Overview. Mechtech SDRCs designed for primary, secondary and tertiary crushing are best suited for achieving the reduction ratios of 4:1. It is best suited for producing finer products. SDRCs are widely used and referred for their excellent reliability with simple designs and low maintenance.

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.

Double-Roll-Crushers are used for the crushing or medium-hard rock as well as for sticky and soft materials, i.e. clay, marl, limestone and similar raw materials. Sticky and soft materials are reliably crushed in 2 or 3 stages down to the required product size. Due to the low crushing ration, the thyssenkrupp Double-Roll-Crusher is producing a ...

Double roll crusher (also called twin roll crusher) is composed of two cylindrical rollers as the main working mechanism (Figure 1). When working, the two round rollers rotate in opposite directions, and the material (ore) is crushed by the friction between the rollers, which rolls the material into the crushing cavity formed by the two rollers.

Power shovels dig out the oil sands and load it into trucks which transport the oil sands to crushers that break up lumps and remove rocks. In a process called hydrotransport, the oil sand is mixed with water at either 35°C or 50°C, depending upon ... ð•Double roll crushers ð•Conveyors (8,000 tonnes/hr) ð•Slurry plant (mi x box) ð ...

Direct Drive Crushing Sizers, specifically McLanahan Sizers, provide primary, secondary and tertiary reduction of friable, low silica materials such as coal, salt, gypsum, phosphate, limestone, bauxite, petroleum coke, …

The Double Roll Crusher crushes a wide range of material types reaching compressive strengths of up to 150 MPa and higher. It is less sensitive to wet and sticky material than RollSizers and can take in larger feed sizes, making it the optimal primary crusher for soft and medium hard rocks.

The oil sand is crushed in a double roll crusher and mixed with water in a cyclofeeder, a massive vessel nearly 35 metres tall The oil sand is mixed with hot water and fed at high speeds into a pipeline to deliver it to the Extraction Plant The DoubleRoll Crushers/feederbreakers have a nominal capacity of 7,500 tonnes per hourEXCT is the …

Based on TAKRAF's significant experience in crushers and crushing plants, the world's second largest roll crusher for ductile and abrasive oil sands, with hard rock of up to 200 MPa, was successfully installed into four separate existing crushing plant locations to crush lumps of up to 2,500 mm down to a conveyable size.

The range of the smooth-face rolls, for example, is from about 400 ft/min for the small 12-in. rolls, to 2000-2200 feet/minute for the heavy-duty 72″ machine. The single-roll crusher has a tip speed of 400-450 ft/min while the 6- x 7-ft teethed roll crusher has a normal, no-load, surfaces speed of just under 3500 ft/min.

Double roll crushers (DRC) have the highest throughputs among primary crushers. In the oil sands, the hourly capacity may exceed 14,000 t/h. They are preferably used to comminute medium-hard rock ...

Marcy® Double Roll Crushers. Double Roll Crushers are useful for intermediate size reduction of hard to medium hard materials, such as rock or ore, after processing with a jaw crusher, for final reduction with a pulverizer. They also bridge the gap between laboratory and continuous production or pilot plant crushing capacities.

Double roll crushers (DRC) have the highest throughputs among primary crushers. In the oil sands, the hourly capacity may exceed 14,000 t/h. They are preferably used to comminute medium-hard rock or sticky materials. An unusual tough particle or unbreakable object may effect substantial dynamic forces in a DRC.

In addition, toothed roll crushers usually have a simple and robust design and are also suitable for sticky materials such as oil sands, clay or clay-contaminated …
