Case Particulars

Introduction

This project is mainly used to process the furnace bottom slag and fly ash discharged from Wuhan Iron and Steel (Group) Company (WISCO) self-provided coal-fired power plant.

The processed products can be widely used in embankment, concrete admixture, soil modification, cement, asphalt mixing station and other fields. Vipeak provided professional technical solutions and rich successful case support during the bidding process of WISCO's project, which won the customer's recognition and trust. The grinder grinds secondary ash with a capacity of 9t/h.

The raw materials in the hopper are transferred to the grinder by a quantitative belt feeder. The ground products are collected in the buffer silo and then transferred to the existing fine ash warehouse under the positive pressure of a silo pump. The grinding system is a closed-loop system. After the raw materials are milled, the mixed powder is blown by the wind of the blower, and then sorted by the built-in classifier. Fine powder is collected in the cyclone powder collector and coarse powder falls into the grinding chamber. The wind is separated from the top of the dust collector, and then returns to the blower for recycling. Part of the gas is purified by a bag filter and discharged into the atmosphere. The entire system is under PLC remote control.

Configuration Parameter

Major equipment
European Type Strength Hyper Pressure V Type Grinder	It is a new type high-efficiency and high-end grinder designed by Vipeak engineers by combining client demands with actual performances. Compared with traditional suspension pendulum grinders such as Raymond mill, high pressure pendulum mill or trapezoid mill in the market, this V-type grinder has many advantages, including constant and stable working area, bigger grinding force, higher capacity and lower energy consumption per hour. The V type grinder has obtained a number of patents.
Screw Conveyor	It can be used as a link between main machines to achieve continuity and automation of the production process, improve productivity and reduce labor intensity. It has the following advantages: a large conveying capacity, a long conveying distance, a stable operation, no relative movement between the material and the conveyor, low noise, simple structure, easy maintenance, low energy consumption and standardized components, ect.
Silo top dust collector	It is a high-efficiency and environmentally-friendly equipment developed by Vipeak R&D staff on the basis of long-term experience in mining crushing and grinding equipment, dust collecting and powder collecting fields. It can meet the increasingly strict requirements for dust emission standards at home and abroad.
