XY Heavy Duty Grizzly Feeder Uniform Feeding Pre Screening High Output Feeder

The XY Heavy-duty Grizzly Feeder is an optimized and improved model with a specially designed grizzly developed by Xinyida Machinery. Based on in-depth research of vibration principles and mechanical structures, combined with years of successful experience in feeder manufacturing, it is engineered to solve the problem that excessive mud in raw materials negatively affects crushing. This machine provides uniform feeding of large-sized materials before coarse crushing, while the grizzly effectively removes fine materials such as mud and achieves pre-screening, thus boosting coarse crushing capacity. Adopting a heavy-duty structure with shaft eccentricity and block eccentricity combined, the feeder withstands impact from falling large materials and delivers high processing capacity.

The feeder features a unique three-stage grizzly design that effectively prevents feeding blockages, better pre-screens out mud and small-sized sand and gravel, and improves the crushing efficiency of the entire production line. Equipped with a variable frequency speed-regulating motor, it allows convenient and quick adjustment and control of feeding flow, making feeding more uniform, accurate, and stable, with smoother start-up and easier operation. The side plates are made of high-yield strength steel plates with reinforced steel plates at the exciter area to ensure overall strength. The screen body adopts Huck rivets and a hemming process, eliminating stress concentration caused by welding and preventing frame loosening and deformation under long-term operation, giving the feeder higher fatigue strength and outstanding durability.

The exciting force is generated jointly by shaft eccentricity and eccentric blocks rotating on the eccentric shaft, delivering stronger vibration force, smoother operation, and longer service life. The whole screen body is processed on a gantry boring and milling machine for double-side milling and boring, ensuring perfect alignment and concentricity for exciter assembly. The bearing housings are made of special alloy steel, avoiding the high wear that causes bearing outer race rotation in conventional materials. The bearings adopt an advanced thin oil lubrication system with a special labyrinth seal design to prevent oil leakage, more than doubling bearing service life.
