Today, talk about the crusher equipment, how to buy Jet Mill, below Shandong Alpa Powder Technology Co., Ltd., introducing the crusher equipment company explaining how to buy Jet Mill.
1. When selecting, first consider the purchased pulverizer as the raw material of crushing.
The pulverized cereal feed is mainly, select the top feeding hammer pulverizer; the crushed crumpled bran, the wheat feed, can choose the claw pulverizer; if it is required to be very versatile, if it is dominated by pulverized cereals, Take care of the pie valley and straw, select the tangential feed hammer slurry; mineral feed such as crushing shell, can be used as a seashell-free sutching machine; if used as pre-mixed feed, the granularity of the product is required. The fine can be adjusted according to the needs, and the special non-singulated pulverizer should be used.
2, generally crusher's instructions and nameplates, there is a rated production capacity (kg / h) of the pulverizer. However, attention should be aware of: (1) The rated production capacity is usually based on the state of pulverizing the corn, the water content of the water storage safety water (about 13%) and φ1.2mm aperture screen, because corn is Commonly used cereal feeds, screens of 1.2mm aperture are commonly used minimum sieves, at which point production capacity is small, which considers more common and difficult states in production. (2) The production capacity of the selected pulverizer is slightly larger than the actual production capacity, avoiding the production capacity of hammer wear, air-stop wind, etc., does not affect the continuous production supply of feeds.
3. The energy consumption of the crusher is very large. When you purchase, you must not consider energy saving. According to the standards of the relevant departments, the hammer pulverizer is not less than 48 kg per degree of electricity at a sieve of φ1.2 mm sieves with φ1.2 mm sieves. At present, the production of electricity production of domestic hammers has greatly exceeded the above provisions, and the high quality has reached 70 and 75 kg / degree.
4, the matching power of the pulverizer. The power kWh of the pulverizer is loaded on the machine manual and the nameplate. It tends to indicate that is not a fixed number but has a certain range. For example, 9FQ? 20 crusher, supporting power is 7.5? 11kw; 9fq? 60 crusher, supporting power is 30? 40kW. There are two reasons, one is that the power required for the varieties of the raw materials have a large difference, for example under the same operating conditions, the merits when the beam is smashed than pulverizing the corn.The rate is doubled. Second, when switching with different screens, the load of the pulverizer has a large impact. Some people think that the 9FQ? 60 crusher uses φ1. When the screen of the 2mm screen hole, the motor capacity should be 40 kW, when switching with a φ2mm screen, can be used for a 30 kW motor, and the φ3mm screen hole is a 22KW motor. Otherwise it will cause some degree of waste. The following empirical formula can be calculated using the hammer pulverizer. 1V = 6.4? 10.5Q (kW): 1V - Supporting power (kW) q - crusher rated productivity (T / H) 6.4? 10.5 is a coefficient, coarse pulverization taking a small value, fine Crushing takes a large value.
5. Considering the magenta production method should be considered. The pulverized finished product has three modes: self-weight falling, negative pressure suction and mechanical delivery. Small stand-alone uses self-weight delivery mode to simplify the structure. Most of the medium pulverizer has a negative pressure suction device. It is advantage that the moisture of the finished product can reduce the humidity in the finished product facilitates storage, increase the pulverization efficiency 10? 15%, reduce the dust level of the pulverizer. The agency is delivered to a crusher that is more than 2.5T is used.
6, the dust and noise of the pulverizer. Dust and noise in feed processing are mainly from the pulverizer. These two sanitation indicators should be fully considered when selecting. If there is noise and a crusher of noise and dust should be tested and dustproof measures to improve the working environment, which is beneficial to the health of the operator.
