	The LAKER extruder type EV is fabricated entirely from welded and normalised steel, has a low energy consumption and, particularly for customers with limited space, is very compact. Its main characteristic is that just one motor powers the feeding and extruding group which are both aligned on the same shaft.
Traditional gears have been replaced with a special planetary system driven by a direct current motor or by an alternating current motor with inverter speed control. This particular solution allows a variable output depending on the material, removing surges of the auger and therefore passive wear. It is also easy to obtain spare parts anywhere in the world.
	The auger barrel can be opened on hinges for ease of mainteance. Worms are made of steel, specially designed and chrome plated; other special hard-surface treatments are available if required.
Paddles in two halves for easy maintenance, independently driven and fitted in the feeder and vacuum chamber in order to avoid obstructions and surges.
	Automatic grid extractor with hidraulic system already installed in the machine.

Detail of the shaft which carries both feeding and extruding worms: between them there is a grid, made in two halves and easily dismounted, to maintain vacuum.
