Two-Mass screens substantially improve productivity and enable major process debottlenecking
As mine size and tonnage grew exponentially over the recent decade, material handling/processing equipment also increased in size resulting in 400 MT haul trucks, 2000 KW crushers, 12 M SAG/AG mills, 8.5 M ball mills, 3000 M3 flotation cells, and 12.5 MW HPGR’s becoming standards in the global mining industry. And, further process capacity growth is expected.
Other critical equipment, including vibrating screens, had to increase in size to handle tonnages and feed rates upwards of 3500 MTPH. And, there are circuits under design that will require screening feed rates of 4500 MTPH.
It is not uncommon for hi-volume, hi-value comminution circuits to operate significantly below their design tonnages due to underperforming Brute Force Vibrating Screens. General Kinematics® Proprietary STM-SCREEN™ Technology operates beyond the finite design limitations of traditional Brute Force screens. They are designed and constructed to process higher tonnages, at circuit design efficiencies, reliably (with only routine maintenance), and operate for years beyond what has become acceptable in the industry.
About General Kinematics
General Kinematics Corporation, incorporated in 1960, was established to market, design, and custom fabricate innovative vibratory materials handling and processing equipment. Today the company is one of the world’s largest suppliers of vibratory processing equipment, having held more than 200 worldwide patents, and is acknowledged as a major contributor to the technical advancement of vibrating equipment design and application. General Kinematics serves a worldwide customer base through a network of engineering-oriented independent sales representatives who cover major industrial markets throughout the United States. International markets are serviced from subsidiary operations and through a combination of representatives, licensed manufacturers, and strategic alliances with leading industry-specific organizations in other strategic locations. Today, over 50,000 General Kinematics units have been installed globally. As new process and efficiency challenges emerge, General Kinematics is uniquely qualified to address these needs with advanced technology, innovative engineering, new materials, and manufacturing techniques applied to improving customer productivity and profitability. Today, GK knows no limit in our ability to provide a broad level of engineering support and capacity that other companies cannot offer. We bring a 360-degree view to the whole process picture, often supplying engineering resources our customers do not have, or do not wish to fund internally.
