Large steel plate pre-treatment shot blasting machine is an environmentally friendly equipment used for surface treatment of steel plates. It can remove rust layers and oxide scales on the surface of steel plates, increase the surface roughness of steel plates, and restore the original metallic luster of steel plates. So, should we choose mobile or through type for the pre-treatment of large-scale steel plate rust removal? In fact, each of these two devices has its own advantages and disadvantages. Below, the editor will give you a detailed introduction 1. Large through type steel plate shot blasting machine. This type of equipment has the advantages of good cleaning effect and production efficiency, but the disadvantages are high one-time investment cost and large floor area 2. Small mobile steel plate shot blasting machine. This type of equipment has the advantages of low one-time investment cost, small footprint, and convenient movement. The disadvantage is that we can only handle one side of the steel plate at a time, and when we want to clean the other side, we need to manually flip the plate, so the efficiency is slower than that of the through type. Even so, the mobile steel plate shot blasting machine can still cover thousands of square meters per day 3. Finally, let's compare the prices of these two types of equipment. The market price of the through type steel plate shot blasting machine is around 200000 to 400000 yuan, and the price of the mobile type is around 50000 to 100000 yuan. The specific price depends on the user's requirements, such as the larger the opening size of the equipment and the higher the production efficiency, which is definitely expensive. For example, if the equipment needs to be equipped with a spraying line, the cost will be higher, It's around the range of 1 million to 3 million
