Traditional equipment, Vertical structure
Raymond Mill is the first generation grinding mill of Liming Heavy Industry. This machine takes advantages of small covered area, low investment costs and low consumption, which can be widely used in desulfurization, metallurgy, non-metallic ore milling, etc. industries.
Applications:
Cement, coal, power plant desulfurization, metallurgy, chemical industry, non-metallic mineral, construction material, ceramics.
Overview
After many years of practice and improvement, its
structure is getting perfect day by day.
For low consumption, low investment, environment
friendly , small occupation area, and more efficient
than the traditional mill, it is widely used in the
field of metallurgy, building materials, stone
industry and mining to process powder. The series is
used in grinding the non-flammable and non-explosive
stuff which has the Moh’s hardness below 7, humidity
less than 6%, such as gypsum, talc, calcite, limestone,
marble, feldspar, barite, dolomite, granite, kaolin,
bentonite, bauxite, iron ore etc., the final products
change from 613 micron to 44 micron. Through the function
of separator and blower, it can meet different customers’
demand.
Learn More About Liming® Raymond Mill
1. The whole plant is a vertical structure of strong
systematic characteristic, so it occupies small area.
From crushing of raw material to grinding and packing
is an independent production system.
2. Compared with other milling plants, its passing
ratio achieves 99%, this is what other mill can not reach.
3. Driving system of main frame adopts airtight
gearing and pulley, drives smoothly and operates reliably.
4. Main parts of the whole plant are made from
cast and steel of high quality. The technics is so
subtly that insures the durability of whole plant.
5. The electric control system is centralized
controlled, so the automaticity is high, no people
are needed in the operating room.
Working Principle
Firstly, raw material is crushed by jaw crusher to
the size required, then the crushed materials are
elevated into a hopper from which the material is
transported through the electro-magnetic vibrating
feeder, evenly and continuously into the grinding
chamber for powder-processing. The rollers oscillate
outward to press the ring because of the centrifugal
force and the shovel scoops up the materials, send to
the middle between ring and roller to accomplish the
grind.
After this, the ground stuff are carried by the
air from the blower into the separator for screening.
The fine powers are blow into the cyclone collector
and are poured out through the output-powder valve as
the final products and the rough stuff after the screening
will be recycled back into the grinding chamber for
regrinding. The set’s airflow system is closely sealed
up and circulated under condition of negative and positive
pressure.
