JB/T 5161.1-1999 Pellet feed pressing machine types and basic parameters

JB/T 5161.1-1999 This standard is a revision of JB/T 7882-99 "Types and basic parameters of pellet feed presses". The main technical content changes are as follows: - The model number representation method is changed from 93KW(L)H(P)-□ to 9KW(L)H(P)-□. This standard specifies the type and basic parameters of presses that press powdered feed into hard pellet feed and block feed. This standard applies to pellet feed presses. This standard was first issued on March 31, 1989 and was adjusted to JB/T 7882-95 in April 1996.

This standard specifies the types and basic parameters of presses (hereinafter referred to as presses) for pressing powdered feed into hard pellet feed and block feed.
This standard applies to pellet feed presses. 2 Types
Pressing machines are mainly divided into three types:
a) horizontal ring die;
b) vertical ring die;
c) vertical flat die.
Note: This standard does not temporarily stipulate other types. 3 Basic parameters
3.1 The main parameters of the press are the main engine matching power, that is, the main motor power. 3.2
The basic parameters should comply with the provisions of Table 1. The method for determining its productivity is shown in Appendix A (Suggested Appendix). Table 1

A1Feed formula used in the test
A unified feed formula should be used in the test. JB/T5161.1-1999
Appendix A
(Suggestive Appendix)
Method for determining the productivity of the press
Corn flour or wheat flour accounts for 60%, oilseed cake meal accounts for 10%, bran or rice bran accounts for 30%, and other oil lubricants and binders such as molasses shall not be added.
A2 The aperture of the die used in the test
The aperture of the die used in the test is Φ5mm. A3 Determination of productivity
Before the measurement, the die of the press can be run-in, and the running-in time shall not exceed 24h. At the outlet of the press, take the pellet feed once every 5min, and each time for no less than 1min, then weigh its mass, do it 5 times in total, calculate according to formula (A1), and find the average value. 60,w(1-H)
T. *(1-15%)
Where: E is the hourly productivity, kg/h-the mass of pellet feed taken each time, kg; T. ---the time of taking the pellet feed each time, min; H, ---the average value of the actual relative moisture content of the pellet feed, %. A4 Determination of the moisture content of pellet feed
At the outlet of the press, take about 50g of pellet feed every 5min, and take it 5 times in total. Put the pellet feed into aluminum boxes respectively. Weigh its mass immediately, dry it at a constant temperature of 105℃ until the mass remains unchanged, and weigh it again (weighing accuracy ±0.1g). Calculate the moisture content according to formula (A2) and find its average value.
