While it is possible to grind your weed without crushing the trichomes, doing so will result in a less potent product. Trichomes are the tiny, bulbous structures that produce THC, CBD, and other cannabinoids and terpenes, and they are easily damaged when crushed. This damage results in a loss of potency, so if you're looking to get the most out of your weed, it's best to avoid crushing the trichomes.
