Mining

Artisanal miners can be found around the world outnumbering the industrial mining population 14 to 1. From panning for gold in a stream to operating their own claim with their own elaborate processing system. Whether it is done as a hobby or a full-time job one thing is for certain: artisanal mining is a way […]

A Canadian mine was dealing with the effects of an unreliable screen positioned at the discharge end of a Sag Mill. In addition to creating downtime, the brute-force screen was not processing the desired load of wet copper ore. Understanding the process and the level of reliability that the process needed, General Kinematics’ talented subject […]

Challenge General Kinematics was given a challenge. A screen for sizing limestone was sitting over 100 feet in the air atop a silo. Due to the difficult access point, it needed to be replaced with a reliable screen that did not get jammed or need maintenance often. The inquiring company sent their material to GK […]

Challenge A major mine in South Central China was in the market for two new screens for iron ore processing. The vibrating screens they owned had been installed two years previously by another manufacturer. Since installation, the screens had experienced severe resonance issues and were literally shaking apart. As the amplitude would increase to process […]

Challenge A Canadian gold mine was looking to partner with a vendor that could meet their standards for optimizing their process and a machine capable of handling their increased production volume, with lower overall operating cost. They needed a unit that could accomplish the grueling task of sorting their extracted materials to a size of […]

Challenge In a process used to make quicklime, a substance used in cleaning solutions, paper mills, and the food industry among other applications, limestone is mined from calcium carbonate deposits. Once the soon-to-be quicklime limestone has been extracted from the ground it is sorted by a preliminary screen to be a maximum size of 6”. […]

In Process Solution Challenge A metals and mining company needed to automate the processing of their liquid waste material stream – a mixture of water with base and semi-precious metals. Their existing batch process was inefficient as it required shutting off flow into the chamber to recharge iron into their process. Additionally, the time required […]

On the Hunt for a Screening Material Solution Challenge A customer had an existing system that used a grizzly section running perpendicular to the material flow stream. The grizzly section of this stationary unit constantly clogged up and needed to be cleaned manually by the facilities operations team. If it was not kept clean all […]

Challenge Potash is a necessary fertilizer to the world, and is used to grow corn, wheat, soybeans, potatoes and many other crops. Today, Potash is mostly found in deep shaft mines as much as 4,400 feet (1,400 m) underground. Herein lies one of the main challenges in mining these salts: tight underground quarters leave little […]

Challenge
Customer wanted to replace an existing vibrating screen due to frequent mechanical failure issues. Existing screen technology utilized the traditional brute force drive with large shafts, bearings, and motors. In the application, brute force screen technology typically had a useable life of around 1 year before mechanical failure occurred. The new screen needed to fit into the same area of the plant and run without issues.
