Cement

Put Precision solutions to work in your cement manufacturing operations to resolve problems and gain efficiencies.

Maintain machines during your planned outages, NOT when the machine fails!   Feeders and valves that fail unexpectedly and cause unplanned downtime cost you production and profitability. With Precision Predictable Performance, feeders and valves last for their rated life. Address routine maintenance and rebuilding on your schedule.

Precision’s Done Right, On-Time Guarantee = faster deliveries, fewer spares.  When it’s time to rebuild or replace, Precision gets you the right solution, on YOUR schedule. No need to wait 10+ weeks for an overseas solution. We’re nearby and ready to go to work for you. No need to carry excess spares. Let us help shorten your outage.

Make tight maintenance budgets go further.  Stop spending the same money on the same problems every year. Let Precision customize a solution to your material feeding headaches – and stay under budget!

Lower your Total Costs:  Energy, Repairs and More.  There’s constant pressure on cost-per-ton. Every penny saved per pound adds up. Precision’s innovative and high-performance solutions are engineered with “total cost of ownership” in mind.

Keep materials moving – even the ones that build-up, stick and disrupt typical machinery.  Precision equipment will keep them moving, consistently, easily and without constant operator intervention. No more need to worry about material flow or assigning employees to fix clogs and spills.
