Mixing Systems


Paddle Mixers

Paddle Mixers or “Pug Mills” are custom designed to suit client applications using inhouse design software. Paddle Mixers are used for continuous mixing of products.

The paddles are adjustable and fitted with a locking mechanism that prevents accidental rotation of the paddle. The adjustment is used to fine-tune material feed rates and material retention times.

Paddle mixers can be fitted with spray nozzles for feeding liquids into the mixer. Water is often used on dust suppression or ash conditioning applications.

The drive arrangement is fitted with a flexible coupling to absorb any shock loading and the paddle mixers can be fitted with rotation sensors on one or both shafts. Both the driven and non-driven ends are fitted with stuffing glands to ensure a dust tight sealing arrangement.

The outboard bearings on the non-drive end are mounted on standoffs to allow easy access to the stuffing gland while the bearings on the driven end are housed inside the gearbox.

This effectively keeps the main bearings protected from dust by means of an additional set of oil seals.

Standard sizes include: 200, 300, 400, 500 and 600. Other sizes and configurations are supplied on request.

Ribbon Blenders

For special applications contact Techmatic to arrange for blending tests on specific materials. Maintenance is simple as the ribbon shaft can be removed from the trough without opening the bearings, stuffing boxes or removing the drive shaft. Stuffing boxes are fitted with four gland packing layers and can be supplied with air purging on request.

Optional extras include steam jacketing, stainless steel 304 or 316 construction, support stand, loading platform with stair access and pneumatic knifegate for the outlet.

Standard sizes include: 50 litre, 100 litre,
500 litre, 1000 litre, 2000 litre and 2500 litre. Other sizes manufactured on request.

Ribbon Blenders are manufactured using the “contra-flow” ribbon to ensure gentle and even mixing of product. Ribbon Blenders are primarily used in the food industry but have applications in a diverse spectrum of industry such as blending of cement, fertiliser, grease constituents and plastic masterbatch.

Laser profiling of supports and mounting brackets ensures consistent part size and ensures that drive shaft and ribbon shaft are correctly aligned during assembly. The robust trough is designed for structural rigidity allowing the ribbon blenders to be started in the filled condition without distorting the trough.
