Adopting high quality roller bearings like Sweden SKF and America TIMKEN, it can ensure the smooth running of main unit. Based on customers' needs, Zenith's mining engineers can change our machines to adjust the practical conditions of working site. Mining engineers suggest the B series belt conveyor, which can be one single or multi-conveyors or combined with other transfer equipments according to various transferring requirements. However, belt conveyors are always combined with crushing machines to improve the capacity. The rotation speed of this rock crusher can achieve to 1700-1890 r/min. The width and length of conveying system can be adjusted based on the practical conditions of working site. Using central feeding & central cascade feeding, it can significantly ensure 720-hour work without any stop in the working site.B Series VSI Crusher, also called sand making machine is one of the most advanced impact crushers nowadays. So many applications have proved that this type of rock processing machine is very suitable for quarry owners.

Zenith mining gear and systems have proved to become dependable in mining the hardest minerals, even under intense operating circumstances.Zenith would be the world leader in mining and construction machine manufacturing engineering. Zenith is amongst the world's leading suppliers within the fields of mining and handling of lime, ore along with other minerals, as well as removal, transport and dumping of overburden. The comprehensive know-how of our really qualified engineers generates a strong foundation for the construction of such machinery.

The hardness of Cement with moisture hardening will reduce or even lose. So for the produced cement, customers should pay special attention to the moisture control to avoid moisture hardening. For wetted or hardened cement, we should first separate the lumps out and make them into fine particles.

With the development of industry and urbanization, lots of old buildings have been pulled down, which arouses lots of construction waste, which makes it very difficult to protect our environment. As a responsible supplier of mining equipment, Shanghai Zenith has been devoted to developing more advanced construction waste recycling machinery to meet the market demand. Among all types of construction waste processing equipment, mobile construction waste recycling machinery is favored by investors due to its high flexibility. Here we focus on more details of mobile construction waste recycling machinery.

The gold measured resource habitat Africa forefront. From the point of gold distribution view, the current gold deposits found in Ghana are more concentrated in its southern region.Ghana is the country with richest mineral resources of the Africa continent, especially gold resource. Known as the "Gold Coast" reputation, currently Ghana has gold reserves proven of 226 tons, while 674 tons of gold reserves in speculation, both in total about 900 tons.

An equation for calculating the threshold value for coal damage (σ) was established by Liu [39]:σ=(τ−c)(1−hD0)tanφ{1−h[D0+C1εpβ+C2(ε−εp)]}. The maximum shear stress is generated at a specific depth below the impact zone and the tensile stress is generated around the impact zone. The coal will break when the tensile stress is greater than the tensile strength of the coal. [38] think that brittle failure caused by tensile stress may be the main mode for breaking coal with a high-pressure water jet. As a kind of lastics with a large amount of porosity and many cracks, coal contains pre-existing flaws. They believe that the cracks generated propagate as radial cracks, cone cracks, or transverse cracks.However, Lu et al. If this is the case, it is more appropriate to model coal breakage based on continuum damage mechanics. For example, the mechanical parameters were obtained from porosity tests and uniaxial compression tests on a coal from a coal mine in Chongqing, China.
