How to measure the pellet performance of briquette machine? Method for measuring the properties of briquette
Most industrial production requires burning coal to obtain a high-temperature production environment. In order to improve the combustion performance of coal, briquette is basically used. The briquette can better meet the needs of industrial production in terms of strength and durability.
But not all the briquette pellets pressed by the briquetting machine can meet the requirements, and their performance is easily changed by the adjustment of the equipment parameters. How to measure the performance of the briquette machine?
1. Pellet forming principle of briquette briquette machine
Driven by the motor, the pair of rollers of the briquette briquetting machine rotate in opposite directions at the same speed. When the material falls between the two pairs of rollers, it begins to be compressed at the junction. At this time, the material is compressed in volume between the corresponding two ball sockets. ; The rollers rotate continuously, the ball socket is gradually closed, and the forming pressure gradually increases. When the distance between the two ball sockets is minimum, the forming pressure reaches the upper limit.
Then the rollers are rotated to gradually separate the ball sockets, and the molding pressure decreases rapidly. When the forming pressure is reduced to zero, the pressed briquette begins to expand and break away.
2. Determination method of pellet performance of briquette briquette machine
(1) Cold strength:
Randomly select 10 briquette pellets and place them on the particle strength testing machine one by one for pressure feed test, record the pressure value indicated when each briquette pellet cracks, and calculate the average value, the unit is N/ball. The average error is valid in the range of +50N, and the ambient temperature is 25 degrees Celsius.
