1, according to production capacity choice. The crusher's rated capacity (kg/h) is contained in the manual and nameplate of the general crusher. However, several points should be noted: (1) The rated production capacity contained refers to the production in a specific state. For example, a cereal feed mill refers to the crushed raw material is corn, its moisture content is stored as safe moisture (about 13%), and the sieve aperture diameter is 1.2 mm. Because corn is a common grain feed, the 1.2 mm-diameter screen is the smallest screen commonly used. At this time, the production capacity is small, which takes into account the more common and difficult conditions in production. (2) The production capacity of the selected crusher should be slightly larger than the actual production capacity, otherwise it will increase the hammer wear, air leakage and other reasons leading to a decline in production capacity, affecting the continuous production and supply of feed. 2, according to crushed raw material selection. For crushing grain feeds, hammer mills with top feed can be selected; for crushing bran wheat feeds, claw mills can be selected; if the versatility is good, the crushing of grains is mainly required. , And take into account the pie and the straw, optional tangential feed hammer mill; crushed shells and other mineral feed, can use the shell without sieve crusher; if used as a pre-mixed feed pre-processing, require product crushed size Fine and can be adjusted according to need, should use special non-screen crusher. 3, according to the way of choice. There are three ways to smash the finished product through the discharge device: self-weight blanking, negative pressure suction and mechanical transport. Small stand-alone use more self-heavy materials to simplify the structure. Most of the medium-sized pulverizers have a negative pressure suction device, which has the advantage of absorbing the moisture of the finished product, lowering the humidity in the finished product, facilitating the storage, improving the crushing efficiency by 10-15%, and reducing the dust-generating degree of the crushing chamber. 4, according to the matching power selection. Both the machine instructions and the nameplate contain the kilowatts of power of the motor for the crusher. It often shows not a fixed number but a certain range. For example, 9FQ-20 type crusher, supporting power is 7.5-11 kilowatts; 9FQ-60 crusher, supporting power is 30-40 kilowatts. There are two reasons for this. First, there is a big difference in the power required when the raw materials are crushed. For example, under the same working conditions, the smashed sorghum is twice as powerful as the crushed corn. The second reason is that the load of the crusher has a great influence on the use of different screen holes. Therefore, when the 9FQ-60 crusher uses a sieve with 1.2 mm mesh, the motor capacity should be 40 kW; when using a sieve with a 2 mm mesh, a 30 kW motor can be used, and a 3 mm diameter sieve can be used. For a 22 kw motor, otherwise it will cause some waste. 5, according to energy-saving options. According to the standards of the relevant authorities, when the hammer mill uses crushed 1.2 mm sieves for corn, the output per kilowatt should not be less than 48 kilograms. At present, the output per kilowatt-hour of the domestic hammer mill has greatly exceeded the above-mentioned regulations, and the quality has reached 70-75 kilograms per kilowatt-hour. 6, according to the choice of dust and noise. The dust and noise in feed processing mainly comes from the crusher. The two environmental sanitation indicators should be fully considered when selecting a type. If a grinder with high noise and dust is chosen as a last resort, silencing and dust prevention measures should be taken to improve the working environment and benefit the health of operators.
