Description

Powder process system of brick raw materials for production permeates water

Technical Field

The other type is a hammer crusher, the particle size of the hammer crusher is mainly concentrated at 20-50 meshes, and the prepared powder is too coarse, so that the surface of the ceramic brick is too coarse, the color is not bright, and the product performance is not stable enough when the powder particles are large; in order to enable the hammered raw materials to meet the requirement of granularity, a fine roller screen is required for screening, so that the preparation efficiency is low, the energy consumption is high, and the hammered raw materials easily block the screen.

When the roller screen is used for screening hammer broken materials, the materials are bonded on the screen mesh and gradually gathered to block the meshes in the screening process due to the fact that the raw materials contain certain moisture and the moisture content is uneven, and screening efficiency is greatly influenced. The general solution is to arrange a weight movably connected to a support framework of a central rotating shaft roller screen, one end of the weight is movably connected to the support framework, the other end of the weight strikes another section of support framework under the action of gravity and centrifugal force in the rotation process of the roller screen, and the striking forms vibration to a screen body in rotation to finally achieve the purpose of dropping off bonded materials. But the shortcoming of this scheme is that long-term hitting causes the damage to the support frame, and the drum sieve life receives serious influence, and beats the vibration that produces and can not effectively transmit to the screen cloth to clear up the material that the screen cloth blockked up.
