Mixer

The OFEC Mixer is the key mixing equipment in organic fertilizer production lines, designed to uniformly blend fermented organic materials, conditioners, and micronutrients according to formulation ratios. We offer two models – the twin-shaft mixer and the disc mixer – suitable for continuous large-scale production and intermittent small-batch production respectively, meeting the mixing needs of organic fertilizer projects of all scales.

Product Overview

In organic fertilizer production, the uniformity of raw material mixing directly affects the quality consistency and application effectiveness of the final product. The mixer is one of the most important pieces of equipment used in the organic fertilizer granulation process. Proper mixing processes directly affect subsequent granulation results and final product quality.

OFEC provides two types of mixers – the twin-shaft mixer and the disc mixer – tailored to different production scales, material characteristics, and process requirements.

Twin-Shaft Horizontal Mixer

The twin-shaft horizontal mixer features a dual-shaft design, with two parallel mixing shafts rotating synchronously in opposite directions to achieve efficient, uniform mixing. This model is particularly suitable for continuous large-scale organic fertilizer production, offering high mixing uniformity and efficiency.
It mainly consists of the following components:

A – Mounting Base: Supports the entire equipment
B – Housing: Welded from steel plates and sections, with a tight seal
C – Feed Inlet: Entry point for materials
D – Discharge Outlet: Discharges mixed materials
E – Inspection Door: Allows checking of equipment operation status
F – Mixing Assembly: Core working component, including left- and right-hand screw shafts and blades
G – Drive Gear: Transmits power
H – Pulley: Drive component
I – Motor: Power source
J – Reducer: Reduces speed, increases torque
K – Guard Cover: Safety protection

  • Mounting Base: Supports the entire equipment
  • Housing: Welded from steel plates and sections, with a tight seal
  • Feed Inlet: Entry point for materials
  • Discharge Outlet: Discharges mixed materials
  • Inspection Door: Allows checking of equipment operation status
  • Mixing Assembly: Core working component, including left- and right-hand screw shafts and blades
  • Drive Gear: Transmits power
  • Pulley: Drive component
  • Motor: Power source
  • Reducer: Reduces speed, increases torque
  • Guard Cover: Safety protection

Working Principle

The motor drives two parallel mixing shafts to rotate synchronously in opposite directions through the reducer. Specially designed mixing blades are mounted on the shafts. After material enters the housing through the feed inlet, the counter-rotation of the shafts and the pushing action of the blades create intense convection, shearing, and diffusion movements within the housing – achieving uniform mixing in a short period of time.
The blades are made of wear-resistant, non-stick materials. The blade structure is reasonably designed and simple, making replacement easy after wear and ensuring a long service life.

Disc Mixer

The disc mixer features a vertical disc structure, using a rotating mixing disc and mixing arms to thoroughly blend materials. This model is particularly suitable for intermittent small-batch production and projects requiring frequent formula changes.
It mainly consists of the following components:

● A – Frame: Supports the entire equipment
● B – Mixing Disc: Core working component where mixing takes place
● C – Mixing Arms: Equipped with mixing blades for shearing and tumbling
● D – Motor: Power source
● E – Reducer: Reduces speed, increases torque

● Frame: Supports the entire equipment

● Mixing Disc: Core working component where mixing takes place

● Mixing Arms: Equipped with mixing blades for shearing and tumbling

Motor: Power source

● Reducer: Reduces speed, increases torque

Working Principle

Material is fed into the disc-shaped mixing vessel through the feed inlet. The motor drives the mixing disc and mixing arms to rotate – the disc carries material in circular motion while the arms shear and tumble the material, creating multi-dimensional mixing movements that achieve uniform blending in a short period of time.
The discharge outlet is located at the bottom of the disc. After mixing is complete, opening the outlet allows rapid discharge. The disc structure makes cleaning and formula changeover very convenient, suitable for multi-product, multi-formula production scenarios.
