The invention discloses a crusher, an anvil device, an anvil piece of the anvil device, and a mineral production line, and further discloses a material crushing method. The crusher comprises a crushing and shaping structure with material impacting parts (10) and material liner forming parts (11); and the relative position relationship between each material impacting part (10) and at least one material liner forming part (11) is that a material impacted by the material impacting part (10) can be at least partially turned and impacted to a material liner layer (4) of the corresponding material liner forming part (11), so that sequential impact of the material to the material impacting parts (10) and the material liner layers (4) is realized continuously. Due to the ingenious sequential impact manner, not only is the 'material and anvil mixed beating' crushing mode realized in deed, but also the crushing efficiency is high, the shape of crushed particles is good, and the porosity of the crushed material is significantly higher than that of a material crushed with the conventional crusher.

The utility model discloses a sand making machine capable of improving production capacity. The sand making machine comprises a cutter bar and a sand cavity and is characterized in that the length of the cutter bar is 400-600mm, a lower cavity of the sand cavity is in a shape of a cone, and the length of the sand cavity is matched with that of the cutter bar. The lengths of the cutter bar and the sand cavity are lengthened so that strike, friction and grinding and crush rate borne of materials in a sand making cavity are improved, sand making efficiency is high, acceptability is high, and production capacity is improved. The lower cavity of the sand making machine can be changed into the shape of the cone, manufacture materials of the sand making machine are saved, inner cavity spaces of the sand making machine can be sufficiently and reasonably used, a sand receiving surface of a sand receiving hopper can be reduced during sand receiving, simultaneously manufacture materials of the sand receiving hopper can be saved, and production cost is reduced.
