A double roll crusher is provided for mined oil sands feed, even in the winter season. Each roll has a driveline driven by a high efficiency motor controlled by a variable frequency drive (VFD). Through removal of the prior, yet ubiquitous fluid coupling and related failure-prone components, a shorter, streamlined, lower inertia driveline results.

Cone Crusher Failure Analysis 1. Preface cone crusher has been widely used in crushing process because of its large processing capacity and fine crushing size. However, in actual production, some failures often occur due to manufacturing, installation and maintenance.
Roll crushers – Roll crushers are another form of compression crusher that can be used to crush hard and abrasive materials. They represent a medium-to-high initial investment and maintenance requirements are average. Reduction ratios are up to 3:1.
was initially crushed using a double-roll bunch crusher to expose the inner layers of the bunch for steam to penetrate. As stated by Kandiah et al. [9], the short sterilisation process at the atmospheric pressure produced higher quality palm oil compared to that of the pressurised batch process (3.91% FFA, 0.58 meq/kg PV, and 2.99 DOBI).
