Calcium carbonate powder has uniform fineness and good fluidity, but it is prone to agglomeration or contamination with impurities during storage and transportation, which directly affects product quality. Efficient screening is a key step to ensure its purity before packaging.  

Straight discharge screen: The core equipment for efficient screening

The straight discharge screen is driven by a vertical vibration motor, generating three-dimensional vibration, which enables the material to quickly disperse and spiral on the screen surface. Qualified powder passes through the mesh rapidly, while impurities are automatically discharged from the impurity outlet. Its straight discharge design ensures a short material retention time and high processing capacity, making it particularly suitable for continuous screening of calcium carbonate powder.  

The prominent features of the straight-through vibrating screen are as follows:

1. High efficiency and clog prevention: The unique vibration trajectory combined with the angle of the screen mesh significantly reduces the problem of calcium carbonate powder clogging the screen.

2. Precise classification: The multi-layer screen mesh configuration enables multi-level screening and precise control of powder particle size.

3. Sealed and environmentally friendly: The fully enclosed structure ensures dust-free screening, and the flange interface facilitates connection to the production line.

4. Easy maintenance: The screen mesh can be quickly disassembled and assembled, and the stainless steel structure is corrosion-resistant, suitable for long-term continuous operation. 

From equipment to complete production lines: A case study of a Chilean production line

We not only offer high-performance straight-through screens, but also have the capability to design and integrate entire production lines. For instance, the calcium carbonate powder packaging line we created for a Chilean client includes the following components:

Dust-free feeding station → Straight-through screen → Vacuum feeder → Screw belt mixer → Secondary vacuum feeder → 25kg powder packaging machine → Sealing and sewing machine

This production line takes the straight screen as the core screening unit, achieving full-process automation from material feeding to packaging, demonstrating our comprehensive strength in providing one-stop solutions.
