2 VOLUMETRIC RAPIDMIX (CV) MODEL SPECS The Rapidmix has been designed t be ttally mbile and cmpletely self-cntained with its wn pwer surce. It is als cmpletely self erecting, using the hydraulic system t change the plant frm its travel mde int a fully peratinal plant in a few hurs. The Rapidmix is available in tw utput ptins f up t 400 r up t 600 tns per hur, depending n applicatin. Feed rates are fully adjustable fr the aggregate, cement and water systems. The plant is designed fr any mixing applicatin where a cement r binder needs t be mixed int a base material. The Rapidmix (CV) Plants are vlumetric cntinuus mixing systems. Vlumetric measurement (C) When materials are flwing cntinuusly and measured by vlume, by using a calibrated rtary valve, a variable speed aggregate belt, an adjustable calibrated gate pening, r a cmbinatin f these, s that a knwn, predetermined vlume f each ingredient is btained in a designated time interval, the methd f measurement is vlumetric. Cntinuus vlumetric measurement with multiple ingredients requires that the prper relatinship amng thse ingredients be maintained. It is this calibratin f speed, time, and vlume which prvides a smth cntinuus release f materials resulting in yur next hmgeneus mix. Rapidmix was develped t be a cst-effective methd fr mixing a wide range f materials in many frms f applicatin as listed belw: * Rller-Cmpacted Cncrete (RCC), fr pavement r dams. * Cement Treated Base (CTB), r Cement Stabilized Base. * Bentnite enriched sils fr lagns, waste landfills and prtective cell linings. * Sludge slidificatin fr hazardus and nn-hazardus waste. * Cntaminated sil stabilizatin. (Lead, Mercury, etc.) * Flwable fill. (Materials laded directly int mixer trucks and charged with water.) * Sil Cement.
