Problems solved by technology

However, the existing stone crushing device cannot crush the stones into a certain particle size range, and can only obtain stones with specific particle sizes through conventional crushing and screening.
This not only greatly increases the cost, but also causes a lot of waste of stone materials.

Embodiment 1

[0030] A precise crushing device for building stones, such as figure 1 As shown, it includes a preheating chamber, an ultrasonic chamber, an impact chamber, a coarse crushing chamber, the first vibrating screen component, a stone grinding chamber, a fine crushing chamber and a stone collection component. The particle size of the required stone particles set in this embodiment is 35mm, and the settling of the powder is less than 8mm.

[0031] The preheating chamber includes a main stone entrance and a stone exit. The preheating chamber is filled with hot water, and an electric heating wire for supplementary heating of the water body is provided on the inner wall of the preheating chamber. The main stone entrance is used to Stones that need to be broken are added to the preheating chamber (not shown in the figure).

[0032]The ultrasonic chamber includes an ultrasonic chamber inlet, an ultrasonic chamber outlet, a movable support plate, ultrasonic tines, an ultrasonic generator...

Abstract

The invention relates to an accurate stone crushing device for building. The accurate stone crushing device for building comprises a preheating chamber, an ultrasound chamber, an impact chamber, a coarse crushing chamber, a first vibrating screen part, a stone grinding chamber, a fine crushing chamber and a stone material collection part. Through specific setting of the various parts, crushing ofthe maximum accurate grain size of stones is realized, and the subsequent screening cost is reduced.

Description

technical field [0001] The invention belongs to the field of construction equipment, and in particular relates to a precise crushing device for construction stones. Background technique [0002] In the construction process of road construction and infrastructure construction, the stability of stone particle size is very high, and the particle size of stone particles is required to be within a specific range, and the smaller the upper and lower deviations, the better. However, the existing stone crushing device cannot crush the stones into a certain particle size range, and can only obtain stones with specific particle sizes after conventional crushing and screening. This not only greatly increases the cost, but also causes a lot of waste of stone. If the stone crushing device can be set as a device with a stone material acquisition rate of more than 80% within the effective particle size range, then the cost of subsequent screening (including time cost, labor cost, etc.) R...
