The invention discloses a coal gangue ceramsite hollow brick preparation method, which comprises: 1, taking a certain amount of a ceramsite raw material, adding the ceramsite raw material into a crusher, crushing the ceramsite raw material into an irregular shape to enhance the viscosity of ceramsite, and purifying the flue gas generated during the crushing of the ceramsite raw material by using an air filter so as to obtain a purified flue gas; according to the device, when the product bricks generate cracks through the biological mixed powder, external water and air enter the product bricks, so that the biological mixed powder in the product bricks flows to gaps under the action of gravity to fill the gaps, and the product bricks are prevented from cracking. The blue-green algae bacterial spore powder in the biological mixed powder is in contact with air and water, and blue-green algae bacteria absorb carbon dioxide from the air to form calcium carbonate, so that the calcium carbonate coagulates the dry ceramsite crushed aggregates and the dry coal gangue crushed aggregates, cracks are repaired, the strength of the product is not reduced, and the safety problem is avoided.
本发明公开了一种煤矸石陶粒空心砖制备的方法，包括如下步骤，步骤一：取一定量的陶粒原料，然后将陶粒原料加入破碎机中，将陶粒原料破碎成不规格形状，增强陶粒的黏度，使用空气过滤器对陶粒原料破碎时产生的烟气进行净化，同时回收烟气中的陶粒粉尘，并将粉尘加入破碎好的陶粒碎料中，该装置通过生物混合粉末可以使产品砖在产生裂纹时，外界的水和空气进入产品砖内部，使产品砖内部生物混合粉末受重力作用流向缝隙，填充缝隙，生物混合粉末中的蓝藻细菌孢子粉末接触到空气和水，蓝藻细菌从空气中吸收二氧化碳，形成碳酸钙，这样碳酸钙就将陶粒碎料干料和煤矸石碎料干料凝合起来，使裂缝修补，不会使产品转强度下降，避免产生安全问题。
