1, water seal --- blankets dust-proof device
Select the thickness of 3-8mm industrial blankets, cone crusher bowl bearing frame back to the outer edge of the tank, with the pressure plate will be fixed on its felt. Felt to ensure a high degree of compression of 3-5mm. After the blankets installed, should be doused with oil to reduce the wear of felt, which is a two dust-proof device, dust seal in the water seal device, most of the coarse dust has fallen into the water, a part of fine dust fly From here, is blocked by blankets, thus preventing the dust into the lubrication system. This method is simple, the sealing effect is good, long service life. Use 2 months after the open inspection and found that bowl-shaped bearings are very clean, no fine sand and dust, lubricating oil quality basically no change, blankets intact.

In this case,
2, apron vice - water seal dust - proof device
According to the conical crusher drive inside and outside the bowl-shaped bearing frame to make a rubber ring, the cone-shaped apron 2 installed in the bowl-shaped bearing frame, the cylinder mounted on the cone in the cone, and to ensure Aprons are in close contact in any direction see figure). In the crusher work, the tube with the crusher with the rotation and swing, and bowl-shaped bearing on the cone-shaped apron in the role of elastic, and always close with the cylinder-shaped rubber ring. Thus avoiding the entry of dust. But because of the production and installation of the error, making a very small part of the dust into the sink. Therefore, the use of water-sealed dust-proof device. In this case,
This dust-proof device is essentially two dust, apron material must have good flexibility, abrasion resistance and heat resistance, the current rubber plate is still very difficult to find. Using ordinary rubber sheet or V-belt, the service life is very short.
In this case,

3, foam dust-proof device
First, the conical crusher bowl bearing frame dust ring removed, and the ring back to the sink clean, and then select the appropriate thickness (generally larger than the width of the sink 10-20mm) of the foam material, cut into "mouth" Shaped, its height to ensure a 20-30mm telescopic amount, with "309 glue" can be fixed in the back tank. When the crusher is running, it relies on the elasticity of foam and always close to the spherical ring, thus avoiding the possibility of dust into. In this case,
As the work of a large number of dust into the foam, so that the foam hardening, reducing elasticity and loss of dust, so the service life is short.
