Iron ore of a metamorphic deposition based Anshan iron deposit. Ores plant treatment is hematite quartzite, iron minerals are mainly artifacts hematite, hematite semi artifacts; gangue minerals are quartz, followed by a hornblende, chlorite. The ore has an obvious strip-like structure, and the particle size of the impregnation is fine. The particle size of the pseudo-hematite and quartz is generally 0.02~0.2mm. The ore needs to be ground to -200 mesh 80% to separate the monomer. The flotation is carried out by anion collector weak alkaline pulp flotation method, the adjusting agent is sodium carbonate, the dosage is 1.8kg/t, and the 20% aqueous solution is added. The second-stage grinding machine has a flotation pH of 8.5~9.5 and a slurry temperature of 30~33c. The collector is a mixture of oxidized paraffin soap 390g/t and tal oil 130g/t. The process flow is shown below. The obtained flotation index is When the ore grade is 33.00%Fe, the concentrate grade is 61.20, and the recovery rate is 77.95% Fe. Compound Cone Crusher uses the best combination of crushing frequencies and eccentricity, so it can crush materials into finer.The crushing capacity of the compound cone crusher is higher compared to similar models. The machine can enhance the role of the lamination of material smashing, and effectively improve the three-dimensional shape of crushed material.

A hematite flotation process
The pneumatic and hydraulic insurance, hydraulic lock, hydraulic adjustment and hydraulic cavities cleaning make the operation easier to automate
Under normal conditions of use, the device adopts optimized design, allows trouble-free run rate more than 95%
The compound cone crusher is divided into standard type and short-head type
Short-head type compound cone crusher is conducive to the production of fine-grade materials, while standard type compound cone crusher is commonly used for medium crushing and fine crushing
Advantages of compound cone crusher
Less consumption of wearing parts, low operating cost
Laminating crushing, better shape of finished product
Hydraulic protection, hydraulic cavity clearing and high degree of automation, reducing downtime time
Thin oil for lubrication, reliable and advanced, improving the service life
A variety of crushing cavities, flexible, strong adaptability
Easy maintenance, easy operation
