    [prod_name] =&gt; Jaw Crusher  BB 300
    [prod_intro] =&gt; The Jaw Crusher BB 300 is used for the rapid, gentle crushing and pre-crushing of medium-hard, hard, brittle and tough materials.&amp;nbsp;Its variety of materials offered, such as heavy-metal free steel, efficiency and safety makes&amp;nbsp;it ideal for sample preparation in laboratories and industrial plants. 
    [prod_examples] =&gt; alloys,  basalt, cement clinker,  ceramics,  chamotte,  coal,  coke,  construction materials,  feldspar,  glass,  granite,  minerals,  ores,  oxide ceramics,  quartz,  rocks,  silicon,  slag,  ...
    [prod_advantages] =&gt; high throughput, high degree of size reduction
high final fineness (down to d90 &lt; 5 mm)
continuous gap width setting
scale for gap width display
zero point adjustment for wear compensation
particularly economical
breaking jaws made of 4 different materials
no-rebound feed hopper withquick-release clamp
brake motor with safety switch
easy-to-clean crushing chamber
incl. connection for dust extraction
process line version available
warranty period 2 years; CE-conforming

    [prod_principle] =&gt; The Jaw Crusher BB 300 is&amp;nbsp;a robust and powerful forced-feed crusher. The feed material passes through the no-rebound hopper and enters the crushing chamber. Size reduction takes place in the wedgeshaped area between the fixed crushing arm and one moved by an eccentric drive shaft. The elliptical motion crushes the sample which then falls under gravity. As soon as the sample is smaller than the discharge gap width, it falls into a removable collector. The continuous gap width setting with scale ensure optimal size reduction in accordance with the set gap width value.

	<h4>Function Principle</h4>
	<div class="foldBoxContent">
		<img src="typo3temp/pics/e5679b211b.jpg" width="212" height="200" border="0" align=right alt="" title="" />The Jaw Crusher BB 300 is&nbsp;a robust and powerful forced-feed crusher. The feed material passes through the no-rebound hopper and enters the crushing chamber. Size reduction takes place in the wedgeshaped area between the fixed crushing arm and one moved by an eccentric drive shaft. The elliptical motion crushes the sample which then falls under gravity. As soon as the sample is smaller than the discharge gap width, it falls into a removable collector. The continuous gap width setting with scale ensure optimal size reduction in accordance with the set gap width value.
