What Maintenance Work Should Be Done For Polyurethane Wear‑Resistant Components In Mineral Process

A large number of polyurethane wear‑resistant components serve inside mineral processing plant, including conveyor skirting, polyurethane scraper, vibrating screen panel and dewatering screen parts. These consumable components work under heavy impact, friction, moisture and dust environment. Simple standardized regular maintenance can effectively extend component service life and reduce unplanned production halt caused by sudden part failure.

Regular Inspection Of Polyurethane Skirting And Urethane Skirtboard Sealing

Check contact edge wear condition of polyurethane skirting at each transfer chute station. Observe whether tearing, local cutting crack or permanent deformation appears. For dual seal skirting, check sealing status of both inner and outer layers. Adjust mounting position properly after bottom edge wears. Fasten loose mounting bolt on time. Prevent bolt loosening causing skirting offset and large‑range material leakage accident.

Periodic Check For Conveyor Belt Cleaner And Polyurethane Scraper

Inspect scraper blade wear degree of conveyor belt cleaner. Observe whether blade edge produces notch, crack or partial peeling. Adjust spring buffer pre‑tightening force according to actual wear condition. Too‑large pre‑tightening force speeds scraper consumption and scratches belt surface. Check bracket anti‑rust condition for outdoor cleaner assembly. Replace failed polyurethane scraper before blade wears to metal base support.

Visual Inspection For Polyurethane Screen And Vibrating Screen Panel

During equipment shutdown period, carry out visual inspection for polyurethane screen panel. Check screen hole blocking condition, panel surface crack, edge tearing and fixing‑clamp fastening state. Clean accumulated sticky mineral residue on screen surface regularly. Timely replace partially damaged vibrating screen panel. Do not keep running with cracked screen plate, avoiding oversized‑particle leakage disturbing whole mineral grading effect.

Avoid Harmful Medium And Improper Operating Condition

Prevent strong solvent, special corrosive agent from long‑time direct contact with polyurethane wear‑resistant parts. Avoid local over‑high temperature acting on polyurethane surface. For production‑abnormal condition such as large lump ore direct impact, restore normal feeding state timely. Long‑term abnormal working condition accelerates material aging and mechanical damage for all kinds of polyurethane spare‑parts.

Record Wear Condition And Establish Spare‑Part Preparation Plan

Make simple running record for key polyurethane wear‑resistant components. Record installation time, average service cycle and damage mode. Summarize wear‑rule for different working stations. According to historical consumption data, make reasonable spare‑part stocking plan. It avoids emergency shortage of critical component and long‑time production halt. Historical wear record also provides reference for later material‑grade optimization procurement.
