Vibrating Feeder

A vibrating feeder is a very important machine which feeds bulk materials continuously and uniformly to crushers, screens, or other processing machines. Vibrating feeders make use of vibratory motion developed by electromagnetic drives or mechanical exciters. Vibrating feeders are used extensively in the mining, quarrying, cement, aggregate, recycling, and food and chemical processing lines. The principal function of a vibrating feeder is to feed with a smooth and even supply of raw material without stopping the operation due to arches blocked or clogging and improving the performance of downstream machinery in general. Polygonmachine vibrating feeders comprise heavy-duty construction, variable feeding capacities, and easy-maintenance aspects for a vast range of materials from powdery dusty to heavily large boulders. From varying hopper sizes to trough length as well as vibration facilities, our feeders are easily adaptable to meet project needs. From fixed plant installation to mobile processing plants, Polygonmachine vibrating feeders provide consistent operation as well as an efficient energy usage with minimum downtime and maximum production under harsh conditions.

Grizzly Feeder

Grizzly feeder is a heavy-duty vibrating feeder equipped with steel bars or grizzly sections and pre-screens and separates finer material before the crusher. The heavy-duty screening system removes unwanted fines and bypass material, thus reducing the load on the primary crusher. Grizzly feeders are usually mounted at the primary feed position in crushing circuits and are best suited for large rock and coarse material applications.

Polygonmachine creates high-performance heavy-duty grizzly feeders with abrasion resistance, severe impacts, and high feed rates. Our feeders are constructed using high-strength steel, which contains grizzly bars with adjustable screening aperture, allowing the operators to customize the screening gap. This improves the quality and quantity of material passing through and maximizes the crusher life as well. Polygonmachine grizzly feeders are a good option in mining, aggregate, and heavy-duty quarrying operations because of the robust construction and prudent engineering.

Vibrating Grizzly Feeder

Vibrating grizzly feeder (VGF) is an amalgamation of vibrating feeders and grizzly screens in a single unit.

It offers continuous material flow with pre-screening of fines and finer size material through grizzly bars. Two-stage system maximizes the efficiency of crushing plants on one end by providing protection for the crusher against unnecessary wear, and on the other end by attaining highest throughput. VGFs are extensively used in primary crushing circuits where screening and feeding simultaneously at high capacity are needed. Our vibrating grizzly feeders at Polygonmachine seek to optimize both feeding and material separation efficiency.

Our VGFs have variable vibration amplitudes and grizzly bar spacing, and therefore can be optimized to handle varying material sizes and material types. The feed trays have wear plates that handle abrasive loads, and the frame is designed to prevent vibration transmission to other equipment. Polygonmachine VGFs can be perfectly suited for fixed plant as well as mobile and semi-mobile uses with continuous and robust operation under tough conditions.

Prescreening Feeder

Prescreening feeder is a vital component of material preparation that removes fines and dirt from raw material before the primary crusher or screening plant. By stopping undersize material from entering downstream equipment in the early stages of operation, prescreening feeders make crushers more efficient, reduce downstream equipment wear, and improve final product quality. Prescreening feeders are particularly useful operations in which material contamination is a problem or where mixed feedstock from mining or excavation operations has to be handled.

Polygonmachine prescreening feeders feature high-speed vibratory systems and adjustable screening decks to maximize material separation.

Feeders are offered in numerous sizes and arrangements, from single-deck to double-deck screens, and can screen everything from clays to dry granular stone. Part of a portable plant or fixed installation, Polygonmachine’s prescreening feeders optimize overall plant efficiency and deliver cleaner feed for later processing stages. Our systems allow customers to save money, save energy, and achieve greater aggregate quality.

Vibratory Feeder

A vibratory feeder is a well-engineered machine which feeds material along a tray or trough by using vibrational energy. Unlike conventional mechanical feeders, vibratory feeders supply high-rate and highly controlled material feeding and are most suitable to fragile, small-sized, or finely granulated material. Vibratory feeders have wide use in packaging, chemical processing, food processing, electronic assembly, and light industrial processes where precision and consistency are critical.

At Polygonmachine, we provide vibratory feeders suitable for light-duty as well as heavy-duty applications.

Our feeders have intelligent controllers that allow variable frequency drives and amplitude modulation for adjusting feeds in real time.

Their quiet, maintenance-free operation and long life make them a perfect choice for round-the-clock processes that require non-stop flow. Polygonmachine vibratory feeders are heavy-duty but space-saving solutions that can potentially enhance material handling precision in a wide variety of industries, with added benefits of energy conservation and user ease.
