Sand fault Solution: First, the sand is not in there when the material started running, if you do, then it will start pressure because the motor is too large to burn out the motor. In addition there will be damage in other areas. So be sure to pay attention to the order of operations when the crusher is to start crusher, then fill added raw ore. 2. Any of the crusher are all its scope, the sand is the same, it requires the added thereto ore feed size can not exceed a certain size, if too large, will make the raw ore sand clogging machine feed port. Then because of the need to clean the machine ranging and affect production, then it will because of heavy damage to the impeller and in need of repair stone to use. Third, the equipment is to be maintained, or wear each other within the machine iron is very easily damaged. Sand in the application of a period of time necessary to check whether the need to add oil, so as to make more long-term use of machines. Fourth, the sand is held together by screws, often violent movement will loosen the screws. Sand ring if abnormal during use, it is necessary and timely shutdown for inspection. Find the cause of the ring, and tighten. River gravel sand machine professional for river gravel sand equipment, which can be used for sand production lines, industrial sand, etc. is leading an efficient system of sand equipment. Application Performance add new river gravel crusher jaw crusher and vibrating screen composed of sand production line is very superior, low production costs, the price is not high, simple operation, high production efficiency, especially for small and medium sized artificial gravel pits . One advantage of river gravel Sand: Sand is the type of river pebbles (pebbles Sand) lithotripsy machine with a new design, compact, highly prominent small, so feeding and nesting, repair and replacement parts are very convenient; two: the River gravel sand machine to ensure product uniformity, no oversized particles, and the smashing reduced to a minimum; three: the river pebbles Sand has broken, the double effect of screening on the roll crusher reduce construction and operating costs, four: a river pebble crusher have double overload protection system that allows the machine running safe, reliable, five: a new river gravel sand tooth plate and comb plate structure, the product size adjustable, truly a multi-purpose machine pebble Sand, six: River gravel sand is the introduction of new processing technology, the tooth portions abrasion resistance, long life, low cost. River gravel crusher Introduction: river gravel crusher is suitable for crushing soft or medium hard and extremely hard materials, shaping new Sand, widely used in a variety of ores, cement, refractories, aluminum where the soil clinker, emery , glass raw materials, mechanism building sand, construction aggregate, artificial sand and all kinds of metallurgical slag crushing and coarse grinding operations, especially for silicon carbide, carborundum, sintered bauxite, the US high sand hard, special hard and corrosion higher than other types of materials crusher production efficiency. River gravel crusher features: small size gravel discharge, grain type uniform, large capacity, long life hammer, supporting small power, and change three fractured into two broken, process simplification, simple structure, easy maintenance, operation smooth. Equipment investment is lower than the same size of the traditional technique and equipment 35% -50% higher than the same scale output efficiency of traditional technique and equipment 35% -50%, with limestone as an example: one product size ≤5mm accounted for more than 85%. Run maintenance costs lower than the same size of the traditional technique and equipment 35% -50%, widely used mechanism for aggregate, cement, refractories, metallurgy, chemical and other industries.
