GYPSUM HEATING METHOD, GYPSUM HEATING DEVICE AND PROCESS OF MANUFACTURE OF GYPSUM
PROBLEM TO BE SOLVED: To provide a gypsum heating method, gypsum heating device and process of manufacture of gypsum in which its drying and calcination capability is improved, a processing large amount of gypsum is facilitated and its miniaturization can be attained.SOLUTION: This invention relates to a method for heating gypsum by using a heating device in which a rotary cylinder is rotated in such a way that a critical speed ratio α defined by equation 1 and equation 2 may become less than 15 to 70% to heat gypsum. Equation 1: Vc=2.21D, equation 2: α=V/Vc*100, where Vc is a critical speed of the rotary cylinder, D is an inner diameter [m] of the rotary cylinder, α is a critical speed ratio [%] of the rotary cylinder and V is a rotating speed [m/s] of the rotary cylinder.SELECTED DRAWING: Figure 14
【課題】乾燥焼成能力を向上させて、石膏の大量処理を容易にするとともに、小型化を可能にする石膏の加熱方法、石膏の加熱装置および石膏の製造方法を提供すること。【解決手段】加熱装置を用いて、石膏を加熱する方法であって、式１、式２で定められる臨界速度比αが１５〜７０％未満となるように、回転筒を回転して、石膏を加熱する。Ｖｃ＝２．２１Ｄ1/2・・・式１α＝Ｖ／Ｖｃ・１００ ・・・式２ここに、Ｖｃは回転筒の臨界速度（ｍ／ｓ）、Ｄは回転筒の内径（ｍ）、αは回転筒の臨界速度比（％）、Ｖは回転筒の回転速度（ｍ／ｓ）である。【選択図】図１４
