The machine can only be operated after the structure and working principle of the spiral classifier are clear. After the spiral body rotates, it can start to feed ore slurry, gradually feeding the amount of ore. When the spiral body is in working state, if it encounters special faults such as jamming or overload), it must be stopped immediately, immediately lift the spiral body out of the slurry surface, never allow the spiral body to be pressed in the slurry, and quickly open the mine valve to avoid siltation. When starting again, the spiral body must be lowered to a certain position in order to rotate the spiral body. If the machine needs to be stopped during use, the feed should be stopped first, and the operation can only be stopped after the material stage is graded and there is no material in it

All lubrication points are lubricated with sodium-based grease or calcium-based grease. Each shift should check whether the lubricating oil inside the reducer is on the marking line of the oil needle, and change the oil every 6 months. Always check the lower support or intermediate frame bearings, bearings, sealing rings for wear and damage to the bearings for timely replacement. Bearing lubrication must be filled with high pressure oil into the bearing with a manual dry oil pump every 4 hours to maintain the sealing performance of the bearing

Plastic Pyrolysis To Oil Plant(Plastic Pyrolysis To Oil Plant: is an ideal equipment used for recycling waste plastics. It adopts the latest pyrolysis technology by which plastics can be fully converted into useful resources(Plastic Oil and Carbon Black)

Final Products of Plastic Pyrolysis To Oil Plant include Plastic Oil and Carbon Black,The plastic oil can be widely used as fuel oil in many industries and can also be refined to diesel oil. The carbon black can be used for making construction bricks with clay or used as fuel. By the extra gas recycling system, the combustible gas will be recycled to heat the reactor as fuel, which will save energy for the whole recycling process of plastic

Plastic Pyrolysis To Oil Plant is suitable for Waste Plastics(include all kinds of Waste plastics), Such as waste acrylic (PMMA), PE (price is high, generally used to make plastic particles), PET (transparent bottles, try not to use), PVC, PP( disposable cups, try not to use) and all kinds of waste nylon products

The pyrolysis process of Plastic Pyrolysis To Oil Plant is very simple and easy to understand. It refers to the thermal decomposition of waste plastics at high temperature in the absence of oxygen. Totally sealed design can guarantee the whole process is very environment friendly. When the process is finished, we can get plastic oil, carbon black and a little combustible gas. And all the end products have a wide range of applications

② Energy saving: In the process of Waste Plastic to Oil Plant, some combustible gas can not be converted into oil liquid in normal temperature and pressure, which could be recycled to the bottom of the reactor for reheating through the pipe of tail gas. In this way, it can avoid the gas contamination and save the fuel energy

③ High-efficiency: The structure of reactor for the pyrolysis process is 360-degree rotating. This special design makes the bottom of reactor heat evenly, which lengthen the service life of reactor as well as improve the pyrolysis speed

what's the future of the construction industry? | world

Unlike other industries, the Engineering and Construction sector has been slow to adopt new technologies, and has certainly never undergone a major transformation. As a result, productivity has stagnated over the last 40 years, or in some cases, even declined

This unimpressive record looks set to change very soon, and very dramatically. In fact, profound changes are already taking place – though not yet on a sufficiently wide scale – in many aspects of the construction industry. The writer William Gibson’s famous phrase fits the industry perfectly: The future is here today – it is just not evenly distributed

The key is digitalization. More and more construction projects are incorporating systems of digital sensors, intelligent machines, mobile devices, and new software applications – increasingly integrated with a central platform of Building Information Modelling (BIM).

The challenge now is to achieve widespread adoption and proper traction. Wherever the new technologies have properly permeated this fragmented industry, the outlook is an almost 20% reduction in total life-cycle costs of a project, as well as substantial improvements in completion time, quality, and safety

Technological advances are now revolutionizing almost all points in the life-cycle of a built asset, from conceptualization to demolition. The chart below shows the relevance of digital technologies along the engineering and construction industry’s value chain

Digitalization is transforming all three major life-cycle phases of construction projects. Consider the following scenario – no longer futuristic, but “here today”, though its building blocks are still distributed patchily over disparate projects

During the Design & Engineering phase, BIM identifies potential design clashes and constructability issues, thereby averting costly corrective rework; and it improves the tendering process by making the information more transparent and accessible.

An interesting example is that of Crossrail – one of the world’s largest and most complex infrastructure projects, building a major new underground line across London: the designers and engineers are using a centralized set of linked BIM databases to integrate about 1.7 million CAD files into a single information model

During the actual Construction phase, drones survey and inspect the construction site. 3D printers prefabricate many of the building components. GPS and radio-frequency identification (RFID) are used for tracking the materials, equipment, and workers, in order to then optimize flows and inventory levels. Robots and autonomous vehicles do much of the actual building work. 3D laser scanning or aerial mapping is used for comparing work-in-progress against a virtual model, thereby enabling prompt course corrections and minimizing corrective work.

During the Operations phase, embedded sensors continue to monitor any given part of an asset, checking for deterioration, facilitating predictive maintenance, and continually updating a central database. Augmented reality is used for guiding maintenance crews.

Big data – on traffic movements, electricity consumption, and so on – are collected digitally, and are subjected to advanced analytics, in order to optimize decision-making and generally boost operational efficiency.

By way of illustration, consider the approach taken by the Japanese building service provider NTT Facilities to the inspection, maintenance and repair of their R&D premises: by integrating the BIM model into the building’s facility- and asset-management system, and making intelligent use of this combined resource, the company was able to reduce the cost of operations and maintenance by an estimated 20%

On average, uptake of these transformative technologies has been slow initially. They have faced some resistance to adoption, and some companies that do deploy them have struggled to capture all the potential benefits.

what's the future of the construction industry? | world

Within ten years, according to our estimates, full-scale digitalization will lead to huge annual global cost savings. For non-residential construction, those savings will be $0.7 trillion to $1.2 trillion (13% to 21%) in the Design & Engineering and Construction phases; and $0.3 trillion to $0.5 trillion (10% to 17%) in the Operations phase

Note that the productivity gains will vary not only across the life-cycle phases but also across the sub-sectors: vertical, industrial, and infrastructure. The chart below, based on a study of construction projects from each of the sub-sectors, shows the variation in detail

The gap between digital leaders and laggards is widening – for construction companies themselves, for technology providers, and also for governments in their role as project owners and regulators. All these stakeholders need to master the dynamics, upgrade their competencies and investments, and adapt their processes and attitudes, or risk losing out competitively

top 7 sustainable innovations driving the circular economy

In the drive to creating a more sustainable planet, the circular economy is a growing force for change. The regenerative nature of reinvesting resources and waste products back into sustainable production means that businesses can operate more efficiently and with less negative environmental impact. For example, there is enough food produced across the world to solve world hunger, yet so much of it goes to waste. Innovations such as the foodbox described below help to alleviate this drain of resources. Other means include using waste products to create textiles or even building materials. These curated innovations outline how sustainability and the circular economy can work together in the drive for positive change
