200-400 mesh output size ultra fine grinding mill with cheap price

As we all know, raymond grinding mill was ever popular in the industries such as mining, building materials, chemical engineering and metallurgy industries for size reduction, dispersion, or specialized needs, powder generation and processing for industrial process. 

Grinding mill machine, raymond mill is a leading word level industrial mill. It is designed by our engineers and technical workers, basing on many years industrial mill design, adopting world leading powder making technology. Our machine adopts numbers of national patents of mill, such as trapezium working surface, flexible connection, roll linked pressure boost, etc. It has totally covered many defects of traditional mill, like application, capacity, fineness, energy consumption, service life, etc and it is the ideal substitute of traditional mill, such as high pressure suspension mill, ball mill, etc.

Nowadays, it has been widely used in electric power coal industry, fireproofing, etc. and it has achieved large economic benefits and social benefits.

ultra fine grinding mill application:

Raymond mill is widely used in mining industry, also is popular in building materials, chemical engineering and metallurgy industries. It can grind the non-flammable and non-explosive materials such as barite, calcite, potash feldspar, dolomite, gypsum, talcum, mica, marble, limestone, kaolin, clay, coal etc. It also has wide applications.

ultra fine grinding mill working principle:

The whole machine is collocated with jaw crusher, elevator, hopper, electromagnetic vibrating feeder, main unit, classifier, collector, cloth deduster and high-pressure blower.
The working principle is as follows: load the stuff for grinding evenly and continuously into the grinding chamber of the main frame. Due to the centrifugal force in rotation, the roller swings go outward and presses closely upon the ring. The shovel carries the stuff to the space between the roller and ring. When the roller rolls, the stuff is thus grinded.
After being grinded, the stuff is to be routed to the classifier along wind belt of the blower and the rough powder will be put back to the grinder for regrinding. 
The fine powder flows into the cyclone collector together with air flow and is expelled from the powder output pipe as product.
In the grinding chamber, since the stuff contains moisture to some extent, the heat generated during grinding makes the moisture evaporate; since the pipeline joints are not airtight, the external air is sucked in and the circulation air mass increases. In order to enable the grinder to work in negative pressure, the increased air flow is guided to the deuster and sequentially to the atmosphere after purification.

ultra fine grinding mill advantages:

1.Take small area.
2.Simple structure and easy operation.
3.Closed system and steady performance
4.Adopt durable material.
5.It has long service life.
6.It can be controlled intensively and high automation
