Construction Waste Regenerative Technology Received Affirmation

At present,through sorting, rejecting and crushing, many salvaged materials in the construction waste can be reused as the renewable resources. Scrap steel, scrap ironscrap wire and other metals can be processed for all kinds of steel products by sorting, concentrating and resmelting. The abandoned wood can be manufactured for artificial wood. Bricks, stone and concrete can replace the sand to masonry mortar, plastering mortar and making concrete cushion after crushing, also can be used for making the building materials such as paving brick, lattice brick, building blocks.

Because the construction waste is piled up together, and the worksite is limited, whats more, the traffic is also not convenient. So Hongxing company mobile crushing plant is the best choice for the construction waste disposal. Firstly, this equipment integrates the move, crush and screen. Moreover, it can finish the multiple-stage crushing for the large materials. In addition, portable crushing plant is convenient, flexible and strong in mobility, and the space required is small, so it can save a large construction capital. Raw Materials can be broken at the locale without being transported again and also can be moved with the promotional exploitation of the raw material, which saves a large number of transport costs. Flexible configuration can install the mobile crushing plant that meet the crushing requirements for construction waste.

It is the necessarily trendy tendency that the construction waste regenerative technology in China has certain technological base. No matter the research in the lab or the application in the market, it has a certain achievement.

In the Working Process of Ball Mill Maintaining

To ensure the ore grinding process on the rails, the operator should check, maintain, and adjust the ball mill, its subsidiary facilities, working index, and the output quality. The main contents of inspection and ball mill maintenance are:

1. Grinding load inspection. The ore grinding load contains the original feed quantity and the sand return quantity. To ensure the constant, stable of the ore grinding load of ball mill is the important factor to achieve fine ore grinding effect. a. Keep the ore feed quantity constant and stable and check the ore feed quantity regularly; b. Observe the change of ore feeding granularity at all times, adjust in time and try to keep the material in feed bin more than in discharge bin; c. Watch the situation of sand return and moisturizing, to keep balance among the original feed ore, sand return, and overflow; d. Notice the change of motor, electric current, and the ball mill sound so that you can judge the ball mill load situation by that and eliminate the bulging in initial phase.

2.Inspection on the equipment and its subsidiary facilities. (1) The ball mill inspection: a. Check the loose screws, the loose, broken screws on the lining plate in particular, which may lead to leakage; b. Check the wear pattern of the sand return spoon head; c. Pay attention to the coarse running and ball vomiting of the ball mill discharge. (2) The oil feeding system inspection: a. Check the oil pressure constantly to keep it within the range of 1.520kg/cm2;b. Check the oil mass and temperature, and the temperature should be less than 30 degree centigrade; c. Check the king journal oil flow distribution of the ball mill to keep them well-distributed; d. Check the viscosity and cleanness of the oil. (3) The motor and electrical appliance inspection: Mainly check the motor temperature and make the temperature rise within the allowable value. (4) The Classifier equipment inspection: a. Check the blades of the Spiral Classifier to make sure all is on and the rolling is stable; b. Check whether the whirlcone feeding pressure of ball mill is stable, and there are leakage or clogging.

3. The ore grinding graded product quality control inspection. The ore grinding product quality of ball mill mainly refers to the quality score and fineness of the grading overflow which has direct influence on the follow-up separation process and needed to be measured, observed, test, and adjusted frequently

In all , the operator of ball mill unit move around, check, test, adjust, observe frequently, and notice the change of sound to make sure the ball mill unit is in the best working condition so that a fine ore grinding effect can be achieved.
