In addition, the direction of side plate can be adjusted upside down after it’s partially damaged, which will be able to bump up material using rate and prolong life span by more than 48%. As for the sand making machine in Botswana, the deep rotor VSI crusher plays the role of artificial sand making machine, which integrates many patents and three crushing methods, is a new and high efficiency crusher. Besides, the core abrasion-resistant spare parts are made of high degree wear-resistant and temperature-resistant materials. The adaptation of deep chamber makes the throughput of materials increase by about 30%.In the artificial sand production line, the sand making machinery consists of the sand making machine and sand washing machine. Today, more and more sand producers choose the deep rotor VSI crusher as their favored sand making machine in Botswana.

The material is fed in to the jaw crusher by the vibrating feeder for primary crushing, immediately after crushing , the material will likely be fed into cone crusher by belt conveyor for secondary crushing. the fine supplies with belt conveyor are sended towards the circle vibrating screen for screening unique specifications of finished item stone, but not qualified stone will return towards the cone crusher.

Lead and zinc ore crusher machine can process the useful and high economic value materials. Choose the suitable crushing machine manufacturer; you will get the high productivity mining processing results.

And at the same time, we should consider about the service life of high manganese steel.The larger the size of raw material, the higher the requirement about toughness of blow bar. The higher the hardness of raw material, the more difficult to crush them, the more serious the abrasion will be and the requirement about hardness of blow bar is also higher. For different models of hammer crushers, we should adopt different feeding sizes.

It is very easy to maintain. The top of the cylinder to realize adjusting the discharging mouth size and overload protection, it will replace the multi cylinder and hydraulic motor and adjusting ring part. Getting rid of the inner spherical bearing and the stable institutions, it can make the crusher structure greatly simplified. The new scheme adopts high-energy laminating crushing principle to ensure the superiority of the crusher performance. Secondly, on the structure, the single-cylinder hydraulic cone crusher machine is the simplest one.From the above analysis of HP series cone crusher machine, we can find that its great performance is for its superior performance. Therefore, it should adopt the top hydraulic support device which will form at the top of the single-cylinder hydraulic cone crusher machine. The new type cone crusher machine will reduce the manufacturing process and the heavy machine weight and manufacturing cost.

[38] using DEM simulations, the main cause for the drop in energy efficiency in particle bed breakage is the reduction in the voids that are caused by fine debris relocating themselves as a result of the application of high normal applied stresses.As already reported by Schönert [14] and recently observed by Zhou et al. Such a drop in energy efficiency in compressed bed breakage is also evident in Figure 9 for specific energies higher than about 6 kWh/t.
