Straw Cutter

Brief Introduction

TONY straw rotary cutter is a coarse crushing equipment specially used for processing baled straw materials. It can cut the bales into 3-5 cm finished products. It is mainly suitable for the crushing treatment of baled materials such as wheat straw, corn stalks, rice stalks, soybean stalks, tobacco stalks, peanut seedlings, sweet potato seedlings, cotton stalks, forage grass, seaweed and various branches. The processed materials can not only be used in the livestock breeding industry, but also be widely applied in feed mills, alcohol factories, lemon factories, food factories, etc., as raw materials

TONY straw rotary cutter adopts a disc-shaped rotary cutter rotor. Multiple moving blades are installed on the rotor, while the fixed blades are fixed on the machine body. During operation, the disc rotates at high speed, and the moving blades cooperate with the fixed blades to shred the straw. This type of rotary cutter has a simple and compact structure, occupies a small area, and is suitable for various working scenarios. It can handle straw bales of various shapes and sizes. The straw rotary cutter plays an important role in agricultural production and related fields.

The specifications of straw rotary cutters produced by different manufacturers vary, and so do their outputs. If you want to know more about this equipment, please feel free to consult TONY

Working Principle

The core of the straw rotary cutter is to cut the straw from its original state (bundled, bundled or scattered) into fragmented materials of the set length through the cooperation of the rotating knife and the fixed components.

TONY straw rotary cutter is generally composed of a frame, a rotary cutter, a feeding device and an overload protection device. Bundles or bundles of materials are directly fed into the rotary cutter, where they are chopped by the rotation of fixed knives, moving knives or high-speed rotating hammer blades, crushing wheels, etc. For example, the materials are blown out of the crushing chamber by the fan; Some bales enter the crushing cylinder, and the high-speed rotating crushing wheel breaks and crushes the bales. Some materials are gradually crushed under the impact of high-speed rotary hammer plates and the friction of the sieve plate, and then discharged through the sieve holes from the discharge port of the base under the action of centrifugal force

Main Parts

Structural composition

Frame part: Usually made of steel plates and welded together, it is structurally solid and supports the operation of the entire machine. It has the characteristics of being durable and easy to move, and can adapt to different working environments.

Rotary cutting part: This is the core component of the straw rotary cutter, consisting of a rotary cutter rotor, moving blades, fixed blades, etc. The rotary cutter rotor is equipped with sharp moving blades, and the moving blades cooperate with the fixed blades. Through the shear force generated by high-speed rotation, the straw is cut into pieces. The blades are generally made of wear-resistant tool steel, and some may also undergo tungsten carbide spraying and other treatments to improve the wear resistance and service life of the blades.

Feeding part: Common feeding methods include external chain feeding of gears, manual feeding, feeding by loaders or grab machines, and feeding by custom conveyors, etc. The feeding part can evenly and appropriately feed the straw into the crushing chamber of the rotary cutter, ensuring the efficient and stable operation of the rotary cutter.

Overload protection device: When the machine encounters an overload situation, such as excessive feed or hard straw, the overload protection device will automatically activate. It will cut off the power or make the transmission components slip, etc., to protect the machine from damage and prevent the motor from burning out or other components from being damaged.

Cutter Suitable Raw Materials

Crop straw

Corn stalks: They are common processable raw materials and have a large output in agricultural production. The straw rotary cutter can crush it and use it to make feed, biomass fuel, etc.

Straw: Round or square bundles of straw can be cut and crushed at one time, and can be processed into 3-5 cm crumpled strands. Both dry and wet straw can be used.

Wheat straw: It can also be crushed by a straw rotary cutter and can be used to make feed or as raw material for biomass energy.

Peanut seedlings: A by-product of peanut harvest, which can be crushed by a straw rotary cutter and used as a high-quality feed source.

Sweet potato seedlings: They can be effectively crushed and used in the production of animal feed.

Cotton stalks: Cotton stalks are also one of the processing objects of straw rotary cutters and can be applied in industries such as biomass energy.

Reeds: They can be crushed and processed and have application value in some specific industries.

Other plants

Seaweed: Some straw rotary cutters can crush seaweed.

All kinds of branches: It can handle branches with a diameter of less than 5CM. There are relatively few restrictions on the diameter, length, and moisture content of the branches, and the baling breaking rate is high.

Grape branches: They can undergo one-time crushing processing.

Cigarette rods: They can be crushed and processed by straw rotary cutters

TONY Straw Cutter In Pellet Production Line

TONY offers comprehensive straw biomass pellet processing equipment designed to convert baled corn stalks and other biomass feedstocks into pellet fuel.

The process begins with pre-treatment equipment—such as rotary cutter and hammer mill—to reduce the corn stalks into a sawdust-like consistency. If the moisture content is too high, a rotary drum dryer is used to lower it to the 10%–15% range. The material is then fed into a pellet mill for compression, resulting in high-quality biomass pellet fuel. Finally, the pellets undergo packaging; depending on customer requirements, they can be packed into small bags (15–50 kg) or large bulk bags (ton bags).

This outlines the basic process of straw pellet processing. It's important to note that during actual operation, safety regulations must be observed and related equipment must be regularly maintained to ensure production efficiency and product quality. For example, before starting the machine, ensure a small amount of material is left inside to prevent idling; and after completing a cycle, ensure that the roller bolts are loosened promptly.
