Mezcladora doble eje horizontal

The SICOMA double horizontal shaft mixer will achieve excellent mixing quality in all types of concrete concretes
in the most efficient and fastest way with the maximum saving of cement. It will maximize your productivity and
reduce your cost per cubic meter. Ideal as a central mixer of high productions from 40 to 360m3 / h.

Galletti Ibérica
QUALITY SYSTEM

The Manufacturing Procedures used for all SICOMA Mixers have been compliant with the Quality Requirements of ISO 9001 since 1995 and have been updated and approved by CERMET since 2009 as compliant to ISO 9001:2008.

Galletti Ibérica
3-D MODELLING

Since 1999 all Mixers are designed and constantly improved with the use of three-dimensional modeling softwares.

Galletti Ibérica
CNC MACHINE CENTER

The steel fabrication of the mixer tank is machined with a CNC boring machine to guarantee the perfect alignment and parallelism of the mixing shafts.

Galletti Ibérica
ASSEMBLY LINE

The Mixers are line assembled giving very short lead times due to the high level of standardization.

PATENTS

The Shafts´Seals as well as other particular features are protected by International Patents. Twin shaft compulsory mixers MAO

EXTRA-RIGID TANK

The stiffened frame of the tank eliminates the risk of deformation during the transport (also in container) as well as during the full load operation and guarantees the correct planarity of the shafts’ seals. The metal frame for aggregates hopper and the scales can be laid right on the mixer without additional supports.

 

Galletti Ibérica
MIXING ELEMENTS

The mixer tank is lined with Ni-Hard Cast Iron of 530HB minimum hardness. The mixing arms, with a low profile to avoid material build up, are made in Spheroidal Cast Iron. The mixing blades are made in Ni-Hard Cast Iron of 530HB minimum hardness. The large number of blades, their position and their orientation guarantee the right combination between the effects of rolling and circulation of the material during the mixing action


Reductores   Los reductores del grupo de mezcla son de tipo epicicloidal. La primera reducción está realizada con una transmisión a poleas dotadas de un cardan homocinético para mantener la sincronización de las estanquidades. La baja velocidad de ingreso


AUTOMATIC LUBRICATION

The grease needed by the seal to keep the counter-rotating surfaces lubricated, is given by the automatic pump through a sequential distributor. It dispenses uniformly the actual necessary quantity of grease (0,09 kg/h) and guarantees a low grease consuption together with a low contamination of the mixing.




Galletti Ibérica
GEAR BOXES

The gearboxes of the mixing group are epicyclical type. The first reduction is carried out by a pulley transmission equipped with a constant-velocity universal joint to keep the shafts syncronised. The low input speed to the gearboxes allows the lubrication oil to work at low thermal load. The connection between the gearbox and the tank is made with the exclusive bell housing. This unique feature gives a better rigidity to the coupling between the gearbox and the tank and makes the assembly and the possible maintenance of the bearings and the seals extremely easy.

Galletti Ibérica
HYDRAULIC POWER PACK

The closing of the door is guaranteed by the pressure sensor included in the hydraulic circuit. In case of failure or blackout, a manual pump can be operated for the emergency discharge.

Galletti Ibérica
ALARM BOX

The mixer is equipped with several sensors: thermal sensors for the motors and for the gearboxes, level gauges for the oil of the geaboxes and for the hydraulic power pack, level and pressure sensors for the automatic lubrication system. Upon request, Sicoma can supply the Black Box, an electronic system that records type, number and duration of possible anomalies and alarms during the operation of the mixer. The same device can be programmed for the preventive maintenance.


Galletti Ibérica
DISCHARGE DOOR


The discharge door has a rubber seal that runs along its full perimetre. The eccentric rotation of the door sector guarantees that the rubber seal is always reached and compressed despite its wear and tear.

TOP COVER
.
The high top cover (500 mm) is equipped with two hinged hatches and does not have any post. It allows an easy access to the mixer for an accurate cleaning at the end of the shift or for both preventive and unscheduled maintenance resulting in a shorter shutdown of the plant.

