  • 3 Key Principles of the Spiral Curriculum (Bruner), Explained!

    The spiral approach to curriculum design reminds us that courses are not singular, set-in-stone units of work. Each course or unit of work that we cover builds upon something previously. This approach forces us to work with our colleagues who were a childs teacher in a previous year or in years to come to develop a cohesive approach to teaching.

  • Spiral Concentrators - Mine Engineer.Com

    The design and shape of the spiral make it work, when combined with gravitational acceleration. As the slurry travels the spiraling path down the spiral, mineral grains settle and start sorting according to size, density and to a lesser extend shape. Low density particles are carried with the bulk of the water towards the outside of the spiral

    Principle of Spiral bimetallic thermometer. When a bimetallic spiral fixed at one end and free at the other end is subjected to a temperature change, the free end of the bimetallic spiral deflects proportional to the change in temperature. This deflection becomes a measure of the change in temperature. Description of Spiral Bimetallic Thermometer

  • How do spiral concentrators work? Multotec Canada

    How exactly do they work? Slurry is pumped to the upper part of the spiral, which is usually 13' to 15' from the floor.
