Stone crushing and screening device for hydraulic engineering

Abstract

The invention relates to a stone crushing and screening device for hydraulic engineering. The device comprises a pneumatic impact chamber, a crushing chamber, a screening device and a water purifyingdevice. Each chamber of the whole device is provided for screening during crushing and recycling water in the treatment process to prevent environmental harm caused by production. Through arrangementof a water spraying screening mode, the efficient screening of crushed stones is achieved.

Description

technical field [0001] The invention belongs to the field of water conservancy engineering, in particular to a stone crushing and screening device for water conservancy engineering. Background technique [0002] In water conservancy engineering operations, the requirements for the particle size of stones are relatively high. The existing methods mainly use different vibrating screens to screen stone particles of different sizes after uniform crushing. That is to say, crushing and screening are different processes. , thereby increasing transportation costs. Moreover, the existing crushing methods cannot finely control the particle size of the final crushed stone particles. If as much as possible can be crushed to the required particle size during the crushing process, the scrap rate will be greatly reduced, and the cost can be greatly saved. [0003] In the stone crushing process of water conservancy projects, a large amount of dust will generally be generated. The existing ...

[0002] In water conservancy engineering operations, the requirements for the particle size of stones are relatively high. The existing methods mainly use different vibrating screens to screen stone particles of different sizes after uniform crushing. That is to say, crushing and screening are different processes. , thus increasing the transportation cost

Moreover, the existing crushing methods cannot finely control the particle size of the final crushed stone particles. If the crushing process can be crushed as much as possible to the required particle size, the scrap rate will be greatly reduced, and the cost can be greatly saved.

[0003] In the stone crushing process of water conservancy projects, a large amount of dust will generally be generated. The existing way to remove dust is only to install an atomization device, but the atomization device will consume a lot of water resources, and direct discharge will cause certain damage to the water body.
