Generally, traditional blenders have moderate speed RPM motors, a bit heaving in weight, and mainly used for mixing and grinding purposes. At the end, the texture is not that smooth you will still observe few solid food ingredients. However, nutri blenders are modern age blenders having high speed RPM motor which disintegrates the food completely. This ensures that all the important nutrients, proteins, etc. get easily mixed. Nutri blenders are ideal for wet blending (smoothies, juices, purees) and dry grinding (hard spices).
