Concrete Mixer Mixing Blade The blade is an important part of the blending system in concrete mixer.The blade determines the reconciliation system.Therefore, the operators of the concrete mixer need to understand the speed of the blade of the mixing system which will be able to ensure the good use of the concrete mixer. Material: cast iron,cast steel,alloy. Extreme wear resistance. Complete the mixing action and give fast discharge. Outer edges are thickened to equalize wear and the angle of attack is optimized to push,not slice,to minimize both mixing and blade life.Durable Concrete Mixer Wear Parts website:http://www.hwm-parts.com/concrete-mixer-spare-parts/concrete-mixer-wear-parts/
