Abstract

The invention provides an automatic control system for lithium carbonate production, comprising a mineral analyzer, a central control server, a roasting controller, a roasting device, a particle sizeanalyzer, a grinding controller, a grinding device, a first flow meter, a second flow meter and an electromagnetic valve controller. The embodiment of the invention can achieve automatic setting of the working and temperature of the roasting device, automatic setting of the grinding time of the grinding device, and automatic control of the addition of concentrated sulfuric acid in the acidification process during preparation of beta-spodumene concentrate with natural spodumene and the grinding and sulfuric acid acidification process, the operation is simple and has no error, and requirements for automatic lithium carbonate production of people are met.

Description

technical field [0001] The invention belongs to the technical field of chemical production, and more specifically relates to a lithium carbonate production automation control system. Background technique [0002] At present, the production methods of industrial-grade lithium carbonate are divided into two categories due to different raw materials: lithium extraction from ore and lithium extraction from salt lake brine. Although lithium extraction from salt lake brine is currently the mainstream production method in the world, because my country is extremely rich in lithium-containing ores, its reserves rank third in the world, and extraction of lithium from ores is still the main production method for lithium carbonate in my country. [0003] At present, the existing spodumene lithium extraction method for lithium carbonate production is the most widely used sulfuric acid method. The production of lithium carbonate by sulfuric acid method needs to prepare natural spodumene ...
