Feed cooler machine

Feed cooler is one of the key machine in feed pellet production line.The counter flow cooler is used to cool the hot pellets,about 3-5 degreed higher than room temperature. With special coercive discharging system,it can be used in all kinds of raw material.The unique structure of the cooling system, relative movement between cooling air and materials, make the pellet forward step by step to cool.

The counter flow cooler working principle is adopted to cool the pellets with high temperature and moisture. Hot air touches hot pellets and cool air touches cool pellets so as to avoid the pellet surface crack caused by sudden cooling produced by direct touching between cool air and hot pellets.

The temperature of the pellet after cooling is not higher +3-5 ℃ than room temperature,and the cooling times is not less than 6-10 mins.

The counter flow cooler is mainly used in the cooling system of feed pellet production line or biomass wood pellets production line.

How Does a Wood briquette machine Work?

Ever think about what actually happens inside your machines?  It’s not magic that gets your wood briquettes, it’s a whole bunch of fairly simple mechanisms all working together to get the job done with as little work for you as possible.  You may have asked yourself, “how does a Wood briquette machine work, anyway?”  The answer can help you to choose the Wood briquette machine that’s best for you, as well as troubleshoot problems that may arise if you already own one.

Here’s How wood briquette machine Works:
Briquetting is a process that biomass is compressed under high pressure and high temperature. wood briquette machine uses a large screw to grind the biomass into briquettes that are of uniform composition. The self bonding of biomass to form a briquette involves the thermo-plastic flow of the biomass. The lignin content that occurs naturally in biomass is liberated under high pressure and temperature. Lignin serves as the glue in the briquetting process, thus binding,compressing the biomss to form into high density briquettes. During this process, no binder need to be used. So the ouput briquette is a type of clean and green fuel that is ideal for use in furnaces, boilers and open fires. The density of the briquettes is 1300kg/CBM.

It is specifically popular with the fields of particle board, fibreboard and paper mills and other industrial production and stock preparation section in wood manufacturing facility. A small drum chipper is the best raw material preparation plant laboratory equipment.Main raw materials for the wood chippers include cutting trails, logging residues (branches, twigs, etc.) and wood processing residues of raw materials (slab, slab, core logs, veneer waste, etc.), and non- agro waste raw materials (such as sugar cane, reed, bamboo, etc.) can be put into drum chipper as well.

Wood Chipper Applications
1. Necessary device in complete wood pellet plant.
2. Fixed chipper shredder and mobile chipper shredder are all available for home and industrial use.
3. Best equipment to clean up twigs and leaves in garden and to prepare for compost and pellet production.

A wood chipper is a machine used for crushing wood, generally tree logs or branches, into smaller wood chips. They are often portable, being mounted on wheels on frame suitable for various working environment. There are two kinds of wood chipper according to structure design: disc-type wood chipper and drum-type wood chipper. Disc wood chipper is usually used in paper making industries for it’s mainly process wood logs, while drum wood chipper can process both wood logs and agro stalks in various size.

By using a wood chipper,logs and small wood are cut into high quality chips with even length and uniform chip thickness. Our wood chipping machine is also suitable for the chipping of branches and twigs, straw, and planks. The chip lengths are different according to the requirements of paper plants, particular broad and fiber-board industries. In order to meet this need, Double Crane Machinery has improved different kinds of drum wood chippers recently, and the new type wood chippers have more advantages.

HOW DOES A HAMMER MILL WORK?

Hammer mills work on the principle that most materials will crush, shatter, or pulverize upon impact using a simple four step operation:

1.Material is fed into the mill’s chamber typically by gravity.
2.The material is struck by ganged hammers (generally rectangular pieces of hardened steel) which are attached to a shaft which rotates at a high speed inside the chamber.  The material is crushed or shattered by the repeated hammer impacts, collisions with the walls of the grinding chamber as well as particle on particle impacts.
3.Perforated metal screens, or bar grates covering the discharge opening of the mill retain coarse materials for further grinding while allowing properly sized materials to pass as finished product.
4.Hard, heavy materials such as glass, stone or metals exit the mill via gravity. Pneumatic suction us used to assist in the discharge of lighter materials such as wood, paper or other low bulk density products.

Varying the screen size, shaft speed or hammer configuration can dramatically alter the finished size of the product being ground.  For example, faster speed, a smaller screen, and more hammers result in a finer end product.  Each component can be changed individually or in any combination to produce the precise grind required.  All of this is determined by taking advantage of our free test grinding service.

Large Capacity Hammer Mills

Hammer mills are such equipment to reduce the size of wood chips to wood dust. When making wood pellets or briquettes, you possiblely will need one hammer mill if your raw material are wood chips,straws, stalk, tree branches and etc.

Straw, stalks or other biomass are shredded and pulverized by hammers over and over again till they are small enough to go through the screen. The finished size of the material can be set up and adjusted by using the appropriate changeable screens.

Double Crane Machinery has inexpensive hammer mills to work with small pellet presses. They are either powered by electric motor or diesel engine, or even both electric and diesel engine on one machine.

 Spare parts are hammers, mesh.

feed pellet processing line

Hammer mill consists of feed inlet , hammers, screen, rod and rotor. The hammers swing on the central rotor freely .The rotor spins at a high speed while material is sent into a feed hopper. The material is impacted by hammers and is thereby grinded and then falling through the mesh and the discharging port. It is widely used in foodstuff, chemical , fiber and other granular materials.

Horizontal Mixers

3.1.1 Continuous ribbon mixers

The continuous or "twin-spiral" mixer consists of a horizontal, stationary, half-cylinder with revolving helical ribbons placed on a central shaft so as to move materials from one end to the other as the shaft and ribbon rotate inside (Figure 2). Capacity can be from a few litres to several cubic metres. The speed of shaft rotation will vary inversely as the circumference of the outer ribbon; usually optimum between 75-100 metres per minute. Since material travel is from one end to the other, either end may be used for discharge. These mixers may be inverted for cleaning.

3.1.2 Non-continuous ribbon mixers

Non-continuous or interrupted ribbons are similar to the continuous ribbon mixers except that short sections called "paddles" or "ploughs" are spaced in a spiral round the mixer shaft. Action is different from that of continuous ribbon mixers, and may be more satisfactory for mixing liquids with dry solids. These mixers are made in a wide variety of sizes with travel of the outer diameter of paddles from 100 to 120 metres per minute.

Fig. 2 Continuous ribbon mixer

The transformation of a soft, often dusty feed into a hard pellet is accomplished by compression, extrusion, and adhesion. The general process involves passing a feed mixture through a conditioning chamber where 4 to 6 percent water (usually as steam) may be added. Moisture provides lubrication for compression and extrusion and in the presence of heat causes some gelatinization of raw starch present on the surface of vegetative ingredients, resulting in adhesion. Within 20 seconds of entering the pellet mill, feed goes from an air-dry (about 10-12 percent moisture) condition at ambient temperature, to 15-16 percent moisture at 80-90°C. During subsequent compression and extrusion through holes in a ring' die, friction further increases feed temperature to nearly 92°C. Pellets discharged onto a screen belt of a horizontal tunnel drier or into a vertical screened hopper are air-cooled within 10 minutes to slightly above ambient temperatures and dried to below 13 percent moisture.
