BD67 low temperature resistant crusher backing adhesive epoxy compound

Product description of BD67 crusher low temperature repair epoxy filling material backing compounds:
The BD67 low temperature backing epoxy compound adhesive is used for filling the space between the liner plate and the matrix of
the crusher,the clearance between the rubble drum and the jacket, and the gap between the cone and the protective layer.Besides,
this kind of backing adhesive serves as the buffing material as the equipment is exposed to the impact of the crushed ores,
or when the equipment is under the circumstances of the load vibration.

Property Characteristics
Before being cured：It is safe, environment-friendly and easy to be operated, with good flow-ability and strong fill-ability.
After being cured: It features low shrinkage percentage, strong bonding performance and high-carrying capacity,and can be removed.

Typical Adhesive-spread Areas

Filling Material of Liner Plate
Fixed Cone
Rolling Mortar Wall
Crushing Wall
Movable Cone

How to use:
1 Clean up and Preparation:
First, clean up the residual fillings on the surface of the cone, as well as the grease dirt and smudge on the areas that are to be
contacted with the adhesive liquid, and then fit the cone and the liner plate together. Seal up the fitting surface and the annular
distance between the cone and the liner plate with the adhesive tape, for the fear of adhesive leakage, and for protecting the screw
threads on the shafts if necessary. Try to guarantee that the concoction and the treatment of this kind of adhesive liquid are done
at the temperature of -15-10 degree.Under the circumstances of winter, it would be best to heat A-pack separately up to be of about 25
degree temperature,so as to reduce its viscosity for making it easy to cast. For facilitating the disassembly of the equipment next time,
the surfaces of the cone and of the liner plate can be precoated with appropriate amount of machinery oil or release agent.

2 Configure crusher backing adhesive filling compound:
Open up the drum containing A-pack of BD67 backing adhesive liquid, and then stir it with the electric agitator for 2 minutes.
After that pour the B-pack into the A-pack drum while stirring these two kinds of packs to be even with the electric agitator at
the same time .Generally, the stirring time is not more than 3 minutes. Total adhesive-liquid quantity concocted at one time is
suggested not to surpass 30kg at one time. Fill the adhesive liquid into and seal up the equipment as soon as possible after the concoction.

The total operating time, namely, from starting concocting the adhesive to fishing filling it into the equipment shall not surpass 15 minutes
(at the temperature of 0 degree). At the time when the temperature surpasses 5 degree the casting time would be shortened.

3 Casting/Pouring
Pour the mixed-up BD67 adhesive liquid into a constant site of the gap between the cone and the liner plate, so as to facilitate exhaust,
and if necessary, you shall guide the adhesive liquid to flow by means of the plasticine as the cofferdam, till the liquid spills from the gap top.
Do not pour into the adhesive liquid which has not been mixed even (That means it is still of different colors). Prior to filling the
adhesive liquid into the rolling mortar wall/the crushing wall, it shall be remembered that a layer of lubricant shall be spread on the surface
of the adjusting sleeve which is contacted with the filling adhesive liquid, so as to make it convenient to exchange the liner plate.

4.Curing
Cure the adhesive liquid at the indoor temperature for 12~14 hours. The higher the curing temperature is, the faster the curing speed.
Generally the adhesive-filled equipment can be put into use after 4 hours in summer, and after 8 hours in winter.

Notes:
1.The operating temperature of BD67 backing adhesive liquid is -20-15 degree.If the cone is of the temperature not within this range,
you shall try not to spread the adhesive liquid on it.

2.In the event of excessively low temperature,the time from concocting the BD67 backing adhesive liquid to using it up shall be prolonged.
But in this way the BD67 backing adhesive liquid concocted would be of high viscosity, which makes it be difficult for casting.
Should the temperature be lower than 10 degree,you can heat A pack of the BD67 backing adhesive liquid up to be of about 25 degree
temperature and then mix it for use.

3. In the event of excessively high temperature, the time from concocting the BD67 backing adhesive liquid to using it up shall be shortened,
so does its curing time. When the temperature is higher than 5 degree,you can reduce the quantity of BD67 backing adhesive liquid
concocted at one time, and perform the casting process and the adhesive-liquid concoction side by side.

4. Total adhesive-liquid quantity concocted is suggested not to surpass 30kg.Fill the adhesive liquid into and seal up the equipment
as soon as possible after the concoction.

5. Prior to putting plenty of BD67 backing adhesive liquid into use, please use it on trial in small quantity,so as to master the skills on
how to operate it, lest mistakes could arise in the following working processes. The concocted quantity of BD67 backing adhesive liquid
can not be too much.Otherwise it would be partially cured into the solid before being filled into the equipment.

6.Avoid its contact with the skin or its entry into the eye. The adhesive- liquid-stained skin shall be cleaned up with the cleaning agent,
and the stained eyes shall first be flushed by clean water and then be treated by professional doctors.
