Grinding sludge press

Efficient processing of grinding sludge

Our grinding sludge press forms briquettes from grinding sludge, recovering expensive cooling lubricants, such as oil or emulsion, in the process. These may actually account for more than 50% of the starting material.

The special briquetting technique used for grinding sludge is based on a special construction, developed by RUF, which has been technically adapted to deal with this particularly abrasive material. Due to its compact structure, the grinding sludge press can easily be incorporated into existing production processes and is suitable for 24h operation.

Advantages

  • Recovery of expensive cooling lubricants – oil or emulsion
  • Reduction in the amount to be disposed of
  • Savings in logistics and transport
  • Compact construction
  • More than 35 years’ experience

Briquetting grinding sludge – recovering cooling lubricants

In addition to the recycling of grinding sludge, the recovery of cooling lubricant also results in significant savings. Costs are cut to a considerable degree thanks to the reduction in the amount of grinding sludge to be disposed of. Grinding sludge briquettes may also be classed as “non-hazardous waste”, although the agreement of the local authorities needs to be obtained.

Briquetting ensures a more sustainable, cleaner workplace. Depending on customer requirements, we offer grinding sludge presses for throughputs between 40 and 350 kg per hour.

“The RUF ma­chines have been work­ing very re­li­ably since their com­mis­sion­ing. They are well-en­gi­neered and highly rec­om­mend­able.”

Johann Dietl Head of CNC man­u­fac­tur­ing at Zoll­ner, Ger­many

"We are thor­oughly sat­is­fied with this equip­ment and are con­sid­er­ing an ex­pan­sion of its use."

"This is the per­fect so­lu­tion to our han­dling and space prob­lems. And the waste alu­minium in the com­pact bri­quette shape – largely cleaned of the cool­ing lu­bri­cant emul­sion – achieves a higher profit when sold on ." 

Markus Weber Pro­duc­tion Leader GFC Antrieb­sSys­teme GmbH, Ger­many

"The bri­quet­ting sys­tem works com­pletely with­out prob­lems and had al­ready amor­tised it­self after two years.”

“We are very sat­is­fied with the RUF Bri­quet­ting sys­tem.  The in­vest­ment has def­i­nitely paid off.” 

Georg Reuss Ex­ec­u­tive Georg Reuss, Ger­many

"First and fore­most I am im­pressed by the good price-per­for­mance ratio, the qual­ity and the re­li­a­bil­ity of the ma­chines. Be­sides I truly ap­pre­ci­ate the ex­cel­lent per­sonal re­la­tion­ship I have ex­pe­ri­enced with the fam­ily busi­ness and their Se­nior Di­rec­tor Hans Ruf from day one."

"The RUF bri­quet­ting press has been gen­er­at­ing prof­its since day one, thanks to its good price-per­for­mance ratio, an ap­pro­pri­ate fi­nanc­ing plan and the sav­ings it makes pos­si­ble."

Lena Kozmenkova Ex­ec­u­tive SIA RMP, Latvia

"Our col­lab­o­ra­tion with com­pany RUF has started in 2002 and has been suc­cess­ful through all these years. RUF is not just a world known ma­chin­ery pro­ducer name and the leader in bri­quet­ting tech­nolo­gies mar­ket. RUF is your trust­ful busi­ness part­ner as it has been a re­li­able and sup­port­ing part­ner for us dur­ing both – pe­ri­ods of the sales peaks and dur­ing mar­ket de­pres­sion. It’s our luck to have the same busi­ness phi­los­o­phy with our main busi­ness part­ner – the RUF com­pany. When both of you have the same aim, you achieve it faster!" 

Wayne Carracher Man­ag­ing Di­rec­tor Re­cy­cling Tech­nolo­gies Group Pty Ltd Aus­tralia

"We do not have one un­sat­is­fied cus­tomer with a RUF ma­chine – and we have sold some 40 sys­tems here in Aus­tralia and New Zealand. That in it­self speaks vol­umes for the RUF com­pany and its equip­ment. In our opin­ion the RUF bri­quette press can­not be matched from a per­for­mance basis. Al­though it is more ex­pen­sive than most com­pet­ing ma­chines from a cap­i­tal cost point of view, the on­go­ing trou­ble free per­for­mance and main­te­nance of the RUF ma­chines put them well ahead of the op­po­si­tion."

Frequently Asked Questions

How long does it take for the purchase of a briquetting press to pay for itself?

Amortisation periods can be less than three years, in certain cases even less than 1 year. However, the amortisation period depends on the material to be made into briquettes and the quantity. Thanks to the reduction in volume, costs for transport, storage and handling are cut. The amortisation period can be further reduced through the sale of the briquettes and the recovery of coolants.  

What are the price categories for the machines?

The costs of a briquette press depend on various factors, such as the starting material, required throughput and briquette density. Our experts will be happy to advise you on a one-to-one basis and can draw up a non-binding quote.

What is the smallest amount of chips that makes briquetting worthwhile?

Briquetting can be worthwhile even with very small quantities of chips. Briquette presses with a lower throughput should be considered here. Depending on the material, our systems can make economic sense in these cases too. Our specialists will be happy to advise you!
