Hpc series cone crusher with high-efficiency and hydraulic pressure was widely used in mining, concrete factory, sandstone making, etc. Hpc cone crusher is one kind of our crusher with the advanced technology of the same mining equipment. The machineries pressure resistance strength is under 350mpa. And they are widely suitable for primary crushing of many kinds of mining and rock such as many kinds of ores, concrete, fireproof material, bauxite, quartzite, corundum, perlite, ironstone, basalt, etc. Features and benefits : 1.The new series of hpc cone crusher with high-efficiency and hydraulic pressure equipment is adopted three protecting equipment such as protecting oilcan, locking oilcan and hydraulic driving oilcan. They not only protect the machinery, but could deal with troubles without disassembly the parts. 2.The equipment also can adjust the size of final material. The machinery with high dependability operated very expediently. 3. The crushing chamber specially designed according to particles sink principal and its matching speed can sharply increase the crushing ratio, output and content percentage of cubical product in final crushed material. 4. In the special circumstances such as irons was feed into the crushing chamber together with the materials and there is a jam in the crushing chamber, the hydraulic equipment could open the cover automatically, then the products could output successfully. It greatly reduced the trouble of stopping the machine to output the products artificially. Which makes the maintenance more convenient and with low cost. Standard
