Controlling build-ups in dry process cement production

MARTIN ENGINEERING

1 CAT 5, modern technology to prevent build-ups

2 Single tank cannons are often strategically timed with a coordinated firing sequence to prevent blockages

3 Hurricane air cannon at a riser duct

4 The multi-port air cannon system delivers its air blast to as many as eight ports using an air cylinder, without conventional valves

5 A typical air cannon discharge reaches its peak blast force output in the milliseconds just after the valve is opened, dropping quickly as the tank pressure approaches zero

6 An air cannon discharge with a return reservoir achieves the same peak force output, but air consumption is reduced by about half

Efficient cement production with less build-ups

The benefits of high-efficiency air cannon networks can include reduced energy costs, improved system performance, reduced maintenance, improved safety and greater total output.

Efficient material flow is a critical element of dry-process cement manufacturing, and accumulation or blockages can put a choke hold on a plant’s profitability. Hang-ups in storage systems and build-up in process vessels can impede material movement, causing bottlenecks that interfere with equipment performance and reduce process efficiency. Poor material flow also raises maintenance expenses, diverting manpower from core activities and in some cases introducing safety risks for personnel. If they become severe enough, flow problems can bring production to a complete stop. Although many...
