Feeders and their Types – IspatGuru

Sep 26, 2015  Apron feeders are used for dealing with bulk materials which are very hard, abrasive, and tough and for lumps of larger dimensions and which are beyond the scope of belt feeders. The boulders of even 1.5 m edge length dimension can be handled, because such lumps are falling on and carried by steel pans, which can have thickness of 6 mm to 40 mm.

Frequently Asked Questions (FAQs) Abrasive Water Jet ...

Pure waterjets (without abrasive) are generally used to cut soft materials like food and foam, while abrasive waterjets are used to cut hard materials like steel. Abrasive waterjets can cut virtually any material, metal and nonmetal, from carbon fiber to copper, glass to granite, titanium to tungsten and practically anything in between.
