New Wetmix System from SPEC MIX Words: Jeff FarmakesThe SPEC MIX D2W WETMIX continuous mixing system is designed to give the mason contractor control over the key elements that allow him to make a profit. For example, what does a masonry foreman do when he has to grout a CMU wall by the end of the day to stay on the GC’s schedule, but its 3 p.m., and the ready-mix truck delivering eight yards of core fill is an hour late? Does the foreman reschedule the grout pour for the following morning, or keep his crew onsite until the truck arrives, paying his crew overtime? Either way, the mason contractor loses both time and money — not an efficient solution to a common job site problem. The SPEC MIX D2W WETMIX allows a mason contractor to mix grout and mortar on site, whenever the crew needs the material. With an output rate at nearly eight cubic yards of grout per hour, the system will produce the material needed to efficiently keep a standard grout pump and masonry crew busy reinforcing a wall. The system also can be reloaded with SPEC MIX bulk bags as your team places the grout. The SPEC MIX D2W WETMIX can mix a 10-cubic-foot tub of mortar in less than 5 minutes with the push of a button. The system uses a unique array of specialized mixing paddles and agitators that fold and sheer the material to efficiently hydrate the dried aggregate, and mechanically work natural air into the material for maximum workability. It is no longer necessary to place a laborer at the mixing station to shovel sand or operate a silo; it can all be accomplished from the seat of a jobsite forklift with the use of a wireless remote control. The driver can place a tub underneath the mixer, push a button on the remote and drive away. The mixer automatically stops at the set time Control panels allow the operator to preset the batch size from as little as a five-gallon pail of material to a mud tub to continuous output, eliminating material waste by rightsizing batches to the required work. A specialized water pump panel allows the contractor to control the water-to-cement ratio of the material, making material testing virtually obsolete. The system runs on single-phase, 230-volt, 50-amp power. Its direct connection to the bottom of a SPEC MIX Silo eliminates any dust associated with mixing cementitious materials. The SPEC MIX D2W WETMIX also has a preset cleaning cycle that flushes the mixing chamber with water until it is clean, and then automatically shuts off.
