Crusher with screening device for producing building waste recycled aggregates

Abstract

The invention discloses a crusher with a screening device for producing building waste recycled aggregates. A supporting plate is arranged in a case, a horizontal sliding groove is formed in the supporting plate, a horizontal straight gear is arranged on the inner side of the bottom of the left half part of the horizontal sliding groove, the horizontal straight gear is in meshed transmission witha circular gear, located in the horizontal sliding groove, the center of the back face of the circular gear is in transmission connection with a left roller cylinder through a rotating rod, the outersurface of a left roller is provided with a U-shaped wear-resistant plate, the two side plates of the U-shaped wear-resistant plate are fixed on the side wall of the left roller through screws, the front center of the circular gear is fixedly connected with a telescopic rod, the end of the telescopic rod is fixedly connected with an L-shaped handle, an arc-shaped wear-resistant plate is arranged on the surface of a right roller through a screw rod, and an inclined filter screen is arranged in the case, below the left roller and the right roller. According to the crusher, the gap between the left roller and the right roller can be adjusted through the position movement of the left roller, so that the crushing granularity can be adjusted; and the inclined filter screen can be used for screening crushed coarse aggregates and fine aggregates.

Description

technical field [0001] The invention relates to the technical field of a crusher with a screening device, in particular to a crusher with a screening device for producing recycled aggregate of construction waste. Background technique [0002] In my country, recycled aggregates from construction waste are mainly used to replace natural aggregates to prepare ordinary concrete or mortar, or as raw materials to produce non-sintered blocks or non-sintered bricks. The use of recycled aggregates from construction waste to partially or completely replace natural aggregates to prepare concrete and mortar has been successfully applied in many projects. The production of non-sintered blocks and non-sintered bricks from waste recycled aggregates can absorb more construction waste, and is an important way to recycle construction waste in my country, but it still has the following drawbacks in practical use: [0003] 1. In the production process of construction waste recycled aggregate, i...

AI Technical Summary

Problems solved by technology

[0003] 1. In the production process of construction waste recycled aggregate, it needs to be crushed first, and then screened. Obviously, this method consumes manpower, material resources and time. However, there is no one that combines crushing and screening. crushing device;

[0004] 2. Most of the existing crushers cannot adjust the crushing particle size, and even if they can, there are problems such as difficulty in particle size adjustment and small particle size adjustment range, which is inconvenient to use;

[0005] 3. The working principle of the crusher is mostly extrusion and impact. These two methods will cause greater wear and impact on the roller or liner used for crushing, which will cause serious wear and tear on the roller and liner.
