Mineral processing equipment Raymond Mill



Mineral processing equipment Raymond mill is mainly used for grinding of mineral materials such as metallurgy, building materials, chemicals, mining, etc., grinding quartz, feldspar, calcite, talc, barite, fluorite, rare earth, marble, ceramic, aluminum Bauxite, manganese ore, iron ore, copper ore, phosphate rock, iron oxide red, zircon sand, slag, water slag, cement clinker, activated carbon, granite, garnet, iron oxide yellow, bean cake, fertilizer, compound fertilizer , fly ash, bituminous coal, coking coal, lignite, meimei sand, chrome oxide green, gold ore, red mud, clay, kaolin, coke, coal gangue, china clay, kyanite, fluorite, bentonite, medical stone rhyolite , non-flammable and explosive, such as pyrophyllite, shale, purple sandstone, green shale, sedimentary rock, basalt stone, gypsum, graphite, silicon carbide, heat preservation, materials, etc., with Mohs hardness below 6 and humidity at 6%. Processing of mineral products.

Applications: Calcium carbonate crushing, gypsum powder processing, power plant desulfurization, non-metallic mineral milling, coal powder preparation, etc.
Production capacity: 1-15t/h
Finished product fineness: 80-325 mesh

Performance advantage of Mineral processing equipment Raymond mill


Energy efficient

In the case of the same fineness of the finished product and the same motor power, the output of the jet mill, the agitator mill and the ball mill is more than double.

Consumable parts have a long service life

The grinding roller and the grinding ring are forged by special materials, so that the utilization degree is greatly improved. Generally, it can last for more than one year. When processing calcium carbonate and calcite, the service life can reach 2-5 years.

High safety and reliability

Since there is no rolling bearing or screw in the grinding chamber, there is no problem that the bearing and its sealing member are vulnerable, and there is no problem that the screw is loose and the machine is destroyed.

Environmentally friendly, clean

The dust collector is used to capture dust, and the muffler is used to reduce noise, which is environmentally friendly and clean.
 
 

Mineral processing equipment Raymond mill structure

 
The complete set of Raymond mill consists of main engine, reducer, analysis machine, pipeline device, blower, dust collector, jaw crusher, bucket elevator, electromagnetic vibration feeder and electronic control system.
 

Precautions in the operation of Mineral processing equipment Raymond mill

 
The first is that during the use of the mill, professional staff should be responsible for the care. Equipment operators must have certain relevant technical levels. Before the installation of the mill, the operator must carry out the necessary technical training to understand the principle performance of the mill and familiar with the operating procedures, so as not to solve the problem in time.
 
Secondly, in order to make the mill work normally, relevant safety operation instructions should be formulated to ensure long-term safe operation of the equipment. At the same time, the equipment must be equipped with the necessary maintenance tools as well as grease and corresponding accessories.
 
The mill should be regularly inspected during use. At the same time, it is necessary to pay attention to the maintenance of wearing parts such as the grinding roller and the blade. If there is wear, it should be replaced immediately to avoid further damage.
 

Working principle of Mineral processing equipment Raymond mill

 
In the Raymond mill, a Raymond spring with a pressure of 1000-500 kg is fastened on the roller hanger. After starting work, the grinding roller rotates around the main shaft, and under the tension of the Raymond spring and the centrifugal force, it is close to the grinding ring, and its rolling pressure is 20% higher than that of the Raymond mill under the same dynamic condition, so the output is greatly improved. .
 
When the material to be ground enters the grinding chamber, it is shoveled by the blade and sent to the grinding roller and the grinding ring for rolling. The powder after rolling is brought into the analysis machine along with the circulating wind of the blower, and the qualified fine powder enters the cyclone with the airflow. The powder is the finished product, and the large particles are re-grinded behind. The circulating air returns to the blower and repeats the above process, and the residual wind enters the bag filter.
 
When the grinding roller and the grinding ring reach a certain degree of wear, adjust the length of the Raymond spring to maintain a constant rolling pressure between the grinding roller and the grinding ring, thereby ensuring stable yield and fineness.
