1) Crusher: The crusher has the same generality and importance in the production of agricultural and animal husbandry as the rake. The crusher model has a wide range of power types. Feed crushing mainly includes crushing, grinding, crushing, sawing and chopping. Crushing for hard and crisp grain feeds, sawing and chopping brittle feeds suitable for large chunks, crushing and grinding for tough stocks. At present, mills produced around the country often use several methods at the same time.
2) Granulator: After the hay is crushed, the concentrate and other nutrient components are added to form a full-price feed, and the feed is made into a pellet feed. Granular feeds have the advantages of complete nutrition, good palatability, large feed intake for animals, fast feed intake, and high feed utilization. The whole set of equipment includes: pelletizers, steam boilers, grease and molasses addition devices, cooling devices, particle removal and screening devices. There are two types of pelletizers: flat die pellet mills and ring die pellet mills.
3) Briquetting equipment: hay is crushed, fine concentrates and other mineral elements are added, and then pressed into blocks to increase feed's nutritional value, feed intake, and digestibility. Increased density of grass blocks facilitates storage, transportation, and market circulation. Briquetting presses produce larger particles than the feeders, typically 25 mm 25 mm or 30 mm 30 mm square blocks, and cylindrical blocks 8-30 mm in diameter. The grass density is 0.6-1.0 g/cm3.
4) Field Drying Briquetting Complete Equipment: Field Drying Briquetting Complete Equipment includes mowing, picking and loading, transportation and drying briquetting machines, etc., to dry straw machine as the main equipment. This complete set of machinery can dry and press unregulated green grass into high-energy grass blocks. The main advantages of the field drying compacts are: they can minimize the nutrient loss of grass and obtain high-quality grass blocks. In the process of naturally drying hay in the field, the nutrient loss is generally 35% to 40%, while the field drying briquette does not require hay modulation, thus avoiding the impact of climatic conditions on harvesting operations, and the variety and content of grass. There is no special requirement for the amount of water, so the area has wide adaptability and is particularly suitable for areas with high moisture content in the forage, rain, and high air humidity. Although there are many advantages mentioned above, the cost of dry briquetting fuel is high, and there are certain limitations in popularization and application.

Visual Testing is the automated process of detecting and reviewing visual UI changes.Manually testing your app for across multiple browsers and devices is a tedious process, but you can accelerate it with automated visual testing that goes beyond pixel-by-pixel screenshot comparison.
In this webinar, you`ll see how you can easily avoid front-end bugs and visual regressions, as well as substantially increase coverage, by adding scalable automated visual testing to your existing Selenium and Appium tests running on the Sauce Labs cloud.
