AFROMIX recently supplied four large Cyanide Detox Agitators to a mine in Eastern Africa. These units are able to provide high mass transfer but still able to keep the solid suspended uniformly. Sufficient air is required with SO2 gas to destroy the cyanide complex.
Conventional gas dispersion systems offer good mass transfer but fail to keep the solids in suspension. The AFROMIX system makes use of a dual sparge system which can operate with air or oxygen. The sparges have been fitted with AFROMIX’s non-return valve system which prevents the sparges from blocking even at high percentage solids.
At the heart of every AFX peristaltic pump lies a heavy-duty peristaltic hose specially developed to work hand in hand with the pump roller technology installed in the AFX PUMP SERIES. We stock a comprehensive range of hose materials for each pump to be compatible with the unique chemical and abrasive characteristics of every application. A carefully designed and manufactured hose element is the single most vital component for the performance durability and efficiency of any peristaltic pump. To ensure a good pump you must have a good hose, and this is where AFX excels. Each hose we supply is built under stringent quality control measures, using high-quality, compounded rubbers, reinforced with four individual layers of braided nylon carefully set at optimum angles. Once cured, the outer diameter of each hose is precision machined to exacting tolerances ensuring a perfectly sized hose. An accurately sized hose ensures perfect compression, which eliminates internal slip (which reduces pump efficiency and allows for the abrasive slurries to prematurely destroy the hose).
Peristaltic pumps are by nature inherently pulsing in operation. Excessive pressure spikes and pulsations within the pump system can be extremely damaging to the pump hose and the process system.
The primary reason for hose failure is from cyclic fatigue (number of hose compressions). Pump hose failure is inevitable, but exactly when hose failure will occur is dependent upon many factors and may not always be at a convenient time when a technician is watching the pump.
Our extensive range of peristaltic hose pumps includes one of the largest pumps of this type in the world. Our 150mm pump has a maximum flow rate of 147m³/hr and can deliver pressures up to 10 Bar. These units are ideal for thickener underflow applications.
OPERATING PRINCIPLE
PUMP SELECTION
spreading from mining processes to chemical and agricultural testing laboratories as well as personal care and pharmaceutical laboratories, the need for this equipment is on the rise. Pilot plants and bench plants are small modular industrial systems, which are designed and implemented to generate information and understand particular behaviours during test or trial periods. This is usually done before building the large full-scale plant, which entails large capital outlays as well as major risks associated with the process. The use of the pilot or bench plants enables one to make a calculated and informed decision on whether or not to move forward with the full-scale operation. It equips the client with freedom to run tests accurately as well as change and modify procedures on the smaller scale.
BAFFLES AND BAFFLE COILS
Mounting bases and pedestals are critical in ensuring that the gearbox of the agitator is correctly aligned and mounted to the supporting beam structure. Our pedestals and bases are designed to significantly reduce the potential of twisting or flexing within the gearbox housing; which is often a common cause of some gearbox failures.
