Pug­mills are in­stru­men­tal in adding mois­ture, ce­ment and other quarry ma­te­ri­als to­gether to pro­vide a ho­moge­nous road base ma­te­rial for the main roads and in­fra­struc­ture in­dus­tries. The Pre­ci­sion­screen Scor­pion Pug­mill is a very ver­sa­tile ma­chine that can be adapted to work with var­i­ous ap­pli­ca­tions for mix­ing.

Es­tab­lished in 1986, in Bris­bane, Pre­ci­sion­screen have been leading the way in the de­sign and man­u­fac­ture of mo­bile screen­ing, wash­ing, crush­ing and re­cy­cling equip­ment. The 30 years of ex­pe­ri­ence in the in­dus­try has gone into the Scor­pion Pug­mill de­sign.

The Scor­pion Pug­mill PLC+ is ca­pa­ble of pro­duc­ing up to 350 tonnes per hour (tph) and is ca­pa­ble of do­ing any main roads re­quire­ment. The stan­dard ma­chine is suit­able for OMC road base jobs and is also ca­pa­ble of do­ing ce­mentsta­bilised ap­pli­ca­tions (with the ad­di­tion of a ce­ment silo). Un­like other plants, the Scor­pion pug­mill has an el­e­vated pug head that dis­charges the pugged ma­te­rial from a 3.5m height.

This fea­ture avoids the is­sue of seg­re­ga­tion on the belt and makes it eas­ier to clean the main belt as the ma­te­rial is car­ried to the pug head dry. This ben­e­fit also al­lows trucks to be loaded di­rectly from the pug head and the op­er­a­tor has full con­trol of the ma­te­rial flow from the re­mote con­trol start/stop ac­tion in his loader.

The ag­gres­sive pug­head ac­tion en­sures a ho­mo­ge­neous mix of ma­te­ri­als. The pro­gram­mable logic con­troller (PLC) en­ables the op­er­a­tor to se­lect dif­fer­ent prod­uct mixes at the touch of a but­ton and the in­ter­face is easy to use, show­ing run­ning tph and wa­ter/ce­ment per­cent­ages. This fea­ture im­proves road base grading con­sis­tency, pro­vid­ing cus­tomers with a su­pe­rior ma­te­rial. The added blend bin with PLC al­lows us ease of op­er­a­tion and strin­gent con­trol on qual­ity, and mod­i­fied road base blends for sta­bil­i­sa­tion projects

There is also the op­tion to add an­other hop­per to blend dif­fer­ent road base prod­ucts to­gether. This can help add bot­tom end or plas­tic­ity to the road base at a con­trolled rate.

Queens­land busi­ness, Pre­ci­sion­screen, joined the Aus­tralian Made Campaign, be­com­ing an AMCL li­censee, with most of their Aus­tralian man­u­fac­tured prod­ucts now able to carry the fa­mous Aus­tralian Made Aus­tralian

Grown kan­ga­roo logo. The Scor­pion Pug­mill is man­u­fac­tured in Bris­bane and is reg­is­tered Aus­tralian Made. “We know our cus­tomers are look­ing for Aus­tralian Made ma­chin­ery that is man­u­fac­tured lo­cally and keeps Aus­tralian work­ers in jobs. The Aus­tralian Made logo is highly recog­nis­able and will help us stand out from the crowd,” Pre­ci­sion­screen gen­eral man­ager Paul Kerr says.

“We work in a very com­pet­i­tive en­vi­ron­ment and our point of dif­fer­ence is that a range of our prod­ucts are Aus­tralian Made, so it makes sense for us to leverage that fact by us­ing the Aus­tralian Made logo.”

Aus­tralian Made chief ex­ec­u­tive Ian Har­ri­son wel­comed Pre­ci­sion­screen as a li­censee.

“Aus­tralia’s rep­u­ta­tion for pro­duc­ing prod­ucts and pro­duce to high qual­ity and safety stan­dards is driv­ing sales in Aus­tralia, but we’re also see­ing a huge im­pact overseas – op­por­tu­ni­ties for ex­porters are boom­ing,” Har­ri­son says. “No doubt that’s what Pre­ci­sion­screen is see­ing for them­selves with their abil­ity to meet the needs of a di­verse range of clients.

Har­ri­son says the qual­ity and safety stan­dards for pro­duc­tion in Aus­tralia are some of the most strin­gent in the world and are part of the rea­son Aus­tralian man­u­fac­tur­ers have earned them­selves such stel­lar rep­u­ta­tions.


Pre­ci­sion­screen has poured 30 years of knowl­edge into the de­vel­op­ment of the Scor­pion Pug­mill mixer.
