Cone crusher frequently is used in mining ore beneficiation, medium crushing and tertairy crushing. The transferring cone
liner, set cone liner and
ore minerials type a three-dimensional abrasivation, to be certain which the liner surface area
is inside a condition of advanced pressure and pressure. The broken
stone provides liner floor a great compressive
pressure. In the equivalent time,
large rate shifting cone liner generates large shear stress. Both of these types of
stresses do chisel reduce, slicing, and influence extrusion pit on
liner board, that is the basic principle pressure
technique. For that reason, as for liner product, we calls for not only substantial surface area hardness to chisel
edge,
but will also larger electricalsand making machine power and toughness. Given that the special doing work web-site ailment, mainly the ore
hardness value is assorted, three varieties
of stresses strategies can also be unique from one a further. At current, we
ordinarily decide for high-manganese metal as cone crusher liner board.
Thinking of that a English, Hatfield has
investigated austenitic high-manganese metal competently in 1883, the fabric had been presented
"wear resist
steel", now is widely utilized in put on resistant parts in all walks.
This metal possesses Austenitic microstructure
at room temperature, also known as austenitic higher manganese steel. The vast majority of high-
manganese steel made use
of for castings. Its microstructure of high-manganese steel guaranteed wear resistance. The chemical composition of the
substantial manganese metal N1, C = 1 2% 4%, Mn = Il% to 14%, P ≤ 0.06%, Si = 0.5% 1 0%, S ≤ O. 03%. Substantial
manganese steel castings should
be preheated before putting in use. The heated treatment hardness is HB = 179-229. After
quenching, the hardness of high-manganese metal is not
substantial, but the strong effects power or worry will produce
hardening phonomenon, the hardness value may be increased to HB = 450 – 550.
Hardening is formed just at floor 3-6 mm in
depth. This is definitely the purpose to superior manganese steel’s substantial resistant. High-
manganese metal was first
utilized within the production of anti-wear pieces for more than 100 years, which has good electrical power, toughness,
hardening
when in use, resistance to abrasive wear, so until now it is still in application.
Rotary drum dryer could be
the heat and dry device of materials. Rotary dryer is employed for drying materials with humidity or granularity
while
while in the industries of mineral dressing, constructing materials, metallurgy and chemical. It may be made use of for
drying lots of types
of materials this kind of as limstone slag, coal powder, clay stone etc. It has benefit of
realistic construction, efficiency, low energy consumption.
Rotary dryer mostly includes rotary entire body, raw materials feeding
blade, driving and supporting gadget, sealing ring and and
so on.Rotary drum dryer has powerful anti-overload ability,
substantial managing capability, less fuel consumption, reduced dry expense.
Main characteristic of Rotary drum dryer :
1.
dry mining tools has solid anti-overload skill, significant managing capacity, significantly less fuel consumption,
minimal dry cost.
2. flour dryer adopt latest approach to dry.The moist flue fuel and product is same side to the drying
machine, functioning with large temperature
fume to attain incredibly large ability of evaporation.
the exit of rotary
dehydrator displays very low temperature and increased thermal efficiency.
3.According to various material properties to
alter operation parameters, making the material during the flour dryer to kind a secure cylinder
entire body .The heat
exchange is more adequate .
4.The brand new feeding and discharging device remove the drum drying machine feeding jams,
discontinuity, uneven return the phenomenon . and
decrease the dust elimination method load.
5.The new inner framework
strengthened the clean of
scattered elements and heat transfer affect, eliminates the cylinder entire body of the wall
with glue phenomenon,it adapt drastically to
materials moisture.
6.rotary drying machine achive ‘Zero level
thrust’,significantly decreases the wheel wear along with the cylinder body smooth operation and
trusted
7.In accordance
to user’s requirment to control product dimension and moisture, coal slime water items may be decrease than 8% when
drying , the
particle dimension is often controlled in 8 mm below.
