Phosphate rock is an important support for the phosphorous chemical industry. Phosphate mineral powder grinding mills are processing equipment for phosphate rock powders. Choosing a high-efficiency, intelligent, energy-saving, and environmentally friendly phosphate rock powder mill can greatly enhance the market competitiveness of phosphate rock powders and create more great value.
SBM is an excellent manufacturer of ore crushers and mills in China, specializing in the development and production of ore milling machinery. At present, for the field of non-metallic ore, there are ultrafine grinding mills, micro-pulverizers, superfine vertical roller mills, wet mills, and other industrial ore grinding equipment. It can be applied to different operating environments to meet different production needs.
Phosphate rock is a phosphate-hydrochloric acid mineral-rich in phosphorus, mainly represented by apatite. Based on phosphate rock, it can produce phosphate fertilizer, yellow phosphorus, and phosphide, phosphoric acid and phosphate, etc. The phosphorus chemical industry involves many industries, such as agriculture, medicine, national defense, metallurgy, coatings, textiles, daily chemicals, ceramics, paper, glass, ammunition, etc.
With the continuous development of technology and economy, the application of phosphorus chemical products has gradually deepened, and high-purity and high-precision products have been promoted and applied in cutting-edge science and the national defense industry. Such as electronic and electrical materials, sensor element materials, catalysts, artificial biological materials, optical materials, etc. Correspondingly, it is the higher standard requirement of phosphate rock powder grinding and purification technology.
Phosphate ore processing and production processes mainly include three processes: crushing, grinding, and beneficiation.
In the crushing process, the three-stage closed-circuit crushing is more modern and suitable for the crushing of high-hardness phosphate ore. It can complete the crushing and partial dissociation of the ore, thereby improving the subsequent grinding efficiency.
In the grinding process, the two-stage and one-closed grinding is an efficient grinding process, which can make the phosphorus ore grind more fully.
In the beneficiation process, the direct flotation process, reverse flotation, scrubbing sludge, heavy medium separation, and other process methods.
The first stage: the crushing of raw materials
Large chunks of phosphate ore are evenly sent to the jaw crusher (primary crushing) by the vibrating feeder through the silo for coarse crushing.
After the coarsely crushed phosphate rock is screened by a vibrating screen, it is sent to a single-cylinder hydraulic cone crusher (medium crushing) by a belt conveyor for medium crushing.
The medium crushed phosphate ore materials are sent to a multi-cylinder hydraulic cone crusher for fine crushing.
The second stage: milling
The crushed small phosphate ore materials are sent to the storage hopper by elevator and then sent to the grinding chamber of the mill evenly and quantitatively by the feeder for grinding.
The third stage: classification
The ground material is classified by the classification system, and the unqualified powder is classified by the classifier and returned to the main engine for re-grinding.
The fourth stage: the collection of finished products
The powder that conforms to the fineness is separated and collected in the dust collector through the pipeline with the airflow, and the collected product powder is sent to the finished product silo through the discharge port by the conveying device.
The fourth stage: magnetic selection
Send the phosphorous powder that meets the beneficiation requirements into the flotation machine for flotation to remove impurities
The fifth stage: drying
Phosphorus can be obtained through subsequent processes.
The equipment configuration of the complete phosphate powder production line is complicated, and the equipment selection can be planned and adjusted according to the actual production needs of customers, and the production line has a high degree of automation. The milling link in the production line is extremely important. Only by selecting the right equipment can we produce phosphate powder that meets the requirements, and can maximize efficiency and reduce energy consumption, so as to obtain ideal profits.
Jaw crushers are widely used as crushing equipment in the phosphate grinding production line. It is mainly used for the primary crushing operation of the raw material phosphate so that the crushed phosphate meets the particle size requirements required by the next construction. The equipment has the characteristics of a small footprint, simple operation, convenient maintenance, large processing capacity, energy-saving, and consumption reduction.
The cone crusher is excellent in crushing hard materials. The stable lubrication system and the excellent sealing system have significantly reduced the production cost. The overload protection system can effectively ensure the safety of the crusher. Using different crushing cavities and adjusting devices, it is easy to control the discharging particle size.
There are many models of phosphate rock powder mills. CLUM vertical roller mills, HGM ultrafine grinding mills, high-pressure mills, Raymond mills, etc. are all powerful tools for processing phosphate rock. Each series of pulverizers has different models, and suitable phosphate ore production lines can be configured for different capacity requirements.

Phosphorus powder is a kind of phosphate rock powder. Phosphate rock powder is a representative species of relatively insoluble phosphate fertilizer. Phosphate powder can be produced by grinding phosphate rock.
Phosphate rock powder generally cannot be used directly. The phosphate rock powder that can be used directly is a variety that contains a relatively high amount of weakly acidic phosphate, but not all phosphate rock can be ground and used directly as a phosphate fertilizer.
The main component of phosphate rock powder is tricalcium phosphate or fluorinated calcium phosphate, with a phosphorus content of more than 14%. The level of phosphorus content is determined by the taste of the phosphate rock.
Phosphate rock powder is more suitable as base fertilizer on acid soil, but it cannot be used as a top dressing. The amount of phosphate rock powder used as base fertilizer should be determined by the content of phosphate rock powder.
Reasonable and correct use of phosphate rock powder can not only increase the yield of crops and improve the quality of crops but also make the grains of cereal crops full, such as promoting the flowering and fruiting of cotton, melons, solanaceous vegetables, and fruit trees.
Phosphate rock powder mainly depends on the acidity in the soil, soil microorganisms, weak acid secreted by crop roots, etc. to be transformed, and then absorbed and utilized by crops.
Mineral phosphate powder is the kind of fertilizer that absorbs relatively slowly. It can maintain a fertilizer effect for several years after one use.
The washing powder contains phosphorus compounds, which can combine with the calcium and magnesium ions in the water to reduce the hardness of the water, thereby improving the decontamination effect.
Apatite refers to phosphorous ore in which phosphorus exists in igneous and metamorphic rocks in the form of crystalline apatite. It is the general term for a series of calcium-containing phosphate minerals. The shape of apatite is glass-like crystals, blocks or nodules, with various colors, mostly hexagonal cylinders with cones. The Moss hardness is 5, and the specific gravity is 3.18～3.21. Phosphorescence can often appear after heating.
