Straw briquette machine is composed of feeding conveyor, compressor and discharger. The straw or forage grass to be pressed is fed into the feed inlet by the feeding conveyor, and the main shaft rotates to drive the press roller to rotate. After the rotation of the press roller, the material is forced to be extruded into blocks from the mold hole, and falls from the discharge outlet to make straw briquettes.

Straw briquette machine is a new industry with broad prospects and rapid development momentum. However, because there is no national unified product standard in this industry, the technical level of straw briquette machine industry is uneven. In order to pursue profits and reduce costs, some manufacturers have lowered prices at the expense of the performance and quality of straw briquette machines to promote sales, disrupting the market of straw briquette machines and increasing the difficulty for customers to buy high-quality straw briquette machines.

The mould of straw briquette machine has to bear huge mechanical stress and thermal stress in the working process. Therefore, the mold quality of straw briquette machine is very important. Therefore, it is necessary that the steel needed to produce the mould of straw briquette machine has extremely high hardness, strength, wear resistance and toughness, as well as good high temperature resistance, thermal fatigue stability, thermal conductivity and corrosion resistance. A good mould of straw briquette machine is processed by high-quality numerical control, with high cost, uniform tool texture and smooth surface. However, in common mold processing, the texture of tools is uneven and the surface is rough.

The raw materials used in the mould of straw briquette machine, the manufacturing quality, structural design, technical parameters and feeding conditions of the mould are all factors that affect the service life of straw briquette machine, and they are also aspects that customers need to pay attention to when purchasing and selecting straw briquette machine.

So how should we judge the quality of straw briquette machine mould:

1. Look at the surface.

High-quality die surface is smooth and flat, and the tool texture is uniform; The inferior mold has rough surface and poor texture.

2. Look at the shape.

The high-quality straw briquette machine, whose mold size is processed by a unified program, has high precision, and the consistency of processed products is unmatched by ordinary machine tools. The consistency of the molds ensures that the molding pressure is consistent, the machine is stressed evenly, and the interchangeability of each mold is ensured, which makes it more convenient for users to repair and replace the molds.

3. Look at the hardness.

High-quality straw briquette machine molds are made of special alloy steel through complex multiple heat treatment processes, and the hardness can reach Rockwell hardness of 60 degrees. All kinds of machining tools, including drills and taps, can’t cause any damage to them, so it is very difficult for biomass materials such as straw to wear the molds. However, the hardness of ordinary carbon steel die can only reach 45 ~ 50 degrees, which can be damaged by drill and tap, and the wear resistance is greatly reduced.

4. Look at toughness.

High-quality straw briquette machine die steel has been repeatedly forged before processing. Its molecular arrangement is more compact, its structure is compact, and its strength and toughness are 2 ~ 3 times that of ordinary carbon steel plate, which ensures that the straw briquette machine die can keep its original shape and not deform under long-term high-strength stress.

In the current situation, although the straw briquetting business has a broad market and prospect, it also faces many practical difficulties.
