Ball Mill &Horizontal Classifier Production Line

• Technical Features

Brief Introduction
The whole process of the technology ensures that the emission of dust is lower than 40 mg / m³ and 20 mg / m³ after production, by adopting the combination of dust collector, draft fan and Pneumatic Conveying System, the strict control of every dust point, and the use of high-quality filter material. The equipment can prevent dust leak and make the whole technological process negative and clean.
Features of Main Device
Ball Mill
☆Designed to the standards of ultrafine mineral manufacturing.
☆Optimized length-to-diameter factor of ball mill
☆Grid plate at the end of the ball mill discharges powder fluently, no dilating and no necessary to cool the tube
☆Grinding medium chosen according to customers’ product, high filling rate and efficiency
☆Perfect match between drive station and energy consumption of grinding, energy saving to the fullest extent possible.
☆Forming a closed system with classifier, with negative pressure transport, without powder pollution.
Classifier
☆Using HFW multi-rotor classifier.
☆Precise procedure control to ensure good top-cutting.
☆Cleansing air adjustable to improve classifying efficiency.
☆Optimized rotor design for energy saving.
☆Diversified particle distribution by different arrangement of classifiers to satisfy different techniques requirement.
Dosing System
☆The material feeding of ball mill is controlled by precise dosing system, and then when density changed stable feeding still can be assured.
☆The material feeding of classifier is controlled by precise dosing system, and interlocks with outlet of ball mill, to make sure the stability of system operation and particle size.
☆Precise dosing pump would spray grinding aid by precise time and dose according to the requirement of particle size.
☆Both the silo and bucket elevator are installed with level indicators to achieve automatic control of the whole product line.
☆PLC control device is used to indicate clearly operational status, normal or wrong, and very easy to operate
Environmental Protection and Noisy Regulation
☆Membrane filtering bag is adopted, and the rate of pollutant powder discharge is lower than 20mg/m3.
☆High performance silencer is adopted, and the noise is lower than 80dB(A).
☆No wastewater would be released.The cooling water in the bearing of ball mill could be used recyclingly.
scope of arrangement:
1、 Soft material: calcite, marble, limestone, barite, gypsum, slag etc.
2、 Hard material: quartz, feldspar, carborundum, corundum, fine cement, Zircon, etc.
