The solution which came from Europe is the closed horizontal mill, (figure5) A horizontal shaft in the horizontal grinding chamber is easy to turn with the grinding media distributed along its length. 

Estalilishing equilibrium conditions in the mill also meant that in practice a certain amount of media was always in the screen none at the top of the mill The horizontal mills do not have external screens or separators and so the media concentration in the milling chamber can be maintained at optimal level. 

The shorter shaft and disc assembly in the horizontal mill is capable of higher speed without destructive vibration (3400 ft,/min or 17 meters/sec,). The high shear rates enhance media action for particle size reduction (impact action) and agglomerate separation (shear action). 

Within this grouping of mills are several different designs including the pancake jet mill (horizontal milling chamber), the loop Jet mill (also known as oval milts), spiral jet mill, oppo.sed-jet mills (opposed jet streams), and classifier mills (Fig. 23).

The main elements of a typical knee-and-column horizontal milling machine are shown in Fig. 11.3. The elements of a vertical machine are the same except that the spindle head is mounted at the top of the column, as shown in Fig. 11.4. 

The various controls of a typical horizontal milling machine are shown in Fig. 11.7. These are identical to those of a vertical machine.

Consider machining the workpiece shown in Fig. 11.17, using in the first instance a horizontal milling machine and second producing the same workpiece using a vertical milling machine. 

Machining the undercut at stages 8 and 9 again makes use of the swivelling head, with a 5 mm diameter end mill. Alternatively, with the head vertical the workpiece can be held as for horizontal milling stages 9 and 10.

These are fixed or moveable guards, which are adjustable for a particular operation during which they remain fixed. They are particularly used with machine tools where some access to the dangerous part is required (e.g. drills, circular saws, milling machines) and where the clearance required will vary (e.g. with the size of the cutter in use on a horizontal milling machine or with the size of the timber being sawn on a circular saw bench).
