Ladder sand making system

Abstract

The invention relates to a step type sand making system. The step type sand making system comprises a feed hopper, a bucket elevator, a sand making machine, a vibrating screen, a grading optimization machine, a powder concentrator, a dust remover, a humidifier, a sand output belt conveyor and an electric device control system and is characterized in that the sand making machine, the vibrating screen, the grading optimization machine, the powder concentrator, the dust remover, the humidifier and the electric device control system are distributed in a step mode from top to bottom. The step type sand making system has the beneficial effects that the structure is reasonable, the product quality is high, grading is continuous, the fineness modulus is adjustable, measures can be taken according to local conditions, the building cost can be lowered, equipment installation is convenient, automatic control can be realized, the number of needed operating personnel is small, raw material can be operated from high to low in the processing process, the electricity consumption is small, the product cost is lowered, and the product transportation is convenient.

Description

Technical field: [0001] The invention relates to a sand making system, in particular to a stepped sand making system. Background technique: [0002] Manufactured sand is rock particles that are mined by removing soil, mechanically crushed, and screened, with a nominal particle size of less than 5mm. The machine-made sand production line is divided into two processes: wet sand making and dry sand making. For the dry sand production line, the basic process takes the raw material below 40mm as an example: the aggregate of 0-40mm is transported to the vertical impact crusher for crushing through the suspension feeder and the belt conveyor, and the crushed material is sent to a The two-layer vibrating sieve is screened, and the material larger than 5mm is returned to the impact crusher for re-crushing, forming a closed loop; the material of 3-5mm can be partially discharged into finished products according to the discharge requirements, and part of it can be returned to the impa...

AI Technical Summary

Problems solved by technology

This kind of traditional sand making system needs to be set up in a relatively open place with a flat ground. Generally, the mountain is steep and has a certain slope. It is difficult to build a flat ground, the construction amount is large, and the construction period is long.

If the sand making plant is built at a high place, it is close to the raw materials, but it is not conducive to product transportation; if it is built at a low place, it is convenient for product transportation, but it is far away from the raw materials

Regardless of whether it is built in a low place or a high place, the materials need to be lifted many times during the entire production process, resulting in large power consumption and high product costs
