Abstract

The invention discloses a system for improving stir-frying stability. The system comprises a primary stir-frying area, a secondary stir-frying area and a cooked material collecting area. The primary frying area comprises a stock bin (01), a belt weigher (02) connected with the stock bin (01) and a hammer type beater (03) connected with the belt weigher (02). The secondary frying area comprises anelectric dust collector (07) connected with the hammer type beater (03) of the primary stir-frying area, a zipper machine (08) connected with the electric dust collector (07), and a calcining furnace(09) connected with the zipper machine (08). The cooked material collecting area comprises an impurity screening system connected with the calcining furnace (09), a ball mill (13) connected with the impurity screening system and a cooked material collecting bin (15). According to the system for improving the stir-frying stability, one-step high-temperature quick calcination is changed into a two-step low-temperature slow calcination mode, the calcination temperature is about 550 DEG C and is reduced by about 300 DEG C compared with a one-step method, and the probability of over-calcination orunder-calcination of clinker is close to zero.

Description

technical field [0001] The invention relates to the technical field of gypsum production, in particular to a frying system for frying gypsum clinker to improve the stability of the gypsum clinker. Background technique [0002] Gypsum stone or industrial by-product gypsum exists in the form of calcium sulfate dihydrate. There are two crystal waters in its molecular formula. Only when one semi-crystal water is removed to form calcium sulfate hemihydrate can it have gelling properties. The process of removing crystal water is Calcined for gypsum. [0003] At present, one-step calcination is mainly used in the production of gypsum, but the gypsum clinker obtained by one-step calcination of gypsum often has over-burning or under-burning, resulting in unstable three-phase distribution of clinker and uneven calcination, resulting in gypsum clinker. The water content is uneven. At the same time, one-step calcination belongs to high-temperature calcination. Part of the desulfurized ...
