Feed mill

Feed mill is mainly used for crushing a variety of feed and a variety of roughage, feed crushed to increase the surface area of the feed and adjust the particle size, increase the surface area to improve palatability, and in the digestive side is easy to contact with the digestive juices, which is conducive to improving the digestibility of the feed nutrients are better absorbed.

Function

With the new energy continues to develop, straw utilization has become one of the new projects, boiler injection, straw vaporization, fermentation processing, straw panels, straw return to the field, grass processing enterprises 'feed processing households, straw feed mills, pellet feed processors, bioelectric power plants, cattle, sheep feeders, straw carbon plant, density board, straw to make the door, straw charcoal, straw board, feed and many other fields. Straw utilization in many projects shows great potential for development. Qufu Xin green gold using the original two-stage crusher technology, can quickly all kinds of crop straw, twigs, cotton stalks, corn stalks, wheat straw, straw, peanut seedlings, groundnut seedlings corn, sorghum, dried groundnut, broken bean cake, dry bean straw, etc. No artificial holding material; artificial pre-processing more does not require the hand of the machine operator in the inlet hand-feeding, to overcome the past crusher feeding difficulties, danger, labor costs are too high efficiency and other shortcomings only to use the Stick pick; pitchfork turn; mechanical grass grasping machine whole bundle feeding, mechanized belt conveyor conveyor and other artificial; mechanical feeding methods. In a meter away from the hedge special rough crushing bin directly into the whole bundle of material into the crushing bin, through the straw automatic feeding, after rough processing automatically into the crushing room for the second crushing 'processing range of 1-30 mm, the length of the raw material is not limited, is the most advanced chaff powder processing equipment.

The crushing of feed materials is a very important part of feed processing, through the crushing of raw materials can increase the unit mass of particles of raw materials, large total surface area, increase the solubility of feed nutrients in the digestive fluid of the animal to improve the digestibility of the animal; at the same time, crushing the raw material particle size of the subsequent process (such as granulation, etc.) of the ease of use and the quality of the finished product has a very important impact; and, the size of crushed particles directly affects production costs, in the process of crushing raw materials and the quality of the finished product. Size directly affects the cost of production, in the production of powdered feed, crushing process of power consumption is about 50% to 70% of the total power consumption. The smaller the size of the crush, the more conducive to animal digestion and absorption, but also more conducive to granulation, but at the same time, power consumption will increase accordingly, and vice versa. China's total annual crushing and processing of more than 200 million tons. Feed mill as the feed industry's main equipment, feed quality,

Feed remuneration, the formation of feed processing costs is an important factor. Therefore, the proper mastery of crushing technology, the selection of appropriate crushing machine type is the feed production can not be ignored.

Type

Roller

It is a pair of relatively rotating cylindrical mill rolls to saw, grinding feed machinery, with high productivity, low power, easy to regulate and so on, mostly used in wheat milling industry. In the feed processing industry, generally used in the first process of secondary crushing operations

Hammer blade

It is a kind of high-speed rotation of the hammer blade to break the feed machinery. It is characterized by simple structure, high versatility, high productivity and safe use.

Tooth and claw type

It is a kind of machine which uses the high-speed rotating tooth and claw to break the feed, with the advantages of small volume, light weight, fine particle size and high working speed.

Main indicators

1, productivity: the hourly production capacity of kg / h

2, the amount of electricity products: the amount of products crushed per one degree of electricity consumption (kg / degree) This indicator measures the size of the several types of different types of crusher performance indicators.

3, fine crushing degree: the average diameter of the crushed feed particles, which represents the degree of crushing.

4, the determination of the degree of fine crushing:

GB5915-86 regulation method: the percentage of sieve on the material that K that:

K = sieve on the retention of the feed is important / samples in the * 100%

Take a sample of 100 grams in the national standard provisions of the motorized state shaking sifter sieve for 10 minutes in a row, will be the sieve on the retention of the feed layer weighing, and then calculate the K if there is no The above sieve can be used to sieve flour coarseness and fineness of the electric sieve sieving (or manual sieve for 5 minutes)

2) geometric mean particle size method

3) Taylor sieve (foreign) method: with the particle size coefficient (MF) and uniformity (MC).

Crushing method

Crushing is the process of external force to overcome the cohesive force between the body molecules and make them broken, and its basic methods are as follows.

1, crushing: mainly by high-speed running parts, the impact produced by the crushing, the method of high productivity, less heat, less gray powder is suitable for addition of brittle materials.

2, the quality of broken: the use of the two original discs carved with the hard surface of the tooth groove, and friction on the feed and broken, the advantage of its lower manufacturing costs, less power required, the disadvantage is that the mill out of the feed temperature is higher, more powder, fine crushing is not easy to control. Suitable for processing plastic material.

3, crushing: the use of two smooth surface pressure rollers, the same speed relative rotation, the feed crushed, commonly used in flattening barley and other feed, as a large livestock feeding purposes.

4, saw shredding: the use of two surfaces with teeth and different speeds of the mill rollers will be shredded materials, the advantages of which are easy to dig the coarseness and fineness of the system, the amount of hair potential is small, easy to keep, suitable for processing cereals, cakes and residues, and so on.

Selected according to the production capacity

General crusher instructions and nameplates, are contained in the crusher to determine the production capacity (kg / h), but should pay attention to a number of points:

1. Rated production capacity contained in the production capacity of a particular state of mind, such as cereal feed crusher, is the crushing of raw materials for the corn , its moisture content for storage safety moisture (about 13%), sieve aperture diameter of 1.2 mm. Because corn is commonly used cereal feed, the diameter of 1.2 mm aperture of the sieve plate is commonly used in the smallest sieve, at this time the production capacity is small, which takes into account the production of more generally have more difficult state.

