River Pebble Sand Making Machine

    product description

    River pebble sand making machine has the following characteristics: small size of sand and gravel output, uniform grain shape, large production capacity, long hammer life, small supporting power, change from third-level crushing to second-level crushing, simplified process, simple structure, and convenient maintenance ,Running smoothly. River pebble sand making equipment investment is 35% -50% lower than traditional technology equipment of the same scale, and the output efficiency is higher than 35% -50% of traditional technology equipment of the same scale. Taking limestone as an example: the size of a finished product ≤ 5mm accounts for 85% . The operation and maintenance cost is lower than 35% -50% of the traditional technology equipment of the same scale, and it is widely used in the industries such as sand, cement, refractory, metallurgy, and chemical industry.


    River pebble has higher hardness but higher silicon content. Therefore, the crushing process of river pebble should be designed reasonably. While considering the investment cost of river pebble sand making machine, the production cost of the production line must be considered. In the crushing operation of the raw material is river pebble, the wear of jaw plate, plate hammer, impact plate and other wear parts is very high. Therefore, in the design of the river pebble sand making process, the crushing equipment of the lamination principle is used as much as possible to reduce the wear of the wear-resistant parts. Typical lamination equipment configuration is a two-stage jaw crusher or jaw crusher plus cone crusher process configuration. If the customer has high requirements for the stone particle size, an additional impact crusher can be configured to perform the crushing, so that a three-stage crushing process configuration is formed. Three-stage crushing will inevitably lead to higher investment costs for the project, but for long-term operation of the stone plant, the three-stage crushing will reduce the production cost significantly. For more difficult stone materials such as river pebbles, a two-stage crushing process of jaw crushing and reverse crushing can also be used. However, this will inevitably lead to problems such as high plate hammer loss, short plate hammer life, and high ratio of anti-reverse materials. These problems deserve attention from manufacturers and customers.

    Product advantages

    1. River pebble sand making machine has a high degree of automation. In addition to the startup and shutdown of the equipment and daily maintenance, the entire production line has a simple process and requires almost no manual operation.

    2. High production efficiency and low operating cost.

    3. The output is large, the yield is high, and the particle size of the finished stone is uniform.

    4. Small area, high investment economic benefit.


    Benefit analysis of river pebble sand making machine:

    1. The investment of river pebble sand making machine is only 1 / 3-1 / 5 of the conventional production line with the same processing capacity.

    2. The production cost of river pebble sand making machine is only 1 / 3-1 / 4 of the conventional production line.

    3. The investment recovery period is short.

    working principle

    The river pebble sand produced by the river pebble sand making machine has become the main sand making machine industry in construction production. It has a good development trend, and has become a traditional and brand new entrepreneurial field.

    River pebble sand production line is a combination of vibration feeder, jaw crusher, sand making machine, vibrating screen, sand washing machine and other equipment.

    Vibration feeder: uniformly feed materials into the crusher for the first crushing work.

    Jaw Crusher: complete the initial crushing of the material.

    Sand making machine: further crush the crushed material.

    Sand washing machine: finished sand after washing.
