Step 1

Make a new document, with dimensions 200x200 px. Give this document any name you wish

Step 2

Make a new group, which you should call Bars. Select the rounded rectange tool, under the rectange tool menu, and set the radius to 10 px. Inside this group, make a drawing with the colour #999999, then rasterize it to make it look like this;

Duplicate this layer 11 times (until you have 12 of these layers), rotate them and move them until you get something like this; DO NOT WORRY ABOUT IT BEING UNEVEN!

Step 3

Select the ellipse tool, under the rectangle tool menu, and make a selection about this big and place it roughly in the middle of the image;

Step 4

Keeping our last selection, delete each line in turn by clicking on the layer you wish to delete the line from, and press delete on your keyboard. Merge the layers. You should end up with something like this.

Step 5

Right, lets create the highlight for the pre-loader by making a triangular selection

Step 7

Make a new group and call it Highlight. Then make a new layer with the triangular selection still up. Change the foreground colour to #595959, and select the gradient tool. Set it to the reflected gradient and make the gradient foreground to transparent. make this gradient by making the line start in the middle of the triangle and making it end on either edge.

Step 8

Duplicate this layer so you have 12 of these gradients. Keep moving and rotating them until you get each triangle to have its point on the middle of the opoosite bar.

Step 9

Select every point of the bars (ctrl+shift+click on each layer image), and select the inverse (ctrl+shift+I). On every gradient delete this part until you are left with this.

Step 10

Open up the animation toolbar (Window>Animation), and on the first frame hide all gradient layers escept the first one. Add a new frame once you have done this and add on the gradient that goes next clockwise in the circle. Hide the the last gradient layer and then repeat this for the whole way round.

Step 11

If you want you can change the color of this easily by upressing ctrl+U, clicking colorize, and choosing the color. See below for the two possible final products.
