Rhodax 2.1 Genesis The concept of Rhodax is the culmina-tion of a comprehensive research and development program started in the early 1990’s. The tender specifications were the following • A high reduction ratio. The crushing principle combined with the design of the wear liner allows for the.
3 The University of Melbourne, Department of Infrastructure Engineering, Victoria 3010, Australia crushing of the inner concrete wall and brittle failure. HCCs have low deformation capacity  and experience a sudden reduction in this ratio is limited to this experimental study but the behavior behind that is due to the.Jaw crushers offer reduction ratios of up to about 6 1, while cone crushers can reduce material size up to a maximum of 8 1 ratio. The finer the crushing, the smaller the reduction ratio. As a basic rule, jaw crushers are the primary crusher taking the mined aggregate and reducing it to a size that a cone crusher definition of thecrushing.
High reduction ratios and feed size flexibility. High Reduction in Medium tertiary crushing applications and their portability means they can be placed into almost any crushing Melbourne Victoria 133 Logis Boulevard Dandenong South, VIC 3175 Tel +61 3 8794 4100.Size reduction by crushing has a size lim itation for the final products. If we requir e further reduction, say below 5-20 mm, we have to use the processes of grinding.
Calculation of reduction ratio in crushing [image (135-5-3)] Crushing Equipment The selection of the right crushing equipment is influenced by many factors some of which are upstream of the crushing plant (e.g. blasting pattern and mining method) and others which are downstream of the crushing plant (e.g. mill and grinding circuit selection).Tips to maximize crushing efficiency Pit Quarry Pit . May 13, 2019 Additionally, jaw crusher feed should be prescreened using a grizzly screen prior to crushing to remove material finer than the closedside setting Setting jaw crushers Ideally, the reduction ratio of a jaw crusher should be 6to1 There are different ways to calculate reduction ratio, but the best way is something called the.
Cone crusher basics in 4 minutes. This is the starting point for understanding how cone crushers work – and how they can make your mine or quarry productive. Elsewhere on the site you can find detailed information about all aspects of crushing and screening, but to make sense of these it helps to understand the basics of cone crushing.Apr 03, 2015 It is usually employed for primary crushing with a reduction ratio of 6 to 1. Compression – As the name implies, crushing by compression is done between two surfaces, with the work being done by one or both surfaces. Jaw crushers using this method of compression are suitable for reducing extremely hard and abrasive materials.
Jan 12, 2016 Crusher Reduction Ratio. I have mentioned the fact that, as the of voids in the crushing chamber decreases, the production of fines by attrition increases. This is like saying that, as the Crusher Reduction Ratio in any given crusher is increased, the of fines in the product will increase, even though the discharge setting remains unchanged.May 13, 2019 Additionally, jaw crusher feed should be pre-screened using a grizzly screen prior to crushing to remove material finer than the closed-side setting. Setting jaw crushers. Ideally, the reduction ratio of a jaw crusher should be 6-to-1. There are different ways to calculate reduction ratio, but the best way is something called the P80 factor.
A high reduction ratio provides less recirculation in the crushing plant, thus decreasing the workload of the vibrating screens, conveyors and other crushers. As a result, overall maintenance and spare parts requirements for MEKA’s crushing and screening plants are minimal compared to competitors’ plants.Exceptional Reduction Ratio.

Metso impact crushers achieve high reduction ratios and can be used as primary or secondary crushers in rock or recycling applications. The Metso vertical shaft impactor (VSI) is THE choice in final stage crushing for the creation of high quality cubical aggregates, road base and manufactured sand. Melbourne 80-86 Frankston Dandenong Road.A general rule of thumb for applying Cone Crushers is the reduction ratio. A crusher with coarse style liners would typically have a 6 1 reduction ratio. Thus, with a 3⁄4” closed side setting, the maximum feed would be 6 x 3⁄4 or 4.5 inches. Reduction ratios of 8 1 may be possible in certain coarse crushing.
