High-quality limestone grinding mill with reasonable price and
higher output
The limestone grinding mill is an air-swept pendulum roller
grinding mill with an integral classifying system that
simultaneously dries, pulverizes and classifies a number of
different types of products, such as limestone, calcium carbonate,
calcite, bentonite, barite, petrol coke, coal, talc, dolomite,
clay, minerals and etc..
The feeding range is about from 10mm to 50mm for different model of
limestone grinding mill. This limestone grinding mill can produce
100mesh to 600 mesh powder with a sieving rate of 97% or 98%.
Applications of Limestone Grinding Mill:
This limestone grinding mill is suitable for most effective
processing materials that are 6 or less on the Mohs scale of
hardness, which is the most practical for soft to medium hard
materials. The limestone grinding mill provides efficient control
of powder fineness, resulting in a flexible, cost-effective
production. This limestone grinding mill is available with grinding
ring diameters ranging from 760-2250mm. These sizes are capable of
producing a wide range of product fineness with a wide variety of
material.
The Advantages of Limestone Grinding Mill

Easy replacement of wear parts
Simple straightforward operation
Compact design requires little floor space
Available with integral flash drying or water-cooled grinding
chamber
Working Principle of Limestone Grinding Mill:
The crushed raw material with a size of less than 20mm will be
conveyed to the hopper by elevator. And then the raw material will
go into the grinding house with the help of belt conveyor at a
fixed rate. The rollers hung upon the spider-arm are running around
the shaft. With the help of the centrifugal force, the four or five
rotational rollers will go around the ring tightly. The raw
material is lifted up between the rollers and rings by the blade,
and then to be ground into powder.
The powder is blown up to the classifier, through which the powder
is classified. Coarse particles fall back down to the mill for
regrinding. The needed particles will go into the collector, where
products will be collected through the discharge opening. The
purified air goes into the fan through the pipe above the cyclone
collector. Air stream in all pipelines is negative pressure except
for that in the fan and grinding chamber. Air volume in the whole
system increases because of the gas from the moisture in the raw
material and the air from the flange conjunctions and feeding-in
opening. The extra air volume goes into the pulse jet powder
collector. The ultrafine powder in the air stream can be collected
through the discharging valve.
