Product overview
Type II anhydrous phosphogypsum belongs to anhydrite binder, originally defined as a new material composed of natural or artificial anhydrite calcined at high temperature (> 600℃) and grinding together with hardening activator. Industrial by-product type II anhydrous gypsum definition: a new high-strength gypsum material composed of calcined industrial by-product gypsum with the required quality at high temperature (> 600℃) and grinding together with activator and composite material.
Product purpose: To get harmless treatment, with high strength, water resistance, light weight, high softening coefficient, strong operational performance of new building materials, for a large number of industrial by-product gypsum piled up in China to find a new process, new method of energy saving, environmental protection, large-scale production.
Production line features:
1, original waste heat utilization technology system, saving energy more than 20%; Use remote control grab feed; Reduce the pollution and unsafe factors brought by the forklift, saving 60% of the cost;
2, the use of PLC, DCS automatic control technology, DCS application of Internet, optical fiber transmission, material level temperature wireless transmission and other new technology applications, truly achieve the purpose of unattended automatic control;
3, the production line application of feeding system and self-cleaning raw material treatment system, high-temperature calcination waste heat utilization, exciter precise dosing, return material quality control system, cooling homogenization system, multi-heat source energy-saving fine control, heat source energy-saving reuse, warehouse homogenization and anti-caking technology application;
4, to solve the production of low temperature anti-corrosion method: ND steel, special corrosion resistant coating, non-metallic polytetrafluoroethylene, glass fiber reinforced plastic material application. Application of high temperature and corrosion resistant new materials special materials intelligent manufacturing equipment;
5, the whole production system negative pressure operation, new environmental protection clean ground system, full range of cleaning dust removal technology; The production line system is equipped with color positioning and ground positioning technology.
