· Gyratory Crusher. Gyratory crushers are similar to cone crushers; they are frequently used in large-throughput primary crushing roles. Typically, they have larger capacities (up to 8000 tph) compared to jaw crushers (up to 1500 tph). Gyratory operate at a slower speed than cone crushers, typically in the range 85 to 105 rpm.

Answer (1 of 4): It is a common mistake to run an oil-lubricated crusher with contaminated lubricant (used oil, dirty oil). Ignoring the maintenance of the lubrication system, dust can invade the lubrication system and contaminate the lubricant. When the dirty oil …
How does it work in the process of crushing materials? First of all, the stone materials enter into the jaw crusher by the vibrating feeder for the primary crushing. After becoming smaller rock materials, they enter the compound crusher for the secondary crushing. After crushing in the compound crusher, it is necessary to screen processing.
in the primary mill. The aim was to reduce a portion of the feed material below critical size and generate more fines to decrease the load in the primary mill. Not all of the feed material was pre-crushed to allow for sufficient abrasion breakage in the primary mill. The SAG mill was converted to an AG mill and the ball mill was converted to a ...
How Does Ball Mill Work. Ball Mill Working principle When the ball mill works motor and speed reducer transmit torque force to big and small gears of ball mill so the barrel the barrel rotates Steel balls or other grinding media in the barrel are lifted to a certain height and fall down freely so materials in the barrel are impacted.

We can ...
The third step in crushing, or tertiary reduction, depends upon what is required. Two-inch or smaller pieces from the secondary crushers may be fed direct to stamps, rod mills, or ball mills, but it is more usual to use a third dry crusher to reduce the ore to ½- or 5/8-in. size before wet crushing, particularly in the case of ball milling.
The dry feed of a ball mill circuit is 300 t/h. The power at the pinion of the ball mill is 1800 kW. F80 = 80% passing size of the circuit feed, in microns = 2500 um. P80 = 80% passing size of the circuit product, in microns = 225 um Solution. Work Input (Energy input): W= (1800 kw)/ 300 t/h=6.0 kwh/t. Then. WI = Work Index of this circuit
Since there are not that many small SAG mill operations of under 2000 TPD, and most sub-2000 TPD mills are built with rod mills and/or ball mills only; the upstream crusher plant needs to have sufficient crushing power to provide a P80 to grinding of typically <1.5″ (40 mm) and often as finely crushed as <3/8″ (9 mm).
8, mill operation, the main bearing lubricating oil temperature does not exceed 55 . 9, mill normal operation, the drive bearings and gearbox temperature does not exceed 55, a maximum of 60 . 10, main bearing serious wear and tear should be replaced . 11, lattice -type ball mill Grate Plate Welding can no longer wear to be replaced .
