Grizzly screens are typically constructed by welding steel rails, rods, or bars into grids with a specific pattern. The selection of rails can vary in size, ranging from about 7.4 kg/m to approximately 225 kg/m. These rails generally run parallel to each other along the entire length of the screening surface. The spacing between the rails typically range from 5 to 200 mm. To facilitate the smooth flow of materials, the openings are often tapered, with the top being wider than the bottom. Heavy-duty grizzly bars are commonly cast from manganese steel and feature double tapers. These grizzly screens are designed to receive large lumps of ore from sources such as railroad wagons, tipper cars, and other bulk material handling systems that discharge materials from considerable heights. As a result, they are constructed to be exceptionally robust to withstand the impact and handling of heavy materials.

Various minerals are found in nature either in a dispersed state, where they exist as separate entities, such as native gold particles in silica rock, or in a combined form, where they are bound within a host rock. Dry material separations using screens and sieves are typically attempted down to particle sizes of about 75 microns. Finer materials have a tendency to block the sieve openings. In such cases, screening in the presence of water can be helpful. Separating even finer-sized materials becomes challenging using traditional sieves. For such fine materials, alternative processes like classification need to be employed. Screen Types: * Grizzly Screens * Inclined Vibrating Screens * Horizontal Vibrating Screens * Dewatering Vibrating Screens Novelty Structures supplies various type of Screens for Mineral Processing Plants.

Mobile crushers are mounted on a self-propelled steel platform equipped with wheels, crawlers, or pneumatic pads for movement. The platform incorporates all necessary auxiliary equipment and subsystems for crusher operation. They operate independently on the mine floor. Placed at the working face, the crusher minimizes the need for truck or front-end loader transport, with planned moves occurring between one day and one week. Installation of mobile crushing plants is advantageous under specific conditions; * A clear and undisturbed geological situation, * Straight and long benches for shiftable face conveyor installation, * Long-term mine planning for various conveyors. The benefits of fully-mobile crushers include * Elimination of truck transport * Reduced personnel requirements * Avoidance of high truck maintenance costs * Decreased mine traffic * Overall improvement in mine safety.
