What raw materials are more suitable for charcoal machine to make charcoal?　　Charcoal machine in the production of mechanism charcoal need to consider the issue of raw materials, so what kind of original to produce quality charcoal? From the structural composition of raw materials, there are two factors that determine whether they can become ideal raw materials for mechanism charcoal: how good or bad the fiber laps and how much lignin content. The former directly affects the density and mechanical strength of the molded bar, while the latter determines the maximum carbon content of the finished product. Comprehensive these two aspects of the following factors I take the advantages and disadvantages of raw materials in order for you to introduce a few: 1, larch. This is currently recognized as the most ideal mechanism of charcoal raw materials. Because of the lignin content of larch and moderate fiber lap knot compact, good density, so that it can be formed at a lower molding temperature and less extrusion pressure under the formation of high density, hardness and good molding rods.　　2, other pine wood, almost all pine wood is suitable for making mechanism charcoal. However, due to the differences in the nature of the composition, we will encounter different problems in the production. Such as some pine wood fiber knot is not ideal, making it difficult to form, for some manufacturers this is a difficult problem. For example, it is difficult to recover the fiber knot once it is damaged, even under higher molding temperature and extrusion pressure, it is difficult to get a good machine bar. This requires us to mix other raw materials to improve its bonding ability. In addition, there are some pine wood density is not very ideal, such as camphor pine, although it is pine and long growth cycle, but the wood is still soft, which makes us in the processing of this raw material is often insufficient to supply, resulting in molding rod cracks. This situation can be overcome by adjusting the screw pitch of the propeller or increasing the screw diameter. Due to the growth of geographic and growth cycle of different, a variety of pine composition ratio and structural characteristics are different, but if we can make a reasonable and accurate analysis of these, and take appropriate measures, pine is still very ideal raw materials.　　3, hard mixed wood. Hardwood species, such as birch, linden, elm, green willow, as well as most of the fruit trees and the south of the various types of bamboo can be categorized into this file. Its growth period is generally between pine and softwood, hard wood. Most of them can be used as raw materials for mechanism charcoal. However, due to the obvious differences in its composition and characteristics, many difficulties are often encountered when using it as a raw material for production. One of the obvious problems is the weak adhesion and capacity, for some of these raw materials simply mixed with other wood raw materials can not solve the problem. The use of hardwood production, the technical requirements are very high.　　4, crop waste. Some woody crop waste can be used as raw materials for mechanism carbon, but generally has a large ash, low calorific value, and other weaknesses. And the molding is more difficult, need high molding temperature and extrusion pressure, high technical requirements. However, if there is no ideal raw material for mechanism charcoal in your area in a wide range, and at the same time, the market demand for mechanism charcoal is very high, and you need to get it from the field, you can also consider utilizing the waste of agriculture for production. Sufficient and readily available raw materials and low costs are the advantages of such production. For example, a considerable number of barbecue restaurants buy mechanism charcoal not for the purpose of using it to grill food, but to take advantage of its long burning time to continue the fire, so that the guests in the non-meal time when the light can also be very quickly start a fire for grilling. In addition, the charcoal stove on the table of the barbecue restaurant is used to heat up the cooked food, so the heat requirement is not high, and the mechanism charcoal processed from agricultural waste is fully capable of doing the job. In fact, the use of this kind of mechanism charcoal is not limited to this. If there is an absolute advantage in technology, with first-class firing techniques, the calorific value and burning time of mechanism charcoal made from certain agricultural crops can be close to or reach the level of sawdust charcoal.　　In addition the size of the raw material should also be considered. Raw materials that are too large in size need to be crushed before they can be used, such as shavings and wood chips. Too small volume of raw materials need to be mixed such as slightly larger particles and higher density raw materials for production, such as wood ash, wood chaff, sanding powder, etc. These raw materials are very fluffy and light weight, it is difficult to automatically fall into the molding area, so it is necessary to mix other raw materials. The standard of measuring the volume of raw materials is to see whether they can fall into the molding area continuously, evenly and sufficiently.
