Technical Field

[0001] The utility model belongs to the technical field of concrete raw material grinding, and particularly relates to a grinding device for producing concrete raw materials. Background Art

[0002] Concrete (also known as artificial stone) is a general term for composite materials configured by gel materials, aggregates and water in appropriate proportions and hardened after a certain period of time. It is the most widely used artificial civil engineering material in the world. Concrete has the characteristics of rich raw materials, low price and simple production process, which make it widely used. It can be applied not only in various civil engineering projects, but also in shipbuilding, mechanical industry, ocean development, geothermal engineering, etc. Concrete is also an important material.

[0003] The grinding of concrete raw materials is to increase the surface area of the raw materials and improve their activity. The fineness of the raw materials has an important impact on the strength and hardening time of cement. At present, due to the different sizes of the raw materials, it is easy to cause uneven grinding. Secondly, dust will fly during the grinding process, which affects the health of the staff.

[0004] Therefore, in view of the deficiencies of the above solutions in actual production and implementation, they are corrected and improved. At the same time, in the spirit of pursuing excellence and with the assistance of professional knowledge and experience, and after various ingenious ideas and tests, the present utility model is created. A grinding device for producing concrete raw materials is provided to solve the above problems. Content of the Utility Model

[0012] As a preferred embodiment of a grinding device for concrete raw materials, the top surface of the bevel pulley is inclined towards the center.

[0013] With the above scheme, the bevel pulley is beneficial for the raw materials to better contact the cutter head body. Since the top surface of the bevel pulley is inclined, the raw materials will be continuously guided towards the cutter head body. The high-speed moving cutter head body is used to grind the raw materials, and the raw materials passing through the cutter head body will be refined and thus fall into the aggregate shell.

Secondly, the process of the bevel pulley driving the raw materials to move is conducive to better contacting the cutter head body and the convex tooth part to improve the grinding efficiency.

[0016] As a preferred embodiment of a grinding device for concrete raw materials, there is a gap between the cutter head body and the bevel pulley.

[0017] After adopting the above technical scheme, the beneficial effects of the present utility model are as follows: This device has a good grinding effect. The bevel pulley at the bottom of the grinding shell can drive the raw materials to move continuously under the action of transmission, which can avoid the accumulation and blockage of raw materials at a certain place.
