The environmental protection sand washing sewage treatment project with an hourly capacity of 300 tonnes built by Henan Liming Heavy Industry for a certain environmental protection building materials enterprise in Ningbo, Zhejiang Province, has been fully installed and successfully tested, and then entered the formal production stage. The project from the design of the programme, the composition and configuration of the system, the selection of models, dust removal measures, sewage treatment and other stages of the process design are completed independently by the technical department of Henan Liming Heavy Industry, the customer production experience is very good!

Ningbo, Zhejiang Province, 300 tonnes per hour of environmentally friendly sand washing production line raw materials for cobblestone sand, from the crushing system, screening system, to the sand system, sand washing system, sewage treatment, each link adopts a fully enclosed production, dust collection pipeline is arranged in the system of each dust point, to avoid dust spillage, to achieve clean and dust-free production.

Project Features

High capacity and strong cleaning power

The capacity of the three-wheeled sand washing machine can reach 300 tonnes/hour, and the strong water rushing can effectively remove the dust on the surface of the sand and gravel, and at the same time destroy the water vapour layer on the surface of the encapsulated sand and gravel, and dry it quickly to improve the quality of the finished material; through the fine sand recycling device, the fine sand flowing away can be recycled effectively, with high economic benefits.

No dust, no waste water, environmentally friendly production

Dust collection pipes are covered at all dusty points of the project, and the whole site is clean and environmentally friendly; sand washing sewage will be concentrated in the sedimentation tank, and by adding flocculants to the sewage, the mud and dirt will be quickly coagulated and precipitated, and the sewage will be preliminarily separated - the clear water will be returned back to the clear water tank through the pipes for recycling, and the mud will need to be cleaned up regularly after it is sunk, and it will be available to be used to burn bricks, It can be used to burn bricks, return to the field to plant crops, be used to plant flowers in the park, and be used as filler for road base, etc., so as to realise the best use of things and turn waste into treasure.

Scientific and reasonable, compact layout, intelligent and advanced

Reasonable use of terrain advantages and environmental advantages, integration of resources on-site, according to the nature of raw materials and processing needs of scientific configuration of production line equipment and models, the application of intelligent monitoring operation, 360 ° all-round monitoring of the production line in and out of the material and equipment operation, emergency shutdown troubleshooting, to protect the equipment from being damaged, intelligent and advanced.
