HORIZONTAL RIBBON MIXERS
GIMAT's horizontal ribbon mixers are built of painted carbon steel or stainless steel AISI 304 or 316 with surface treatments making them suitable for this application.
The sheet metal used has considerable thickness to withstand the stresses of the mixing process which occurs rapidly and homogeneously thanks to the particular four-way ribbon and four cross-flows.
The available volumes are 190 -340 – 550 – 1000 -1500 - 2000 - 3500 usable liters with power ratings that vary depending
on the applications from 2.2 kW to 22 kW.
Different dimensions and capacities can nonetheless be evaluated and supplied.
Direct transmission by gearmotor with right-angled axles and an elastic joint having torsional flexibility as a function of the different load conditions ensures high output of the entire kinematic chain and quiet operation.
The inserted joint dampens vibrations and reduces the maximum impact load thereby creating an actual shock absorber for the rotary motion.
The gearmotor is controlled by a vector inverter to allow the gradual startup of the mixer even if it has a full load and to adjust the rotation speed according to the percentage of fullness.
Upon request, or in certain installation conditions, a solution can be provided with a gearmotor having right-angled axles and a chain transmission with a special bidirectional spring-action tightener to allow inversion of the rotation direction.
In this solution a hydrodynamic viscose joint is mounted for full-load startups and to protect the entire transmission.
The ribbon supports are made with oscillating bearings and dust seals on the heads; the seals are made with greasable puddening that can be fluxed from the outside with air.
The rotating gaskets have a special automatic system for recovering slack due to wear; this system allows the puddening to always work optimally, ensuring perfect tightness of the mixing ribbon shaft.
Therefore it reduces the number of manual adjustments required by traditional sealing systems while minimizing the bothersome and hazardous powder leaks that invalidate the duration of the bearings.
The upper lid has hatches for inspecting product load.
The load is emptied in the center through an unloading mouth that is operated manually or pneumatically.
Accessories:
• Electrical control board;
• Safety joint having a torque limiter function;
• Support frame for lifting the load from the ground;
• Load cell-weighing system that can weigh several different ingredients and formulas for managing the batching process in a precise and reliable manner;
• Fitted for loading or unloading with GIMAT flexible spiral or rigid screw systems;
• Customized versions to meet specific needs.
Upon request the system can be designed and built in conformity to ATEX Directive 94/9/CE
for Zone 22 and Zone 21 (outside the mixer) and Zone 20 (inside the mixer)
