The presence in the VSI crushing market has expanded significantly since the acquisition of the former CEMCO in late 2023. With market share tripling over the past year, now is an ideal time to emphasize the necessity of regular inspections and proactive maintenance.
Unlike compression-style crushers, a VSI crusher relies on continuous, high-speed impact to fracture material. This results in faster wear, making regular maintenance essential for safe and efficient operation. Even a single neglected component can throw the machine out of balance, leading to significant operational issues.
Service technicians frequently encounter the consequences of inadequate VSI maintenance. Without regular inspections, worn components can create imbalance, causing excessive vibration and structural damage. In some cases, material can wear through anvils and begin cutting into the crusher body itself—turning a minor issue into a major repair.
Well-organized operators typically inspect their VSI crushers at the beginning or end of each shift, helping to identify wear and misalignment before they escalate into larger problems. In high-abrasion applications, such as manufactured sand production or quartzite crushing, inspections may be necessary as often as every four hours.
A well-maintained VSI crusher ensures consistent product quality, reduced downtime, and extended component life. Below are the critical areas to inspect to prevent performance issues and costly repairs.
The rotor is the core of a VSI crusher, spinning at high speeds to propel rock into wear surfaces. An unbalanced or worn rotor can cause excessive vibration, reduced efficiency, and structural damage.
The high-speed operation of VSI crushers places significant stress on the bearings, making proper lubrication essential to preventing premature wear, overheating, and failure.
The crushing chamber is where rock fractures upon impact. VSI crushers use either anvil rings (rock-on-steel) or rock shelves (rock-on-rock) for material reduction.
The feed system controls material entry into the rotor. Blockages, misalignment, or excessive wear can disrupt crushing performance.
Regular VSI inspections require time, but neglecting them leads to far greater costs. Even a single worn part left unchecked can escalate into significant downtime and expensive repairs. A few minutes of inspection can prevent days of lost production and thousands in repair costs.
Proactive maintenance not only extends VSI crusher life but also keeps production on track, preventing shutdowns that can impact profitability.
