Stone sand making machine, also called stone sand making machine, also called double-roller sand making machine, double-roller crusher, double-roller machine, double-roller crusher, uses two motors to drive two pairs of rollers to squeeze and grind materials. When working, the crushed materials have better effects than ordinary crushing machinery. It can crush various stones with a compressive strength of less than 160 MPa. It has the characteristics of low maintenance cost, less water consumption, stable performance, low power consumption and dust Less noise and less noise. The demand for sand and gravel aggregates has increased significantly, which has led to the development of artificial sand making. The use of stone sand making machines for sand making processing can provide finished products of different sizes to meet market demand.
1. The stone sand making machine is better than the hammer sand making machine and does not need to replace wearing parts.
2. The sand has full grain shape, reasonable gradation, low over-grinding rate and high output.
3. The stone sand making machine has huge advantages over hammer crushers and impact crushers. The average service life of the roller sleeve is more than 2 years.
4. Huashengming high-chromium manganese steel wear-resistant material contains rare metal roller skin material, which is wear-resistant, durable and high-temperature resistant. The discharge granularity can be adjusted at will from 1-3mm.
1. The finished product has good grain shape and less over-powder.
2. The particle size of the finished product is simple and controllable
3. Reasonable structure, no clogging, no stickiness
4. Dual motors, full of power
5. The roller skin is made of highly wear-resistant manganese steel, which is more durable.
6. Low investment cost, economical and easy to use
The stone sand making machine uses two sets of independently driven rollers to crush materials by squeezing and grinding shear forces generated by relative rotation. The material falls between the two rollers through the feeding port. After being squeezed and crushed by the pair of rollers, the finished product falls naturally. When encountering extremely hard or unbreakable materials, the rollers can automatically retreat by the action of the hydraulic cylinder or spring, making the gap between the two rollers The gap between the two rollers increases, and the hard or unbreakable materials naturally fall down to ensure that the machine is not damaged. The two oppositely rotating rollers can adjust the pressure of the hydraulic cylinder or spring to control the discharging granularity of the product.
