Feldspar grinding mill is used to grind non-flammable and non-explosive materials with a Mohs hardness under six, such as feldspar, into fine powders between 300-3000 mesh. It works by crushing materials between rollers and grinding rings to produce powder, which is then classified and reground if needed until reaching the desired fineness. Compared to other mills, it has high efficiency, long wearing part lifetimes up to years, high safety and reliability as there are no bearings, and can produce very fine powders down to 5 microns.

Abstract: Feldspar is a common raw material used in glassmaking, ceramics, and to some extent
as a filler and extender in paint, plastics, and rubber. Feldspar grinding mill is mainly applied to
grind non-inflammable, non-explosive and brittle materials with Mohs hardness under six.

Brief overview feldspar:
Feldspar is a common raw material used in glassmaking, ceramics, and to some extent as a filler
and extender in paint, plastics, and rubber. In glassmaking, alumina from feldspar improves
product hardness, durability, and resistance to chemical corrosion. In ceramics, the alkalis in
feldspar (calcium oxide, potassium oxide, and sodium oxide) act as a flux, lowering the melting
temperature of a mixture. Fluxes melt at an early stage in the firing process, forming a glassy
matrix that bonds the other components of the system together. In the US, about 66% of feldspar
is consumed in glassmaking, including glass containers and glass fiber. Pottery (including electrical
insulators, sanitaryware, tableware, and tile) and other uses, such as fillers, accounted for the
remainder.
Working Principle of Feldspar grinding mill
The main bearing and each dial are driven by electromotor of main machine through reducer,
and numbers of rollers, which are rolling in the ring, are driven by dial through plunger. After

2. crushed by hammer crusher, the big materials become small ones and are sent to storage hopper
by elevator and further sent to the middle of first dial evenly by the electromagnetic vibrating
feeder and feeding pipe. The materials will be driven to the edge of dial by centrifugal force and
fall down into the ring, crushed and grinded by roller, and become powder after production of
three rings. The high pressure centrifugal blower will inhale air from outside and blow the
crushed materials to classifier. The rotating turbo in the powder concentrator will make the
coarse powder return to the mill and reground, while the fineness will mix with the air and go
into the cyclone and be discharged in the discharge bin, which is at the bottom of it. The air,
which mixed with very little fineness, will be purified by impulse duster and discharged by blower
and muffler.
Feldspar grinding mill:
Feldspar grinding mill is mainly applied to grind non-inflammable, non-explosive and brittle
materials with Mohs hardness under six. Such as calcite, chalk, limestone, dolomite, kaolin,
gypsum, and talc etc, totally more than 100 kinds of materials. Product fineness can be controlled
between 300~3000 mesh (47~5 micron)
Comparable with ball mill, Feldspar grinding mill has features of low cost, high capacity, easy
operation; Comparable with Raymond mill for coarse powder up to 325 meshes, it can produce
fine powders between 47 and 5 microns (300 to 3000 meshes)
Performance and features of Feldspar grinding mill
1.High efficiency
Under the same final size and power, the product capacity of micro powder grinding mill is twice
than jet mill and agitation mill.
2.Long lifetime of wearing parts
The roller and ring are made of special material, which improve the grinding efficiency a lot. For
same material and final size, the lifetime of its wearing parts can reach to more than one year,
about 2-5 times as long as that of vertical shaft impact crusher and turbo-mill. Especially when
handling calcium carbonate and calcite, the lifetime can reach 2-5 years.
3.High safety and reliability
There are no rolling bearings and bolts in grinding cavity, so problems caused by bolts shedding
or wear of bearings and seal components will never happen.
4.High fineness of products
The product fineness can reach D97 5 m.
5.Environment friendly
The application of DMC-120pulse dust collector and muffler reduce the pollution and noise of the
dust, which has reached national environment protection standard
