4 Types Of Sand Making Machine

1. Compound crusher

Processing capacity: 5-100t/h

Production advantage: Good sand making effect on wet materials.

The compound crusher adopts a hammerhead for graded crushing. It is suitable for medium-hardness stone sand-making processes like limestone. It can directly crush materials to a particle size 3-5mm.

• The crushing and sand-making effect is also better for stones containing a small amount of moisture, and the design of no sieve bottom discharge can smoothly achieve the smooth discharge of wet materials. The structural design adopts a single-sided door opening setting, conducive to equipment inspection and maintenance operations during long-term production.
• This series of crushers is suitable for crushing limestone, clinker, coal, and other ores in the building materials, mining, metallurgy, and chemical industries. Its compressive strength shall not exceed 140 megapascals, and its humidity shall not exceed 15%.

Working principle

After the material enters the machine body from the feeding port, it falls onto the surface of the rotor. Due to the high-speed rotation of the rotor with the main shaft, the material is synchronized with the high-speed rotation of the main shaft through the protruding scattering plate on the rotor and is thrown onto the counterattack plate. Due to the unique structure of the counterattack plate, the material will bounce back, downward and inward gathering motion, entering the crushing chamber, and being hit by the counterattack plate. After the impact of the counterattack plate, it moves in a “Z” shape around the rotor until it is crushed to a certain particle size and discharged from the discharge port.

2. Heavy hammer crusher

Processing capacity: 60-3000t/h

Production advantage: crushing and sand making for one-time molding

The heavy hammer crusher uses a hammerhead to strike and crush stone materials. It is suitable for crushing hard stones to sand. This machine has the advantages of reducing the wear of the hammerhead and lowering the maintenance cost.

The heavy hammer sand-making machine production capacity reaches 3000 tons per hour, which is very suitable for the production needs of large-scale sand and gravel fields. It achieves one-time crushing and molding without secondary operations, and a single machine is a complete production line.

Working principle

The electric motor drives the rotor to rotate at a high speed inside the crushing chamber. The material is fed into the machine from the upper feeding port and crushed by the impact, shearing, and grinding of a high-speed moving hammer. At the lower part of the rotor, there is a sieve plate. The particles smaller than the sieve hole size in the crushed material are discharged through the sieve plate, while the coarse particles larger than the sieve hole size are retained on the sieve plate and continue to be hit and ground by the hammer before being discharged through the sieve plate machine.

3. Vertical shaft impact sand making machine

Processing capacity: 40-650t/h

Production advantages: advantages in sand making and stone shaping from stone materials

The VSI sand-making machine can meet the sand-making and crushing operations of various hard stones, and use the friction formed by the collision between stone materials to crush them. The crushed stone products are adjustable between 1-5mm.

• The equipment adopts a dual motor configuration for high efficiency and is equipped with a pulse dust removal device to reduce industrial dust. It also has a door-opening device for timely shutdown, inspection, and maintenance.
• VSI sand-making machine is a new generation of impact sand-making machine. It is currently one of the most advanced high-performance sand-making equipment. Compared with other sand-making machines, this machine has higher output, better particle shape, and lower operating cost. It provides high-quality sand and gravel aggregates for highways, high-speed railways, high-rise buildings, municipal engineering, hydropower dam construction, and concrete mixing plants. VSI sand-making machine is a good choice for manual sand-making and stone shaping.

Working principle

The VSI vertical axis impact crusher is a device that crushes materials based on the principles of high-speed motion, mutual impact, and friction. Its working principle is to achieve the crushing and shaping of hard materials through the motion and contact force of the material itself.

       4. Fine sand making machine

Processing capacity: 5-260t/h

Production advantage: less affected by material moisture content

The fine sand crusher is a crushing equipment with fine particle size output. Because the discharge is comparable to sand, it is also a fine sand-making machine. The equipment is less affected by the moisture content of the material, and the moisture content can reach around 8%.

• Fine crusher is high-efficiency fine crusher, third-generation fine crusher, etc. This machine has a wide range of applications, and its performance has reached the international leading level. It is currently the most effective, practical, and reliable crushing machine, especially suitable for the production of abrasives, refractory materials, cement, quartz sand, steel sand, slag powder, copper ore, iron ore, gold ore, concrete bone materials, asphalt aggregates, and other hard and brittle materials.
• It is an efficient and energy-saving crushing equipment for sand production, saving 50% of energy compared to traditional crushing machines.
• The discharge port has a graceless adjustment device, which can conveniently and quickly control the particle size of the discharge. It is good equipment for discharging moisture-containing stones, discharging smoothly without blockage.

Working principle

The fine crusher is a continuous operation equipment. During operation, the rotor rotates at high speed under the motor. The material enters the first crushing chamber for crushing, collides with the plate hammer on the rotor, and then enters the second crushing chamber for crushing. Finally, discharge the material.
