Rolling grinding type continuous sand screening device for buildings

Abstract

The invention discloses a rolling grinding type continuous sand screening device for buildings. The device comprises a sand screening box, an outer filter screen cylinder, a grinding cylinder, an inner filter screen cylinder, a rotating shaft, grinding balls, pushing spiral blades and grinding rollers. The sand screening box is installed on a support frame, the rotating shaft is horizontally erected in the middle of the sand screening box, the grinding rollers are welded in the middle of the rotating shaft, the pushing spiral blades are welded on the rotating shaft and located on the other sides of the grinding rollers, the rotating shaft is sleeved with the inner filter screen cylinder, a grinding cylinder is arranged in the middle of the inner filter screen cylinder, and an outer filterscreen cylinder is fixedly connected to the exterior of the inner filter screen cylinder. Screening, grinding and ball milling of building sand particles are achieved till the sand particles are completely screened out, finally the sand particles are discharged from a discharge hopper to be used in building construction, operation is convenient and fast, the screening efficiency is high, meanwhile, the grinding and ball milling effects are quite good, it is ensured that the building sand particles can be sufficiently applied to building construction, and the problem that traditional large-particle-size sand particles cannot be used in the buildings after being screened out is avoided.

Description

technical field [0001] The invention relates to the technical field of construction equipment, in particular to a rolling grinding type continuous sand screening device for construction. Background technique [0002] During the construction of the construction site, sand is used, and the sand cannot be used directly when it is bought back. The sand needs to be sieved. The net is only limited to artificial, the efficiency of artificial sand screening is low, the labor intensity is high and cannot keep up with the fast-paced construction, so it has to take up more manpower and increase the construction cost; The sand screening treatment can meet the requirements, otherwise it will affect the engineering quality of the construction. [0003] There are many sand screening devices in construction sites or other construction fields, and professional sand screening machines are rarely used for sand screening in construction sites. Such sand screening machines are expensive and cos...
