Product Description
Sand screening machine is an efficient and economical sand and stone separation equipment.
Sand screening machine, also known as dryland sand screening boat or sand and stone separator, is widely used in rivers, reservoirs, coal fields and construction sites. It is used for the separation and screening of sand and stone 1. It is mainly composed of hull (or frame), rack, reducer, conveyor belt, sift (usually drum type), engine or motor and other components. The structure is simple and easy to operate.
The working principle of the sand screening machine is to imitate the process of manually using the bevel screen to sift the sand, but the design of the flat rolling sieve cylinder is adopted. This design ensures that the material flow can continuously roll and sieve multiple turns (usually more than five turns) between the spiral blades in the sieve cylinder, so that the sand material can roll and slide repeatedly, so as to achieve full dispersion and separation. This method effectively avoids the problems of mutual extrusion and submersion of large and small materials that may be caused by the inclined roller sieve, as well as the problems of large and small materials oscillation and mixing caused by the inclined vibrating screen.
The main features of the sand screening machine include:
1. The installation foundation is simple: only a flat ground is needed, and it is easier to clean and maintain after the ground is hardened.
Two. Highly integrated: Except for the finished material stacking belt machine, all systems are integrated into an overall frame, which not only ensures the integrity of the equipment, but also leaves moderate maintenance and patrol space, which is convenient for construction site storage or transfer and transportation.
3. High work reliability: The core screening system adopts a stirring principle similar to that of a mixer. The raw materials are subject to continuous spiral blade rolling, extrusion and mutual friction between materials in the mixing cylinder. The screening effect is natural and reliable.
4. Economicality of use: The storage hopper has a large capacity, which can reasonably arrange the loading time of the loader and the sand screening machine and reduce the labor intensity; the sieve mesh adopts a replaceable piece connection method, which is convenient to replace or replace the sieve mesh of different sizes after wear.
In addition, the sand screening machine also has the advantages of flexible operation, reliable quality, compact structure, small area, low cost, high efficiency, convenient mobility and maintenance. It is an ideal machine to save manpower and financial resources, improve project quality, accelerate project progress, and increase economic benefits.
When using the sand screening machine, you need to pay attention to the following points:
1. Installation and debugging: Make sure that the sand screening machine is installed flat, the power supply is wired correctly, the parts are firmly installed, and the trial operation is carried out to check whether the equipment is working normally.
Two. Operation and maintenance: When starting the sand screening machine, the conveyor belt should be started first, and then the drum sieve should be started; when stopping, the drum sieve should be stopped first, and the conveyor belt should be stopped after the material on the conveyor belt is completely conveyed. At the same time, the lubrication of the turning part should be checked regularly, bearing butter should be injected, the sticky sand on the sieve should be cleaned, and the motor should be kept dry.
3. Troubleshooting: In case of problems such as conveyor belt deviation, waste material, and abnormal start-up, it should be investigated and repaired in time to ensure the normal operation of the sand screening machine.
Generally speaking, the sand screening machine is an efficient, economical and practical sand and stone separation equipment, which is widely used in various occasions that require sand and stone separation and screening.
