Product Description
Sand screening machine is a kind of mechanical equipment used for sand and stone separation, which is widely used in many fields such as rivers, reservoirs, coal fields and construction sites. The following is a detailed description of the sand screening machine:
I. Basic composition and working principle
1. Basic composition: The sand screening machine is mainly composed of hull (or frame), rack, reducer, conveyor belt, sieve (or rolling sieve), engine or motor and other components.
Two. Working principle: The sand screening machine imitates the working principle of manually using the bevel sieve mesh to sift sand, and adopts a flat rolling sieve cylinder to ensure that the material flows continuously between the spiral blades in multiple circles in the sieve cylinder, so that the sand material repeatedly rolls and slides and is fully discrete and separated.
II. Main features
1. Highly integrated: Except for the finished material stacking belt machine, all systems of the sand screening machine are integrated into an overall framework, 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 transportation.
Two. Work reliability: The screening system of the sand screening machine adopts advanced stirring principle. The raw materials are subjected to the rolling, extrusion and mutual friction between the materials of continuous spiral blades in the sieve cylinder. The screening effect is natural and reliable.
3. High screening efficiency: The flat design of the rolling sieve cylinder ensures that the material flow is rolled and sieved multiple times between the spiral blades of the sieve cylinder, so that the sand is repeatedly rolled and fully dispersed and screened, which improves the screening efficiency and accuracy.
4. Economicality: The structure of the sand screening machine is simple, economical and easy to operate, which reduces the cost of equipment and the difficulty of use. At the same time, the storage hopper has a large capacity, which is convenient for the loader to reasonably arrange the loading time and reduce the labor intensity.
5. Flexibility and customizability: The sand screening machine can configure different specifications of sieve mesh according to customer needs to achieve multi-level screening and meet a variety of screening needs. In addition, the equipment can also be customized according to actual needs to improve the flexibility and adaptability of use.
III. Types and Parameters
Sand screening machines are divided into many types, such as drum sand screening machine, washing drum sand screening machine, vibrating sieve sand screening machine, etc. Take the 50-type drum sand screening machine as an example, its parameters are as follows:
Roller size: 1m×3.5m (customizable)
Motor power: active motor 11KW, vibration 1KW, rolling 4KW
Whole machine size: 9.2m×1.9m×3.4m
Screen size: 1mm (customizable)
Hopper size: 3.7m×1.6m
Required voltage: 380V (diesel model can be customized)
IV. Use and maintenance
1. Preparation before use: The sand screening machine should be installed on a flat and solid ground to ensure the balance and stability of the equipment. At the same time, check whether the power connector is firm and reliable, whether the insulation is good, whether the grounding is correct, and add enough gear oil and bearing butter for the gearbox.
Two. Operation process: When starting the sand screening machine, first start the conveyor belt, and then start the drum sieve after it is normal. Adjust the unloading valve to achieve the required screening effect. When stopping, the drum screen must be stopped first, and the conveyor belt must be stopped after the materials on the conveyor belt are completely transported.
3. Maintenance: Regularly check the lubrication of the rotational part of the sand screening machine, and do not dry grind. At the same time, check the elasticity of the triangle belt, and regularly pour the bearing butter and clean up the sticky sand on the sieve. In addition, the motor should be prohibited from getting wet in the rain to ensure the safe operation of the equipment.
