The process of crushing coal to a more manageable size is an important step in the processing chain. Primary crushers reduce a wide range of large Run of Mine RoM coal to either a marketable product or a range that can be more easily handled by the preparation plant. More recently, as large mines try to crush RoM coal to a saleable product, the industry has seen the size of primary crushers grow. Moreover, crusher manufacturers are making improvements to the equipment that extends the life of the rolls and the average time between maintenance.
In the eastern U.S., where a majority of the coal production is washed, primary crushers are usually reducing a 20- to 24-inch feed to a more easily conveyed 4- to 6-inch top size. In the West, especially at large surface mines such as those found in the Powder River Basin PRB, the raw feed to the primary crusher can be as high as 60 to 70 inches. Because the RoM characteristics, these mines do not wash coal and they are looking to create a direct-ship, 2-inch product. Employing some of the largest primary coal crushers, they are reducing 20- to 70-inch RoM coal to 2 inches in a single pass.
Real estate comes at a premium in coal country and another noticeable trend is that the mines want one piece of equipment that could do the job without multiple stages of handling in the smallest footprint possible, Hamby explained. Todays crusher manufacturers are seeing more larger applications, 500 to 800 tons per hour tph, rather than the traditional smaller installations 150 to 200 tph.
As far as improvements, Hamby sees a number of refinements being implemented to make todays machines better. Gundlach has a coupling-mounted roll that allows quick removal and replacement. The company also offers a gear box that allows for the timing of the rolls to eliminate or dramatically grinding and reduce fines generation.
Wear materials is another area that Hamby says crusher manufacturers have made great improvements. We just replaced a set of rolls in the PRB that had 50 million tons of life, Hamby said. As little as 15 years ago, we were very happy to get 8 million tons out of that same application.
Crusher Selection amp ApplicationWhen selecting a primary crusher, a mine needs to consider several parameters, explained George Edmiston, mineral division sales manager, McLanahan Corp.
Some of the factors that dictate the selection of the crushing equipment include the desired product size, capacity, the HGI Hardgrove Grindability Index , percentage of rock in the feed and the hardness of that rock, Edmiston said. Since many of the available types of crushers cross over application lines, other considerations such as space restrictions, mining methods and cost may also figure into the final decision of crusher selection. Edmiston presented a paper at Coal Prep 2009 on the application of crusher types.
The single roll crusher with its 61 ratio of reduction is ideal for reducing large feed lumps to a medium size product while producing a considerably lower percentage of fines, Edmiston said.
Minimum product sizing of a single roll crusher is generally limited to 2 to 3 inches. The crushing is carried out along the full width of the extra long, curved crushing plate and a low speed crushing roll.
The curvature of the crushing plate provides an ample throat opening to capture large irregular feed lumps, Edmiston explained. The replaceable crushing plate tips or liners are slotted to intermesh with the roll teeth to produce a cubical product and effectively reduce slabbing, Edmiston said.
