Title:
SYSTEM FOR PRODUCTION OF SOLID MODIFIED SULFUR PRODUCTS
Document Type and Number:
WIPO Patent Application WO/2006/121166
Kind Code:
A1
Abstract:
The system of the invention is equipped with a modified sulfur production tank (3) wherein molten sulfur from a molten sulfur tank (1) is mixed with a sulfur modifier from a sulfur modifier tank (2) to produce a modified sulfur, while the contents held therein are heated to a prescribed temperature or above; a modified sulfur intermediate material tank (5) wherein the modified sulfur from the tank (3) is mixed with a fine aggregate from a fine aggregate hot bin (4) to form a modified sulfur intermediate material, while the contents held therein is heated to a prescribed temperature or above; a kneader (7) wherein the modified sulfur intermediate material from the tank (5) and a coarse aggregate from a coarse aggregate hot bin (6) are kneaded together, while the kneaded material held therein is heated to a prescribed temperature or above; and a forming unit (8) wherein the kneaded material from the kneader (7) is stored and heated to a prescribed temperature or above, while the kneaded material is metered, poured to a mold (36), and solidified therein. The system makes it possible to give solid modified sulfur products which can be stored as nondangerous (unignitable or flame-retardant) substance and are easy of transportation.
