Description

Technical Field

[0001] This utility model relates to the field of roller crusher technology, specifically to a roller crusher material receiving device. Background Technology

[0002] Roll crushers are devices that crush materials through the squeezing, shearing, or grinding action between a pair of rotating rollers, and they continue to play an important role in modern industry. They are characterized by their simple structure, convenient operation, and uniform output, making them particularly suitable for medium and fine crushing of materials with medium hardness or lower. With continuous technological advancements, they still have broad application prospects in mining, building materials, metallurgy, environmental protection, and other fields.

[0003] When using a roller crusher, continuous crushing operations can cause material to accumulate at the bottom. If the material cannot be fed out evenly, the accumulated material may prevent newly entering raw materials from making full contact with the rollers, causing a "stalling" phenomenon. This means that although the equipment is still running, it will actually affect the crushing capacity and subsequent processing stages. Utility Model Content
