* Firm cuts 1,100 jobs and lowers outlook
* Mining capital spending deteriorates
* Shares up 7 pct in heaviest trading volume since May (Adds CEO, analyst comment)

COPENHAGEN, Aug 23 (Reuters) - Danish engineering group FLSmidth said it will shed 1,100 jobs and lowered its financial forecasts as miners spend less on equipment.
FLSmidth reported a surprise 40 percent drop in second-quarter operating profit on Friday, as it booked 323 million Danish crowns ($57.8 million) in one-off costs at its division that sells gear for cutting, crushing and transporting metal ores.
The company, which operates mainly outside Denmark in locations including Africa, the United States and Australia, warned it will take 1.35 billion crowns of writedowns and one-off costs by the end of the year.
Miners led by BHP Billiton and Rio Tinto are slashing billions of dollars of capital expenditure in response to lower metals prices and shareholder pressure to boost returns, after a decade of expansion.
This hurts engineers that build and sell the gigantic ore-handling equipment, like FLSmidth and its Nordic peers, Metso, Sandvik and Atlas Copco.
"We expect mining capex will hit bottom in 2014," said FLSmidth Chief Executive Thomas Schulz, who took the reins on April 1, told a conference call with analysts.
FLSmidth said it will cut about 7 percent of its staff which, along with other efficiency measures, will result in 350 million crowns of costs to be booked by the end of the year. It will take another 150 million of efficiency costs after 2013.
The company said it will cut its 200 locations by about 10 percent.
The firm hopes the job cuts and other measures will boost earnings before interest, tax and amortisation (EBITA) by 750 million crowns annually from 2015. EBITA was 287 million crowns in financial second quarter, hit by 323 million crowns of one-off costs.
FLSmidth shares jumped nearly 7 percent on Friday, in the busiest trading since mid-May and the second-biggest volume in more than a year.
Before the job cuts announcement, the shares were down 11 percent in the year to date, making them the worst performers in the Danish OMXC20 index.
FLSmidth expects to write down inventories for 200 million crowns in the third quarter and book an impairment of about 800 million crowns on Australian minerals processing group Ludowici, which it acquired in 2012 for 388 million Australian dollars (2.46 billion crowns).
"Looking at the risks associated with these old projects, I took the decision to clean that out," Schulz said.
Analysts say it makes sense for new chief executives to book any charges or restructuring costs at the beginning of their mandate.
"It looks like a real spring cleaning to me," Sydbank analyst Jacob Pedersen said.
The company cut its full-year revenue outlook to 26-28 billion crowns from 27-30 billion crowns and halved its EBITA margin guidance to 4-5 percent.
"From the picture they paint of the state of the markets, particularly mining, it sounds like they have some difficult years coming," Sydbank's Pedersen said.
Earnings before interest and tax (EBIT) fell to 195 million Danish crowns in May-July against a forecast rise to 384 million crowns in a Reuters poll.
"We are positively surprised by the cost initiatives announced by the new CEO," Jyske Bank analyst Janne Kjaer said in a note to clients. "This should help bring margins back towards the 10-11 percent range."
Morgan Stanley said in a research note that capex spending for five major miners including BHP, Rio Tinto, Anglo American , Glencore and Vale is set to fall 28 percent between the end of 2012 and 2014.
FLSmidth - which is also the world's leading builder of cement factories - scrapped plans to sell its building materials unit Cembrit as it was not possible to "reach a satisfactory sales price".
