Cemented Rockfill – CRF

DESIGN

. Expertise Solutions

Cemented rockfill (CRF) plays an important role in the mining process, providing critical backfill support for previously-excavated mine areas. In applications where density and moisture content of CRF are critical to safe and compliant operation, reliable mixing and production machinery can make the difference.

DESIGN

. Surface Solutions

Based on off-the-shelf modular designs, SIMEM’s surface CRF plants have evolved from 50 years of batching and mixing experience. These plants are designed for compact transport, ease of installation, reliable operation and low total cost of ownership. But if standard designs aren’t what you are looking for, custom solutions, including colloidal mixer based systems are available.

DESIGN

. Underground Solutions

For deeper orebodies, situating the CRF plant underground often makes sense. Creative solutions are typically needed to deliver cement to the plant including pneumatic conveyance, isotainers, dry slicklines or even premixing cement/water in colloidal mixers. Expertise and experience matters. Our team has your solution.

DESIGN

. Portable Solutions

For small stopes or areas, the pastefill system just does not reach, semi-portable CRF plants put the backfill production right where it is needed. Choose from colloidal mixer slurry systems for use with run-of-mine waste, or MDC continuous mixers suited to crushed & screened aggregate. We custom tailor the solution to your specific requirements.

Grouting Plants – OTTERCRETE

DESIGN

. Ideal For Multiple Applications

A skid mounted series of grout plants featuring the VortiMix high-shear colloidal mixer which can be combined with agitation tanks, pumps, and full automation, making it ideal for a wide range of tunneling and mining applications

OTTERCRETE plants are used in a wide range of applications, including bi-component grout and hydrated bentonite production to support tunnel boring machine (TBM) operation and ground stabilization needs. OtterCrete plants produce lightweight cellular concrete, cement based grouts for jet grouting, deep soil mixing, water cut-off injection, slurry wall production, and more

DESIGN

. Vortimix Colloidal Mixer

VORTIMIX can rapidly mix cementitious grouts as low as 0.6:1
water:cement ratio (by weight). Combined with the optional
paddle mixer VORTIMIX can handle grouts as low as
0.45:1 w:c ratio. Ratios can even be lower with the addition
of super-plasticizers.

DESIGN

. Auxiliary Equipment

OTTERCRETE plants can be combined with a full range of auxiliary equipment, including containerized liquid storage and agitation tanks, silos, bulk bag unloaders, foam generators, and skid mounted pumping systems. This complete solution with standard capacities of 7.5m³/hr. (9.8yd³/hr.) and 10m³/hr. (13yd³/hr.), brings versatility and total cost convenience to projects worldwide.

DESIGN

. Pumping Systems

Pumping system design must consider many factors prior to operation. Matching a pumping solution for a specific project application requires extensive knowledge to ensure a pumping system performs as intended. Simem Underground designs and assembles complete systems guaranteed to perform. System types incorporate piston, peristaltic, progressive cavity, centrifugal, and air-diaphragm pumps. System come complete with associated power control units, instrumentation, and pipe cleaning assemblies. Systems are prepared for field connection as independent components, skid-mounted, or fully containerized.
