Mobile sand screening machine

Sand screening machine is a kind of equipment used for sand and stone separation, which is widely used in rivers, reservoirs, coal yards, construction sites and other scenes.

1. Basic structure and working principle:

The sand screening machine, also known as the dryland sand screening ship and the sand and stone separator, is mainly composed of hull (or frame), shelf, reducer, conveyor belt, sift (drum screen or vibrating screen), engine or motor and other components.

Its working principle is to imitate the manual use of the bevel screen to sieve the sand, and use a flat rolling sieve cylinder or a vibrating sieve to make the sand repeatedly roll and slide on the sieve or sieve, so as to fully disperse and separate the coarse and fine materials.

Two. Main types:

Roller sand screening machine: drive the sand to roll in the cylinder through the rotation of the drum to achieve screening.

Washing drum sand screening machine: On the basis of drum screening, the washing function is added, which is used to clean the sand.

Vibrating sieve sand screening machine: Through the up and down vibration of the vibrating sieve, the sand can jump and roll on the sieve to achieve screening.

3. Features and advantages:

The installation foundation is simple: only need to level the ground, and the hardening of the ground is more convenient for cleaning.

Highly integrated: All systems are integrated into an overall framework, which is convenient for storage, transfer, transportation and maintenance.

High work reliability: The screening system adopts the principle of stirring, and the raw materials are rolled and pushed by continuous spiral blades in the sieve cylinder, and the screening is thorough.

Economy of use: the storage hopper has a large capacity, which reduces labor intensity; the sieve mesh can be replaced, which is convenient to replace or replace the sieve mesh of different sizes after wear.

High screening efficiency: the sieve hole is not easy to block, the operation is smooth, and the noise is small; the whole machine is highly reliable and the one-time investment is less.

4. Use and maintenance:

Before use, it is necessary to ensure that the sand screening machine is placed smoothly, and check whether the power supply, transmission parts, etc. are normal.

When starting, start the conveyor belt first, then start the drum screen or vibrating screen, and adjust the unloading valve to the appropriate position.

When stopping, you need to stop the drum screen or vibrating screen first, and then stop the conveyor belt after the materials on the conveyor belt are completely transported.

Regularly check the lubrication of the rotation part, inject bearing butter, clean up the sticky sand on the sieve, and ensure the normal operation of the equipment.

5. Field of application:

Sand screening machine is widely used in mixing stations, road and bridge projects, construction sites, sand quarry, coal yards, grain stations and other fields. It is an ideal machine to save manpower and financial resources, improve project quality, accelerate project progress and increase economic benefits.
