First:overview
Crusher is the universal use equipment of metallurgy,building materials,chemical industry and water & electricity departments,used in the large particles ore or rock breaking into smaller particles to facilitate the follow-up work.Crusher in general can be divided into the gyratory crusher,jaw crusher, counterattack crusher,cone crusher,rotary disc crusher and grinder,the widely application of them are gyratory crusher and cone crusher.
Gyratory crusher is used for coarse crushing,and cone crusher is mainly used for secondary crushing and fine crushing,most of these crushers use Pb-Zn alloy as the backing materials before.As the Pb-Zn alloy is toxic,and the operation temperature is high,site operation has big risk,this crusher is gradually replaced by organic backing material.Widely application of the organic backing materials mainly have two kinds of products:common performance backing compound and high performance backing filled compound.Among them,the common performance backing epoxy compound is specially used for cone crusher,the high performance backing materials are specially used for coarse gyratory crusher.They are used for construction at room temperature (15 to 40 degree),the BD66 backing materials of Xiangyang City Hundred Shield Coating Material Co.,Ltd can construct in the environment temperature of more than -5 degree,don't need the special equipment,has strong hydrolysis resistance and volume stability,thus preventing it from appearing clearance among the backing material,lining plate and the cone.The usage temperature of BD65 modified epoxy backing materials after curing is - 50 to 170 degree,the BD66 modified PU backing filling compound is -60 to 100 degree.
Second:How to use
1.The surface treatment:
Clean up the crusher cone surface and the lining plate inner surface,and remove the surface attachments.
2.Install the lining plate:
For the dynamic cone,can make the handle well lining plate (including upper and lower two segment lining plate) install on the cone directly,seal the seams well with the silly putty,clay or cement,for fixed cone,install the bottom two layers of lining plate first.
3.The preparation of adhesives:
Make the backing material B component (small drum) pour into the backing material A component(large drum) and stir them uniformly.First you had better pre-stir the backing material A component for a few minutes before mixing,then add the curing agent B component into it to mix them uniformly.When the temperature is low in winter,the viscosity of the backing material A component is large,can preheat the backing material A component up to the temperature of 25-45 degree separately,then stir and mix them.
