Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of aluminium slag ball recovery, and specifically relates to a crushing and screening equipment. BACKGROUND

[0002] After the aluminium slag ball is crushed, its surface area is greatly increased, which helps to melt faster in the subsequent smelting process. In contrast, large pieces of aluminium slag ball that are not crushed need longer time and higher temperature to reach a completely melted state, which not only increases energy consumption, but also increases time cost. Through crushing treatment, these costs can be effectively reduced and smelting efficiency can be improved

[0003] The existing patent No. CN211303209U discloses a crushing and screening device for building waste recovery, which includes a second limiting plate and a crushing shell. When using, the building waste is poured into the crushing shell above the screening plate. The worker can control the first limiting plate and the second limiting plate to move a corresponding distance in the crushing shell according to the amount of waste, so as to form a space between the first limiting plate, the second limiting plate and the inner wall of the crushing shell for the crushing roller to crush the waste, thereby improving the crushing efficiency. Then the worker starts the driving motor to make the crushing roller rotate, and then pours the waste into the crushing shell through the feeding port. The waste is crushed by the crushing roller, and the small waste after crushing falls below the screening plate. The larger waste that is not crushed is intercepted by the screening plate and slides to the first limiting plate. When the crushing work is about to be completed, the first limiting plate is moved upward by moving the L-shaped support plate, so that the waste intercepted by the screening plate slides through the communication hole into the receiving pocket. Then, according to the amount of waste in the receiving pocket, the first limiting plate and the second limiting plate are controlled to move a suitable distance in the crushing shell, and the waste in the receiving pocket is poured into the crushing shell through the feeding pipe for crushing.

[0004] The above device needs to screen the thickness of the waste when crushing the waste, relying on a group of screening plates for screening. The falling waste may be stuck on the screening plate, affecting the screening and being difficult to clean. To solve the above problems, a crushing and screening equipment is provided.
