Reclaimed material screening and breaking device and method for screening and breaking reclaimed materials

Abstract

The invention provides a reclaimed material screening and breaking device and a method for screening and breaking reclaimed materials. The reclaimed material screening and breaking device comprises a frame, a collecting unit, a screening unit, a breaking unit and a feeding unit, wherein the collecting unit is arranged on the frame, the screening unit is used for screening separating qualified materials from over-size materials of reclaimed materials, the breaking unit is used for breaking the over-size materials, the feeding unit is used for receiving the qualified materials discharged from the screening unit and the breaking unit, the screening unit is arranged below the collecting unit and provided with an opening, the breaking unit is disposed at the opening of the screening unit, and the feeding unit is arranged below the screening unit and the breaking unit. By the reclaimed material screening and breaking device, over-size reclaimed materials are directly broken into qualified reclaimed materials and then conveyed to a collection port of a lifter directly. Accordingly, the over-size reclaimed materials can be collected, transported and stored without transport vehicles, operation process is simplified, and production cost is reduced.

Description

technical field [0001] The invention relates to a screening and crushing device for recycled materials and a screening and crushing method thereof. Background technique [0002] After being used for a certain period of time, the overall performance of asphalt pavement will not meet the requirements of road use, but it still has a high value of use as a road material. Through pavement regeneration, it can meet the road performance requirements again, which can not only save a lot of material resources and funds, but also avoid environmental pollution, and realize the development mode of circular economy and sustainable development. [0003] The old pavement material obtained from asphalt pavement is called recycled material, which is usually obtained by milling and other methods. Recycled materials are usually crushed before use. The crushed recycled materials pass through the screening device between the collection belt and the feeding belt to screen out the oversized mater...
