No.6 Fine Sand Recycle System

In the past few years, we improve core technical, select new processing methods and absorb different sites working situation, and successfully make No.6 sand recycling system as our LZZG brand. It is also called as “dewatering type sand recycling system”.

LZZG series introduced products to absorb foreign advanced technology, and designed combined with sand field actual situation. It can effectively reduce the loss amounts of fine material; solve problems of end product such as relatively high fineness modulus and relatively low stone powder content. The fine material can be recycled as high as 95%, with incomparable technical and economic advantages.

Details Introduction

Fines recovery units is a combination of dewatering screen and hydrocyclone that is specifically developed integrates dewatering, screening and fine material recovery on the basis of the original recycling machine, and achieves the effect of multi-purpose machine. Fines recovery unit is generally directly used at the rear of sand washer, dewatering screen further dehydrates the finished material of sand washing machine, and recovery system effectively extracts and recovers the fines in tail water overflowed by sand washing machine to realize the coarse and fine sand centralized dehydration and recovery.

Working principle
About No.6 sand recycling system, we still choose polyurethane screen as its main screening part, and add recycling part on TS dewatering screen.
Sand after sand washer is fed onto polyurethane screen for dewatering, waste sand water through steel chute or rubber pipe in water tank and extracted by slurry pump into high pressure sediment separator, fine sand 0.16-3mm is sprayed onto polyurethane screen also for de-watering, the waste water is back to return box and flowing out.

Features
1. Both dehydration and recovery functions, which solves the problem of high fineness modulus and low stone powder content of finished sand in artificial aggregate processing system.
2. Above 95% fines recovery rate brought the direct economic benefit to customers is more than 15%, which has both environmental protection and economic benefits.
3. Improve the quality and productivity of finished products, fully solve the problems of sand washing machine.
4. Secondary washing function make the products cleaner.
5. Fines recovery unit can also provide more flexible process configuration for customer to meet the different production requirements besides the existing fixed group form.
6. Multi-function, easy to operate, saving investment cost and floor space.