2. Selected crusher production capacity should be slightly greater than the actual need for production capacity, otherwise it will increase the wear and tear of hammer blades, duct leakage, etc. leading to a decline in production capacity, affecting the continuous production and supply of feed.

Selected according to the crushing of raw materials

To crush grain feed, you can choose the top feed hammer mill; to crush bran cereal feed, you can choose the claw mill; if the requirements of the generality of good, mainly to crush grain, and taking into account the cake and grain and straw, you can choose to tangentially feed the hammer mill; crushing Shells and other mineral feed, shells can be used without sieve mill; if used as a pre-mixed feed pre-treatment, the requirements of the product crushed particle size is very fine and can be adjusted according to the needs of the special sieve mill should be selected, and so on.

Selected according to the discharge

Crushed finished product output through the discharge device there are three ways: self-weight drop, negative pressure suction and mechanical conveyance. Small single-machine mostly self-weight discharging way to simplify the structure. Most of the medium-sized crusher with negative pressure suction device, the advantage is that it can suck away the moisture of the finished product, reduce the humidity in the finished product and conducive to storage, improve the crushing efficiency of 10% to 15%, reduce the dust in the crushing room.

Selected according to the matching power

Machine manuals and nameplates are contained in the crusher matching motor power kilowatts. It often indicates not a fixed number but a certain range. For example, 9FQ-20 type pulverizer, supporting power for 7.5 kW ~ 11.0 kW; 9FQ-60 type pulverizer, supporting power for 30 kW ~ 40 kW. There are two reasons: First, the variety of raw materials crushed at the same time as the required power has a greater difference, for example, under the same working conditions, crushing sorghum than crushing corn power twice as much; Secondly, when changed to a different sieve, the crusher's load has a great impact. Therefore, 9FQ-60 type pulverizer using 1.2 mm diameter sieve hole sieve sheet, the motor capacity should be 40 kilowatts. When switching to 2 mm diameter sieve holes, 30 kW motor can be used, 3 mm diameter sieve holes for 22 kW motor, otherwise it will cause some degree of waste.

Choose according to energy saving

The energy consumption of the pulverizer is very large, and energy saving should be considered when purchasing. According to the standards of the relevant departments, the hammer chip crusher in the use of sieve diameter of 1.2 mm sieve crushed corn, the output per degree of electricity shall not be less than 48 kg. Domestic hammer crusher per kilowatt-hour output has greatly exceeded the above provisions, high-quality has reached 70-75 kilograms per kilowatt-hour. Crusher supporting power machine manuals and nameplates are marked on the crusher supporting motor power kilowatts. Marked power kilowatts is often not a fixed number but a range, such as 9FQ-20 pulverizer supporting power for 7.5-11 kilowatts; 9FQ-60 pulverizer supporting power for 30-40 kilowatts.

There are two reasons for this, one is the crushing of different varieties of raw materials at the same time the power required to have a greater difference, for example, in the same working conditions, crushing sorghum than crushing maize power twice as much; secondly, when the change of different sieve holes, the crusher has a great impact on the load. 9FQ-60 crusher sieve diameter of 1.2 millimeters of the use of sieve sheet, the capacity of the motor should be 40 kilowatts; change of 2 millimeters of the diameter of sieve hole, sieve sheet, motor capacity; change of Sieve diameter of 2 mm sieve, the motor capacity should be 30 kilowatts; change the sieve diameter of 3 mm sieve, the motor capacity should be 22 kilowatts, otherwise it will cause some waste.

According to the standards of the relevant departments, the hammer mill in the crushing of corn with a diameter of 1.2 millimeters sieve hole sieve sheet, the output per kilowatt-hour shall not be less than 48 kilograms. High-quality has reached 70 kilograms to 75 kilograms per kilowatt hour.

According to the dust and noise selection

Feed processing in the dust and noise mainly from the grinder. Selection should be given full consideration to these two indicators. If you have no choice but to choose a high noise and dust crusher, should be taken to muffle the noise and dust measures to improve the working environment, and is conducive to the health of the operator.

Instructions

1, long-term operation of the crusher, should be fixed on a cement foundation. If frequent changes in the workplace, the crusher and the motor should be installed in the machine base made of angle iron, if the crusher diesel power, should be made to match the power of the two, that is, the diesel engine power is slightly greater than the crusher power, and so that the two pulley grooves are consistent with the pulley on the same plane on the outer face.

2, after the installation of the crusher to check the fastening of the fasteners, if there is loose to be tightened.

3, to check whether the belt tension is appropriate, the motor shaft and pulverizer shaft is parallel.

4, pulverizer before starting, first hand rotor, check whether the teeth claw, hammer and rotor operation is flexible and reliable, there is no collision phenomenon in the shell, the rotor's rotating direction is the same as the direction of the arrow on the machine, the motor and the pulverizer lubrication is good.

5, do not casually replace the pulley, in order to prevent too high a speed so that the crushing chamber to produce an explosion, or too low a speed to affect the efficiency of work.

6, after the start of the pulverizer idling for 2-3 minutes, no anomalies before feeding work.

7, the work should always pay attention to the operation of the crusher, feeding to be uniform, in order to prevent blocking boring, do not overload for a long time. If you find vibration, noise, bearing and body temperature is too high, spraying material to the outside and other phenomena, you should immediately stop the car to check, troubleshooting before you can continue to work.

8, crushed materials should be carefully examined, so as to avoid copper, iron, stone and other hard objects into the crushing chamber causing accidents.

9, the operator should not wear gloves, feeding should stand on the side of the crusher to prevent rebound debris hit the face.
