How do you calculate dust protection cost for mining equipment?

Multiply the number of sealing points by the cost per point, then by the share of points actually being upgraded, and add the fixed pressurizer charge. With 24 points at $320, an 80% upgrade share and a $4,500 pressurizer, that is 24 x 320 x 0.80 + 4,500 = $10,644.

What is a typical cost per sealing point on a mining machine?

Gasket reseals and cable-gland upgrades run roughly $150-$400 per point, while full sealed enclosure or IP-rated cabinet conversions can exceed $1,000. The $320 default sits in the realistic mid-range for cab and electrical sealing work.

Why is the pressurization system a separate fixed cost?

A cab or cabinet pressurizer (blower, filter bank, pressure switch) is a one-time install whose cost does not scale with the number of sealing points, so it is added as a fixed $4,500 adder rather than spread across points.

What does the cost per unit figure mean here?

It is the total cost divided by sealing points, $10,644 / 24 = $443.50 per point, which is a useful blended benchmark when comparing one sealing scope against another.

How do I lower dust protection cost without losing reliability?

Lower the upgrade share by triaging only the points that fail dust audits, standardize on one gland and gasket spec to cut per-point cost, and reuse an existing pressurizer plenum where possible to shrink the fixed adder.

Is dust protection cost a capital or maintenance expense?

On a rebuild it is usually capitalized with the machine refurbishment, but standalone reseal campaigns on in-service equipment are typically booked as maintenance; the calculator gives the dollar figure either way.

Mining Vehicle & Underground Equipment calculator

Dust Protection Cost Calculator

Dust protection cost captures what it actually takes to keep abrasive coal, silica and ore fines out of cabs, electrical cabinets, bearings and HVAC on underground and surface mining equipment. Reliability engineers and rebuild-shop estimators use it to budget enclosure sealing, filter housings and cab pressurization before a machine goes back into a dusty heading. It matters because dust ingress is the single biggest driver of premature electronics and bearing failure on diesel and electric mining fleets, and a few hundred dollars per sealing point is far cheaper than an unplanned tramming-motor swap underground. This calculator separates the variable sealing spend from the fixed pressurizer charge so you can see both the total and the cost per sealing point.

What this calculator does

Estimate the cost of dust ingress protection on mining vehicles, including cab sealing, filtration, and positive-pressure systems for respirable silica control.
An equipment builder specifying dust protection for an underground loader operating in high respirable-dust conditions.
It computes the total dust protection cost as sealing points multiplied by cost per point and the upgrade share, plus a fixed pressurization system charge.

Formula used

Dust protection cost = sealing points x cost per point x upgrade share % + pressurizer
Cost per sealing point = total cost / sealing points

Inputs explained

Sealed enclosures and filters:
Cost per sealing point:
Points needing upgrade:
Pressurization system charge:

How to use the result

Use it when scoping a dust-ingress upgrade during a machine rebuild, mid-life refurbishment, or when quoting a sealing retrofit for a specific underground duty.
It assumes a single average cost per sealing point; a job mixing cheap gasket reseals with full IP66 cabinet swaps needs to be split into separate runs or you will under- or over-state the variable cost.
