Dry sand method: no water is needed.

Wet sand production method: a lot of precious water resources need to be consumed in the production process.

2. Different environmental impacts:

Dry sand method: this technology is recognized as a good technology and has little impact on the environment.

How to make wet sand:? Have a great impact on the environment.

3. Quality of finished sand

Dry sand method: the cost is higher.

How to make wet sand:? Although both water and classifier can remove mud powder from sand, the effect of wet sand production will be better. This kind of finished sand used in construction industry can greatly increase its compressive strength and machinability.

Extended data:

A, sander matters needing attention:

1. Before driving, check whether the observation door of the vortex cavity is closed, so as to prevent the materials from rushing out of the observation door of the vortex cavity, causing danger.

4. Observe from the inlet direction and check the rotating direction of the impeller. The impeller should rotate counterclockwise, otherwise the motor wiring should be adjusted.

3. The starting sequence of crusher and conveying equipment is: discharging → crusher → feeding.

4. The crusher must be started with no load, and the feeding direction is after the normal operation of the crusher, and the stop sequence is opposite to the start sequence.

5. When the discharging equipment stops, stop feeding in time, otherwise it will crush the impeller and burn out the motor.

[6], feeding should be continuous and uniform.

7, crusher operation process, can not have severe vibration and abnormal noise, otherwise, should stop the machine for inspection.

Second, the use of sand making machine:

1, river pebbles and rocks (limestone, granite, basalt, diabase, andesite, etc.) produced by artificial sand. ), ore tailings and stone chips.

2. Production of building aggregates, road fabrics, cushion materials, asphalt concrete and cement concrete aggregates.

3. Machine-made sand production and stone molding in water conservancy and hydropower, high-grade highways, expressway, high-speed railways, passenger dedicated lines, bridges, airport runways, municipal works and high-rise buildings.

4. Pre-grinding and fine crushing process in mining field, crushing materials in building materials, metallurgy, chemicals, mines, refractories, cement, abrasives and other industries.
