2. The discharge particle size is small and the particle shape is uniform.

3. The working noise is less than 75 decibels (dB level), and the dust pollution is less.

4. High crushing efficiency, with fine crushing and coarse grinding functions.

Principle: The material enters the sand making machine by the feed hopper, and the material is divided into two parts by the distributor, one part enters the high-speed rotating impeller by the middle of the distributor, and is rapidly accelerated in the impeller, and its acceleration can reach hundreds of times the gravitational acceleration, and then at a speed of 60-70 meters and seconds, it is projected out from the three evenly distributed runners of the impeller, and at first a part of the material that falls from the self-collection around the distributor is impacted and broken, and then impacts to the material lining layer in the vortex chamber together, and is hit by the material lining layer **, and the top of the vortex chamber is impacted obliquely upward, and change its direction of motion, deflect to downward motion, and the material emitted from the impeller channel forms a continuous material curtain. Such a piece of material is subjected to two or more chance of impact, friction and grinding in the vortex crushing chamber.

The crushed material is discharged from the lower discharge port.

Manufactured sand mainly has the following technical quality indicators in practical application:

For strength grade C60 concrete, the mixed sand fineness modulus shall not be lower, of which the extra-fine sand fineness modulus shall not be less than:

Strength grade C45-C55 concrete, mixed sand fineness modulus is not lower than, of which the fineness modulus of extra-fine sand is not less than.

When using mixed sand to prepare concrete with a strength grade of C60 or above, it should be tested to obtain reliable data, and it can only be used after being demonstrated to meet the performance requirements.

Machine-made sand refers to the sand processed by the sand making machine and other ancillary equipment (such as crusher, vibrating screen, feeder, sand washing machine and other sand and gravel production line equipment), the finished product is more regular, and can be processed into sand of different rules and sizes according to different process requirements, which can better meet daily needs. Machine-made sand requires professional equipment to produce qualified and suitable sand and gravel.

Common sand and gravel materials include river pebbles, pebbles, granite, basalt, quartz stone, limestone, dolomite, etc., which can be processed into high-quality machine-made sand through various sand making processes and sand production line equipment.

Machine-made sand: rock particles with a particle size smaller than those made by mechanical crushing and screening, but excluding soft rock, weathered rock particles;

Extra-fine sand: natural river sand with fineness modulus obtained according to the method specified in "Construction Sand" (GB T 14684);

Mixed sand: sand mixed with machine-made sand and extra-fine sand;

Machine-made sand concrete: concrete prepared with machine-made sand as fine aggregate;

Mixed sand concrete: concrete prepared with mixed sand as fine aggregate;

Plastic concrete: concrete with concrete mixture slump of 10-90mm;

High-fluidity concrete: concrete with concrete mixture slump equal to or greater than 160mm;

Pumped concrete: The slump of the concrete mixture is not less than 100mm and the concrete is pumped for construction.

Machine-made sand mainly has the following technical quality indicators in practical application: the strength grade C60 concrete is pure quiet fiber, and the mixed sand fineness modulus shall not be lower, of which the fineness of the extra-fine sand is not less than: the strength grade C45-C55 concrete, the imitation fineness modulus of the mixed sand is not less than, of which the fineness modulus of the extra-fine sand is not lower than that of the mixed sand when the strength grade concrete above C60 is prepared with mixed sand, it should pass the test to obtain reliable data, and it can only be used after demonstrating that it meets the performance requirements.

Compressive strength grade C60 cement concrete, mixed sand particle gradation can not be lower, of which the ultra-fine sand particle gradation is not less than: compressive strength level C45-C55 cement cherry section concrete, mixed sand particle gradation is not less than, of which the ultra-fine sand particle gradation is not less than the mixed sand configuration C60 above the compressive strength level cement concrete, should be tested to obtain stable data, after the sliding balance comparison ridge to meet the performance requirements can be used.

In order to avoid meeting growing economic growth, large equipment utilization seems to have doubled. Under the premise of active environment and satisfactory environmental protection, more useful and capable crusher equipment has become an important preference of customers.

Judging from the external layout of the new mediation, the operation of the new sand making machine is safer and more stable, and the production obedience and environmental protection level have been improved to a new level. The new sand making machine adopts the methods of "stone to stone" and "stone to iron", and promotes mediation according to the actual environment of the crushed material, which greatly improves the production capacity.

The raw materials of the wearing parts of the new sand making machine are made of high-quality wear-resistant materials at home and abroad, and the service life is long. A small number of wear-resistant parts are made of super-hard wear-resistant materials, which are small in size, light in weight, and easy to replace accessories.

The materials in the impeller and vortex crushing chamber of the new sand making machine can greatly reduce the cost and maintenance workload of wear parts, and the stone can form a protective bottom layer in the sand making process of the sand making machine, and the body is wear-resistant and durable.
