Gyradisc Crusher operating-cost-per-ton of sand includes liners, maintenance and power draw. The liner cost is related to the abrasive characteristics of the material being crushed and the surface moisture. Average liner costs are between $.03 and $.06 per ton of sand. Proper maintenance, excluding liners, will result in costs not exceeding $.01 per ton. Power consumption will be in the area of 3 kwh per ton of sand. The following charts show typical sand circuit gradations for limestone, gravel, and granite.

European type jaw crusher offers lowest operating costs for wheeled & track-mobile units

a@b.com (admin9999) — Wed, 15 Feb 2012 00:20:06 +0800

Delivering lower operating costs to operators of wheeled or track-mobile units, the European type jaw crusher is the result of advanced jaw crusher technology which increases uptime and production capacity, while streamlining operation and maintenance—and ensuring greater safety. At the heart of the low-cost operation of the H2550 is its unique hydraulic toggle system, which features a heavy-duty hydraulic cylinder that is custom-engineered for crushing applications. The unit’s innovative hydraulic adjustment, relief and clearing systems eliminate costly downtime and prevent component damage, while also protecting workers from the risks typically associated with the operation and maintenance of older jaw crusher models. Ideally suited for the portable contractor, the FEA-designed H2550 is engineered as a lowprofile unit with foot mounts located at mid level; and a sculpted main frame which reduces overall weight, yet offers optimal strength and reliability.

Keep Production on Track - Track mounted crusher

a@b.com (admin9999) — Sun, 29 Jan 2012 20:56:59 +0800

The use of mobile crushing and screening plants in rock processing has arguably been slower to catch on in the United States than in other parts of the world, but it continues to be a growing trend.

“In 1999, we went from using haul trucks to using a track mounted primary horizontal shaft impact crusher at the face,” says Jon Pechacek, quarry manager for Aggregate Industries’ Larson Quarry near Minneapolis. “We then convey the material to a surge pile for the secondary crusher, which is a stationary HSI crusher.”

how to measure material hardness and choice right crusher

a@b.com (admin9999) — Sat, 14 Jan 2012 20:16:34 +0800

how to measure material hardness and choice right crusher?

1. Moh’s hardness
It is a standard to measure material or mineral ore hardness proposed by Germany mineralogist Mohs. He uses pyramid shape diamond needle to carve on the surface of mineral ore, which is called scarification. The carved depth is used to measure the ore hardness. Moh’s unit is level such as f=2 means the hardness of ore is level 2. The Moh’s hardness is not the absolute ore harness value but a number represent ore harness according to harness order.

Track-mounted crusher moves producers forward with improved versatility and efficiency

a@b.com (admin9999) — Thu, 12 Jan 2012 00:06:44 +0800

Mobile equipment just makes good sense. This rings particularly true for producers who utilize crushing and screening equipment because, in many cases, it is easier to take the crushing plant to the material--instead of the other way around. As a result of this fact of life, many producers are choosing to operate track-mounted equipment that can go where the work is.
