A fertilizer spreader serves to provide nutrients through irrigation to enrich it. Its operation is quite simple: in principle it acts as a deposit for the fertilizer solution in which the product that we want to provide is diluted or dissolved through water. It has different outlets: one outlet, one inlet and another through which the internal pressure is relieved. In this article we are going to teach you how to assemble and operate a fertilizer spreader.

Materials needed to assemble a spreader

To assemble a fertilizer spreader and make it work, you will need a series of materials. In principle, all you will need are 2 reinforced polyethylene collars, a flexible PVC pipe, 2 male threaded polyethylene terminals, 1 female threaded polyethylene terminal, 2 extension polyethylene nuts and a manual mesh filter.

You will also need 2 polyethylene ball valves, two female threaded bag valves, a 60-liter 5-atm polyester fertilizer spreader, a PVC pressure pipe and a roll of Teflon.

How to assemble a spreader

1 The first thing we are going to do is mount two single socket collars. These are made up of two main parts: the base and the outlet, which can have different diameters.

2 We place the base at the bottom of the pipe. We put the sealing gasket on the inside of the outlet, ensuring that it does not come out of its seat, that it is well placed.

3 We now place the upper part of the collar on the pipe and proceed to screw to fix the piece.

4 Once this is done, with a drill and a metal or crown bit we drill the part that can be seen from the top of the collar. These collars can be installed on both PVC and polyethylene pipes.

5 We apply Teflon to all the inlets of the spreader: inlet, outlet and pressure relief.

6 Now we take our threads: in the case of having a thread-thread or polyethylene-polyethylene, we unscrew and screw. We screw the three bag valves into the intakes of our spreader: input, output and relief.

7 At the outlet we place the filter to ensure that no residue can clog the system.

8 Finally, we connect the inlet and outlet intakes with flexible pipes.

How our new spreader works

We throttle the water flow a little so that part of it is diverted to the spreader through the inlet. In the tank, the water will mix with the product and will come out of the outlet when we have opened it. The water, now enriched with the fertilizer, will return to the water flow passing through the outlet filter.

When we no longer have any fertilizer or fertilizer product left to add, we close the inlet and outlet valves and fully open the irrigation network valve. We also open the pressure relief valve so that it comes out.

As you can see, both the assembly and the operation of a fertilizer spreader is simple, but if you have any doubts, contact us. We will be happy to assist you.
