Application of lithium carbonate project in Jiangxi double shaft mixer

Introduction of double shaft mixer equipment:

Double-shaft mixer is mainly used for mixing, humidifying and stirring powder materials and small particle materials. The material enters the tank body from the feeding port, and the acid adding device is installed behind the feeding port of the tank body. Two rotating shafts with stirring blades rotate synchronously, pushing the material to the discharging port continuously and evenly, thus completing the mixing, stirring and conveying of the material.

Structure composition and characteristics of double shaft mixer:

The equipment is mainly composed of driving device, coupling, tank assembly, spray acid adding device, acid mist cover, driving shaft assembly, driven shaft assembly, integral frame, gear cover Assembly, shield and other components. The frame is of the whole structure. After the welding is completed, all installation surfaces are processed as a whole with high precision of processing and installation; The joint of the main shaft and the tank body is sealed with stuffing type, which is reliable, with light wear of the shaft and reliable operation; The spiral adopts paddle blade structure, which is stirred evenly and has small maintenance amount; The main shaft and blade are equal to the direct contact parts of materials and are directly processed by stainless; the blade is connected with the main shaft by stainless steel bolts, which is convenient for the blade to be replaced after wear; The key parts of the spray acid adding device and the tank sealing device are made of acid-resistant material to avoid corrosion to the internal structure caused by long-term use;

Equipment name: zj500×4m double shaft mixer

Transmission capacity: 25-30 t/h, variable frequency speed regulation

Blade Rotary diameter: 500mm

Project overview: this equipment belongs to the lithium mica calcination process transformation project of Jiangxi lithium carbonate project. The mixing material is weak acid as a whole, regular the material and structure of the double shaft cannot meet the technological requirements. By changing the material of the main shaft and the blade into stainless steel, and changing the installation structure of the blade at the same time, after strict calculation and verification, the equipment is successfully modified at one time, the on-site operation is stable, and the production capacity.
