How Does A Sand Washing Plant Work?

The sand-washing plant refers to the washing process of artificial sand (including natural sand). It consists of a jaw crusher, a sand-making machine, a sand-washing machine, and belt conveyors. The vibrating feeder evenly transports the materials to the jaw crusher for coarse crushing. The coarse crushed material is sent to the sand-making machine by a belt conveyor for further crushing. Finally, the fine material enters a vibrating screen for screening. Material that meets the particle size requirements enters the sand washing machine for cleaning.  After cleaning, it is output by the final product conveyor belt as the final product. Materials that do not meet the particle size requirements of the final product are returned from the vibrating screen to the sand-making machine for reprocessing, forming a closed loop with multiple cycles.

Applicable industries

It is suitable for sand and gravel cleaning industries such as mining, metallurgy, building materials, transportation, water conservancy and hydropower, concrete mixing plants, etc.

Equipment configuration for sand washing production line.

Sand washing machine, stone crusher, classifying equipment, vibrating screen, belt conveyor, etc.

Introduction to the sand washing plant

The sand washing equipment plant is also known as the sand washing production line, sand washing plant, etc. It is a wet sand and gravel washing production line in machine-made sand production lines. The water-washing sand equipment is mainly used to clean various sand and gravel dust, stones, and other impurities in river sand, ground sand, weathered sand, etc. The washed sand and gravel products have wide applications in sand yards, mixing plants, and various engineering projects to assist in the smooth development of sand-making processes.

Complete set of sand washing plant configuration

In addition to the sand-washing equipment, the entire sand-washing production line includes crushing equipment, sand-making equipment, screening equipment, feeding equipment, and conveying equipment.

Feeding equipment: For uniform and continuous feeding of crushing equipment, it is common to use vibrating feeders under the warehouse and vibrating feeders outside the warehouse.

Coarse crushing equipment: For coarse crushing of large stones usually use jaw crushers and heavy hammer crushers.

Medium and fine crushing equipment: secondary crushing/shaping crushing, often using impact crushers, cone crushers, etc.

Sand-making equipment: Fine sand-making, often using double rotor sand-making machines, impact sand-making machines, etc.

Screening equipment: Screen different specifications of sand and gravel, often using circular vibrating screens, linear vibrating screens, vibrating screens, etc.

Sand washing equipment: sand washing machines, and stone cleaning equipment, improve material utilization, save resources, and are environmentally friendly.

Process flow of sand washing plant

The raw materials enter the crushing equipment through a vibrating feeder.

After coarse crushing, it enters the secondary crushing (shaping) equipment for secondary crushing.

Crushed stones enters the vibrating screen for screening.

Enter the sand-making equipment for sand production, and return to the intermediate crushing equipment for secondary crushing if it does not meet the requirements.

After sand making, the stone material passes through the vibrating screen again. Qualified ones enter the sand washing machine for washing, while unqualified ones return to the sand-making machine for sand-making again.

Characteristics and advantages

Investment is only one-third to one-fifth of the conventional production line with the same processing capacity.

The production cost per ton of sand and gravel is only one-third to one-fourth of conventional production lines.

The production automation level is high, with less than three production personnel per shift.

Investment payback period is short, usually taking three months to recover the investment.

Performance Introduction

The sand washing plant has a high degree of automation, low operating costs, high crushing rate, energy saving, large output, low pollution, and easy maintenance. The final machine sand meets the standards of building sand, with uniform particle size, good particle shape, and reasonable grading.

The equipment configuration of the sand washing plant is mainly determined based on the customer’s specifications, output, and usage of the stone materials. We provide a one-stop service for pre-sales, sales, and after-sales, and configure the process according to the customer’s production site, striving to achieve a reasonable and economical production line for the customer.

What is the prospect of the sand-washing plant?

After processing such as washing and grading, machine-made sand can be used in industrial fields such as construction, highways, railways, water conservancy, and bridges. It has irreplaceable value in the market, especially with the gradual scarcity of sand in recent years, and washed sand has received more attention.

How do we invest in an environmentally friendly sand-washing plant factory? 

Environmental sand washing plants are designed to address major pollution issues such as dust, noise, and sewage pollution.

Choose environmentally friendly equipment: Choose water-washing sand equipment with strong sealing performance to fundamentally control dust leakage, and then equip it with dust collectors and enclosed conveyor belts for more significant environmental protection effects.

Suppress noise pollution: Equipped with noise reduction and sound collection devices, build enclosed factories to prevent noise transmission and control pollution.

Clean sewage pollution: Constructing sedimentation tanks to settle sand-washing wastewater, recycling water resources, settling sludge, waste soil, etc.
