Final product treatment with anti-caking or anti-dust agents has become an integral part of
any fertilizer production. However not much attention is paid to the equipment required for
this purpose, leading to under use or over use of the agent, resulting in bad fertilizer
quality or waste of expensive anti-caking agents.
Fertiplant offers a well engineered system designed to satisfy diverse coating requirement.
The system consists of a
- The coating drum and
- Wax heating and spray system
- Feed system for clay
- PLC based panel for auto control of wax and clay feed
Coating drum : This is a rotary equipment supported on two tyres and
driven by a girth gear and pinion arrangement. The drum is normally not inclined, but has
small spiral flights to gently convey the material through the drum.
We normally provide a holding tank of one shift capacity, in which oil or wax is fed by the
client. The tank is made in Stainless Steel and is either electrically or steam heated.
Temperature sensors are placed at various levels to control the heating.
The filtering and pumping unit (dupleix) consists of a gear pump developing 3 to 4 bar
pressure. The desired flow rate is achieved by changing the rpm of the motor by a variable
frequency drive. This can be manually done, alternatively if material feed rate is available
(as 4 to 20 mA signal) then the rpm will be automatically set (in open loop) based on the
feed to rpm ratio which is linear in case of gear pump. This system is skid mounted.
