Working Principle, Parameters and Price of Bentonite Double-Bag Packaging Machine

The core advantage of the bentonite double-hopper packaging machine is that its speed is 30% to 50% faster than that of the single-hopper type. It is suitable for medium and large-scale bentonite mines or processing plants. The following is a detailed introduction to the working principle, parameters and price of the bentonite double-hopper packaging machine for your reference.

I. Working Principle (Alternating Double Hoppers, Non-stop Operation)

Dual independent weighing hoppers: A and B weighing hoppers

Alternating work:

A hopper rapid feeding → fine topping up → weighing completed

While A hopper is discharging and bagging, B hopper starts to be filled and weighed.

When A hopper is emptied, it immediately returns to its position for refilling, and B hopper finishes bagging.

Non-stop cycling → Efficiency doubles

II. Core Structure (Specialized for Bentonite)

Feeding: Double-screw variable-frequency pushing (anti-sticking, anti-bridging)

Weighing: Dual weighing hoppers + high-precision dust-proof sensors (IP65)

Pneumatic strong bag clamping (dust-proof bag opening)

Control: PLC / intelligent instrument, automatic coarse / fine feeding, automatic peeling, error compensation

Optional: Pulse dust removal system (must be equipped with bentonite), automatic bag sewing, conveyor line

III. Key Parameters

Packaging weight: 10 - 50kg (commonly 25kg)

Accuracy: ±0.1% to ±0.2% (approximately ±20 to 50g for 25kg)

Speed: 300 to 600 bags per hour (approximately 150 to 300 bags for single bucket)

Power supply: 380V three-phase

Material: Contact material 304 stainless steel (anti-corrosion, prevents bentonite from caking)

Air source: 0.4 - 0.6 MPa (for pneumatic bag clamping / valves)

IV.What is the price of the bentonite double-bag packaging machine?

Basic semi-automatic (manual bagging): 45,000 to 65,000 yuan

Double-fighting main body + weighing + bag clamping + control

Standard fully automatic (including dust removal + sewing + conveying): 70,000 to 110,000 yuan

High-end customization (all stainless steel, explosion-proof, remote monitoring): 120,000 to 180,000 yuan

Optional equipment: Dust removal - 10,000 to 30,000 yuan, automatic bag loading - 30,000 to 50,000 yuan, palletizing machine - 80,000 to 150,000 yuan.