Galletti Ibérica
NSPECTION PLATFORM

The inspection platform with stairs, included in the supply, is absolutely necessary for the safe inspection and maintenance of the mixer. Its effective modular design allows the installation to be extremely easy wihtout the need of any crane or winch.

Galletti Ibérica
SKIP HOIST

The loading skip for the aggregates is available for the MAO mixers up to the size 6000/4000. The hoist has two grooved drums on the same shaft. The skip cable has an anti free-fall block in case of cable failure while two limit switches constantly check its tension. Upon request, the double speed for ascent and descent is available.
 

Galletti Ibérica
BATCH FEEDING SYSTEM

Due to the particular reinforced structure of the tank, SICOMA Twin Shaft Mixers can be equipped with a Batch Feeding System stacked on the mixer using the fixing plates on the tank frame without the need of any additional metal structures. This system is composed by a supporting frame, Aggregates Holding Hopper, Cement Scale, Water Scale and Air Bag. Being everything is preassembled at the factory before the shipment, the time for the onsite assembly is extremely short

 

Galletti Ibérica
SWING OUT DRIVES(SWOD Option)

This unique option for SICOMA Twin Shaft Mixers was developed over the last years to make any maintenance to the shaft supports easier and faster . The full drive assembly (Motor, Pulleys and Gearbox) is hinged to the side of the mixer tank and it can be swung out easily without the need of cranes or any lifting device. In case of unplanned maintenance, the downtime for the plant is minimized, resulting in a extremely low maintenance cost.

Galletti Ibérica
HIGH PRESSURE WASH OUT

Two high pressure water pipes are placed above the shafts with as many nozzles as the number of arms. These spray bars are operated by a gearmotor and rotate so that the jets reach every spot for an effective cleaning. The washout has to be carried out at the end of each mixing cycle and the waste water is used for the next mixing.

Galletti Ibérica
LOW MOTION DRIVE

This option is based on an auxiliary motor which can rotate the shafts at low speed. By using a button switch, the mixer can be driven safely also with the inspection doors open. The cleaning as well as the regular maintenance (such as the periodic adjustment of the blades) are simplified and faster. The Control Panel for the Low Motion Drive is not included. We propose the Manual Control Panel of the Mixer which includes all devices to operate the Low Motion Drive.

Galletti Ibérica
MANUAL CONTROL PANEL

The mixer can be equipped with the Manual Control Panel which can operate the mixer in Manual Mode with the following buttons: Start/Stop of the mixer motors, Open/Close Discharge Door and Emergency Stop. This Panel can also operate the Low Motion Drive, if present.

Galletti Ibérica
BLACK BOX

The standard Alarm Box, usually supplied as a standard, can be replaced by the Black Box to record and process all signals coming from the several sensors and some signals from the control panel. The detection and record of the alarms have to support the operator in the maintenance of the mixer, by giving specific reminders on the regular maintenance set in the factory on the basis of the statistics on the mixers. The data can be downloaded using the two USB ports which allow the connection of memory devices (such as USB memory sticks) and the connection to a Personal Computer.

Galletti Ibérica
 
REDUCED DISCHARGE DOOR

The reduced size of the discharge door allows the use of a small discharge chute. As a consequence, the supporting structure of the mixer can be shorter compared with the standard twin shaft mixers.

Galletti Ibérica
DOUBLE DISCHARGE DOOR

The mixer can be equipped with two independent discharge doors to pour the concrete in two different places. One of the limitations of the twin shaft mixers is then overcome.

Galletti Ibérica
BOMB BAY DOORAll SICOMA 

Twin Shaft Mixers can be equipped with the Bomb Bay Door which allows the bottom of the mixer tank to be opened for nearly half of its surface. The discharge is extremely fast also in case of low slump concrete. This option is particularly important in case of RCC production and loading on dump trucks.
