Abstract
The lifting element (16) consists of a parallelepipedal block of elastomer designed to be fixed to the internal wall of a grinding mill and forms part of the lining of the latter. Its face (24) exposed to the grinding elements includes cavities (26) to allow the grinding elements to be embedded therein.
Claims16
Lifting element for a rotary mill having grinding implements comprising:
- a parallelepipedal block of elastomer designed to be fixed to an internal wall of said rotary mill to form part of the lining of the internal wall, wherein a face of the lifting element is exposed to the grinding implements, said face including cavities with elastomeric walls, said cavities facing away from said internal wall and shaped to embed and retain the grinding implements therein under the effect of the elasticity of the elastomer, whereby said grinding implements remain in said cavities when said rotary mill is both rotating and stationary.
Rotary mill comprising a cylindrical shell with an internal lining comprising:
- lifting elements and lining plates, wherein each of said lifting elements comprises a face exposed to grinding implements contained in the rotary mill, said face including cavities with elastomeric walls, said cavities facing away from said internal wall to embed and retain the grinding implements therein under the effect of the elasticity of the elastomer, whereby said grinding implements remain in said cavities when said rotary mill is both rotating and stationary.
Rotary mill comprising a cylindrical shell with an internal lining comprising:
- lifting elements and lining plates arranged in alternating longitudinal rows, wherein each row of the lifting elements includes, over at least part of a length of the shell, straight elements parallel to the generatrix of the shell and elements which are inclined with respect to the generatrix of the shell and wherein each of said lifting elements comprises a face exposed to grinding implements contained in the rotary mill, said face including cavities with elastomeric walls, said cavities facing away from said internal wall to embed and retain the grinding implements therein under the effect of the elasticity of the elastomer.
