Introduction to Crushing Mixer

Introduction to Crushing Mixer

The crushing and mixing machine is a feed processing equipment that integrates the functions of crushing and mixing. It is mainly used to crush large raw materials (such as grains, meal, forage, etc.) into small particles or powder and mix them evenly with other raw materials. It is suitable for the production of feed for livestock and poultry, aquatic products, pets, etc.

Core function

(1) Crushing function
Applicable raw materials: Grains (corn, wheat, sorghum), cake meal (soybean meal, rapeseed meal), forage, block feed, etc.

Crushing method:

Hammer crushing: High-speed rotating hammer pieces strike the raw materials, breaking them into small particles (suitable for harder materials).

Toothed disc crushing: Materials are crushed through the shearing action between the rotating toothed disc and the fixed toothed disc (suitable for fibrous raw materials).

Roller crushing: Crushing through the squeezing of one or more pairs of rollers (suitable for softer or tougher materials).

Adjustable crushing particle size: By replacing the screen or adjusting the gap between the hammer pieces, the size of the crushed particles (such as 2mm, 4mm, 6mm, etc.) can be controlled.

(2) Stirring function
Uniformity of mixing: Mix the crushed raw materials with other powdered or granular feeds to ensure the uniform distribution of nutrients.

Stirring method:

Paddle type stirring: The high-speed rotating paddles drive the material to mix (suitable for dry powder mixing).

Helical ribbon stirring: Helical blades drive the material to circulate and mix (suitable for materials with high viscosity or containing liquid additives).

The mixing time is controllable: By adjusting the rotational speed and stirring time, ensure the uniformity of the mixture (CV value ≤5%).

Multi-functional expansion

Premixing function: Some models can add trace additives (such as vitamins and minerals) to achieve initial premixing.

Automatic weighing and feeding: Equipped with a weighing system, it enables precise feeding of raw materials in proportion.

Dust removal system: Reduce dust flying and improve the working environment.

Intelligent control: Controlled by PLC or touch screen, parameters such as crushing particle size, stirring time and rotational speed can be set.

Application scenarios

Livestock and poultry feed factory: Crush raw materials such as corn and soybean meal and mix them with other ingredients.

Aquatic feed factory: Crush raw materials such as fish meal and shrimp shell powder for the production of fish and shrimp feed.

Pet food factory: Crush meat and grains to produce dry pet food or snacks.

Self-mixed feed in livestock farms: Small-scale livestock farms use crushed corn, bran and other raw materials and mix them to make their own feed.

Advantages and characteristics

✅ One machine for multiple uses: complete crushing and stirring simultaneously, reducing equipment input.
✅ Improve feed utilization: The crushed feed is easier to digest and absorb, improving the efficiency of farming.
✅ Mix evenly: Ensure that nutrients are evenly distributed and avoid nutritional imbalance in animals.
✅ Strong adaptability: can handle a variety of raw materials, suitable for different aquaculture needs.
✅ ENERGY-EFFICIENT: Optimize crushing and stirring processes to reduce energy consumption.

Common types

Type: Applicable raw material characteristics
The hammer type crushing mixer has a high crushing efficiency for grains, meal and forage, and is suitable for hard raw materials
The toothed disc crushing mixer has strong shearing force for fibrous raw materials (such as straw and forage) and is suitable for tough materials
The roller crushing mixer is suitable for the extrusion crushing of soft or tough raw materials and is applicable to materials with a high fiber content
The double-shaft paddle mixer has a high uniformity of dry powder mixing and is suitable for premixes

Purchasing suggestions

Select the crushing method based on the characteristics of the raw materials (hammer type for hard materials and toothed disc for fibrous materials).

Select the equipment specifications based on the production volume requirements (500kg/h can be chosen for small-scale breeding farms, and 5-10 tons /h for large-scale feed mills).

Consider whether automatic control is needed (PLC control can improve production efficiency).

Inspect the dust removal and noise reduction design (to reduce dust and noise pollution).

Summary

The crushing and mixing machine is a key equipment in feed processing and breeding production. It can not only crush large pieces of raw materials but also mix them evenly. It is suitable for the production of various feeds for livestock, poultry, aquatic products, pets, etc. Its multi-functionality, high efficiency and adaptability make it an essential equipment for modern feed mills and breeding farms.
