We can procedure 3 m length tube by using of ...
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 applications.

Pollution and the global health impacts from toxic environmental pollutants are presently of great concern. At present, more than 100 million people are at risk from exposure to a plethora of toxic organic and inorganic pollutants.
The resulting cone is formed using the appropriate pit slope angles. If the total revenues are greater than the total costs for the blocks in the cone, the cone has a positive net value and is economic to mine. A second block is then examined, as shown in Fig. 9. Each block in the deposit is examined in turn as a base block of a cone. 69.
When durability is a concern, w/cm ratios should be specified. For informational purposes, various w/cm ratios are likely to produce the following relative compressive strengths or higher: .50 [4000 psi Entrained air is necessary in concrete subjected to freezing and thawing when moist, or subjected to deicing chemicals.

Concrete mixing ratios are the formula for calculating the correct amount of each ingredient used, including water, cement, sand and aggregate, to produce concrete with the properties desired. Add water following manufacturer's recommendation and then add the dry hydraulic cement mix. Sikacryl® Ready-Mix Concrete Patch June 2018, Version 01.
Cone crushers can in most cases also give a good cubic shape to fine grades. They can be adapted to different applications. This is an important factor, as client-specific needs often change during a crusher's lifetime. For cone crushers there are few rules to be followed of optimum cubical shape. These 'Ten Golden Rules' are:
