Abstract
A mixer fin such as those fixedly mounted within rotatable drum mixers. More specifically, a mixer fin comprising of a substantially non-metallic, e.g., polymeric, mixer fin such as those used within rotatable drum mixers, for example to mix concrete. The mixer fin having a non-stretchable cord disposed within the fin so as to minimize fin deformation during the mixing process.
Claims10
A mixing fin adapted to mix materials contained within a rotatable drum mixer, the fin upstanding from the interior of the mixer, and comprising a composite of:
- polymeric material having a high abrasion resistance, a high flexural modulus, and a low coefficient of friction, the polymeric material having uniformly dispersed therethrough,
- particular, plastic non-metallic material of forming a cohesive interaction with the polymeric material, the fin further comprising:
- means disposed within said fin so as to minimize fin deformation during mixing, said means comprising a non-stretchable cord.
A mixing fin adapted to mix materials contained within a rotatable drum of a cement truck, the fin upstanding from the interior of the drum and comprising substantially in its entirety composite structure, the composite structure comprising abrasion resistant, high flexural strength, low coefficient of friction, polymeric elastomeric matrix material, the elastomeric material having dispersed therethrough particulate, non-metallic plastic material, forming a cohesive interaction with the polymeric elastomeric matrix material, the fin further including therewithin:
- means disposed within the body of the fin so as to minimize fin deformation during mixing, said means comprising a flexible, non-stretchable, woven cord.
