Product Description

Straw briquetting machine is a device that crushes and compresses biomass materials such as straw into strip fuel. After practice and continuous improvement, straw briquetting machine has been perfected. Straw briquetting machine has the advantages of high degree of automation, high output, low price, low power consumption, simple operation and no pollution to the environment. Therefore, straw briquetting machine can be widely used to press various biomass materials such as crop straw and small branches.

Biomass briquetting machine adopts a new compression mode, changing the vertical ring mold structure to a flat ring mode production, using the principle of its own rotating centrifugal force to evenly distribute the raw materials to all molding molds, avoiding the phenomenon of machine stuffiness caused by excessive concentration of local materials, and greatly reducing unit energy consumption. The equipment is specially designed for the characteristics of raw materials with high lignin and difficult molding. The multi-channel sealing design prevents dust from entering the bearing lubrication part. The unique mold design and the interaction principle of extrusion force, friction force and shear force between the rolling wheels make the material discharge smooth under the premise of high molding rate and higher production efficiency.

Working principle of Straw Briquetting Machine

The briquetting machine consists of a machine base, a protective cover, a feed port, a pressing wheel, a flat die, and a discharge port. Its working principle is: the material to be pressed should be crushed first, and its length should be 30-60mm, and the moisture content should be within the range of 15%-25%. The material is fed into the feed port of the briquetting machine through the feeding conveyor, and the material is evenly dispersed in the working area between the pressing wheel and the flat die. The main shaft rotates, driving the pressing wheel to rotate, and the material is forced to be squeezed out of the flat die in blocks and falls from the discharge port.

Features 

1.Large capacity

The capacity of the general thermal capacity biofuel is 30-50 kg/ m³,and the capacity of this product is 800-1300 kg/m³,about 20 times than the general thermal capacity biofuel.
2.High Heat efficiency
The heat utilization of biomass is only 10%-20%,and the combustion utilization rate can reach more than 40% after curing.
3.Clean and hygienic, non-polluting
Biomass-cured fuels can achieve“zero emission” during combustion.
4.Biomass resource is huge and easy to take

Advantages of Straw Briquetting Machine

The advantages of straw briquetting machines are mainly reflected in the following aspects.

First, it can make full use of crop waste resources. Crop waste such as straw is usually regarded as a waste and source of environmental pollution, but by pressing it into blocks, it can be converted into useful energy or raw materials. For example, the pressed straw blocks can be used as biomass fuel to supply energy production or industrial production.

Secondly, straw briquetting machines can reduce the volume of waste and improve the efficiency of storage and transportation. Because the pressed straw blocks are more compact and stable, they occupy less space and are easier to manage than bulk straw.

Finally, straw briquetting machines contribute to environmental protection and sustainable development. By effectively handling crop waste, the pollution and harm caused by its burning or open-air stacking to the environment can be reduced.

Application of Straw Briquetting Machine

Biomass briquette technology has brought vitality to waste energy and has become a new growth point in the field of waste utilization. It is widely used in coal-fired power plants, thermal power plants, waste incineration power plants, thermal power plants, cement plants and other enterprises, effectively accelerating the transformation and upgrading of the power industry, and gradually realizing the green and low-carbonization of power production, contributing to the national energy transformation.

ZZCHRYSO Straw Briquetting Machine – FAQ

A: It compresses crop residues – rice straw, corn stalks, wheat straw, and other agricultural waste – into dense, solid briquettes. Our ZZCHRYSO machine turns these bulky, low‑value materials into high‑density fuel that can replace coal in power plants, industrial boilers, and heating systems. It also reduces storage space by about 20 times.

A: First, the straw is crushed to 30–60 mm and moisture adjusted to 15–25%. The material is fed into the press chamber where a rotating main shaft drives press wheels against a flat die. The material is forced through die holes under high pressure, forming dense briquettes that drop out of the discharge port. No binder is needed – the natural lignin binds the particles.

A: It handles a wide range: rice straw, wheat straw, corn stalks, cotton stalks, peanut shells, rice husks, sugarcane bagasse, sunflower husks, and even small branches. The machine is specially designed for high‑lignin materials that are difficult to form.

A: Loose straw has a bulk density of only 30–50 kg/m³. After briquetting, the density increases to 800–1300 kg/m³ – about 20 times denser. This means much lower storage space and shipping costs. A truckload of loose straw becomes just 1/20 of its original volume.

A: The calorific value typically ranges from 3500–4500 kcal/kg, depending on the straw type and moisture content. The combustion efficiency is over 40%, compared to only 10–20% for loose straw. The briquettes burn cleanly with very low smoke and ash.

A: Four models: CRS‑2600A (75 kW, 1.5–2.5 t/h), CRS‑3500A (110 kW, 2.5–3.5 t/h), CRS‑4500A (132 kW, 3–4.5 t/h), and CRS‑6000A (185 kW, 4–6 t/h). All produce 32×32 mm square briquettes. Hole counts range from 52 to 120. Voltage is 380V/50Hz (customizable).

A: High output and low power consumption. Automated operation, simple maintenance. The flat‑ring design prevents clogging and reduces energy use. It turns agricultural waste into a valuable fuel, reducing environmental pollution from open burning. The briquettes have high density, long burn time, and near‑zero emissions.

A: Daily: check wear on dies and rollers, clean the feed inlet, remove any debris. Weekly: lubricate bearings and drive chains, inspect belt tension. Monthly: replace worn dies or rollers, calibrate pressure, check electrical connections. The machine has a multi‑channel sealing design to keep dust out of bearings. We provide a full manual and spare parts support.

A: Yes. They are widely used in coal‑fired power plants (co‑firing), biomass power plants, thermal power plants, cement plants, and industrial boilers. The briquettes help reduce coal consumption and carbon emissions, supporting green energy transformation.

A: Absolutely. It prevents open burning of straw, which causes severe air pollution. The briquettes burn cleanly with very low emissions. The process itself consumes little energy and produces no waste. Our ZZCHRYSO machine helps farmers and power companies turn waste into wealth while protecting the environment.
