Description

Pierwszenstwo: Zgloszenie ogloszono: 30.05.1973 Opis patentowy opublikowano: 12.05.19752 78034 Zgodnie ze schematem ukladu urzadzen, przykladowo sposób przygotowania gliny wedlug wynalazku odbywa sie nastepujaco: gline po rozdrobnieniu na strugaczu S wzglednie walcach nozowych WN lub gniotowniku sitowym GS, podaje sie do suszarni obrotowej SO, skad ziarna gliny o zadanej granulacji i stopniu wysuszenia skierowywuje sie do mlynów pretowych MP. Ziarna gliny o granulacji wiekszej od wymaganej, odsiane na przesiewaczu P, poddaje sie rozdrobnieniu na walcach gladkich WG, i wprowadza sie do ponownego suszenia do suszarni obrotowej SO. Cykl obejmujacy rozdrabnianie gliny po pierwszym suszeniu oraz wtórne suszenie trwa do czasu, az wszystkie ziarna uzyskuja zadana granulacje, a tym samym odpowiedni stopien suszenia.Uklad urzadzen do stosowania sposobu wedlug wynalazku, obok urzadzen wystepujacych przy realizacji znanego sposobu rozdrabniania gliny, takich jak: strugacz S, walce nozowe WN, gniotownik sitowy GS, jest dodatkowo wyposazony w przesiewacz wibracyjny P oraz walce gladkie WG, które sa umiejscowione za suszarnia obrotowa SO, a walce gladkie WG polaczone sa z zasypem suszarni obrotowej SO tworzac obieg zamkniety. PL PLPriority: The application was announced: May 30, 1973 The patent description was published: May 12, 19752 78034 According to the scheme of the arrangement of the devices, for example, the method of preparing clay according to the invention is as follows: rotary dryer SO, the composition of clay grains with a given granulation and degree of drying is directed to the MP belt mills. Clay grains with granulation larger than required, screened on the P screen, are ground on WG smooth rollers, and re-dried in the SO rotary dryer. The cycle involving grinding the clay after the first drying and secondary drying lasts until all grains achieve the desired granulation, and thus the appropriate degree of drying. The system of devices for applying the method according to the invention, in addition to the devices used in the implementation of the known method of grinding clay, such as: S, WN knife rollers, GS screen crusher, is additionally equipped with a P vibrating screen and WG smooth rollers, which are located behind the SO rotary dryer, and the WG smooth rollers are connected with the SO rotary dryer charge forming a closed circuit.

Claims

1. Claims 1. The method of preparing plastic raw materials, especially clay, including grinding on a planer, knife rollers, and a sieve crusher, and first drying in a rotary dryer, characterized by the fact that raw material grains with granulation indicating insufficient drying from the inside, preferably grains over 40 mm, it is separated on a screen (P), preferably vibrating, is subjected to secondary grinding on smooth rolls (WG) and re-introduced to the rotary dryer (SO), this cycle repeating until the raw material grains with granulation ensuring its sufficient drying, then the raw material is crushed on a grinder (MP) and introduced into silos.

2. A system of devices for applying the method according to claim 1, comprising a planer, knife rollers or sieve grinder, and a rotary dryer and a grinder, characterized in that it is equipped with a screen (P), preferably vibrating, and smooth rollers (WG), the devices being located successively after the rotary dryer (SO ), and the smooth rollers (WG) are combined with a rotary dryer (SO), creating a closed circuit. e.g. for silosón m. and LJU L | (&) \ PL PL
