BIG-MIX Solid Dosing Unit

Maximum profitability. Highest operational reliability. Greatest flexibility.

Our experience has taught us that every plant has its own unique requirements when it comes to capacity, substrate materials and conveyor technology.

The storage and dosing of difficult, long-fibrous substrates such as Grass silage, horses and farmyard manure or straw and hay plays an important role in many biogas plants. The BIG-Mix solid dosing unit is characterized by a large storage volume with a subsequent, prooven mixing and dosing technology with a vertical mixing screw. It is highly versatile for the most difficult substrates and characterized by its low energy consumption. Our BIG-Mix make sure you get a durable system with proven technology and individual adaptation possibilities.

BIG-Mix Typ 200/4000

 The BIG-Mix stands out due to the low amount of energy required for large feed volumes of difficult substrates. The distinctive feature consists of stainless steel push strips individually driven by hydraulic cylinders. These push strips transport the substrate into a connected mixing and dosing area. The material is processed and then transferred to subsequent conveyor screws by a vertical mixing screw. This push floor system allows for the easy processing of difficult substrate material, such as 100% grass silage, solid manure, green waste etc. Volume capacities of 35 – 210 m³ are available.

The push strips are driven by an electric hydraulic power unit, which is standardequipped with thermal monitoring and a low oil switch. The BIG-Mix comes equipped as standard with a PLC for controlling the push strips and the mixing and dosing area.

Drive of the stainless steel pushstrips

A standard-equipped, high-quality, ultrasonic sensor monitors the fill level in the processing and dosing
area. The push strips only continue to convey material into the dosing area when the level in that area falls below the adjustable level setting. This control significantly reduces the running times of the hydraulic power systems.

Vertical mixer all stainless steel

For preparation of the stored substrates, vertical mixing screws made of stainless steel are used as standard. The mixing screw can be fitted with stainless steel cutting blades to process the substrate more efficient. The processed substrate is given to a conveyor screw and thereby to the succeeding feeding thechnology.

For each of these challenges, we have exactly the right answer. With our customized and proven solid dosing units, we have the right solution fo each user.

Equipment variations and accessories

Access ladder

BIG-Mix access ladder

For a good and above all safe view into the BIG-Mix container, a galvanized, anti-slip ladder is available.

 

Automatic lubrication

Automatic lubrication

In order to automate the lubrication procedure, we offer a simple and cost convenient process for centralized and automated lubrication process.

Cover

BIG-Mix Cover

To reduce emissions and effects of the weather, the BIG-Mix can be equipped with a hydraulically operated cover. The cover is a robust stainless steel construction in segmental construction. Optional the operation of the cover via a radio remote control can be implemented.

 

Maintenance opening

BIG-Mix maintenance opening

On the facilitation of maintenance operations, we offer an optional inspection opening in the container sidewall.

 

Overflow protection

BIG-Mix overflow protection

In order to prevent the substrate to pass behind the container construction, special stainless steel segments may also be mounted on the top of the BIG-Mix (only pissible for devices without a cover).

 

Weighing system

BIG-Mix weighing system

For an accurate control of the loading capacity we focus on shearing force or pressure sensors. Different display units, optionally coupled with a well-readable, alphanumeric display with double-row LEDs, provide high usability and a simple programming of the optimal dosage quantities. For the further processing of the data both analog signal outputs as well as Profibus interfaces can be be provided.

 

Replacement and Repowering

Which of our BIG-Mix Solid Matter Dosing Units is the optimal device for your system, results from individual requirements such as plant size, spatial conditions, type of substrates and their mixing ratio. For the individual wishes of our customers, we therefore offer 18 different model dimensions having different motorization and equipment types.
