How to Install Mining Chute Liners with Counter-Bored Bolting

Overview

This guide covers the practical steps to install mining chute liners with counter-bored bolting. JSLT Mining produces engineering plastic components in UHMWPE, HDPE, PA, POM and PTFE — full-process fabrication from raw sheet to CNC-machined parts.

Step-by-step procedure

1. Survey chute geometry. Map chute walls; record corners, transitions, and bolt access.
2. Lay out liner panels. Plan panels to maximize size while allowing access for bolting.
3. Drill counter-bores. Counter-bore liners 1.5× bolt-head diameter for thermal expansion.
4. Bolt with washers. Mechanical fastening using stainless M12–M16 with large flat washers.
5. Inspect first wear cycle. Tighten any loose bolts after 100 operating hours.
