The?Combined?Self-fastened?Boltless?Ball?Mill?Liners

This?product,?invented?by?Mr.?Chen?Changshun,?senior?engineer?and?the?director?of?the?company,?is?known?

as?“China?Best?Liner”.It?includes?two?parts,?high?wear?resistance?boltless?plates,?and?highly?expandable?

riveting plates,?which?are?self-fastened and?strengthened?to?withstand?impact?from?mill?balls.

We?possess?famous?patented?product------

Combined?Self-fastened?(Boltless)?Ball?Mill?Liners,?or?called?CHINA?BEST?LINER.?

In?2012,?we?registered?a?new?patent?about?Liner?Technology.

In?December?of?2000,?we?successfully?registered?the?international?patent?in?Canada.?

In?1988?and?1997,?we?claimed?domestic?patents?for?ball?mill?liners?.

The?outstanding?advantage?of?our?liners?is?boltless.?

The?general?advantages?in?ball?mills?are?as?follows:

The?additional?advantages?in?cement?mills?are?as?follows:

In?the?recent?20?years,?our?liners?have?been?widely?used?in?large,?medium?and?small?ball?mills?in?Chinese?

power generation,?mining,??cement,?chemical?engineering?and?metallurgical?industries?and?super?fine?

pulverizing?equipments.

It?is?the?only?recommended?linerproduct?in?the?latest?standard?of?the?electric-power?industry?in?China.

Materials?1:?Double-Media?Quenching?Chromium-Molybdenum?Alloy?Steel?Series

We?specially?design?the?material?for?ball?mill?liners?in?mines,?coalfired?power?plants?and?cement?plants,?etc..?

With?our?special?doublemedia?quenching?process,?the?material?can?not?only?achieve?ideal?hardness?

(HRC48~55)?but?also?ideal?toughness?value?(AK30~100J).?It?can?completely?meet?the?requirement?of?liners?

of large?and?middle-size?ball?mills?at?home?and?abroad.??The?match?of?Middle?Chrome?Liners?and?High?

Chrome?Cast?Balls?has?been?the?typical?model?in?coal?mills?and?cement?mills.?Meanwhile,?the?material?is?

applicable to?the?teeth?plates,?armored?plates?and?hammers?of?crushers?and?excavator?bucket?teeth.

Materials?2:?Pearlitic?Chromium-Molybdenum?Alloy?Steel?Series

The?Pearlitic?Chromium-Molybdenum?Alloy?Steel?Liners?are?widely?used?in?AG?Mill,SAG?Mill?and?Ball?Mills.??

Hardness:?HB310-375?(equivalent?to?HRC33-42)

Impact?resistant?Value:?Ak≥60J?(60×10×10mm)?in?normal?ambient?temperature.

We?can?produce?pearlitic?Cr-Mo?steel?as?per?AS2074?Gr.?L?/?2B.?

Materials?3?:?High?Chrome?White?Iron?Series

High?Chrome?white?iron?we?can?produce?include?15%Cr,?18%Cr,?20%Cr?and?26%Cr.?Under?same?working?

condition, the?wear?performance?of?High?Chrome?mill?liners?is?four?times?of?that?of?high?manganese?steel?

liners?and?twice?of?that?of low?Chrome?alloy?steel?liners.Meanwhile,?we?can?produce?high?Chrome?castings?

as?per?AS2027,?ASTM?A532?and?BS4844.

Customer-made?Mill?Liners

In?addition?to?our?patented?Boltless?Mill?Liners,?we?can?produce?liners?as?per?the?request?of?customers.?

So?far,?we?have?been?the?regular?suppliers?of?mill?liners?for?Magotteaux?and?Foster?Wheeler?Power?Group.?

Now,?we?have?supplied?steel?caps?inserted?in?rubber?lifters?for?SAG?mills?and?AG?mills?to?some?mines?in?
