The product enables online installation, which means that the cement silo does not need to be shut down in order to complete the installation. Once installed, it can clear the discharge port, ensuring that the cement silo no longer experiences blockages with a success rate of up to 95%. The product has a simple structure, easy operation, and low cost. On-site installation services are available. The appearance of the product is similar to that of the existing air cannons on the market, but it includes a secondary pulse generator and a specialized blockage clearing pipe to guarantee the clearing effect.
