crusher equipment and pulverizing mills for shale crushing processing plant

Shale rock is a type of sedimentary rock formed from clay that is compacted together by pressure. They are used to make bricks and other material that is fired in a kiln. Shales characteristically consist of at least 30 percent clay minerals and substantial amounts of quartz. They also contain smaller quantities of carbonates, feldspars, iron oxides, fossils, and organic matter.

Shale is too soft and too easily broken into small pieces to be used as dimension stone or even as crushed stone (although some shale is used as slate for garden walkways and paving stones). The greatest potential use of shale today is as a new source of oil. It is presently estimated that 1.75 x 1015 barrels of oil are trapped in the worlds oil shales. This is 100 times the total liquid petroleum geologists expect will be removed from known oil reserves.

Positioned on the resource-rich ground of the original site, red shale brick uses native red shale mined from our on-site quarry guaranteeing consistent quality and processing integrity. Added to this native shale are water drawn from deep wells, filtered and tested regularly, and the finest sand from across the country to create red shale bricks.

The whole process of shale comminution usually consists of primary crushing, secondary crushing and fine crushing. Shale rock of different sizes are inserted into the jaw crushers for size reduction. Generally grinding is carried out in one or two stages, while three grinding stages can also be performed. After crushing, the material is returned to the sieving process for sizing. Depending on the desired output size of the crushed stone, the raw material may be fed to one or two impact crushers, cone crushers or complete stone grinding mills in a sequence. Thereafter, the crushed stone is transmitted to the vibrating screen to the size gradation. Product is handled by a conveyor belt to the various places of exploitation, such as jaw crusher to the vibrating screen.

Typically, jaw crusher is used in primary crushing, and impact crusher is used in secondary crushing after jaw crusher. Usually, on the basis of quarry conditions, mobile crushers are also used in the quarrying because of its convenience, high capacity and automation. To produce shale powder, a pulverizing machine is necessary in the shale powder processing plant. The commonly used grinding mills are ball mill, Raymond mill, vertical mill, trapezium mill, coarse powder mill, and ultrafine mill, etc.

As for the selection of crushers and grinding mills for shale processing, our engineers strongly recommends the following processing and crushing plant equipment for you. Among the various types of crushers, you can choose our PE series jaw crusher, JC series jaw crusher, impact crusher, hammer crusher, cone crusher and so on. In terms of shale grinding mill, ball mill, Raymond mill, vertical mill, MTM trapezium mill and medium speed super thin grinding mill can be your choice.

Our company is a manufacturer of mining and construction machinery in China. We can supply all kinds of crushers and grinders such as aggregate crusher (limestone crusher, marble, granite crusher, gravel ), coal crusher, cement mill, concrete crusher, gold ore mining equipment and so on. Since we are professional in the crushing and processing of shale, we can design and manufacture shale ore production line according to your requirements.

The Single Roll Crusher, with its 6:1 ratio of reduction, is ideal for reducing large feed lumps to a medium product size while producing a considerably lower percentage of fines. The minimum product sizing of a Single Roll Crusher is generally limited to 2-3. The crushing is carried out between the full width of the extra-long curved crushing plate and the low-speed crushing roll. The curvature of the crushing plate provides an ample throat opening to capture large irregular feed lumps. The replaceable crushing plate tips or liners are slotted to intermesh with the roll teeth to produce a cubical product and effectively reduce slabbing.

Single Roll Crushers are V-belt driven and employ a large diameter flywheel with a gear and pinion set to reduce roll speed. With the assistance of the inertia generated by the flywheel, this crusher is operated with relatively low horsepower and requires lower headroom in comparison to other crushers used for primary reduction. The roll diameter and width of the crusher will ultimately be dictated by the feed size, product size and capacity.

Single Roll Crushers employ a tramp relief mechanism to allow momentary movement of the crushing plate so the uncrushable object can pass. The mechanism then allows the crusher to return to its original setting and remain in operation.

The Single Roll Crusher, which was originally patented by Samuel Calvin McLanahan in 1894, has evolved over the years to include design features to ensure many years of rugged operation. Complete with all safety guards, the Single Roll Crusher features an automatic tramp relief mechanism that allows the crushing plate to hinge open, pass non-crushable tramp material and return to the previous setting for continued operation.

Based on the application data and extensive field experience, McLanahan selects the proper duty class of Single Roll Crusher for each project. A fully-equipped application research laboratory allows for crushing tests to make sure McLanahan can provide the best possible solution.

A Single Roll Crusher is made up of a toothed roll assembly, which crushes the incoming feed material against a crushing plate. The Single Roll Crusher is designed to reduce larger feed sizes to the desired product size at a 6:1 ratio of reduction while producing a considerably lower percentage of fines. When properly fed in the direction of the roll rotation, the crushing action is carried out along the full width of the curved crushing plate, which ensures maximum throughput capacity. A properly sized roll diameter and tooth configuration grabs the incoming feed and pulls it into the crushing zone without hesitation. The crushing plate has reversible and easily replaceable crushing plate tips, which are designed to produce a cubical product while providing the producer with twice the wear life and simplified maintenance. Single Roll Crushers often require less horsepower and lower headroom in comparison to other crushers used in primary and secondary applications.

These units are designed to make crushing simpler and more effective. McLanahan Single Roll Crushers also feature hydraulic product size adjustment to perform relatively simple changes to the crusher setting if required.

When an uncrushable object, such as metal, roof bolts/timbers, etc., enters the crusher and the force necessary to crush this material is greater than the crushing forces of the crusher, the crusher allows the crushing plate to open and pass the tramp material. The crusher then returns to its previous setting and remains in operation.

Cobra Single Roll Crushers are the lightest duty in the McLanahan line of Single Roll Crushers. They are ideal for wet, sticky feeds and for processing materials such as clean coal, petroleum coke, sulfur, rosin, foundry cores, frozen agglomerates and other friable materials.

Rockmaster Single Roll Crushers are the heaviest-duty model in the McLanahan line of Single Roll Crushers. They are ideal for the most severe crushing applications and reduce extremely hard material and typical mine refuse.

Typically designed for primary crushing, McLanahan Single Roll Crushers efficiently crush material at a 6:1 crushing ratio. . They can continually withstand heavy-impact applications. Single Roll Crushers reduce large size particles in the feed to a medium size, while producing a low percentage of fines.
