Release date: 2023-09-02

Monazite, also known as ceric phosphate ore, is an important rare earth resource, which can be used to produce mixed rare earth chloride, comprehensive recovery of sodium diuranate, thorium nitrate and other products. Monazite rare earth concentrate needs to be decomposed before it can be applied to the downstream market. At present, the decomposition of monazite adopts mechanical decomposition method, that is, the monazite is ground into powder. So, what kind of mill is used to grind monazite into powder? Guilin Hongcheng, as a manufacturer of rare earth grinding mills, will analyze and answer for you today.

The principle of grinding monazite into powder is to mix substances that decompose monazite (such as CaO, CaCl2, NaOH, etc.) with monazite in a rare earth mill. During the grinding process, monazite and decomposer powder have undergone repeated crushing and welding processes, and decomposition reactions have occurred on the welding surface while this process is in progress. The process of grinding monazite into powder mainly adopts dry grinding method, and the grinding of monazite into powder generally adopts equipment such as vertical grinding mill and ring roller mill.

Recently, a monazite production enterprise purchased a ring roller mill produced by Guilin Hongcheng for the project of grinding monazite into powder. Due to the alkali decomposition reaction of monazite, when the particle size of monazite powder is not greater than 325 mesh, not only the reaction speed is fast, but also the conversion rate of monazite can be as high as 98%. The efficiency is high, and the particle size of the powder is small and uniform, which is conducive to improving the reaction efficiency and conversion rate of the alkali decomposition reaction of monazite.

The process of grinding monazite into powder is as follows: using a permanent magnetic concentrator to beneficiate the monazite ore associated with zircon sand to obtain a monazite concentrate with a particle size of 80-100 mesh; pass the magnetically separated monazite concentrate through negative pressure air Sent to ultra-fine ring roller milling equipment for grinding to obtain ultra-fine monazite powder with a fineness of 350 mesh to 450 mesh; the ultrafine monazite powder is mixed with sodium hydroxide: ultrafine monazite powder is 0.55:1-1.5 The mass ratio is sent to the reaction kettle containing the recovered lye by negative pressure wind for pyrolysis to obtain monazite liquid. The advantages of using Hongcheng HCH ultra-fine ring roller mill for grinding monazite into powder in this enterprise are: the PLC intelligent automatic control of the whole process of beneficiation and grinding, the equipment is sealed and dust-free, and the recovery rate of monazite is high.

HCH ultra-fine ring roller grinding equipment grinds to improve the fineness of monazite ore, and the grinding ring is made of special wear-resistant steel. Under the working conditions of impact resistance, extrusion resistance and crush resistance, the particles are uniform and fine, and the fineness of monazite particles can be adjusted arbitrarily between 350 mesh and 450 mesh. Automatic metering, mixing, conveying, supporting 7.5kw pulse dust removal equipment, fully automatic and fully sealed production process, eliminating dust pollution, reducing noise, energy saving and environmental protection.
