Production line for producing sand

Abstract

The invention relates to a production line for producing sand, which comprises a feeding machine, sand producing machines, a sand washer and sedimentation tanks, wherein the number of the sand producing machines is N, and N is an integral number not less than 1; feed inlets are formed in the sand producing machines; the feed inlets comprise stone inlets and water inlets; the feeding machine is respectively connected with the feed inlets of the N sand producing machines; the feed inlets of the N sand producing machines are respectively connected with the sedimentation tanks through pipelines; discharge outlets of the N sand producing machines are respectively connected with the sand washer; the sand washer is connected with the sedimentation tanks through pipelines. According to the invention, a cyclically utilized production line is formed, on one hand, the sand producing efficiency is improved, and the sand producing cost is reduced, and on the other hand, noise, dust and sewage pollution during the sand producing process are reduced, various intermediate products are enabled to be fully utilized, and the requirements of the present market are satisfied.

Description

technical field [0001] The invention relates to a sand making production line. Background technique [0002] As an essential component of building materials such as concrete and mortar, fine aggregate refers to aggregates with a particle size below 4.75 mm, commonly known as sand. According to the source of production, sand is divided into two types: natural sand and artificial sand. Natural sand is formed by natural weathering, water flow handling, sorting, and accumulation of rock particles with a particle size of less than 4.75mm, including river sand, lake sand, mountain sand and desalinated sea sand. Artificial sand is a general term for machine-made sand and mixed sand after soil removal treatment. The fine aggregates used in building materials in the past are basically natural sand, but natural sand resources are a local resource. With the increasing development of infrastructure, natural sand resources have gradually decreased in many areas of our country, and even...

Problems solved by technology

However, this type of production line is generally distributed outdoors, and the equipment such as belt conveyors and sand making machines are exposed outside without sealing, which will cause a large amount of dust emission during the sand making process and pollute the environment.

In order to control dust, humidification will be carried out during the sand making process. If the water flow rate is too large, the dust will flow out with the water, causing new water pollution
