Description

Technical Field

[0001] This utility model relates to the field of foundry sand grinding technology, specifically a foundry sand grinding machine for casting. Background Technology

[0002] Foundry sand is a granular refractory material used in foundry production to prepare molding sand and core sand. Natural foundry sand requires crushing stones during processing, and then grinding the crushed stones into fine granules using a grinder.

[0003] A search revealed that patent application number 202022449220.6 discloses a grinding machine for processing foundry sand, including a support plate. Support legs are fixedly connected to the four corners of the lower surface of the support plate, and a first concave plate is fixedly connected to the upper surface of the support plate. An electric push rod is fixedly connected to the top inner wall of the first concave plate. This grinding machine grinds foundry sand by rotating a grinding column and a grinding barrel in opposite directions, enabling the device to grind foundry sand of different volumes relatively evenly, preventing large volumes of foundry sand from flowing out of the grinding barrel, thus ensuring the grinding quality of the foundry sand. The electric push rod drives the grinding column, increasing or decreasing the gap between the outer surface of the grinding column and the inner wall of the grinding barrel, allowing adjustment of the grinding volume of the foundry sand, facilitating operation and ensuring the practicality of the device.

[0004] The aforementioned application document adjusts the spacing of the grinding tanks by setting up the upper and lower adjustment components to grind the raw materials between them accordingly. However, since it is an integral bucket shape, the spacing between the upper and lower positions is the same, which means that only the raw materials can be ground individually, resulting in limited grinding effect.

[0005] Therefore, we propose a foundry sand grinding machine for casting. Utility Model Content
