Martin Marietta closes the $13.5 billion Lhoist deal
A Martin Marietta sand and gravel operation, from the company's newsroom.
On Monday Martin Marietta announced it had completed its combination with Lhoist North America the previous Friday, a $13.5 billion transaction. Lhoist North America makes high calcium lime, dolomitic lime and industrial minerals for domestic steel, infrastructure, heavy nonresidential construction and environmental markets. Chair and chief executive Ward Nye said the combination gives the company more than 2 billion tons of high quality reserves and makes it the nation's leading producer of limestone products. Martin Marietta already runs operations across 29 states, Canada and the Bahamas, so this reshapes who supplies a large share of North American stone.

Metso buys a pump line, and the spare parts business with it
From Metso's announcement of the acquisition.
On Monday Metso signed an agreement to acquire peristaltic hose pump and progressive cavity pump technologies from Valmet, along with the aftermarket spare parts and service capability that goes with them. The hose pumps are built for abrasive, corrosive, viscous and crystallizing slurries, with typical duties including thickener underflow, filter feed, flocculant dosing and slurry sampling. Tiago Marques Oliveira, who runs Metso's pumps business line, framed it around lifecycle support rather than the machines themselves. The deal closes October 1 and the value was not disclosed. Worth noting which way the wind blows: the aftermarket was the point.

Every piece from last week is still on the shelf, one to six of each, and nothing gets restocked at these prices. Ten more in the collection, from a $165 burn ring to a Telsmith 48 eccentric.
A 1953 mill replaced, and the silt pond turned into a product
Gavin Muzzle, superintendent supervisor at Custar Stone in Custar, Ohio.
On Friday McLanahan posted two minutes with Custar Stone in Ohio, a Gerken Materials limestone operation that ran its old mill from 1953 until a new plant started up late last year. Superintendent supervisor Gavin Muzzle walks the circuit: a triple deck wet screen making 57s, eights and nines, then a 44 double fines material washer running 121 tons an hour, with an ultra fines recovery system behind it. The part worth hearing is what happened to the waste. Fines that used to be dug out of the silt pond now test out as ag lime they can sell to farmers, so a disposal cost became a product.
What debris actually does to your crusher
Clearing the axle area, one of the spots that collects the most.
This week Eagle Crusher's service manager John worked through the housekeeping most often skipped on a crushing plant, and the mechanisms are worth knowing. Dust and rock debris packed around bearings holds heat in, which breaks down the lubrication and warps the metal. Clutch openings collect the same debris and wear for no reason. On the fuel tank, built up material can cut or shift the lines running into it. Walkways and axle areas are about the crew rather than the machine, but a cluttered walkway is how people get hurt. None of it is complicated. It is the kind of thing that quietly decides whether a bearing reaches its rated life.
The first letter of gearbox maintenance
Erik Teriele of Dodge Industrial on the L in L.U.B.E., 58 seconds.
On Wednesday Dodge Industrial started a short series on maintaining the Tigear-2 worm gearbox, built around the acronym L.U.B.E. Global product manager Erik Teriele takes the L first, and it stands for lubed for life. Every Tigear-2 is filled and sealed at the factory in Belton, South Carolina with a food grade oil chosen in their own wear testing, and it is meant to last the life of the box. In other words the correct maintenance for that item is none. Under a minute, one clear answer, and the U follows next.
