2. INTRODUCTION
Sand plant produces the crushed sand as an
alternative of river sand. We have the
special sand making machine like VSI
crusher, sand screening machine like
vibrating screen. These sand crushing and
screening equipment are for maximum
productivity
3. SAND MAKING MACHINE
Sand Making Machine is a crushing plant
It is used to produce artificial sand by
crushing large size of rock materials. It is
also known as artificial sand making
machine and plaster sand making
4. Working
The sand washing plant is composed of jaw crusher, sand making machine, sand
washing machine, and belt conveyor. Its technology is that the stone materials are
uniformly sent to jaw crusher by vibrating feeder for crushing. Then the primary crusher
material sent to sand crusher machine by belt conveyors for further crushing. The finely
crushed material is sent to the vibrating screen for screening. The material meets the
requirements of the finished product size is sent to the sand machine for cleaning After
cleaning. The finished product is exported by the conveyor belt. The materials that do
not meet the requirements of the finished product size are returned from the vibrating
screen to the sand machine for re-processing, forming a closed circuit for many times.
5. In the production of machine-made sand, the sand washed by the sand washing
is cleaner and of better quality. The machine has gradually become an
important equipment of the artificial sand production line. The following issues
require our attention.
6.
7. Advantage
Simple Structure
Portable plant is available
Easy Installation
Working noise less than 7 5 decibels
Low operation and maintenance
High efficiency and high cutting efficiency
8. Disadvantage
Manufactured sand can be of a coarser and angular texture
than natural sand,
It is very smooth
This can lead to more water and cement requirement to
achieve the expected workability, leading to increased costs.
9. Application of sand
Construction
Railway
HydroPower station
Bridge and tunnel building
10. Installation Requirements
1. After the equipment arrived, the user unit should check whether the
parts are complete and no damage immediately. Make sure it is intact
before you install it.
2. The unit shall design the basic construction drawing of the sand
washing machine according to the specific situation on the spot. And
install the sand washing machine firmly on the solid concrete
foundation.
3. The spiral sand washing installation must be in accordance with the
requirements of the installation diagram to ensure the tilt angle.
4. The motor is installed on the guide rail to adjust the tightness of the
belt. The belt pulley and the motor pulley should be parallel during the
installation.
5. According to the above requirements, the rotor disk rotation several
11. Maintenance
Bearing is the most easily damaged part. Regular oil maintenance can increase service life.
2. Generally, every two months to check the work, wear and tear should be replaced
immediately. When using the sand washing machine with rolling bearing, the bearing
housings at both ends of the spiral shaft should be checked frequently. The reliability of
the bearing sealing device should be noted. If you find it wears, water seepage, sand
immersion, and other phenomena, the machine should be stopped immediately. Replace
seals and clean and lubricate bearings. In general, rolling Bearings oils every 5000 hours.
3. In daily use, we should always pay attention to whether the machine has noise. And
observes the screw shaft, triangle belt, sealing device, water pipe, and other parts. Check
whether the motor and gearbox are overheated. Whether the various parts of the bolt
fastening.
4. Gearbox in the operation of 3-6 months to clean and change the oil. Bearing every 6-12
months to replace the new grease.
5. Sand washing equipment seasonal maintenance is also very important. Mainly
replacement of oil, fuel, antifreeze, and increase refrigeration facilities.
6. When it working, it forbade someone to stand beside it and touch the machine body to
adjust, clean, overhaul and other operations.
