Phosphate ore industrial grinding equipment

Number of hits:0   Update time:2021-11-01 10:55:28     Source:

Phosphate ore industrial grinding equipment includes crushers, pulverizers, flotation machines and so on. Today we mainly introduce phosphate ore mills, which include ultra-fine mills, vertical mills, high-pressure mills and wet mills. It can produce 50-6000 mesh phosphate rock powder with stable operation and high efficiency and energy saving.


About phosphate rock

Phosphate ore is a phosphorus-containing ore, which is mostly produced in sedimentary rocks, but also in metamorphic and igneous rocks. The main component of phosphate rock is apatite, which is an important chemical raw material, mainly used to extract phosphorus, and can be used to make phosphate fertilizer, phosphate, yellow phosphorus, etc., in metallurgy, textile, mineral processing, machinery, ceramics, glass , Refractory materials, printing and dyeing, leather making and other fields have a very wide range of uses.



Phosphate ore processing process

Phosphate ore processing technology adopts flotation method, which generally needs to go through the four processes of crushing, grinding, flotation, and drying. Next, I will introduce the specific process of phosphate ore flotation production line in detail:

1. Crushing and screening stage

First, the large phosphate rock is sent to the jaw crusher for coarse crushing by the vibrating feeder, and then sent to the cone crusher by the conveyor for fine crushing. Then enter the circular vibrating screen to be sieved and classified. The qualified materials are sent to the silo to be processed, and the unqualified materials are sent back to the crusher to continue crushing.

2. Grinding and classification stage

The phosphate rock that fits into the mill size is transported to the industrial mill for grinding. The ground powder is sieved through the classifier along with the airflow. The qualified powder passes through the classifier and finally enters the powder collection bin, and the unqualified powder is sent to the grinding chamber to continue grinding.

3. Flotation separation stage

The graded phosphate ore slurry is stirred by a mixing tank and sent to the flotation machine. At this time, a reasonable flotation agent is added, and after 1 coarse, 3 sweep, and 1 fine flotation, a preliminary phosphate concentrate can be obtained.

4. Drying and dehydration stage

Phosphate concentrate contains a certain amount of water, so it needs to be concentrated and precipitated in the thickener, and then into the dryer for drying and dewatering to obtain high-grade concentrated mineral materials.


Introduction of Phosphate Rock Mill

The milling process is an indispensable part of the phosphate rock production line. The fineness and quality of the final product powder mainly depends on the mill.


150-5000mesh powder >>

Medium and high-end powder

 ultrafine powder mill

HGM Superfine Powder Mill


The newly designed grinding roller grinding ring grinding curve improves the grinding efficiency. The production capacity is 40% higher than that of jet mills and stirring mills, and the energy consumption is only 30% of that of jet mills.

Equipped with multi-head cage type powder concentrator. The fineness of the product can be adjusted arbitrarily between 150-3000 mesh, and the one-time screening rate can reach d97≤5μm.

The lubrication device is installed outside the main shaft, which can realize external non-stop lubrication and continuous production for 24 hours.

HGM superfine powder grinding mill is equipped with a high-efficiency pulse dust collector, so there will be no dust pollution during the operation of the entire crushing system. Equipped with silencer and anechoic room to reduce noise.


High-end powder

 verticla roller mill

CLUM Vertical Roller Mill


SBM specially designed a unique roller shell and liner grinding curve, which can greatly improve the working efficiency of the mill and improve the whiteness and cleanliness of the finished product.

Using a PLC control system and multi-head powder selection technology, it can precisely control the working parameters of the equipment such as grinding pressure and speed. Compared with ordinary mills, the energy consumption of this mill can be reduced by 30%-50%.

The contact point between the roller shell and the grinding disc liner adopts electronic limit technology and mechanical limit protection technology, which can avoid the destructive impact caused by machine vibration and ensure the stability of operation.

Through the reversible structure and hydraulic adjustment system, the operator can easily and quickly move the grinding roller out of the machine body, inspect and replace the roller shell and liner, and perform other maintenance operations to reduce downtime losses.


325-6000mesh powder >>


wet mill


Wet Stirring Mill


Ultrafine powders, reach 2 microns with a content of 90% for milling one time.

Has a large output, high efficiency, low energy consumption, environmental protection, and other features.

Vertical-shaped star wheel reducer higher transmission efficiency, run more smoothly.

Low consumption of grinding media, non-polluting. The temperature is low for finished products, good liquidity.

Compact structure, suitable height, easy operation and maintenance, stable production, automatic controlling is optional.


50-325mesh powder >>

high pressure mill

High Pressure Mill


Vertical structure, so it has a small footprint, strong system. Compared with other mills, it has a high passing rate – 99%.

The main drive device of the high-pressure mill adopts an airtight gearbox and belt pulley, the transmission is stable and the operation is reliable.

Important components are made of high-quality castings and profiles, ensuring the durability of the whole equipment.

The centralized control is used in the electric system, the mill can basically realize unmanned operation, and the maintenance is convenient.


The above is the introduction of the phosphate rock mill. Each mill has different applicable scenarios. If you are not sure how to choose, you can leave your materials and production needs, our technicians will recommend the most suitable milling equipment for you. Of course, not only the milling equipment, we can also configure the entire production line for you, and provide you with a production line configuration plan for free.
