Can olive pomace be used for making briquette2021-10-25T13:45:33+08:00

Yes, the olive pomace can be used for making briquettes after it is dried.

What are the wearing parts of sawdust briquette machine and is it difficult to repair?2021-10-21T15:21:49+08:00

The vulnerable parts of the sawdust briquette machine are the propeller screw and the forming sleeve.

For staff who are new to charcoal production, do not master the forming principle of the sawdust briquette machine, the repair of the screw propeller is somewhat difficult. But after many repairs and mastering the main points and techniques of repair, there is no difficulty. You can refer to the article in our blog.

The wear of the forming sleeve is not as severe as that of the screw propeller, but it is not easy to repair by hand. Generally, replace the new sleeve directly after wear.

The maintenance cost of equipment per ton of product is about 3$. If you do not master the maintenance technology well, it is normal for the direct cost to increase several times, and the indirect cost is even greater (for example, the equipment can not work normally and cause the waste or stop production).

No need to add any adhesive for making sawdust briquettes2021-10-14T14:04:44+08:00

Biomass raw materials contain a large amount of lignin and cellulose. The heating ring of the briquette making machine generates high temperature to soften the lignin and increase the viscosity. Under the combined action of the screw propeller and the mold, the raw material is compressed into a dense biomass briquette. The whole process does not need to add any adhesive.

Binder for making charcoal briquettes2021-10-09T14:27:22+08:00

The common binder or adhesives for making charcoal briquettes is corn starch, tapioca starch, etc. Starch needs to be gelatinized and mix evenly with charcoal powder. 100kg charcoal powder mix with 3-5kg gelatinized starch.

Crop straw is not suitable for making charcoal2021-10-09T14:14:55+08:00

The calorific value of fuel rods produced from crop straw and sawdust is different. Generally speaking, the calorific value of carbonized straw fuel rods is 1/4 less than that of sawdust fuel rods. Therefore, straw fuel rods are not suitable for further carbonization. But it is a substitute for fuelwood and coal. It is suitable for heating, hot water boiler, greenhouse heating, or ordinary life fuel.

Hardwood for making high quality charcoal2021-10-09T14:00:38+08:00

Both hardwood lumps and sawdust are good materials for making charcoal. Hardwood is a broad-leaved tree with a hard texture and high density, such as oak, birch, beech, oak, sandalwood, mahogany, hard maple, alder, boxwood, wenge, and so on.

The difference between machine-made charcoal and natural wood charcoal2021-10-08T10:49:29+08:00
  1. Environmental protection: Machine-made charcoal is produced from the waste of bamboo and wood processing, turning wastes into treasure. The production of natural wood charcoal requires cutting down trees and destroying the ecological environment.
  2. High calorific value: The fixed carbon content of machine-made charcoal is about 80%, and the calorific value is 7500-8000kcal/kg. The fixed charcoal content of raw charcoal is low, with a calorific value of about 6500kcal/kg.
  3. Clean: When the machine-made charcoal is burned, there is no smoke, no sparks, and the residual ash will naturally fall and not float during the combustion, and the ash content is low, about 3%-6%.
  4. Machine-made charcoal has a uniform shape and size, and a hollow structure, which is conducive to burning and use.
  5. The moisture of machine-made charcoal is low, within 5%. Ordinary charcoal has a larger water content.
  6. Machine-made charcoal has the advantages of no chemical substances, no toxicity, no peculiar smell, no pollution, and a long burning time.
