[0002] Sand making machine is a kind of equipment widely used in medium and fine crushing of ores and rocks with medium hardness or below in sand making, mineral processing, cement, metallurgy, chemical industry, building materials and other industrial sectors. It usually includes structures such as movable roller, fixed roller, driving device, etc., wherein a crushing chamber is formed between the movable roller and the fixed roller. When crushing materials, the materials enter the crushing chamber through the feeding device and are crushed into preset specifications under the action of the movable roller and the fixed roller.
[0003] The existing sand making machine usually uses a cylindrical or funnel-shaped feeding device to align the material with the opening of the crushing chamber. If a cylindrical feeding barrel is used, when the diameter of the cylindrical ring is too large, it is easy to cause the material to fall out of the crushing chamber. When the diameter of the cylindrical ring is too small, it will affect the material feeding efficiency. When the funnel structure is used for feeding, the material will be affected by the slope, which will easily cause the material to collide with the grinding roller device and cause the material to fall out of the crushing chamber.
[0004] Therefore, it is urgent for technicians in this field to provide a grinding sand making machine with high feeding efficiency and ensuring that materials fall accurately into the crushing chamber. Summary of the invention
