product descriptionThe operation of the producing line is highly
emphasized since the sandstone aggregate is the base of the
architect materials. Base on the medium and long term development
plans for national infrastructure, sandstone consumption is
expected to increase by more than 10% every year, and the sand made
from cobblestone accounts for 60%. The mining of sandstone is
gradually developing towards the scale, yield, and environment
protection, and in addition, the government limits natural
sandstone mining in recent years, the exploitation of machine-made
sand is more and more important. Sand Making Plant is used to crush
rocks in the industries such as road construction, building
construction, construction materials, water and electricity and
civil building etc working with commercial concrete, dry mixed
mortar and mixing plant. It has functions such as feeding material,
making sand, screening, selecting powder, collecting dust,
elevating, storing material, measuring, ingredient, conveying and
controlling etc., It can produce the better sand with the features
of round article, continuous grading, the powder content can be
controlled and the modulus of fineness is stable. Working
principleAfter the ore raw material is coarsely crushed, it is fed
into a jaw crusher for primary crushing and screening, and then
through the conveyor sequentially enters medium crushing and fine
crushing cone crushers. At the meantime, the material of 5-30mm is
separated by the screening system and stored in the buffer bin at
the top of the sand making machine, and then is sent into four
vertical shaft crushers via the feeder. Afterwards it is conveyed
by a belt conveyor to the finished screening shop. The material of
>20mm is returned to the sand making machine through the belt
conveyor for crushing; the material of 10~20mm is stored as the
finished product in the finished product shed; the material of
0~5mm enters the washing system through the chute. System
introductionCrushing systemIn the whole production line, the
crushing system is divided into three parts: primary crushing,
medium & fine crushing and sand-making crushing. Primary crushing:
140mm < material fineness≤800mm Medium & fine crushing: 30mm
sand-making crushing: 5~30mm Screening systemAfter the crushing of
each part, the material will enter the corresponding material
fineness screening system, and is distributed to the corresponding
crushing system according to the fineness. Washing systemThe
material of 0-5mm separated by the screening systems is firstly
cleaned by their respective sand washing systems, then dewatered by
the dewatering screen, and finally stored in the finished product
shed. Wastewater utilization systemAfter the sludge-containing
wastewater is dewatered by the cyclone and the dewatering screen,
the slurry flows into the lifting tank and is transported by the
lift pump to the horizontal sedimentation tank. The bottom flow is
sent to the sludge tank through the plunger pump, and the upper
clear liquid flows into the clear water tank for production use.
The slurry in sludge tank is sent to the filter press by the filter
press feed pump. After the pressure filtration, the mud cake is
transported by the belt conveyor to the yard of the plant, and the
filtered water is discharged into the clear water tank for
recycling. Storage systemFully enclosed finished product shed
without dust leakage can meet the storage requirements of natural
sandstone, machine-made sand and finished aggregate.
One-card-controlled loading systemIntelligently controlling the
entire process of vehicle from weighing to loading and delivery can
simplify the process and integrate the corresponding information
system and automatic system, so as to reduce manual operations and
comprehensively improve delivery efficiency and customer
satisfaction. Host equipmentJaw crusherTraditional jaw crusher is
