaningi, njengezindlela zokuhamba ngezinyawo kanye nezindlela zokungena.

Ngaphezu kwalokho, ukusetshenziswa kwezinhlayiya zerabha ezimnyama kunegalelo ekusimameni kwemvelo ngokunciphisa imfucuza nokukhuthaza ukuphinda kusetshenziswe amathayi asetshenzisiwe. Lokhu akugcini nje ngokulondoloza imithombo yemvelo kodwa futhi kusiza ekunciphiseni umthelela wokulahlwa kwamathayi emvelo.
