Construction waste is the reusable resources, but it doesn’t have a better using before and causes great amount of pollution for underwater. Human becomes aware of this problem and many policies are published for environmental protection, then many mining production investors seek a new way for green production line building.

1. Construction Waste introduction

Construction waste refers to the materials produced in construction, such as the materials of waste soil, muck, sludge, and waste materials.

2. Problems in handling construction waste

a. Large amount of construction waste and increasingly market scale.

b. Lower recycling rates, and huge environment pollution.

c. Single handling way and small production scale.

d. Incomplete laws and regulation and unsound management system.

e. Low technology level and poor selection.

f. Lack of regulation.

3. Construction waste sand maker

a. Sand maker working principle

Materials fall into sand maker chamber from the top of machines and then they are crushed by around liner with centrifugal force and then materials will be crushed by hammer and shell. And qualified materials will be discharged from the under of machine and unqualified materials will be crushed again for demanded finished materials.

b. Construction waste sand maker performance feature

Construction waste sand maker is mainly used for crushing medium hardness materials in mining, refractory, cement, coal, glass, and electricity industry.

i. Huge crushing ratio, higher production capacity, and stable operation.

ii. Regular machine lubrication, longer machine service life and working efficiency.

iii. Large shaping capacity, fine material shape, and cubic and quality material.

iv. Automation machine opening and closing device, short machine maintenance time, easy machine spare parts changing.

4. Construction waste sand making production line working process

Stone materials will firstly be crushed by crusher machine for coarse crushing and then coarse materials will be fine crushed by other crusher machine after conveyed into machines by belt conveyor. Fine crushed materials will screen two kinds of materials with vibrating screen and then they will have sand making process by sand maker. Sand materials will be washed by sand washing mateirals by sand washer for qualified materials in construction building.

5. Construction waste recycling application

Construction waste will be used for screening and crushing for cement and concrete material making, construction aggregates, chemical material, and metallurgy production. Meanwhile, produced materials will be used for making bricks and steel and other metal materials will be reusing after melting.
