Types and differences of straw briquetting machine

Straw briquetting machine is a professional equipment for briquetting crushed crop straw. Every harvest season, crops will produce a lot of crop straws after harvest. How to choose a suitable straw briquetting machine to press these straws into pieces? To solve this problem, it is necessary for us to understand the models and differences of straw briquetting machines.

With competitive price and timely delivery, Tiantai sincerely hope to be your supplier and partner.

There are two main types of corn stalk briquetting machines in China’s market: one is the flat straw briquetting machine, and the other is the vertical straw briquetting machine. The flat mode means that the die plate with the die is placed horizontally, and the vertical mode means that the die plate with the die is placed vertically, that is, the plane of the die plate is perpendicular to the earth. 

The main difference between them lies in the feeding method. The flat briquetting machine is naturally fed, and the material is sent to the barrel by the conveyor and naturally falls into the barrel by gravity and enters the pressing cavity. The vertical briquetting machine is forced to feed. The material is fed into the barrel by the conveyor, and there is a auger at the bottom of the barrel. The motor drives the auger to rotate through the reducer to force the material falling into the barrel into the pressing cavity. Through the above analysis, we can draw the following conclusions: the flat straw briquetting machine is suitable for briquetting broken materials, such as sawdust briquetting, peanut shell briquetting, furfural residue briquetting and so on. The vertical straw briquetting machine is suitable for briquetting long materials, such as corn straw briquetting, rice straw briquetting and cotton straw briquetting.

Efficient Straw Briquetting Solutions | C.F. Nielsen

As mentioned, there are many advantages to utilizing straw for energy production and other purposes. Straw products are seasonal - whether they are briquetted or not. Therefore, storing briquetted straw is much less space consuming than storing bales of straw. Also, as straw is an alternative to wood residue, some may find that it takes some time to establish a new market. At C.F. Nielsen, we have experience within various segments for straw, such as briquetting for heat and power, consumer logs, biogas and bioethanol and feed and toys for animals.  We are happy to share our knowledge and experience with our customers to ensure that they have the most success possible with our solution.

Furthermore, most types of straw such as wheat, barley, miscanthus etc. have a moisture level below 15%. This ensures a relatively low investment as equipment for handling straw is generally cheaper than equivalent equipment for wood. We have designed our plants so that the shredding, milling, dust extraction and handling fits our presses.
Our capacities start at 500 kg/ hour for straw briquetting.
In relation to this, we must also note the high ash content in straw, which creates more wear on the equipment. However, as experts, we at C.F. Nielsen have developed special accessories to remove stones and sand in the preparation of the straw. This ensures that our customers will have a resistant and high-efficiency machine
