PLS Series Vertical Shaft Impact Crusher is multi‑purpose tertiary fine‑crushing, sand‑making and aggregate‑shaping equipment. Dual rock‑on‑rock / rock‑on‑iron working modes produce high‑quality cubical manufactured sand for quarry, mining and construction‑waste recycling. Supports fixed‑plant and mobile‑crushing‑station integration.
PLS Series Vertical Shaft Impact Crusher
PLS Series Vertical Shaft Impact Crusher is high‑performance tertiary fine‑crushing, sand‑making and aggregate‑shaping equipment. It supports switchable rock‑on‑rock / rock‑on‑iron working modes, producing well‑rounded cubical manufactured sand and high‑grade aggregate. Widely deployed in fixed crushing lines and also integrable onto mobile crushing stations for onsite sand production.
Product Overview & Core Features
- Dual‑mode Switchable Crushing Principle
Two working modes: rock‑on‑rock for highly‑abrasive hard rock (low wear cost); rock‑on‑iron for high sand‑yield of medium‑hard materials. Quick part replacement to switch modes without modifying main machine structure. - Deep‑cavity Impeller Design
Deep‑cavity impeller delivers large throughput. Material self‑protection layer inside rotor greatly reduces direct wear on metal components, extending service life of wear‑resistant parts. - Excellent Particle Shape Output
Produces cubical‑shaped finished products with low flakiness index. Fineness modulus can be adjusted by changing impeller rotating speed, meeting strict requirements for highway, high‑speed‑rail and hydropower concrete aggregate. - Multiple Lubrication & Intelligent PLC Monitoring Options
Optional thin‑oil forced lubrication or dry‑oil grease lubrication for different site conditions. PLC system monitors spindle temperature, vibration, motor current, with early‑warning alarm for unattended continuous production. - Hydraulic Opening Structure for Easy Maintenance
Hydraulic top‑open cover design enables fast access to impeller and wear liners. Shorten wear‑part replacement downtime, raise overall plant operation rate.

FAQ
What is the difference between rock‑on‑rock and rock‑on‑iron mode?
Rock‑on‑rock: materials collide against each other, low metal wear, fit for extra‑hard, high‑abrasive rock. Rock‑on‑iron: materials hit metal impact liners, higher sand‑making ratio, better for medium‑hard rock such as limestone, dolomite.
What is the estimated pay‑back / return‑of‑investment cycle for a PLS sand‑making production line?
Pay‑back period heavily depends on local sand market price, raw‑material cost, electricity price and actual operating hours. For stable‑running commercial‑grade manufactured‑sand projects: typical pay‑back ranges 8‑18 months. If natural sand resource is scarce locally, pay‑back can shorten to 6‑10 months. Hard‑abrasive rock will increase wear‑part running cost and slightly extend return‑of‑investment cycle. Our engineers can provide customized economic calculation according to your site data.
Can PLS vertical shaft impact crusher be installed on tracked mobile crushing plant?
Yes. It can be integrated as mobile sand‑making unit. It is commonly matched with cone / jaw crusher and vibrating screen to form complete mobile aggregate & sand production solution.
What feed size should be fed into PLS crusher?
Strictly follow model‑specified max feed size. Oversized feed will cause heavy impeller wear, vibration and unexpected shutdown. Oversize material should be pre‑crushed by cone crusher before feeding into VSI.
Can PLS process wet raw materials?
Material moisture content better kept below 15‑20%. Too much sticky wet material may cause cavity blocking. If feed material contains high moisture, add pre‑drying or pre‑screening process.
How to adjust finished sand fineness modulus?
Adjust impeller rotating speed; also adjust feed rate and cooperate with vibrating screen classification to get target fineness modulus for different concrete grades.
What are the key routine‑maintenance items?
1) Check impeller, impact blocks and wear‑resistant liners regularly; 2) Monitor lubrication oil temperature, oil cleanliness; 3) Check PLC vibration & temperature alarm logs; 4) Replace damaged wear‑parts timely to avoid secondary equipment damage.
